Can I find fault with the DJI Digital HD FPV system?

- Опубликовано: 11 окт 2024
- Pitched as a game-changer, DJI has launched a new Digital HD FPV video system and sent advance units to selected people. Here is s sneak preview of what I found inside the box on my bench and my thoughts on the pro's and possible con's of this new system. Go over to RCModelReviews for more information to be uploaded shortly and the "Glass to Glass" test of FPV system latencies.

You've hit the nail on the head with the changes in latency. I'm editing an update video on why I'm not switching over. With analog as the signal deteriorates we get static. I can fly through static. As the signal deteriorates on DJI it has increased latency. Today I saw latency in the goggle as high as 400ms then 900ms when it froze.
How are you liking that Rode Wireless go? I had one and had to sell it cause the mic preamp was too hot. I was peaking it all the time with the built in mic and lav mic. I've gone back to lav mic and the zoom H1N.
Also FYI Tommy and Me are no longer affiliated with Rotor Riot. But, yeah I did put an affiliate link in my bio.
Thanks for the confirmation Kevin, much appreciated. And as for the Wireless Go... it rocks! Best mic setup I've every used, so convenient. I'm going to get another one and a splitter for my mic input so I can do interviews with one going to the left-channel and the other to the right channel. Fantastic value when compared to the other options ont he market.
Hopefully the tech will improve. I mean flying FPV in crystal clear HD is sexy. But I think I'll wait for the Banggood version. I love my taranis x9D too much.
Very smart man found this watching stingerswarm
Hope you do get your hands on one Bruce, Ironically you've put more thought into than most of the people who have them!
EDIT: Please do the latency test ASAP Bruce 👍
Bruce: I’m not relevant
Every person involved with fpv ever: clicking on Bruces’ video feverishly for technological advancement truths.
DJI: crickets
No. Youre not a major influencer Bruce. But your honest and realistic. Which is why I have tuned into this channel for some time. If I want hype I go elsewhere, if I want realistic input and opinion, I come here.
If DJI were smart, they should have sent you their tech. I just made a comment on their video to suggest sending one to you. Everyone else should as well.
*you're
Well done sir. Will you be correcting every grammar and spelling mistake throughout all the comments to this video?.
@@professionalidiots101 Well done sir. Will you be making inane responses throughout all the comments to this video?
No sir, I believe that my point has been made.
The problem with this whole hype train concerning new gear Bruce, is when certain, famous and almost most notable people in the FPV community have something to gain in some way form or fashion, there is no true and factual reviews because they no longer have an objective perspective, their motives have been skewed. When you've turned a fun hobby into a living, most reviewers no longer can be trusted with their alleged "objective reviews" as they tend to benefit from sensationalizing the positive aspects of a potentially flawed product, while downplaying or not mentioning the negative aspects. It's a shame but I've learned to live with it and know better by now, which is why I depend on you and your channel to shed the facts and light on the subject, not these other shills that sell out for a piece of the pie.
I find, as all the reviewers go, Bruce and Andy Rc are probably the best at being mindful of what may be problems / mistakes in a product, as well as the successes. I am more than interested to see where this goes....but this is , or looks like, the first viable DVT ( digital video transmission) I've seen, and please don't say Conneix. I said viable. DJI, I won't buy this one, but I find it interesting the first FC compatible with this system was announced less than 24 later. Look for a TON of systems coming out , as copies , knockoffs, and work arounds will happen almost instantly.
Bruce, I feel I get a lot of value for my little 5$ a month. Keep it up !!
Dronemesh is the worst. Like a bad used car salesman.
@@jeffw8369 dronemesh def the worst
@@TheAwflores GFY troll 😂
Has any company other than eachine sent out prototype units before production?
