Got any questions about the new Blackmagic Studio Camera? Put them below and I'll do my best to answer them ASAP! ⬇️
Does BMSC Plus send 4k through SDI Out?
Hello Alex,
is it true that the camera has no auto focus? Blackmagic says that the camera will be good for sports productions. But without auto focus I would have a big problem with that.
@@maximilianschmidt7432 It has autofocus but it is not continuous autofocus. You basically press and hold the screen on an area each time to trigger the camera to focus. If your subject changes you need to re trigger it. If you're not confident in using manual focus for your sporting event, I would probably recommend you looking at cameras that have continuous autofocus built in instead :) Hope this helps
@@AlexPettitt Thanks, that helps me a lot. 👍
Does talkback work with a 3.5 mm headset?
Thanks for your review. I love your passion for the Blackmagic eco system. They can't be beat on price and functionality which actually works in most cases.
Nice! Thanks for all the great Blackmagic related videos, mate! Truly appreciate them 🙏🏼 These new cameras look solid! I think for a one-man studio setup, it’s really convenient with a flip out screen, so it’s kind of a bummer to have that amazing screen which I would rarely look at. Is the microstudio4k discontinued? What little monitors would you recommend with quality to match for a camera like these?
Hey, yeah I agree with you, a screen that has some move-ability would definitely be nice! In terms of external monitors, I use a lot of BM's Video Assists. I fine them great!
@@AlexPettitt thanks. I had a high end BM video assist for some time. Very nice. But in my closeup environment with a mic close-by, I found the Assist’s fan noise just about a notch too much for my setup. Now I’m just using a big cheap HD-TV. For keeping an eye on the composition, focus, histogram, audio levels and recording status. I’m thinking of getting a smaller portable HDMI monitor though. 12-15” or something.
Great info, thanks. I started working in broadcast TV on a 2 camera Outside Broadcast truck. This was the state of the art gear at the time. Cost hundred of thousands to put together. Now one can put together a 4 camera video recording studio/OB setup for around $10,000.00. Nuts! We live in exciting times. The fixed monitor situation is a bit of a pain in the rear but I am sure it has to do with cost cutting. BMD have been made aware of this from the very start when these designs first came out. Question for you, if program video can be fed back to the screen, that would permit you to use this as a monitor when not used as a camera?
One of the best reviews comparing the two. Thanks!
Glad you liked it Kevin. Thanks for the feedback :)
That's a great presentation straight-to-the-point
Great work, as always!
Fantastic video, very informative and helpful thank you for this. 🙌🏾
GREAT VIDEO as always!
Alex, if you allow me one question please. Can you use the HDMI and the SDI outputs of the Pro model to send the signal of the camera to two different monitors for example?
Thanks in advance
Have a Productive and Healthy Day!
Thank you for the video,! Very deep discussion.
From everything I've heard BMSC is a great studio camera for multicam set ups, but when you wanna use it as a regular "run & gun" camera is where it falls short (on top of it being a MFT mount) and you'd go better with a Sony or equivalent prosumer camcorder
Thank you for the video. There were a lot of helpful tips. Tell me good lenses for this camera, especially when the range of 100-400 is not enough, then what kind of lens should I put for shooting in a large hall? Also, what lenses can be controlled from the tripod handle?
Would you happen to have a speedbooster and ability to test the remote functionality of focus through a mount adapter to an EF lens? The powered zoom options increase 10fold if we can use active adapters...
Super helpful. I'm thinking of investing in the Studio Plus as I already have an ATEM Mini Extreme ISO switcher. I do mainly livestreams and I need to update my cameras. I love that you're using the Sigma 16mm lens with it as that's one of my favorite lenses on my Canon M50 cameras. The Canons are nice but their limitations are really starting to bother me. I subscribed. Keep up the good work.
