Banding/Moire on SD DVCAM

Hello,

These stills are from a documentary called Sunshine Hotel that I made back in 1999/2000 on DVCAM.

It's having a new success on Amazon Prime and I am in the process of finishing remastering, re-color correcting and up-ressing it. I have recut the entire film in Premiere and then did the color correct in After Effects.

As you can see these areas of banding are terrible. They are like this on the master tapes. When playing they shimmy like crazy.

These and others spots have been a thorn in my side for nearly 20 years.

I would like any real solutions.

Thanks.

Up-rezzind DV footage. Ugh. I'd take 'em to a post house and get an opinion.

DV is like working with wet paper.

It's no the up-rezz that's causing it. It was alway there.

Well, you know the old saying -- "You can't polish a turd". Are you certain the field order is correct?

I haven't tried field orders. Premiere makes everything progressive, but it might be worth a shot. The footage looks good, but the blown out area are shit.

Just out of curiosity, what's the frame rate of this stuff?

I'll assume you followed Best Practices when you first cut this, i.e; if you shot 24p, you removed 3:2 pulldown to make 23.976 clips, and edited in a 23.976 timeline.

If you didn't, you're in for boatloads of grief.

Its 29.97.

The film had it's day. It ran on Sundance Channel 2002-2004 like this and no one ever complained. I just figured if I am remastering I might as well fix this along with other things I fixed, if I can.

So Dave, this is my "fix". I'm hoping that you (or other can improve upon it.

If I just set "Separate Fields" to OFF that mostly fixes my main strobing issue, but then the rest of the clip looks interlaced.

So what I am doing is in the project window I duplicate the video and then separate fields. Then in the comp I duplicate the clip. I replace it with the new video. THEN I mask of the problem area so just those show over the original clip.

There has to be a better way.

Actually that can make it look bad in another way.

Without knowing precisely how you shot the video in terms of frame rate and aspect ratio, and you edited lo these 20 years ago, it's nigh unto impossible to give any useful advice. I wish I could be more helpful, but the information's just not there.

From what you've already written, I can't help but think that you're stuck with it.

I wrote above that these were shot at 29.97.

I'm remastering so that means that I've recut from the masters in Premier.
