Question / Help Colors

[ttiasas]

Hello,

I use ezcap 261m and connect DSLR to Macbook and OBS to stream.

I attached screen > one is from live in facebook with OBS and one is same video at the same time I record with DSLR.

Why colors is so different? I use standart OSB settings and didnt change anything. It can be OBS problem?

Original DSLR record:

Live from facebook:

I don't see any mistakes in your configuration.

If you don't like what Facebook's reencoding does to your colors you can try and compensate by adding a color correction filter to your image when you stream.

Right-click your video source in OBS and choose "filters" from the drop-down, then add a "color correction" filter. You can use this to make adjustments so that the final image when you stream looks more like your source.

Might be long shot, but maybe check what Facebook's own advisory with regards to YUV mode is. Partial range can lead to crushed blacks and maybe Facebook expects a full color input except of partial.

However I noticed that even with 709/Full range the output is darker or more vibrant than the source. Haven't found the reason yet though.

Facebook is primarily viewed on browsers and most browsers expect Partial.
