Wavy interlacing problem on video motion?
 
I have converted some Hi8 tapes to DVD. When played on a DVD player you can see wavy lines whenever there is motion. This seems to be a interlacing issue. Thogh you would think that the DVD player and TV would automatically deal with this.

Matrox MX02 MINI transfer to Mpeg2 iframe at 15 Mpbs
Edit in Premiere Pro
Export to AVI Mpeg2 iframe
Convert to DVD using Sony DVD Architect

EDIT: It seems to have been converted to Progressive on export from Premiere Pro

I don't know what "Export to AVI Mpeg2 iframe" means. AVI is not a proper container for MPEG encoded video. AVI can't be used for DVD, which requires MPEG containers reorganized as VOB files for DVD authoring.

If the video has been re-encoded as progressive in Premiere Pro, how can you have interlace problems with progressive video, which isn't interlaced? There are occasional problems reported with PP, as it doesn't deinterlace that well, but wavy lines aren't usually reported. DVD is usually interlaced to begin with, but many devices will treat progressive DVD as interlaced anyway -- that's what they're programmed to do, even with progressive scan players.

This all seems rather convoluted. I don't think anyone here would know what you mean by "wavy lines" without a sample.

The interlaced setting was set to lower field. For NTSC it needs to be upper field.

I'm sorry, but you're really confusing this thread. I thought you said the output was converted to progressive video by PP. Progressive has no fields, so the field order is irrelevant.

This is going nowhere without some kind of sample, either of the original video or the final output. The original would be best.

As sanlyn states, attach a sample for us. :)