It's like any other move is outright stupid business practice to be honest.
great insight Bruce. I have every intention to test out how well it plays with analog in the same space. I asked DJI for a channel listing so that way I can purposely get an analog channel to be as close to the frequency as a DJI channel. It very much reminded me of the times when everyone in my group HATED the guy that had a dirty VTX that only had boscam channels (because he'd blow everyone away) so I totally get the concern. The power output is controllable (and yes max is currently 700mw). I just got a response from them saying that diopters will be available soon (that was a common question i got). I do share concerns about the "digital cliff" and what happens when you're pushing it's signal to it's edge (either from range or having objects to penetrate through) because it's scary LOL and I would most certainly be hesitant to do anything sketch (like dive a gap) when it's at that limit. In it's current state, I would have to do a "test flight" first and see how the system reacts before doing something sketch (whereas with analog, i'm pretty confident about hitting a gap or something first go around if the video is reasonably good). But with this, you just don't know if that wall or tree is "just enough" to change the latency an affect your flight. I suppose in a way, just like when you first start off with analog it's about knowing your system's limits. This is no different. In fact, a good analogy might be the difference between flying 4s and 6s.... with 4s... you can feel the juice run out. Whereas on 6s, everything is awesome and then you just fall out of the sky when you run the pack down a certain point lol. At the end of the day, I'm excited that this technology is here and at a point that's worth flying. The previous connex offering looked good, but flying it was another story (just like you mentioned and why i don't think it ever caught on). And when they addressed the latency issue, it brought the image quality down so far that you might as well go back to analog. I can confidently say that this DJI system doesn't exhibit any latency (in low latency mode) and I think it has an image that is better than Connex's "prettiest" mode. And with Fatshark announcing their HD offering.... it's an exciting time in the world of FPV!
According to Tony from IRC, the DJI uses the Raceband within about 20mhz. 1-5 match up, but 6, 7, 8 are 7, 8, 6 respectively if I remember correctly. Contact him for more info on that. They (DJI) claims it should still work with timing systems as well. The antennas are LHCP as well, but you likely know that.
I bought the dji HD racing edition goggles combo, I fly fpv Rc planes and gliders.
On flying wings the latency of 50ms makes it a bit challenging, but on slower planes gliders it works great. The difference digital HD picture has made is phenomenal, with a flying experience that brought a new dimension and joy to hobby for me.
The second advantage is having a non static rock solid reliable signal for up to 4km gives me the peace of mind to sit back and enjoy the experience. This new FPV system sounds great and will also appeal to Rc plane enthusiasts. I can’t wait for your review.
If they have that much confidence in their products, you're the very man to sent their kit to for a no-bullshit genuine review :)
From my testing of it personally it’s amazing, will be using it in my cinematic and filming rigs going forward and for live streaming at events
Yeah, I watched you having *FAR* too much fun in the RR video :-)
But not for racing?
man this guy has been a big help in the beginning of fpv think we dont give him enough creddit for it
You're the one I trust the most when it comes to these things. If I was DJI, you'd be the first one I'd send one to.
Nope, DJI Want us to shop til we drop. So they did the right thing and sent it to Mr TV SHOP himself, the excited, "everything is awesome" guy Le Drib, trying to tell us it is cheap, low latency etc while not testing the system more than a few flips and flops flying like beginners. I bet none of the RR crew will fly this on a daily basis any time soon. Just wait ...there is something even more frightening lurking in the horizon...when bad boy, gamechanging master of all UAV Futures gets hold of the DJI system, it will be the greatest OMG,WooT , gAAAAH! system in the galaxy instantly.
Can't wait for HD FPV, am eager to test the new system DJI has setup. Hopefully it'll push Fatshark/ImmersionRC to release an HD module for their HD0's
Did you get the same box as me Zoe? :-)
@@xjet A big box of nothing from DJI? yes hahahaha
They missed a golden opportunity for a great marketing campaign by not getting you onboard Zoe. Imagine the catch-cry as you 3D'd your DJI-FPV-equipped drone in front of the world's cameras... "DJI, turning the drone world upside down". Oh well :-)
I saw a Facebook post from Fatshark yesterday which is a HD system that mounts on a 30x30 stack and compatible with current Fatshark goggles and transmitter etc.
