Interlacing misaligned when capturing from old visit tape

[animatorgeek]

I finally got around to digitizing my old home movies, which are on vhs tape. I'm capturing the video just fine but it's ending up with a problem with the interlacing. Even on shots with no movement, it looks like the lines are misaligned. It looks like something like this is happening:

ooooooooooo
  ooooooooooo
ooooooooooo
  ooooooooooo
ooooooooooo
  ooooooooooo
ooooooooooo
  ooooooooooo

I can't seem to find any tutorials or guides about how to deal with that problem, but I figure there's gotta be a filter that will fix it. Can anyone point me in the right direction? Even a clue as to what this problem is called would really help.

In AviSynth something like:

AssumeTFF()
SeparateFields()
evn=SelectEven().Crop(2,0,-0,-0).AddBorders(0,0,2,0)
odd=SelectOdd()
Interleave(evn,odd)
Weave()

Change the crop/addborders amount as necessary.

Hard to tell without a sample, but your problem may have been a form of flagging or tearing, and that would likely be because you captured without a TBC that does line correction.

If you don't want to get a TBC, or don't want to capture again, or don't have the tape(s) anymore, then Jagabo's solution should easily correct it if the pattern is consistent.
