Strange interlacing?
I recently shot a video production, and recorded the feed using Wirecast.
The recorded feed seems to have some strange interlacing problem.
Clip: https://www.youtube.com/watch?v=4g_QssGVm0wIt looks like strange horizontal lines, or a horizontal shift.
The lines are much thicker than usual interlacing.I tried fixing the footage using a de-interlacing filter in FCP. But it didn’t change anything.
Does anyone know what caused these lines, and how I can get rid of them?
Thanks.

The “zipper” effect is often caused by reversed field order. Another way of describing the problem is that somewhere in the early production, recording, or post-production phase, interlaced fields were not properly treated. Where in your production chain could this occur? If it happened at the event and is recorded that way, there may be nothing you can do to help it.

That’s wierd-
Tryed SHIFT-fields?

Yeah. I tried field shift, and I tried applying a de-interlace filter.
They did not change anything.
I am not sure that this was a camera problem, because I recorded the feed in several different methods. Only a recording through a “Wirecast” software showed this problem. -
What i see is video scaled without de-interlacing, and without software that knows the source was interlaced.
