I see. You're right, then this technique is probably a dead-end...

More generally, which is the recommanded way to cut a video with a specific starting point and specific length, with minimal re-encoding?
Millions of hours of CPU-time are probably wasted to reencode already-perfectly-encoded content, just for cutting ;)

Are there already promising dev attempts in the direction of a feature able to cut with minimal re-encoding?