Hey Jim, Glad it was helpful! If you already have an ATEM Mini Extreme ISO then you'll definitely enjoy these cameras! So many great features when you use them together and I'll have a video coming out with some of my tips for that soon. Let me know if you end up getting one for your setup. Alex
Thank you for this Video. Do you think this camera can be used for Outdoor live captation ?
Hello Alex! Great video! I'm a new subscriber. You got me with the new NAS video (I also just purchased a QNAP) ... and I'm glad to see you use the BMD Studio 4K Pro (just purchased a couple of these myself). QUESTION. You mentioned that you use the Mini Extreme switcher to help you focus. Are you then recording in-camera instead of the switcher? I know the switcher is only HD. How else are you using the switcher at your workstation while shooting? Thanks man!
Alex! Great video!
Question:
Can you use LUTS with the color calibration?
I see no reason why you can’t apply a LUT in camera, and then still make tweaks on the colour cal using ATEM software control :)
So, I'm looking for my next camera to use for aircraft videography. So, outside, on a tripod, fast paced action during airshows, etc. Would you recommend this camera for it? Or is it really a camera that you should only use indoors in a studio?
Excellent video. Do you know if a hdmi extender that supports cec will support the return of camera controls and tally from atem controller to camera? Thank you.
Good video. Can you record BRAW via USB-C while sending out a signal via SDI?
very welcomed video, thank you for great review!
My pleasure! Really glad you liked it Victor
Awesome video review! Can you send video out of the hdmi and the sdi at the same time?
Yes you can. Although know that the HDMI is limited to 1080p
Question : can you get the camera output and control the pro model through HDMI (with an Atem mini), and use the SDI IN to feed it a random SDI source, for example the output of a HDMI to SDI micro converter ? I wonder how the SDI IN can be used in the absence of a « Big Kid » ATEM.
Also, when using SDI IN and OUT with a « big » ATEM, does the HDMI OUT output the program, when the PGM button is pressed ?
Thanks for the in-depth video. What do you think the odds are that there is a Pocket 4K Pro on the horizon?Blackmagic already has the internal ND's and tiltable screen from the 6K Pro. It seems very doable for them to give MFT shooters one last cinema camera.
I was wondering the same thing about the tally masking by the prompter and just figured out a possible DIY solution: You could buy on the cheap a plastic toy periscope, cut the lower part to length and stick it on top of the tally pointing at the subject.
Do you know which lens adapter I would need to put a Canon EF 16-35mm f/4L IS USM Lens on the Studio Camera 4k plus?
Hi Alex,
You mentioned around minute 11:16 that the Studio Camera 4K pro only records 4K, but what if the cameras are connected to an Atem Mini Pro, not even that way could I scale the resolution down to 1080p? I mean, the Atem Mini working as a bridge between the camera and the computer.
Thanks
Hi Alex, great review. One question - how feasible it is to use for outdoor live music events or outdoor live functions at night?
I guess you could add a viewfinder shade or as we do in broadcast TV, fashion one from some cardboard and black gaffa tape...😁
Hi Alex, thank you for your extremely good videos! They have helped me many times when I had to make purchasing decisions. I would like to switch to BMD Studio Pro cameras in my photo and film studio. So far I only have Canon R bodies (R5, R and R6) and only R lenses. Also I was told by BMD that they have no plans to go to R mount or R adapter. Do you have any other information? For me, that's the only reason why I haven't completely switched to cinema cameras. Thank you for your reply and greetings from Germany, sends Dirk :-)
I would also like to see a before amount with the connection that goes into the camera like they do with the broadcast camera so when they connect a B4 lens into the Blackmagic 4K Pro
Hi Alex, thanks for the video. The specs say it has autofocus with compatible lenses. Is this continuous autofocus that tracks your eye/face, and which lenses are supported with autofocus capabilities?
