video bitrate

[zhouzhenneng]

When I used the transparent-background tool to process a green screen video, the source video had the following properties:

•	Duration: 00:00:14.85
•	Start: 0.000000
•	Bitrate: 8768 kb/s

However, the resulting output video had these properties:

•	Duration: 00:00:14.85
•	Start: 0.000000
•	Bitrate: 3353 kb/s

As you can see, the bitrate of the output video has been significantly reduced, leading to a decrease in video quality. How can I set a higher bitrate or maintain the original bitrate during processing?

Hi @zhouzhenneng, I'll check if I can do for the bitrate problem in the next release. Sadly, I have no room for the update right now.

Hi, @zhouzhenneng, I changed the bitrate option in opencv videowriter, but this will not guarantee 100% identical bitrate as the input. If you still need the bitrate to be preserved, please save video as images and process each frame, then merge them into video format.
