YES! We haven’t tried this bad boy yet but we love Hollyland, we got 4 Mars 400s Pros for wireless video switching and they’re amazing! Pro tip, if you’re using an Atem switcher, Mars 400s Pro, and have an external audio input from like a mixer or field recorder, delay your audio input by 7 frames and it aligns perfectly!
@@Muljika yeah, still twice as fast as their previous 400s/pro. I use a focus puller with the 400s, he complains sometimes, but only with fast moving stuff. This is twice as fast, and for the money it looks good. The limitation of only working One receiver/ one transmitter only (ie, no multiple RX's) is the omission that makes it dead in the water for me.
Let's think live production for a second. Never had any latency issues with Teradek transmitters. As I downloaded this video and counted the frames, it seems that transmission time to screen is 4 frames, video is at 24 frames per second so the latency is around 170ms. Now if you have wireless microphones on set that are routed through an audio mixer, not via the camera that is being transmitted using Cosmo, your audio will be out of sync and a lot. But all is not lost. The latency also depends on the camera being used. For example, BMPCC6K has almost 4 frames of HDMI output latency. A camera that you are using in the test may have the same issue. The best way to test for is to have 2 identical monitors (really important, since monitors have different input latency as well) or even better, a monitor that has a picture in picture or side by side view for two input signals. Split your camera HDMI so one cable goes to the transmitter, another straight to monitor, and compare the two (do not use loop out of the transmitter!). This way the camera output latency is bypassed in a test and you can get the true latency of a video system.
I'm sending my 400s Pro system in for repair again for the 2nd time in less than 6 months. I'm planning to buy this as a replacement. Hopefully these work out better.
Taking over this space?! I think it's safe to say they fill a void where smaller productions really couldn't justify having wireless video on their sets. Solo ops or small teams, hollyland products make wireless client and director feeds finally approachable/worth it. Especially considering the teradek systems might be 3 times the price. But there is a key reason teradek is still the most popular wireless tool on larger sets. All teradek's are essentially
@@CrainerEU It's less than 1ms, most of the delay you might experience is from the monitors internal processing generally. But Tereadek's wireless is very fast.
To your point regarding the AC adapter and latency: these are VERY geared towards the live/broadcast market, and have become nearly ubiquitous. So many A/V companies are ditching 200' long SDI runs for these. I've done several shows with all wireless video (with onboard recordings as backup) that all went swimmingly.
Hollylands are extremely reliable. Teradeks are only great because of their latency is nonexistent. Otherwise, I can't stand the damn things. If Hollyland can cut the latency issues to almost milleseconds they'll dominate.
Why teradeks are bad? Just curious. I personally never liked transmitters with latency. As a focuspuller i dont care how shiny cheap and great it is, if it has latency then i dont use it.
Wanted so share some perspective based on personal use: our church bought one of these for our roaming cam and it was great… for about 2 weeks. We get constant interference with our wireless mics and in ear systems and when you get up on the stage, loud static goes through all the musicians in-ears. Really not a fan of it in practical use.
Try switching it from “Auto mode” to a designated channel of your choosing. Find a channel that doesn’t cause the audio interference and your problem should be solved.
I have used the Hollyland 400s system since it came out for basic remote camera monitoring. No complaints for the money, and I’m sure this C1 setup would solve some transmission problems I’ve had along the way trying to work beyond line of sight in concrete or masonry buildings. Nevertheless, if the plan is to pull focus via remote, then Teradek is still worth the extra cost. The difference between 40ms in the C1 vs
An outdoor range test is good, but how does it fair in a home? If I put a directors monitor in the living room, then go a few rooms over and up the stairs, would it work?
hola que tal, tengo el HOLLYLAND cosmo c1, y una lumix gh4, no logro que conecte la cámara con el transmisor, me echas una mano? que me podría esta pasando? gracias
I bought one from their reseller, to be honest, the latency is really great on this level. Sometimes I can see the latency to 0, but an average of 0.03-0.04. If you guys are interested, you can dm me. I'm glad to share my experience with it.
Semi new to your channel and love it. My only negative feedback is that - I felt like you were trying to break up Pam and Jim when she was in art school. Love the tutorials!
HA! The Doug DeMuro reference was funny. I heard the Hollyland transmitters are designed to be dope because being in China, there are buildings and all sort of interference so the connection has to be reliable there and it's pretty much reliable anywhere. I can't remember what RUclipsr said that but it's been on my brain nuggets ever since.
Hey Doug it’s funny I get all your videos I not subscribed cause you don’t need anymore subscribers but yup they seem to keep popping up on my subscription feed.. you what I also get a text when you post a well. Sincerely the subscriber you don’t need 😎😂
Hi, If the signal enters in hdmi on the transmitter, can it be recovered in sdi on the receiver, and vice versa? On the receiver, the hdmi and sdi outputs can be used at the same time? When the Cosmo C1 is used in direct usb on the pc without a capture card, can the hdmi and sdi outputs be used at the same time as the usb capture to send signals to other peripherals? Thanks
Does this also trasmit to mobile devices? I watch a number of videos but none mentioned that so I am guessing this only transmit from camer to a monitor that the receiver is connect to. It would be great if it does so I can connect a tablet to it as well for client viewing.
The world of video transmitters is really weird now. Can anyone suggest any transmitter with hdmi/sdi loop, 0 latency and a reliable signal for less than $1500? Cosmo 600 used to be a superb transmitter for its money, but now we cant buy it and dont actually have alternatives for it. Its been a while since it was discontinued and now all we get is transmitters like this, with latency and with big price tag
Love your stuff, but in my experience, Hollyland is great until you have an issue. Customer service is a nightmare. No US-based support as far as I can tell. Every interaction takes 24 hours, emails require a class-2 code breaker to decipher and firmware updates are a huge pain. They make neat stuff, when it works. As far as this product goes, I'd lean much more toward Accsoon. Just my 0.02 - keep up the great work. Oh, and say, 'so long' to that Teradek sponsorship.... lol.
I wonder how it compares with the "Accsoon Cineeye PRO 2" wich is owned bye Hollyland as I understand it. It has great reviews. One thing you did not specify when doing the "latence test" was what camera settings you were using as it can really alter the performance. I think you could get lag down a lot if you feed it 60fps instead of 24fps.
Have you fixed the non-compatibility bug with blackmagic capture cards? Let me remind you that the 400s pro cannot be captured with a blackmagic capture card via sdi!
With that much latency, you might as well buy a product that is half the price with twice the latency. It isn't low enough for an IMag system so it sits in that middle ground of too incapable for a higher price and too expensive for its capabilities.
Actually much worse latency, from your video, and based on the camera you are using, than Accsoon on a recent iPad or iPhone. (NOT using their terrible transmitter - just the iPad straight) Not at all comparable to the latency you get from Bolt family of products or Nyrius transmitters (which are less than 1ms - both are based on the same chipset). I do not know how any focus puller or remote operator could use this system. It's complete crap.

