OK, Now Re-Interlace It.

We did a reference NTSC video for the animators which we shot--on purpose--with a Canon XL1 in "Film Mode." This made it enormously easier to capture and fool with inside the computers. No interlace motion artifacts.

I don't know what the actual job is, but I can bet when we get done adding stuff and manipulating the sequence, they're going to want to play it back to a DVD or possibly a QuickTime of some sort.

That's when they will be horrified to find that NTSC non-interlaced video is jittery. It looks as bad as PAL does normally.

So now we need to re-interlace it--guess at the missing fields, we assume by interpolating between the existing frames.

And I would do that by..........

Good question.

Assuming 3-2 pull down type of thig is not what you want. - just rendering out to a DV codec won't do it - you'll get interlaced - but no motion between fields.

I'd try it by using anything Optical Flow - just not slow motioning it looking both forward and back temporaly.

It might work - It might be horrible.

I assume that's a separate program? It kind of kills you that Final Cut works on full frames only. You can specify what field you want to work on in a Flame.

If they want it that bad, maybe I'll call in a few favors.

It's in Shake. And I think one other program.

Also Boris Red or Blue. Several others. Usually used for Slow mo - but the important part here is it is doing a temporal analysis of pixel clouds and so will give you true interlace even without the playback speed being altered.

Oh that's good. This is me printing this thread.
