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 ;
