Description

Hello izzytwosheds,

Thanks for this great library, but we are facing some issues with the quality of compressed videos. I have few questions :

1. If video is already compressed and user compress it again, then there is huge quality loss.
2. Videos gets more pixelated when there is effects and transitions in video, Why ?
3. What is the best bitrate for less quality loss.

I am attaching this links and videos are compressed with litr ;

Start with the two linked compressed-video samples and the three questions about recompression, effects, transitions, and bitrate. Reproduce the reported quality loss in LiTr's Android transcoding path; done requires a reproducible, scoped defect or documented guidance for the reported cases.
