Can't convert a 30fps WMV to NTSC CVD without jerkiness

[yukichigai]

I've been trying to convert a 30fps WMV to a suitable NTSC CVD format, using TMPGEnc. I have the rest of the settings all worked out, but for some reason the video keeps coming out jerky. I've tried 29.97 fps and 23.976 w/ 3:2 pulldown and they're both jerky, and I don't want to do a different framerate since I'd like to keep this as a standard CVD. I'm thinking I'm missing some obscure setting, since the jerkiness and apparant frame-dropping is actually in the file. (though oddly the skips and jerks show up in different places if I convert it again with the same settings) I'm going insane; I really want to make some damn CVDs. :P Any ideas?

Really need some help here. At least point my oblivious ass to the relevant thread.

You shouldn't change the frame rate from 29.97. Are you getting the jerkiness with just your media player? Try playing the encoded file with a software DVD player like Power DVD. Maybe the jerkiness is caused by the default mpeg-2 filter that your media player is using.

The jerkiness isn't in the media player. It's in the file. It shows up in the same place each time I play one specific render of the original file. And I have to convert it to 29.97, otherwise it won't be CVD standard.

What does "one specific render of the original file" mean? Are you talking about the original WMV? And I never said you should change the 29.97 frame rate. I meant that 3:2 pulldown wasn't necessary.

Okay, I put the WMV (comes at 30fps) into TMPGEnc, and the output is an mpg file. When I open the file and play it there will be jerks in it. It behaves as thought it is a playback issue, but the jerks will show up in the same part of the file every time. (ergo the jerks must be in the file) However when I render it another time with TMPGEnc, making a new mpg file, the jerks show up in different places. I'm sure this is because I'm converting 30fps -> 29.97fps, but I can't find a setting to fix it.

You can't encode at 30fps. I'm not convinced that 3/100 of 1/30 of a frame would cause jerkiness. Are you sure the jerkiness isn't interlacing? You never said whether you tried playing the CVD in a DVD software player, which de-interlaces playback. Better yet, have you burned it to disk yet and watched it on your standalone? If you still have the same problem the file might be damaged. Or maybe using another encoder would yield different results. Just a thought.