@@johncitizen3361 Holy shit, the question is who came up with it first, because you know there was some corporate espionage going on haha! That fatshark system is going to be so much better the goggles were the one reason I'd never buy the DJI and it looks heavy. I'd be using it mostly on fixed wing with efficiency and weight in mind. Cruising some mountains in HD is going to be amazing now we just need IBCrazy to make some antennae.
Bruce is the guy I trust most when it comes to reviewing stuff.
Your really got me at the beginning. I thought DJI really sent you one ;)
Thanks for mentioning my latency tests. Actually I also tested glass to glass, with some different goggles, don’t remember if I did a video about it... fatsharks were maybe 5ms DJI goggles (the mavic ones) were quite high, ev900 were also at 100ms.
I think when I tested FPV blue digit system I also tested glass to glass.
Mid air latency test by rolls - clever idea! Brilliant thinking about this one, and also how bad variable latency can be for the top pilots.
Average pilots might not have an issue with that tho.
This cam module for me is competiton to something like a split rather than a GoPro. And it wins against a split!
This cam however will be very likely be affected by jello vibration issues.
When you think about jello countermeasurements: nd Filters to reduce shutter times... this sys goes up to 120fps. So really short shutter times here...
Brilliant video, might be the best video about the DJI goggles I’ve watched till now ;)
Greets, Mario
Brilliant ... DJI engineers no doubt have worked some good compromises to make digital work in a difficult environment but the reservations you have raised are very real ;-)
framerate and latency are not inversly related. You can recieve one image 1 second after it was taken. If the next image comes 12s later, but still arrives 1s after it was taken the latency is the same 1s.
The feed can drop entire frames, but that doesn't effect the latency of the next frame, it only lowers the framerate.
That opening joke in the first 2 minutes is gold.
Thanks for another honest and insightful Non-Review Bruce xox ;) Food for thought as always :)
Just finished setting up my new dji fpv system and I wanted to see how my analog system worked with it. The channels are pretty much the same as Race Band except that channel 6 on rb is channel 8 on dji. When I set both up to channel one and turned them on, the analog system (running at 500 mw) was wiped out with static completely. The dji system was clear as a bell. The interesting thing that I found was that all the channels on the analog system had a number of lines running horizontally across the screen. The analog system that I'm running is a unify pro hv @ 500 mw.
Great. A perfect video for a lazy Sunday morning over 2 cups of coffee! I for one did not bother watching all the other reviews as I am at this game long enough to know the story and you confirmed it. But when I saw you had a video well that's another story! Looking forward to your "super view" video and your "latency video".
Thanks Bruce, I am glad I got it first from you. the latency issue is a big thing. you are right, if the latency changes on the fly, that is a problem I could not handle.
Rotor Riot is just a sponsor channel
Johnny Depp yup bunch of hipster weebs
They clearly showed the system not meeting the range claimed by DJI. One pilot said she could feel latency. They showed pixelation from obstructions. I didn't see any of that in DJI's ads.
@@Politicallyhomeless957 they even dissed the opentx system for being too hard to use and then the next episode they talk about pids... 8-O
Your banggood link got me an WIG lol "Middle And Old Age Men Short Straight Hair Cosplay High-temperature Fiber Wig"
Kabab fpv is an objective, reliable source
Mostly yes, but oftentimes his opinion changes weekly... So I don't get the products he promotes immedeatly
Kababs the best!! He always helps me and has exactly the same opinion on the most things.
Second one is RcModelreviews
Bardwell: I dont know ~ sometimes yes and sometimes no
But I really dont know many reviewers that are real and reliable infos
DJI PLEASE HOOK UP THIS FIDDLY LAD 'CMON!
No way I will buy it until you get your hands on it Bruce..lol And man do I want it!
Same here !! I'm waiting to see all the other companies release their versions in the coming months.... and perhaps lawsuits over copyrights, etc. FPV is just a tech drama queen, LOL !!! Spending this kind of cash on V1 is just a bad decision, IMO, unless it is extensively. tested, reviewed and approved.
