Weird interlacing - please help

[fberreth]

Hello,

I am capturing a PAL movie which is mostly frame based. However, some editing must have been done and a part of the movie has a weird field order. It goes like this:

field 1,3 form a frame. Field 2,4 form a frame etc.

So when you watch the fields (SeparateFields) as a movie you see a person moving jumping backwards every couple fields.

Is there a de-interlacing filter that I can use to put those fields properly together again? Or can I make a script that would do that? I am not such an AVISynth wizard ...

Thanks,
Frank.

Sorry, the field order was wrong.

It's like
0,3
2,5
4,7
6,9
etc.

I discovered SelectEvery which seems a cool function and I play with it to try to do this field ordering.