Hi Cheine, it wouldn’t be continuous auto focus as the camera doesn’t currently do that. You’d have to trigger the autofocus by long pressing and holding on the screen or setting it as one of the three function buttons. I hope this helps
Here's a stupid question, do you need to use an ATEM mini to live stream with a Blackmagic Design camera? Say we're just running over a video transmitter like Hollyland Mars 400s, and into a camlink or video capture card on the other side plugged into our computer. Could you use OBS to do all the switching "in house"? I know you would have more functionality probably running through an ATEM, but would that work?
What lenses would you recommend?
Alex man,thanks alot for your videos 🙏🏻
Thanks Nirbhay! Hope you found the video useful! Got lots more tutorials coming in the next few weeks
@@AlexPettitt looking forward to them!👍
I'm shooting n 8-episode sitcom. I currently have a pocket cinema but thinking about purchasing either two Studio Cameras or an additional Pocket cinema. Thoughts?
Question kind of Blackmagic camera Studio Pro 4K what good long-distance zoom lens will be good to use for example at the pastor at 300 feet from you what would be a good lens to get a headshot half shot full shot would it be a good broadcast man's for cheap that can do that far distance to had no breathing
Great vid! Received my first Studio Pro yesterday, I can’t see a practical way to attach a SSD safely - I assume the ‘plug n hang’ method isn’t ideal! Thoughts on this? Also we’re using Samsung T5’s on the 6k’s as they’re usb 3.1 do you know what USB port this one has? 3.1 or 3.2? Thanks!
I've been putting the ssd on top of the hood but we don't use any movements once it's recording so there's no chance it will fall out. I'd suggest taping a ssd/iphone holder to your tripod leg which is what we did for a bmpcc 4k once.
I’m thinking about getting this camera. What lense is being used right now with this video.
Really helpful video as I look to get into professional live streaming so thank you. Just a friendly prod though, watch those "plosives", roll off some bass or edit with a subwoofer.
I want a multiple use....
I'm planning on purchasing 3 studio 4k pro however the 4th camera will be the 12k.
The 12k I'll use to make "musical performance" films that I'll make for Film Festivals.
Will the studio 4k become my camera 2,3 &4 for my indie STUDIO work?
The entire project will always be filmed in my recording studio.
My console is my Tascam model 24.
My Mics ...U47, baby bottle and Shure 55delux.
How does this camera match up together with PTZ's in one live show? Specially the colours?
I’m recording and live streaming a small talk show and will be using a three camera setup, would it make sense to use one Pro-model and two Plus-models?
Another good video, thank you. I think anyone streaming from a large hall, NEEDS the Pro model for XLR and SDI, but if you are wishing 5m of the switcher, the Plus makes some sense.
Yeah exactly Matt! I can see a lot more PRO's being sold that Plus's personally, but I still like that BM brought out a stripped back version for the simple and smaller ATEM Mini setups :)
Very long copper and even fiber optic HDMI cables are pretty cheap nowadays, they can be a viable option for those on a budget.
Can you power the camera off and on remotely through the Ethernet connection?
Great video, think I'm pretty much sold on this for an upgrade of our existing studio space. I'd be really interested to hear/see more about the lighting setup you have in your studio in order to get such a great image from the camera/lens.
Hey Jay, thanks so much for the comment! Yeah the studio cameras are fantastic! Have loved using mine so far, so I’m sure if you do upgrade to them you’ll feel the same! Thanks also for the compliment about the lighting. I’m actually planning to do a bit of a end of the year studio tour video where I cover this… so it’s good to know there’s a request for it ;)
@@AlexPettitt That would be awesome. Subscribed now so will keep a look out for it :-)
I’ve been having some trouble trying to dwindle down the right lens for the black magic. It is for our church live stream service
Hello, have a good time...
