HD footage resized in an SD sequence

Daniel N. Jackson · February 6th, 2012, 11:31 AM

Hey Everyone,

I have some DVCPRO HD 1080i60 footage that I'm trying to incorporate into a DV NTSC sequence (ultimately it's going to end up on a DVD, but we also need to export uncompressed 8-bit files to show people before that happens.)

The project is incorporating footage from a bunch of different eras in a bunch of different formats (primarily DV) but the only footage I'm having problems with is the HD footage.

The HD footage is sitting in the DV project smaller than the frame (basically, inlaid into the background image), and it's looking extremely pixelated with jagged edges. (I'm including a screenshot so you can see what I'm talking about, the HD footage is centered horizontally, a little above the vertical center. It's a hand and some audio equipment: http://www.thewoostergroup.org/proje...screenshot.png).

I've tried everything I can think of to solve the problem, mostly around de-interlacing. I'd really appreciate any advice you guys can give. I'm a little bit out of my depth on this.

Thanks!
Daniel.

Well, I can't solve the problem with trying to fit 16:9 material into a 16:12 (4:3) frame -- crop it, if you don't want letterboxing, but I suspect your other issue is caused by the different field order. DV is lower first, DVCProHD is upper first -- so if you don't correct for the insertion of the DVCProHD material, it uses the DV preset and reverses the field order. Make the correction manually and it should look much better.

Cheers,
GB
