Pan & Crop without combing?

I've got some 4:3 footage that I want to crop to 16:9... but it just creates combing...

Anybody any advice on how to eliminate this?

Cheers

What if you create a new track 1 and use a Mask instead of Pan/Crop.

'cause that would windowbox. i don't want to do any letterboxing, i want to have it full widescreen, anamorphic.

there must be a way, because even Pinnacle can do it without combing, and my widescreen TV can do it... haha

I thought to get true anamorphic widescreen you had to shoot the footage that way.??

I shoot in 16:9, I output in 16:9. No masks are used. I have 4:3 footage and if I'm going to be working ona 16:9 project, I'm going to have to make the 4:3 footage 16:9 - which means, zooming in on it until the x-width fills the 16:9 frame.

No masks are being used here.

But when I zoom in on the 4:3 footage, it creates combing...

Oh wait, it seems track motion does the job... i'll just try it...

hmm, just tried both methods and all of a sudden the combing is gone... strange..

If the aspect ratio of your source media and your project frame size differs then you may experience unwanted results (at least I have in the past).

Try turning 'maintain aspect ratio' on and off to see if that makes any difference.


Edit: Just seen your last post - got called away while I was writing my response so didn't realise you'd resolved the problem. Glad you got it sorted.

Um...

Are you rendering at "Good" or "Best" quality?

I've experienced the same problem. My workaround was to render out to an intermediate format like PicVideo at 720x480p, before going to my final render. This resulted in a flicker free progressive mpeg2 output. Perhaps it will also work for you going the other direction.

Yes, you should resize de-interlaced material, not interlaced (unless the new height is 1/4x, 1/2x or 2x the old height).

I render at 'Good' because that's the default, should I render at 'best'?

Also yeah the combing has come back on another project of mine... hmm. Maybe I should just try deinterlacing it... I suppose I should try and do it so that the deinterlacing comes BEFORE the crop?

Ahh yes, that works.

When RESIZING - render at Best. Otherwise, Good is usually fine. You could try it both ways and see if it makes a difference.

ah so you mean like, if I'm blowing up a 4:3 image to fill a 16:9 frame, I should render at best?

Especially if you're zooming in on a photo (for example). Pan/Crop uses the full resolution of the underlying media where Track Motion zooms in on the video frame.

oh... so is it not wise of me to zoom in on a 4:3 event using track motion? 'cause that's what i've done, then I've used pan/crop to pan and scan... what exactly is track motion for then?

I generally use Pan/Crop to zoom IN and/or crop.

I generally use Track Motion to zoom OUT and adjust position.