I have a Blackmagic Studio Camera 4K pro
and a Canon CN-E18-80mm T4.4 L IS KAS S lens
But the lens is not connected to the camera
Please tell me what conversion you used to connect this lens to the Blackmagic Studio Camera 4K pro? thank you
Good Review... I wish the Plus had at least a XLR mini like the pocket
Audio engineer here. If you move that mic about 6in from your mouth it'll help get rid of those plosives and exhaling noise. Condensers aren't meant to be so close to your mouth, unlike dynamic mics which are supposed to be around 2in away.
Thanks Gabriel! Appreciate it. Will give it a try next time. Can’t wait to move house so I can actually have a studio with lots of sound treatment!
You can put it just above your head too… aim it at an angle towards your mouth and still good audio.
Thanks for the video. I am having a problem getting the Tally together on my cameras. I have two 4k pros running SDI through the ATEM 1 M/E Production Studio 4K. Do I need another device to get the Tally going on the cameras? Thanks for the help!
Hey, if you're running into a 1M/E Prod, you need to make sure that you have 2 SDI cables connected to each camera. One for the OUT (to the ATEM) and one for the IN (from one of the ATEM's AUX's back to the camera). Then set that AUX bus on the ATEM to be program output. You also need to make sure one the camera settings that you have set the correct camera number. I hope this helps!
HELLO can i use a lut with this camera while its in a live streaming set up,if so where do i get luts ,how do i install them
Hey Alex, thanks for the Atem mini videos. I have a question. Can you connect a DSLR to the Atem mini without the need of a laptop, all via WiFi?
Not that I'm aware of (I own an Atem Mini Pro Iso)
i've seen several videos on youtube about this camera.
do you also feel, that it has always a green tint in the skintones?
Did you try the Olympics 40 mm to 150 mm pro lens f2.8
Is there anyway I can connect a battery pack to make this camera mobile?
I have a quick question! I connect my new camera to my ATEM Television studio and it’s not picking up the camera feed! I’ve tried both HDMI and SDI but still not getting a video output… but I can feed when I connect directly on tv, please any advice?.
which lens do u use? Thank u
What long do range lens did you use on that camera that you can control from the camera
Id like to see an SFP port.User interchangeable and you could use RJ45 or Fiber depending on applications, runs or Installs.
What do you think about an external zoom motor to use the zoom demand for a more variaty of lenses? Maybe BM is going to offer this? Any information about that?
I love this idea!
I need a lens for the blackmagic 6k pro, for video in a church, at a distance of 20 meters, what lens do you recommend, please 🙏
What's the specification of lens used
Do a video comparing the bmpcc 4k and studio cam
How is rolling shutter? I'm streaming motorsports races
If you were doing a livestream for a church service using an unmanned camera and the choice of cameras was between the BM Studio Camera 4k Pro and the BM Pocket Cinema Camera 4k, which would you choose and why ?
I’d go for the Studio Camera, mainly as you’re getting a large screen, tally lights, full size XLR inputs, 12G SDI, streaming etc all for the same price as a pocket. If you’re not going to be using the camera for run and gun stuff outside of the church then Studio camera wins it every time IMO :)
Any thoughts on how one could power this on the go using some sort of adapter to a battery?
The barrel power connector works with 12-18V so you can use a V-Mount battery with the appropriate cable. Or probably even a car jump starter that has a sufficiently-large sealed lead acid battery in it. That'd be a simple cig lighter to 5.5mm DC cable.
Alex, Can you use the HollyLand 4k Wireless with the BMD Studio Camera 4k Pro?
Hey Steven, yes you can :) Either via HDMI or SDI. I hope this helps
Alex -
I have been searching around quite a bit and have it not yet found a solution to my situation. In short, I want to connect my ATM Mini Extreme Iso switcher to one of the new black magic 4K plus cameras via HDMI. However the problem is in our permanent install situation, I need a cabling distance of 200'.
I have yet to get a definitive answer from anyone on whether this is possible with HDMI, including the option of some of the optical and or Active HDMI cables, or even an HDMI over cat six conversion set up.
Obviously I want to maintain the two way communication option to be able to control the camera from the switcher.
