Jerky Image

[edwindark]

After a I burn my converted AVI to DVD, the DVD movie has a jerky image. Sound is fine. The DVD image is also jerky when I play it using my DVD player on my Mac. However, when I play the file using the VLC player, the image is fine.

Thanks for any help,
Edwin

Much more info is required. Software used, framerate etc...

I burned the DVD to a DVD-R using my Mac's burner. I'm now trying it using Disk Utility to see if this makes a difference.

Here is what I used to create the DVD: FFmpegX 0.0.9x mpeg2enc mpeg2, 720x480, 4000 kbps, 23.976 fps, no crop

I'm a neophyte to this and this is my first attempt at creating a DVD from AVI or other format.

Thanks,
Edwin

Since this appears to be a Mac related question, you would likely get better answers in our Mac Forum. Moving you.

And welcome to our forums.

FFmpegX 0.0.9x mpeg2enc mpeg2, 720x480, 4000 kbps, 23.976 fps, no crop

My guess would be that the NTSC Film framerate (23.976 fps) is the cause of a jerky image.
To fix that, you'll need a so-called "3:2 pulldown". Next time set the Set 3:2 checkbox.

(Alternatively, you can also add a 3:2 pulldown to an already encoded mpeg video file, by using the Pull tool. Input here is an elementary stream (video-only file). You may have to rename your .mpv file to .m2v, because this tool is picky about the suffix. Then multiplex the video-with-pulldown with your audio in the Mux tool.)

This leaves your video unchanged, except that playback equipment now knows how to feed it to NTSC output devices (e.g. a tv), dealing with the desired 25% more frames (23.976 to 29.97 fps) and interlacing. Result is a smoother playback.
