Hi,

 

I noticed that transcoding has some troubles with the red parts in a movie. In the original video it's all nice and clean but when I transcode a movie (for baking in subs) I see strange bars appearing like this:

The original movie doesn't have problems with red colors. There are no issues with other colors, only red.

 

I already lowered the H264 encoding CRF but that didn't made any difference.

Are there other users who experience the same and is there a solution to fix this?

 

Thanks!
