View Full Version : Premiere DV-AVI to Encore to DVD - combing/horizontal lines on TV

Been working on this problem for ages and am pretty frustrated.

In short: Microsoft DV-AVI files created with Premiere Pro 2.0 and authored with Encore always result in DVD discs with combing/horizontal lines on a television screen. These are interlacing artifacts right?

I don't author DVD discs or .m2v files directly with Premiere anymore because my large projects have become unstable when attempting to export that way. But AVI files export without issues, so avi it must be and I need Encore for my DVD authoring.

I've tried various combinations of settings in the Adobe Media Encoder in both programs but with no success yet (upper field, lower field, progressive, deinterlace etc).

I honestly still don't fully understand this interlaced/progressive thing when it comes to editing, exporting and authoring.

Premiere project details: DV NTSC 29.97fps 16:9 lower field.

All clips within the project are 23.976fps, sourced from VOB files via AVIsynth scripts

AVI file export format: Microsoft DV AVI.

By the way, when Premiere Pro was stable enough to export this same project as a progressive .m2v file, I was able to author perfect looking DVD's when I imported the .mv2 file into Encore (which in this case Encore only needed to encoded the audio file for me before writing the DVD).

Just yell if you need screenshots or more detailed specs.

Any help would be much appreciated :)

You stated you've tried many things, so you may have tried this idea already. Take it with a grain of salt, as I'm no expert.

Recently I struggled with a project where my DV source itself exhibited ghosting. (My capture device always captures DV, NTSC, BFF.) The program was a sporting event on location in PAL country broadcast a few weeks later in NTSC country. It appeared to me, although I can't prove it, that the program was a combination of NTSC footage and PAL footage because about half of the broadcast seemed "off-speed," but only from certain cameras. I'm not talking about slow motion replays. More like a sloppy conversion between 25fps and 29.97fps on the network's side.

At any rate, I removed filters one by one in my script until there was nothing left, and the problem remained. In desperation, I tried a "reverse field dominance" and that did the trick. I can't say much more about it because it's over my head, but that's what I went through and that's what fixed it. You might try to reverse the field dominance on a small sample and see if that does anything positive for your project.

Good luck.

I'll give it a try.

Someone else also told me it might be a field order problem.

Thanks.