Good stuff Bruce. It has gotten to the point where people should not fully trust those with affiliate links in there video description. Very sad that some people we use to be able to trust there reviews are now selling there soul for a few dollars. You are one of the handful left that calls it out as it is. Much Respect.
I kinda like the idea of xjet being the boogy man of of the RC Hobby business
Glass to glass is what I've been trying to test myself for years. I own an oscilloscope with multiple channels...I just don't have the knowledge of how to set it up and use it correctly. Very excited to see your testing results!
Your brain is fine mister! You dish out excellent info my slightly younger brain enjoys!
No technical reviewers who know their stuff got it. Bruce, JB (missing from RR’s review curiously), KG, Drone Mesh (likely cause he’d added more low esr capacitors to it)...
JB sent his unit to Drone Mesh
@@BengalCatChilli no incorrect. That was the r2teck system. I did not get a dji system.
@@JoshuaBardwell ah sorry mate. I did think that would be a heck of a lot of trust in the postal service 😅
KababFPV got one to review. He is a very critical reviewer but he gave it positive praise overall.
His review is flawed and not complete at all. He says control and video is 7ms which is not true they say video is 28ms and gets higher during signal degradation.
@@pizzyfpv true, he's usually more critical and sceptical. It's hard not to be excited about Digital FPV though.
@@islipstream yeah we are all excited 🙂
I heard FatShark is coming out with a HD system soon called Byte Frost, that will work with the HDO and HD3 goggles. I think it's smart like you said to wait until the Honeymoon is over and see what people think then. By then maybe the price might come down, and the bugs might be fixed.
Great job Bruce, I'm looking forward to the glass to glass comparison.
Spot on! There's a lot of youtube whooping about these and I'd love to have HD in my goggles, but it comes at a cost - financial and technical. The biggest problem is digital transmission stays good for longer and then suddenly dies/freezes to nothing/black. Analog degrades and we respond and fly to that. DJI are degrading by bit rate, frame, latency etc. I don't see it being adopted by the greater FPV community, but an acro enabled, tuned Mavic with this would be massive for cinewhoop use.
It would be interesting if DJI were able to incorporate rocksteady in the onboard 1080p recording. Or in other ways incorporate features of their action cam into this system. Perhaps that is coming in the future.
I'm glad you mentioned the actual footage quality, yeah I was watching Kabab's video it just gave me a sense of the many split's I've owned. Still pretty interesting tech..Great Video!
I've been keeping an eye on all the various split camera reviews & people's footage on RUclips, none of them have impressed me because they all exhibit over-sharpening artifacts (single pixel bright halos round edges such as trees against the sky), until I saw the Tarsier...
I now have one attached to a micro quad, printed a mount a few hours ago, 145g AUW, next step is wiring it up :)
@@licensetodrive9930 Yeah that's the bottleneck, compression/bitrate, the DJI stuff looks over sharpened for sure because of the recording bit rate, no log video recording format and whatever codex they are using. This is why professional HD systems from Parallax cost 5k to start...but DJI is determined, they will get it for sure, they already bought Hasselblad, use Sony/Panasonic's platforms, it neat to be apart of a growing and moving experiment.
@Duncan Stewart Yes with the investment DJI are making in the camera sector it's going to be very interesting to see how far they can/will take this FPV tech. KababFPV made some good points about how its realtime HD transmission (from such a tiny device) could be used for sports on television, which is a staggeringly big market compared to quadcopters.
@@licensetodrive9930 Well the funny part is professional HD Video systems for broadcast usually cost anywhere from 5K to 15K individually so at what 500 bucks this will disrupt the industry for HD video transfer, Connex and Parallax are the same companies or using the same tech, so it will be interesting to watch. What we need with this a global shutters for the cameras.
You made a good point on the variable latency, didn't think about the time it would take to adjust! Shame they didn't send you one, really.
