Hi folks, apologies in advance for ANOTHER thread asking about tags/gamma/rec 709a etc
I'm hoping this is just a case of getting confirmation i'm set up correctly as for the most part everything is doing what I would expect.
So the setup I want to check consists of:
1. a MacBook Pro M3 Max with the display set to HDTV (709 - 1886)
2. a portable Rec709 monitor connected via an Ultra studio 3G monitor
3. Resolve set to use Mac display colour profiles for viewers
4. My timeline set to a Rec709 a colour space
With the above set this way my Resolve monitors match my external display, so I think I can safely say this part of my setup is golden, right?
Now I would like to export some sequences that need to be suitable for both broadcast and web, so I'm using tags to set my deliverables correctly. The settings are as follows:
1. The broadcast deliverable is encoded as ProRes 422HQ with a colour space tag of Rec709 and a gamma tag of 2.4
2. The web deliverable is encoded as H265 with a colour space tag of Rec709 and a gamma tag of 2.2
Once the above files are exported I can re-import them into resolve and everything looks the same and matches my sequence, so as far as I am concerned the file itself is encoded correctly
So the final part of the puzzle is the colour space and gamma tags which display as follows:
1. The broadcast deliverable has 1:2:1 tags and looks too dark when played in QT player
2. The web deliverable has 1:4:1 tags and looks exactly the same as what I see in Resolve when played in QT player.
So my question is, is the above behaviour as expected and am I setting the correct tags? I'd hate to think I'm doing something stupid that is messing up my deliverables at the final hurdle. As an additional (possibly stupid) extra question; do I even need to set gamma tags for the broadcast deliverables, or is this kind of meta data only really important for web based delivery?
Cheers
