huge color-gamma shifts between programs and players
on Sep 19, 2012 at 10:52:35 am

I use an 8core macpro with osx 10.7.4
with a gt120 + gtx285 gpu configuration
I mainly edit on Avid and grade on Resolve
when I bring dnx Resolve renders back to avid(tried every dnx option), colors are washed out
when I render a prores mov, in finder preview it plays brighter, in qt player brighter and with washed out colors and in vlc player it plays high contrast with crushed blacks
in After Effects washed out again but less than with the players
the only combination I tried that keeps colors the same is uncompressed qt render and import in After Effects
but AE render is again different in every player
I am grading a music video here, client likes the look inside resolve and I cannot find a way to show him the same in a player
I know I cannot trust my computer display for color but shouldn't I be able to see the same colors at least in the same monitor?
I am talking about huge differences here
it's a high saturated warm summer look and it plays very greenish and washed out
please share some info-help, this thing is driving me crazy!

Sounds like you are set up with data levels.
Avid is not working internally in RGB as Resolve do, and output only 16-235 through Mojo DX.

is there a way to render 16-235 from davinci?
and what about the players, is there any solution to make them all match?

You would be a Millionaire if you could find a solution for that.
Basically you need to think of yourself as a chef in a fine restaurant.
If you serve the best steak to a vegan, they will not appreciate it.
There is nothing that works all the time everywhere.
You need to talk to your client and find a common ground where to judge things.
It will never look as good as it looks on your hopefully calibrated screen.
But that should not be your problem.
I suggest you find a way how to talk to your editing application if you really need to finish there.
Aside from Smoke, most of them come short when its delivery time.

Hey Sascha,

do you currently use Smoke with DaVinci? How do you circumvent the video cards incompatibility issue if you're using one Mac?

Hi, Vagelis.

ProRes and MXF is ordinary YUV formats. For finishing in Avid or Smoke, render full range.

When importing full range data to Avid you can choose "import RGB" - it will remap to 16-235.
When you export, export to RGB and it will remap back. This is ok, and gives you no quality loss.

As long as you monitor video levels in Resolve, place the MXF-files in the the avid media folders and drop the database file in your bin - you will be good to go. And, your scopes will read 16-235. Its a default remap as Avid does not work RGB internally.

If you want to work RGB all the way through AVID you need to set up your monitor to show RGB (not 709) and buy a Avid Nitris. I cant see the point and know noone that benefit from doing that.
