There is clearly a frame missing as the ball is on its downward path, then it skips back a frame...and the frames on either side of the skip-back are identical to each other as well.

I've seen this in a couple of tapes. This one is really bad, but I happened to capture it a couple of different times and only one capture shows the issue, so it's a capture problem not a tape problem.

What's causing it? Do I have to go frame-by-frame through every capture to make sure it doesn't occur? This didn't start until about six minutes in, and it's now happened several times in a mere couple of seconds.

Can anyone answer this?

We need to know everything: hardware workflow chain, tape source information.

Philips VR 1000 -> Panasonic ES10 -> TBC 1000 -> USB Live2. I also have a Panasonic NV-HS1000 and a JVC SR-S388E, and the issue doesn't occur at that time on that tape with either of those captures (JVC through the ES10, Panasonic without).

It's...a tape. Quite a few tapes by the look of it. They're from a box of tapes, they're all older than I am...not sure what you want from that side of things.

Gone through and checked my notes and one of the problem tapes was captured with the JVC unit, so it's presumably not a player issue.

Could it just be low drive speed/capacity and dropped frames? The hard drive (laptop C: drive) and capture device are the only two things all the problem tapes have in common. Seen zero issues on the one tape I've worked on thus far that was capture to a RAID.
