Frame ordering #398

Closed kp-121 closed 2 years ago

kp-121 commented 2 years ago

I've changed how we name the extracted frames, but the old timestamp ordering should've worked. I'm going to leave this open until we either find out why the ordering is off or we don't see the problem any more.

OK, after doing another REALLY long one the first pair (frames 1&2) seem wrong (maybe replicated frames). After that, they seem reasonable.

It's most likely replicated frames caused by converting 1-based to 0-based and back again. This helps a lot!
