Jerky action shots or panning motion

[dadrab]

Good day all.

Over the weekend, I burned a disc containing episodes of an old TV show. The episodes were downloaded.

Both episode file sizes were about the same. Both widescreen format. Both were encoded to from AVI to MPEG2 for DVD using AVISynth frameserving to TMPGEnc. In fact, I believe I used the same AVISynth script for both episodes (with obvious changes for file names, etc.).

One episode turned out very nicely. The other looks…well…poor. Every action or panning motion shot causes jerky movement. In fact, the whole episode is sort of jerky. Now, the source AVI is fine, so it’s either something I’m doing during the encode or authoring/burn phases.

I usually drop my .AVS files in VirtualDubMod to check them before encoding. The one in question seemed fine at that point.

I’m authoring using Ulead DVD Movie Factory to .ISO file and burning with ImgBurn using TDK DL media.

I'm fullly aware that the problem could be a crumby downloaded file, but I was wondering if anyone had any other thoughts. I've never encountered this before.

Any help would be greatly appreciated.

^ have u checked the fps of both avi's? one may be 25fps and the other 23fps.

so if u converted to NTSC, the 25fps avi may look screwed up.

also check the DVD on the PC too to make sure its not your DVD player.

Checked that already.

The original AVIs (both of them) were 23.97 fps, so I used a pulldown command in TMPGE to be able to view it at 29.