I'm new to fpv, and have even cancelled order a couple weeks back for HDOs. In agreement over pricing, for a newcomer it's very competitive and I too would have charged more! Will wait a few months see how things develop, but HD is the way forward, for me I want the closest experience available to actual flying. Thanks for the vids
Hi we're happy to send you a pair of FPV goggles for review what's your best email for contact?
Hi, thanks for the kind offer... you can contact me by email at: queries at RCModelReviews dot com
Hi Bruce, DJI should send you their gear to review because you are one of the few reviewers (very few) on YT that can be trusted to tell the truth. If I am looking to buy something and you say good things about it, I am much more likely to buy the product. If DJI aren't confident enough of their product to send it to you to review then that would put me off it in the first instance.
DJI - send this fellow a unit, please.
Thank you for making this. I can't stop staring at the Rode wireless go.
Yeah, I was going to get a separate lav mic to plug into it but it's just so convenient to clip it on and go without messing around :-) Great mic, love it.
@@xjet It does sound great really. I may need to get a set or 2.
You're killing my OCD with that workbench
Can't wait to see this stuff in Hollywood and sports. Great stuff!
To be fair StingerSwarm did mention he thought the camera angle was different to what he normally runs and that was effecting his flying style.
You might thank your patronising fans by reading them chapters of an audiobook. Poll them for which one.
It will give you somthing to do on all those rainy days next summer : )
Thankfully, you don't need the radio at all, just the goggles, air unit and cam. So 700-ish bucks. Looks impressive.
Spot on! As usual....happy flying
Once you get one Bruce, and YOU Will in the near future, please cover how us Fixed Wing Guys can possible use this on our RC airplanes. Seems that all of the "Other Guys" selling this product on their channels, have not discussed this application. The mile and half range is acceptable as is for me. Would be nice to just use the camera, VTX and Goggles in a stand alone fashion. I really don't need another Transmitter. Keep up the good work!
Good job Bruce. You're always thinking Ahead. You're always my favorite channel. God bless
I would like to try this on an FPC RC car. How it handles situations where the transmitter is close to the ground and behind objects will be useful to know.
Bruce really finding that sweet spot between clickbait thumbnails and titles that make you mad, and clickbait titles and thumbnails that just make you go "well I guess he had to do that". Hopefully you get a chance to do a proper test and review...you always give things a real in depth going over.
I have pre ordered FPV Blue. It's been in development for a few years now and it looks like there going to produce a great product If you are interested in getting a HD system you should check it out.
Check out the community page on my RCModelReviews channel :-)
Thank you very much Bruce! You r great! I will be waiting for version 3 may be then !
Intelligent discussion and analysis, Bruce. Thanks.
I watched KababFPV's review which was the best over all so far and was not a hype fest at all. He had a very sober overview and brought up many concerns. I ordered the goggle and 2 air unit package right after his review. All I care about is my FPV feed. I don't fly in very challenging RF environments and Im very interested in how it feels in the air compared to my current low latency setup (Crossfire, TBS VTX, and Foxeer Predator V2). I fly skyzone box goggles and have bought and sold Aomway Commander V2's and FS HDO with Rapid fire. Neither of those were a big enough improvement so I sold them. I also have Orqa's with rapid fire on the way in September (hopefully!) its going to be fun to see what flys best and gives me the best FPV feed.
LoL @ the empty box from DJI. 😂
Variable latency could do with audio cue "submarine ping". Ping pong every time the latency changes. It may be possible for the pilots to train on sound cues. Imagine a tick tick...played less than a tenth of a second apart and scaled to make it easier.
I love the way you do your reviews, and in my opinion it seas a lot wen a company had the nads to send you a product for review! I know I I had a product I'd send it your way for review and improvement before I send it to a customer!
