How to remove banding in FFmpeg timelapse videos?
I have tried different ffmpeg filters but none did work: deflicker for example is made specifically to remove frame-by-frame luminance changes (e.g., what happens in timelapse videos) but not to fix the banding that I see due to using a shutter speed not in sync with the frequency of the AC feeding the light bulb.
How to ignore errors in FFmpeg video decoding?
Set QP offset between P and B frames. Set error detection flags. ignore decoding errors, and continue decoding.

Why does my video flicker with motion blur?
Motion blur is something that is not easy to capture. If you are shooting for motion blur and you’re having a camera that can shoot at 6 fps or more, and with it, you need a faster shutter speed to take the perfect shot with motion blur. If not, then your video can produce an unwanted flicker.
