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!

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.
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 other issue is about different "range" used by ATEM usb output (full) vs hdmi output (partial)
obs uses "partial range" by default which is a mismatch with ATEM usb connection, in that case, manually change the range setting inside obs to fix that
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)
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 saw this behaviour when I record with OBS and it's on the record file.