🥃Cheers🍻
I think many will continue to put a gopro on for more reasons than just superview, namely that jello you often get from hard mounted FPV cams. the value in the dji hd system is more about the realtime video quality than the recorded video, imo
Good vid, looking forward to your glass to glass vid , thanks
I think DJI should hire you. I've seen some of these orgasming reviewers with their $1000 DJI and they don't have a friggin clue about what matters. You nail it on all real world issues. You SHOULD be surprised they didn't send you one. You are invaluable to the industry in giving educated thought and invaluable suggestions to all the products you discuss. If DJI only had the enthusiastic children to evaluate future changes to products, they would fail. It is experienced and thoughtful people who ask the questions that effect real product quality for the long run. DJI, send Bruce a setup.
ill keep the go pro and analog for now. If it was more versatile mabye. but appreciate the direction we're heading. Thanks Bruce
Very interesting view and also entertaining ;) - I really look forward to the DJI FPV setup... but one killer criteria for me is how easy it can be unlocked to non EU mode as nobody does really fly freestyle with 25mW in the EU anyway.
DJI get this man a pair of goggles!! (expedite shipping)
There a lot more options to manage the bandwidth than dropping frames or lowering the framerate.
They most likely use variable transmitter power, increasing the power when the range increases.
They can also encode the video with less bits at the transmitter, so there's less data to transmit. This doesn't lower the framerate, but reduces the video quality. Since it's a 2-way connection, the transmitter and receiver can negotiate on what quality they support at any time.
The most advanced option would be to transmit the video in an encoding format that supports incremental quality levels: you send a low quality picture in a very robust way (ie a lot of error correction, using more bits), and then you send one or more 'refinement' data packages that add more detail to the frame, with a less robust encoding (less error correction bits). Depending on which parts of the data the receiver can decode (reconstruct with error correction if there is data loss), you get only the base quality image, or a better quality frame if more data was successfully received and decoded.
If it was me, I'd do all of the above :) .
I'd be looking into AI-based wireless video transmission :)
@@lievenvv I don't have a clue what that is 😂
On sad thing with the "digital fpv" revolution is that compatibility will probably go out the window. Dissapointed that DJI didn't decide to release a standalone receiver but hopefully something that will come in the future.
My guess is that the DJI vtx has an automatically adjusting output power. The weaker the signal gets, the more it ups the power output up to whatever the max is. I'd be a bit surprised if that were not the case.
This, and they can also play with the video encoding. Either encoding lower quality at the transmitter, or compose a picture from less information at the receiver side.
Isn't the video tx one way only, how will it get feedback on the received signal strength? And if spectating is even an option, which receiver is then the master. controller
@@stefanth8596 No it's 2-way. So the receiver can give feedback to the transmitter about signal quality / need to increase signal strength.
When spectating it's one-way though. DJI actually mentions somewhere that quality will be lower when spectating because then your Rx has to deal work whatever signal it gets without having the possibility to give feedback.
@@stefanth8596 There is a digital link between the goggles and the "vtx". Within that signal I assume there are multiple parts. One of those would be telemetry data that goes both ways. The paired master goggles talks back to the vtx telling it how good the signal is. That is why they say the spectating goggles may have worse performance, because they are only watching, not sending data back to the vtx.
@@5zero7RC thanks for the explanations.
Biggest difference I can see is that with an analog setup if you start losing signal or there is interference the pic goes snowy or fuzzy, but most of the time you'll be able to make out a horizon through the murk and save yourself. With a digital setup you'll either lose frames, so you'll be fighting very high variable latency, or it'll just freeze and you're blind.
Fat shark already responded with something called byte frost, don't think they're exactly quaking in their boots
Fat Shark ought to be quaking. There are a fair number of pilots out there (and I'm one) who feel like Fat Shark has been resting on their laurels for, well, mostly forever. At this point, simply based on the companies, the only thing stopping me from 100% voting with my wallet for DJI over FatShark is that I'd rather not support Chinese companies when I don't have to, but as far as Chinese companies go, DJI has a great reputation. FatShark, no not really.
Now, of course, I won't be picking up either until I see some trusted reviews, and they're actually out in the market for a while so that the hype fades, and reality sets in. If I were to place a bet now though, I'd say after that time period, it will be DJI standing tall, not FatShark.
