Hi ALL!<br>
I don't know if it can help.<br>
An old project of mine uses footage by old NIKON D90 photocamera.
This camera record video to 720p 16/9 yuvj422p, pc (jpeg), bt470bg
(MJPG) in a AVI container. I would like to point out that my Laptop
monitor is calibrated to sRGB with an external Probe.<br>
<br>
For the Edit in Cinelerra-GG the Settings/Preferences/Appearance
was:<br>
Color:<br>
- YUV color space: BT709<br>
- YUV color range: JPEG (0-255)<br>
<br>
and the Settings/Format was: 1280x720 (720p) HD @24fps 16/9 yuva420p<br>
- Color Model: YUVA-8bit<br>
<br>
The Rendering by Cinelerra-GG were two, using MP4 and WEBM settings;
I manually set some value for "color_primaries=bt709",
"color_trc=bt709", "color_range=mpeg", "colorspace=bt709",
"pixel_format=yuv420p".<br>
Below the settings for the the two output:<br>

The ffprobe command says that renderings are: yuv420p, tv (mpeg;
range=16-235), bt709.<br>
