Color distortion in compositor and render  


Topic starter

Hi. My problem is:
With every video i tried i have color distortion. This affects the editing stage and rendering result.
Here is how it looks:
Video in player vs Cinelerra:

Better to open links in Firefox, because Chrome based browser forces srgb color profile.

Unfortunately CinGG does not have a global Color Management. For some hints try to read the manual in 17.3:

Here is an attempt (incomplete and probably with errors) to understand how CinGG works with colors:

Oh, thanks @andreapaz, i opened the first link you specified, saw a picture with the color settings of the composer, and now I don't understand how I didn't notice this in the settings of the program before.
I changed JPEG to MPEG and the color became almost exactly the same as in the player. And It suits me, thank you for the tip! 👍


this may be related to the fact that Cinelerra displays the colors correctly (0-255) , but all players and also Firefox does the typical clipping for PC playback (16-235).

I am not sure yet how to set Cinelerra, maybe other users can say more about it.

The only thing that is certain is that there are different color spaces for different reproduction systems. These are called, for example: "Studio-RGB or  Computer-RGB".



Hallo, unfortunately I do not understand enough about color management. Also the hints from andreapaz overwhelm me.
Earlier I had learned with "Vegas Pro" that this software displays the colors, i.e. the pixels exactly as they are. This was very good, but had the disadvantage that Vegas did not easily show the picture as a media player on a PC will show it later. There was a plugin for that. With that, you could choose to see the true colors, or have the higher contrast view that typical media players show.
So my question is: How does Cinelerra display the colors? 0-255 or, as it is common on PC: 16-235? Does anyone of you know?



Ah, I think I understand. When I choose in the Settings > Preferences > Appearance > Color: YUV color range: MPEG, then CIN GG will display the video as a media player on a PC will do later, namely (16-235).

If that's true, then I've taken a big step forward.

Many thanks
