I am using blender 2.8, system Ubuntu
Here is the video codec of source file H264, MPEG-4 AVC
Frame rate 24
In blender, I set the output as
File format FFmpeg video
Encoding Container MPEG-4
Video codec H.264
Output Quality: High Quality
Why the video gets faded, or a dark shadow is formed after rendering?
Original video screenshot (screencast using Kazam):

I also tried many other settings like AVI, but all are giving the same results.