Except, the Cosmo C1 only works as a single pair, you cannot use multiple RX units (this is what I was just told by Hollyland ). Keep your 400s's
Nice. Should do a latency test between this and wired SDI to determine if the latency comes from the unit or the monitor.
A focus pulling example would be an awesome follow up!
40ms delay is not true zero latency, Definitely not useable for pulling focus. Pretty much makes no difference than the standard
↑ This. Finally someone. Thank you.

Who said zero latency?

Perfect answer! Seems like its a competitor for accsoon cineeye 2s pro
oh, well have you ever tried to pull focus by just listening to see if something was in FOCUS! HUH HUH HAVE YOU !!!!!!!!!!!!!!!!!!!
I have one cineeye 2s pro, it's cheaper than cosmo c1 and supports multiple RX units. BTW I hope someone could do a comparison video.
Is teradek really 1 ms only? That’s insane, might be a dealbreaker for me though…

would love to see a comparison with your teradek bolt same cam, monitor.
FROM MY EXPERIENCE WITH THR MARS 400S PRO, USING THE HOLLYLAND APP ON A SMART DEVICE, YOU GET LESS LAG THAN USING THE RECIEVER WITH A MONITOR.

what're your youtube settings? a lot of banding in your videos
Been waiting a while for this one
Can we use 2 sets of Cosmo C1 at the same time while doing Live streaming?
Semi new to your channel and love it. My only negative feedback is that - I felt like you were trying to break up Pam and Jim when she was in art school. Love the tutorials!

I think I heard something similar from DogTimes Productions when talking about Vaxis systems
@@tallguytrav Yup. That's the one! Thanks!
It’s metal you say?? 🤔 Can it handle the ultimate Epic Light Media test?? Who agrees this needs to be thrown from the roof ✋🏼✋🏼
Love you videos. Do you know if the USB-out supports audio?
this is my next project!
thanks!
Are you going to do a review on the dji ronin 4d?
you should try it on SDI, HDMI also has pretty large lag by it own,

buenas, si conecto de la camara al trasmisor por sdi y en receptor al monitor por hdmi sale ? o solo sale hdmi a hdmi y sdi a sdi ? gracias
Nice review. Does this transmit the audio from camera?
Yes, anything HDMI can carry it will carry
Any idea how it compares to the mars 400 S? Really currious!
Is it possible to use two cosmo c1 at the same time ?
So what must I do to have hollyland send me things to test?!
Hi,
If the signal enters in hdmi on the transmitter, can it be recovered in sdi on the receiver, and vice versa?

It's accsoon's cineeye 2 pro, not Hollyland...some of my friends have been using cieneeye 2s pro and they fancy it.

why does your "window" keep shaking ?:D

so this can work for livestreaming ?
Yes
that latency was bad...what am I missing?
You're missing that the video is sponsor piece. Let Epic pay some bills.

Hdmi has delays not sdi
So 400 Mars Pro or C1🤷🏻♂️
