Gamma space issue when rendering to Motion Jpeg A MOV
Hello, I am editing a 5K R3D project.
When I render to Motion Jpeg A, and playback through Quicktime, the black level appears much higher. I.e. the shadows are grey.
The gamma shift is also present when viewing the file on VLC player.
What’s the deal? I need to deliver to a film festival asap.

It’s just the player interpreting your video as Studio RGB. Drop the rendered file back onto the Vegas Pro timeline and compare it to the original footage. I’ll bet it looks exactly like the original in Vegas Pro.
The question is what will the film festival use to view it? If you think they will be using a computer with QuickTime Player then you should drop the Sony Levels filter with the Studio RGB to Computer RGB preset onto the Master Video Bus to expand the levels out to Computer RGB.

I found a post on another forum that fixed it. Very interesting:
“David, I think you have problem with nVidia card changing video output color to values 16-235. You can fix it in one minute.
1. Go to Control panel and open NVIDIA Control panel
2. Find Adjust video color settings, and under 2. How do you make color adjustments? change to the option With the NVIDIA settings
3. In the Advanced tab change from Limited (16-235) to the Full (0-255). When you change the setting you can see how the color is changed in the VLC or QT player.”
