Hd movie burn to dvd problem jitteriness

Hi Mary

As your source footage is 29.97 fps and NTSC DVDs are designed for that frame rate, that’s not the issue.
Your DVD playback is periodically (regularly) going fuzzy? This sounds like the GOP length is too long. The I-frame (which has all the picture information in one frame) begins the GOP and then as playback continues with frames containing only some of the picture info (P and B frames), the picture gets worse until finally another I-frame arrives to restore clarity.

As your source video is so short, you also should be able to set compression to the highest bit rate allowed. If this is the only video on the disc, I would compress at 9 Mbps. There are two variables that relate to GOP length, M and N. Set N=15, M=3 in your compression settings.

I haven’t used DVDStyler, and I don’t know what other software you have. If this is the only time you’ll make a DVD, then just dig into the settings within that program to fix your compression parameters. But if you’re doing DVD authoring more often, you should do compression outside your authoring program. Letting the authoring program do the compression is fine for quick-and-dirty discs, but not for discs you want to look good. Use Apple Compressor, Adobe Media Encoder, or something else for compression, then put the .m2v and .ac3 files into your authoring software.
