Forum: avgeeks Subject: Frame Rate Problems With Some MPEG2s

Some of the MPEG2 files I have been trying to watch exhibit what I will call (for lack of a better word) a very pronounced jerkiness. From reading previous posts, I thought it might be related to a 23.97 fps file not being correctly decoded by my software, but all my MPEG editing software (and 3 different decoders) report 29.97 fps and all play back the same way.

The MPEG4 files available on the site play perfectly, but I like to make DVDs of favorite files for friends, and MPEG4 isn't of sufficient quality for that...

This problem is particularly noticeable on "The Talking Car" and a little less noticeable on "Crossroads Crash" and "Down and Out."

Anyone have any suggestions? Any help/explanations would be most appreciated.

Those problem files that have a framerate of 24fps versus 29.97. I'm working on fixing this.

OK. Sorry for asking something that's been previously discussed; like I said, everything I have that decodes MPEG2 reports those files as 29.97 fps.

Time for some smarter software. :-)

Which program are you using?

I've found some programs (like Quicktime, Windows Media Player) are better than others (VLC) when it comes to playing those files.

Just wanted to update my last post:I got the MPEG2 plugin for QuickTime Pro (I figured $20 wasn't too much considering how much I liked the software for MPEG4 transcoding/playback). All the files I had difficulty with looked beautiful and were reported as 24 fps. QT Pro has the settings to export the file with a framerate of 29.97- I'll try that and see how it does.

I've tried Windows Media Player 10(with NVIDIA DVD Decoder 1.00.67) and Nero 6.6's Media Player. I use QuickTime for MPEG4 playback (which does look great) but do not have the MPEG2 plugin. I have also tried viewing the files in Ulead's Video Studio 8 and DVD Movie Factory 3 (both of which report the file as 29.97 fps)- results are not as bad as WMP but not as good as the MPEG4s in QT... Not sure what it would look like burned to DVD, but I think I'll try it (on a DVD+RW).
