I gonna try to describe my problem the best i can. I have two lists, one with audio frames and other with color frames (not relevant). Both of them have timestamps, they were captured at the same moment but at different instants. So, i have like this:

index  COLOR  AUDIO
0      841    846
1      873    897
2      905    948
3      940    1000

the frames start at high numbers because they were captured and then trimmed to specific parts, but im shot, frame 0 is synced with only 5ms apart(timestamp in ms).

On every case i have, the audio frames count is less than the color count. I need to make them have the same count. The stating frames may be color>audio, color
