Comment 3 for bug 610295

Personally, I still have a gut feeling that there is a general problem with DV camera footage on Linux which results in the field order being processed the wrong way round. See my comment on this other bug (https://bugs.launchpad.net/openshot/+bug/508334/comments/1)
Looking at your clip, I would guess that MLT is processing the video with the wrong field order, and those wavy lines are interpolation to smooth out the interlacing. But because this the field order is wrong the interlacing is more extreme.
But I don't know much about this. I just thought I would add a note in-case it is of use, but it may well not be.