Any guidance here is greatly appreciated
Best Regards, Tim
what lends do you use on this camera?
I would like to see a a prores D and another recording into that camera that gives you the option to use I would like to see them come out with their own zoom lens like a zoom lens that goes 10 mm to to 400 MM with a doubler with 114 mm front filter thread
Can the ethernet port be used via NDI?
Where are you recording your audio to? It looks like you're using the 3.5mm jack to your ATEM mic input. Where do you plug in your USB for it?
I have the NT-USB as well and I tried out my brand new ATEM and my first attempt I got a lot of loud electronic screeching sounds.
I came back a few hours later to diagnose and it went away. Not sure your recommendations for how you setup your mic in this studio. Hopefully you have a video on that.
ruclips.net/video/Ui30by2Tplk/видео.html
I'm still holding/hopeing for a screenless PTZ camera from Blackmagic Design based on the Studio Camera 4K Pro, to connect with my current Blackmagic ATEM Extreme ISO ( which I am loving using ).
I know right! And all in one PTZ would be amazing! No idea if BM would ever do something like that, but a lot of people are expecting them to refresh their Micro Camera line soo, which are really easy to mount to a PTZ head :) Fingers crossed
Can you use a cloudlifter when directly plugging an XLR mic to the camera?
I see no reason why not as the camera can provide phantom power. Although the pre-amps in the camera are incredibly clean, so might not even need a cloudlifter :)
Alex what are those rgb lights behind you ?
What record settings (frame rate and quality level) are you using with your Sandisk Extremes?
I’m recording at Hyperdeck High at 1080 50fps. I’m recording the program + all 8 ISO’s from my ATEM Mini to a SanDisk Extreme without issue :) When recording direct from camera I’m using the same drive and recording at BRAW 8:1 at full Ultra HD res
Hi, would you happen to have any recommended remote heads to control pan & tilt via control room?
Also, I understand it records RAW ONLY internally but what if I'm trying to send signal to my ATEM switcher can I manipulate it to ProRes through the SDI output? Thanks!
Hey Rosalia, the best one I’ve seen is the DJI RS2 with a Middle Things controller. This gives full control of Pan & Tilt & all camera controls.
The SDI output is uncompressed, so if you attach a recorder that records in ProRes via SDI then you can record to that. For example, a Hyperdeck Mini will record the SDI output from the camera In either Pro Res or H.264 :)
Thank you for the comprehensive video. I was considering this camera(s), but your video was so comprehensive and straightforward that it became clear that this was not the camera I need/want. Not on you… BMD missed the mark yet again. They are becoming the new Apple (take things 80% of the way and then inexplicably stop…..). So disappointing. Thanks for the great video Alex.
Does Tally lights and atem control work when hooked up via SDI?
It does, you just need two SDIs per camera 👍
I never really considered these useful but I think they could be great for pod casts
I would love to see that prores Cinema D and another
I cant get the Talley light or any controls to work on the atem. Any advice. Running only SDI
If you’re running SDI, do you have a return SDI feed going to the camera?
Question about talkback via sdi.
How do you setup it, with extreme iso ? If u have like 3 pro cams?
Right now, talkback is not supported by the ATEM Mini range, you need to have an SDI based ATEM that has both SDI in and SDI out for return (as the talkback uses SDI channel 15 & 16 in the return feed). Hope this helps
You need is Atem production studio or Atem television studio series mixer for it
I use 50m (160ft) optical HDMI cables all the time with no problem. Not as sturdy as SDI though.
I want to buy 2 for a tv studio
I have just bought one and am awaiting delivery in the next few weeks. I understand it does not come with an MFT lens. what lens are you using on the camera in your studio?
