Slow down a m2v from 29.97 to 23.98?

[StoryDonut]

I've got an m2v file that plays at 29.97, but it should be 23.98. Visually I can tell that it's playing too fast, and somehow got the wrong fps assigned to it. Is there a tool that can properly change this?

(I tried re-encoding it with MPEG Streamclip, but the results were choppy and unacceptable.)

Hi-

I know nothing about Macs and what you can and cannot use with them, but if this thing is progressive, run it through DGPulldown at the default 23.976->29.97fps setting and you should be able to fix it. Don't run it in place (don't let it apply the flagging to the original), but let it create a new M2V, which is also default.

If you can find it, use PulldownX to flag your video stream with the NTSC frame rate.

I always liked the hacking approach. Have a look here: http://web.archive.org/web/20051206075748/http://homepage.mac.com/rnc/EditMpegHeaderIFO.html

Wow! Thats a blast from the past.
I would love for everyone getting into backing up their movies today to go back to the dawn of the DVD-ROM arriving in their new computers and trying to figure out: (a) how to make a backup copy of their new DVD movie thingy, and (b) asking why it took two or three days of encoding just to make one VCD of a 2-VCD backup!
