Choosing the Right Color Profile (Mac Shared Screen)

Photo Moment - April 20, 2021

Does your Mac display look… wrong… on your ATEM Mini? There's a good reason for this. You need to choose the right color profile!!

Need an ATEM Mini?

What this tip is about…

When you connect your Mac (and possibly a PC… sorry, I don't know!) to your ATEM Mini, ATEM Mini Pro, ATEM Mini Pro ISO, ATEM Mini Extreme, or ATEM Mini Extreme ISO — the colors will NOT look right!

Now, to be honest, most folks will never notice. But, if the screen looks off to you, and you do want things to look as accurate as possible — especially if you're doing software demos through your ATEM! — then, you will want to choose the right profile.

Which profile is it? That's “easy”… it's SMPTE RP 431-2-2007 DCI (P3) 😂 — Just remember that it starts whit “SMPTE” and ends with “P3,” and you'll be good to go!

While changing to this Color Profile will make a minor improvement, it doesn't fix the source of the problem. The issue is that the USB-C output is exporting a compressed (15-235 instead of 0-255) range. That means that blacks and whites are being "clipped" and there simply is no way around it.

If you're using OBS you can switch to Rec 709 and get the full range. In apps (Zoom and FaceTime specifically) there's no fix.

My solution was to purchase a Cam Link and use the HDMI output via Cam Link into Zoom. No more compression issue.
Side note - I also tried a cheapo $18 HDMI-USB capture device from Amazon and it looked even worse than the ATEM input. The Cam Link 4K looks outstanding though and works perfectly with Mac displays and Apple TVs.
So, you’re talking about a different issue. You’re 100% correct in USB vs HDMI output. However this is about bringing a Mac screen into the ATEM, i.e. for a software demo.
@PhotoJoseph No, that's exactly what I'm talking about. The entire issue is created by the way the ATEM mini handles webcam out via USB-C. When using the ATEM as a source for an app like Zoom or FaceTime (with Mac display on HDMI 1, for example) the resulting stream via USB-C webcam output looks miserable. The main HDMI looks fine though. The output of the USB-C is a compressed version that clips roughly 15-20 points on the far end of the levels, resulting in an overly contrasty image.
By skipping the USB-C webcam output on the ATEM and instead using HDMI OUT -> StreamDeck 4K video capture card, the result is an uncompressed stream with no clipping. I've been constantly complaining to BlackMagic about how they're compressing the MJPEG output of the USB-C stream, but crickets.
Hey Travis. The compression they are adding is likely in hardware, so unfixable. But, who knows.

As far as the color — I still maintain that we are talking about different things. If you plug a Mac's HDMI output into an ATEM, and a monitor into the ATEM's Output (forget USB, we're not touching it), and mirror your screen in the Mac — the output from the ATEM will look different until you set the color profile as directed in this video. That's what this video is about.
The original profile is darker because macOS is choosing the legacy BT.709 camera encoding OOTF (the inverse of which is Gamma 1.961). The "BT.709" option in macOS's display settings also does this. In the world of television, encoding and decoding gammas are often different so as to change contrast and compensate for viewing environment differences.

A modern calibrated TV is Gamma 2.4 (or 2.2 for a bright room, or due to backlight bleed) and computers are close to 2.2 but not exactly (because sRGB and ICC viewing environment management is a mess.)

The sRGB profile would be the easy harmless alternative, as it’s closer to (though not exactly) Gamma 2.2, which might better reflect how many consumers will view the content (for instance if you're making YouTube videos). A lot of web browsers also show video as sRGB.

Worth mentioning that QuickTime/Safari decode video tagged as BT.709 with Gamma 1.961 (inverse camera gamma) which would brighten that darkened content back up again. It’s likely to be fixed in future versions of macOS to decode as Gamma 2.4.

The old fashioned 1980s chain used to be: Camera encodes as roughly 1.961, then CRT decodes as roughly 2.4. These days in video production we mostly only care about the display part, and ignore the camera part. I'm not sure why macOS still cares about it so much. Actual cameras meanwhile are all over the place, mostly ignoring the old encoding guideline and instead using the manufacturer's custom tone curve so that it looks good on a 2.4 display while also having decent dynamic range.

In the event you're recording your screen virtually such as with OBS, keep in mind modern Macs are P3 color with sRGB tone (Apple's so called Display P3) so it might be best to use a LUT in OBS so you can view the right thing (Display P3) while also recording the right thing (BT.709/Gamma2.2)
We are waiting for the next Atem Tip 😃
"Conveniently named..." LOL (& Great tip! - added to my ATEM playlist)
hehe sweet!
Hey Photo Joseph! Thanks again for your awesome tips! I would love to see one about camera control via ATEM software control, particularly regarding zooming in and out on the Blackmagic pocket cinema cameras. What kind of lenses work for that etc. There seems to be very little info about it out there..
I'm going to work on that today, as I just happen to have a BMPCC and a motorized zoom lens in house right now!
@PhotoJoseph That's amazing, thank you so much!! Really appreciate it. Can't wait to watch it
thanks again for doing this!
Sure thing, thanks for watching!
Tip on Connecting the Atem to a network (with or without internet) and controlling it with multiple devices. Will really appreciate on showing the router configurations for a reliable wireless connection. Thanks.
You don't need any special configuration to have multiple computers talking to the ATEM. Any number can be connected at once. It will execute whatever last command it got; no matter where it came from. As to wireless — don't do it. The ATEMs are very finicky on their network connection, and any little glitch will make it drop the connection to the software, and take several seconds to reconnect. I've been using ATEMs for a long time. Don't go wireless. Even if you use an iPad to control it, you'll want an ethernet connection on your iPad.
@PhotoJoseph Thanks Man! :)
Sure thing! Although the fact that you asked the question does make me think it'd be a good mini tip!
Dear Joseph,
Thanks for your time in advance.