A wireless setup with superior image quality goggles like dji will be far better than running a ground station and HDMI cable into old fatsharks. I know, I own the Connex system and honestly it's such a pain in the ass to setup/carry/pack up everytime. The fatshark screens are also just not good enough to view a 720 image at its best. I'd choose a wireless setup anyday of the week. It will never be as good as the dji setup simply because the hardware is not there in current goggles. And for people with hd3 I wouldn't bother. I have hdo and hd3 and yeah hd is a big improvement but the screens are just not good enough to make it anywhere near the level the dji goggles display. Maybe a set of orqas will be the go but then you still have a HDMI cable hanging off your head. I just can't see a ground station being competitive while using current hardware.
Well, to be fair, DJI has a huge research and development team. FPV gear won't be their major focus, but the tech is relevant to photo drones as currently they have quite some latency. Looks like DJI is released FPV gear as a testing platform for their other products.
i have flown next to a phantom 3 ,.. 5.8g is full of rf interference from they'r TX. impossible to fly almost.
Darn, looking at the "DJI" box and i am thinking this could have been Bruces first LIVE audience show! Laurie
At AUS $1499 for the DJI FPV Fly More Combo (Mode 2), down from $1639, not sure I’ll be racing out to buy one. But I might some day. Thing is I was able to purchase a secondhand S1000, A3, and Lightbridge 2 Drone for $1500 which I think was a good deal. DJIs new FPV system not so much. But HD is what everyone needs.
Seems to me this would benefit the fixed wing FPV market.
Hay Bruce, remember than challenge on CE to FCC, well I went there :) Put a video up today on FCC Hack, Have fun folks.
Excellent video Ian, I'll give it a mention next time I'm ranting ;-)
I'm interested in what Bruce has to say about this system given he went down the route of designing his own HD system a while back and has some technical knowledge regarding how they are implemented. Basically very powerful processors doing compression/decompression on both ends as quickly as possible (and sucking up a fair amount of watts in the process). Did they burn the software as chips? Or can it be updated as they come up with more efficient ways of implementing it (e.g. FPGAs). Or is it actually more traditional software and genera purpose processors?
Good stuff Bruce, especially the thoughts around variable latency.
I don't think this system will replace a GoPro for freestyle guys, they won't be happy with 1080p so I don't think the lack of superview is a real shortcoming.
Also, with your comment about Kevin and his dodgy flips and rolls, I disagree with you regarding latency being a larger issue than rates. Snap rolls and flips are totally muscle memory and it looked to me like he was flying rates he wasn't used to.
Just another comment about the latency: Yes you can adapt to higher latency, but only for stuff you can see coming and/or know is there. Like turning into a gate, or orbiting/looping a tree. If you suddenly have a branch or pole in the frame that you need to dodge that wasn't visible before, you're out of luck cause the latency means by the time you see it you already hit the thing in actuality (or are too close to input corrections that would avoid it).
Also a low frame rate doesn't necessarily mean higher latency. It depends on the protocol. The 'time distance' between frames is obviously larger, but just cause you wait 100ms (or more) for the next frame doesn't necessarily mean that this next frame wasn't taken closer to the time you actually see it. That depends on the protocol. Digital protocols that include multiple resolution can ALSO be optimized for lower latency. But yes, most likely it has at least a higher latency, but it could well be lower than the actual frame spacing. Just saying it's not a given.
Bit late to comment, but yea. Exactly this, I have a EV300D, the goggles from 2 years ago where the reviews for them panned out badly due to the latency after they released (they seemed to have send different units to reviewers before it came out). Yet, ironically, the 300D's latency is more consistent and under normal use equal or faster than the DJI system unless you only fly in an empty field.
You can certainly adapt to it, but it won't save you from surprises. I know, I lost a drone to surprise branches.
(not to mention the DJI system is basically unworkable in europe if you want to fly legally)
Lmao on the dji share holder Bruce !
I just want a good, fast HD VTX. Bundling it to the transmitter is corporate greed. I'm looking forward for your thoughts on this system.