Hi Leslie, I use a Sigma lens. You can find it in my kit list here: kit.co/alexpettitt/my-camera-setup
What about a wireless transmitter that transmit video and audio to a switcher instead of using cables do you know of any affordable cheap video transmitter for that
Check out Hollyland or Teradek for that :) Both work well :) I have a video on the Hollyland Mars transmitters on my channel
The Pro surely great for realtime virtual production.
Good job. You made our choice easier between Sony and bmd cam.
Really glad to hear this! Now the big question is... Plus or Pro? ;)
Anybody else scream when he let that hard drive just hang? Great review btw.
Would tally and talkback work on the plus if I use a Hollyland Wireless Video Transmitter? Thank you!
I’m afraid not. The Hollyland wireless transmitters only work one way, it does not send any information back from the switcher to the camera. So tally info etc won’t work
@@AlexPettitt Ah, okay. Thank you for your feedback!
Same sensor as the BMPCC 4K, but I got trapped by the Studio not doing ProRes - I had a very tight workflow built around ProRes and didn't do my homework/testing on the Studio 4K+ before using it on a job. It caused a lot of issues in post...my own fault, but beware.
There's also no easy way to rig accessories on the Studio models, if you need to mount a little mic you may find yourself slinging it below a 15mm rod, under the lens.
The ethernet port can carry video signal correct? Is there a way to encode this signal so it can be NDI? That way we can have one ethernet cable for power and NDI feed..
Unfortunately not. For now, NDI is not incorporated into BM products
@@AlexPettitt I know NDI is not incorporated into the camera itself. My question is if there is a way to encode the video signal into NDI utilizing the Ethernet port, JUST like you would with the SDI or HDMI...... ?
hey dude did you run into the same problem I have my microphones XLR connector to my Blackmagic Studio Camera and work perfect when recording locally but the moment I try to recored on ATEM Mini viva usbc I have no audio
No, never run into this issue. Do you have them turned on in the ATEM Software Control? You need to enable the audio for that camera so that it is turned on in the ATEM :)
On your opinion, do you think that this cameras will work well on a church to record and stream the service. Thanks for this video.
Absolutely Iglesia, I think they're perfect for these type of environments, especially if you're looking to incorporate them as part of a Blackmagic ATEM setup :)
It’s the lens you have to think about. Having a good zoom (and focus) on a high end camcorder can be very helpful….. but the Studio camera Pro would probably be cheaper. For a church, get the Pro (not Plus) to make use of the SDI for long cable run, and XLR for audio from a PA desk. I’m thinking about the same thing now, as our SDI camcorder needs replacing.
can i use it on a 24/7 operation livestream?
Yes you can. I have run Blackmagic cameras on continuously for months :)
11:10 saved me. I assumed it recorded 1080P as well :(
Can you please ask Black Magic to create an ATEM Pro NDI + POE switcher? Would be incredible to run a few of these cameras directly to a switcher via only 1 ethernet cable with audio+video+poe+tally etc
I have to second this request. I would love to see an ATEM which supports controlling multiple cameras via ethernet.
Wouldn't that be lovely! Personally I don't ever see them incorporating NDI into ATEM, but I do feel like they will bring their own similar standard at some point that would enable this kind of operations. Fingers crossed!
@@AlexPettitt to be more precise, I don't see NewTek licensing NDI to BlackMagic...
considering Audinate is coming with Dante for video however, I could see this happening
Yes, "World's Best Camera Audio" picks up the camera fan noise just fine! 😞
There are VERY limited applications for on-camera microphones.
Two that I can think of are: B-roll shots of breaking waves at the seashore,
or B-roll shots of motor races (laps, pit activity, etc.)
In both of those cases, the audio is there for authenticity, not for dialog, etc.
and the sounds you are recording (surf, racecars) is significantly above the fan noise "floor".
I might be wrong, but if I remember correctly the comment was referring to the XLR inputs on the camera rather than the on board mics?
What is your lens on this video? Thank you
My full kit list can be found in the description for each video. This one was shot with my Sigma 16mm lens :)
