Quoted from Sonny_Jim:EDIT: So I started checking other frames, it appears that the above rule holds true for frames:
1, 39, 188, 257, 295, 444, 513, 551, 700, 769, 807, 956, 1025, 1063 and 1212
What's so special about the numbers 38, 69 and 149?
Total size of frames? (i.e. Frames 1-38, then so on..) Or playback speed?