As I said, *we* aren't really the market for this gear... DJI are probably looking at the rather lucrative market that already buys their drones because they're simple, turnkey solutions. By including the transmitter with this package, DJI are supplying the same "super simple" solution to getting live HD video from a miniquad or other agile multirotor. It's all about "the shrink-wrapped experience" that so many people are prepared to pay for (especially when time is money).
heee walter white breaking bad... hahahaha.. good vid..now make me some crack... LOL..
Bruce, for your latency test, would you mind having a complete change of image in front of the camera, rather than just an LED turning on?
DJI presumably perform image compression, and only send the delta from one frame to the next. In other words, if the only change on a frame is an LED turning on, they will only send that portion of the image, so the total data for that image is small and latency will be very low. A complete image change however will require that the full frame is transmitted. Perhaps you can point the camera at an old CRT monitor or something and flick from one scenery to another? Really appreciate your reviews, thanks!
Yes, I'm using a light diffuser anyway to get a full screen black/white change on all the tests.
That stuff is great and in few years (2ish) it will be the new standard.
If you compare the video quality you are forgetting that a GoPro 7 is worth 400 bucks (half of the whole DJI -first version- package).
Just wait for the 2.0 version, they will blow the market.
As a racer, aside from any possible analog/digital interference and variable latency, how would analog lap timing work (if it's frequency hopping or whatever?) Would we have to go back to using the less reliable IR transponders from 2015/16? And if we could not use analog rssi based lap timers for the DJI system, we would likely all need to change to IR, unless livetime supports multiple inputs. Either way, I see the DJI product much more geared to freestyle/cine pilots. I don't remember who the racer was in the commercial. Certainly not minchan or Thomas or vanover. Yet Johnny, definitely one of the best fs/cine pilots, was at least featured in one ad I saw..
overall it seems like a very good product for freestylers (even if they still keep a GoPro on their rig), but I don't see it coming to multigp or fai or dcl anytime soon.. again though, it would be very cool to have, just don't see it in racing (as Bruce said)
Nice one Bruce.
Thanks mate i have been eagerly awaiting your'e review! I believe in race mode it goes down to 25mw
What do you think of mjx I bought I bought one a while ago I haven't put it together yet so what do you think Thomas from Winter Haven
Great minds think alike Bruce, I sent tommy a comment on his review video asking all the same questions about how well the DJI system will play with the more traditional FPV systems for both freestyle and racing. I suspect that multi GP will not allow them in races because they can't turn down to 25mw power and won't have things like pitmode which are becoming required features for racers. So these will be primarily for freestyle, the other question I had was what are the 8 band frequencies DJI uses, are they close to raceband?
I don't see this being used as a race or freestyle system. What I do see is a decent quality HD streaming setup in a neat package. Can't seem to find the wattage, but i think it's 5 watt? Also keen to see what Fatshark brings.
You're the man, Bruce!
EXCELLENT review!
La Drib mentions in his video that we fly at 30 to 40ms which is a lie and miss infomation. Based of my testing we fly at a range of more 15 to 25ms.
Everything is a trade off, so in this case the trade off with better image quality may actually lead to the "variable" latency not being as big a deal. Because you can see the "targets" of your turns and maneuvers better. We will see won't we?
wasnt the video transmitter latency on the inspire quite bad? i am guessing the transfer system is basically the same.. the inspire wasnt really made for racing so it wasnt really an issue there.. and 1000 USD? is it just me that thinks thats a bit much for camera + video transmitter/controller + remote? i can buy a mavic air for less, and a mavic pro for a bit more
but will it help Ron to do better landings?
everyone else will have to up there game,the future of fpv is going to make a big leap forward
We done! At least you give an honest opinion.
Looking for some answers between the Occusync & RE Goggles versus the DJI digital FPV system . Are they compatible at all . If so in what ways . I have invested in the Occusync & RE Goggles .. Hate to find out it’s going to be Obsolete . Any Help would be Greatly Appreciated ...