I have 1 Pocket 6K and 1 Pocket 6K Pro and 1 Atem mini extreme iso. I do livestreams directly from the ATEM via the Ethernet connector.
All works fine.

my question is:
When the Pocket’s are connected via HDMI to the atem, the camera’s are on the BRAW setting.
Assuming that iso/exposure etc settings are properly dialed in, What/Which LUT setting on the camera’s is the appropriate one when you want to give the viewers at home a descend, graded/broadcast-ish image ?

Hope to hear from you, and many thanks!! 👍
I don't own those cameras, but in general if the camera has a Rec709, or "like 709" LUT, then that'd be the most basic, clean, broadcast-standard LUT.
Awesome tip - many thanks!!!
You're welcome!
Thanks, Joseph. I've been looking for tip like this without realizing I was looking for a tip like this.
haha awesome
Thank you for the tip Joseph!! The other problem with color profiles comes when you want to get the usb ATEM output on your computer to send via StreamYard or OBS, it's also darker, but you can't change the ATEM profile obviously... What you recommend to do? The ATEM USB-output signal its also darker and saturate 😔
I think that's a byproduct of the compression happening over USB. To avoid it entirely, use the HDMI output and get a dedicated HDMI to USB converter.
Do you also have an idea why light greys in UIs from some devices (Surface laptop 3:2 and MacBook Pro) appear as white when they're plugged into Atem Mini.
I saw this behaviour when I record with OBS and it's on the record file.
Did you try changing the profile as discussed in this video?
I’ve had the ATEM Mini for like 4 days now, I couldn’t’ figure out why it was darker, now I know.. THANK YOU!
Right on! Yeah, this makes a big difference!
When I connect my Apple TV 4K to one of the ATEM Mini inputs, it also looks a little darker than it should with darker scenes... is there a fix for that too?
No, however the new Apple TV 4K will have that screen calibration feature which might help!
Love your info. Consider doing this: I want to record a Zoom call on an ATEM. The entire Zoom call, with everyone on it. But Zoom doesn't see the ATEM as a monitor. I tried running Zoom through an external monitor and then, via HDMI out, to the ATEM, but I see only snow, no image. Would like to know if this is possible. Thanks.
So you’re connecting the HDMI out of your computer to an input on the ATEM, right? Watch the previous tip, 008, on how to do that. The rest will fall into place.
Just joined the Atem family and you are a lifesaver!!!
Right on, welcome to the family, Nathan!
Please how can fix Audio delay or sync on Atem mini and what cause that product ?
Here's the video you want: https://youtu.be/H07ZW72CSD0
@PhotoJoseph ok thank you I will try and give you feedback
Really mini that tip, but really helpful! I’ll check that out when I start up my ATEM Mini tomorrow.
it makes a difference, for sure!
@PhotoJoseph I tried it – and it makes a huge difference! I almost feel like having to re-record some of my videos from the last two weeks again, in particular those where I had photos on my lecture slides. Thank you for pointing this out!
You are very welcome, (and I'm sorry if you have to re-record!)
Turbo Top Tip!
hehe emphasis on TURBO, yeah? 😂
I always wondered why the output was darker! Thanks Joseph!
Happy to help!
What is the best way to get a mixer output into the ATEM iso so it can be recorded with all the other video inputs?
Into one of the Mic inputs; just be sure to set it to line level (in the ATEM software)
Also check your mixer audio output, which is probably balanced. The Mini Pro is unbalanced, so you will need to make that conversion. Probably second nature to the experts, but it kept us confused for a couple weeks.
I’ve tried three ways coming from a peavy Aureus 28, all going into one on the Mike inputs. I’ve used the headphone out on the mixer with stereo cable, and of course loose the monitoring. I’ve used what is called a control room out and adapt RCA to 3.5 stereo in, and third I took two linked bus outputs into a audio interface and use TRS 1/4 headphones out into 3.5 TRS on ATEM. The headphone outputs are unbalanced but the linked bus XLRs aren’t. What is the proper way to unbalance them? Thanks
@Dennis 6749 Mathews Again, I am far from an expert, but have successfully set up an ATEM Mini Pro to livestream at our church with our sound board. Hopefully someone else will weigh in here. If you don't need the control room outputs for anything else, I think that is your simplest approach. The RCAs are unbalanced and according to 30 seconds of Peavy video I found, they mirror your Left and Right Main Outs. From your original post, I am not clear whether that worked for you. That does preserve your headphone jack for monitoring. If you need the RCAs for something else, Google "balanced output to unbalanced input" and you can find pin-out information. That will require some soldering to wire XLR output connectors to an input plug for the ATEM. There are probably more proper ways to do that transition, but if your run from the mixer to the ATEM is relatively short, you shouldn't pick up any noise problems. I imagine some configuring will be needed in your mixer to get the sends you want to a pair of XLR outs. Hopefully that helps.
