Avc (h.264) Conversion Problem

[Chetowa]

Ok, I've tried looking at this from every angle possible, and I'm lost.

 

A friend of mine sent me a bunch of videos that were encoded using AVC (H.264). Now, I want to cut out certain parts, using the Edit Video - Advanced. And while I was at it, I exported it in MPEG-2 format, since it's more friendly to more players, like winamp, etc., unlike AVC files. However, every file I convert from AVC, no matter what format it goes to, is jumpy/jittery. The image quality stays the same, but it keeps jumping, or going to slow. It just won't play smooth, like the original file does. And no matter what I do with the settings, it won't work. Any ideas?

Application, and I'm not sure on the definition, actually. It's really good quality, though, so possibly High Def. I'd ask my friend that gave it to me, but he's deployed to Afghanistan at the moment.

Any chance you have Quicktime Pro installed on your pc?

[Chetowa]

I don't have Quicktime Pro, no. I only have the very basic Quicktime that came with iTunes.

Regular Quicktime is fine. Run Quicktime player and load one of the files. Then Click on the menu WINDOW and choose Movie Inspector. That will give some details on the file.

I used Movie Inspector on the original file, and came up with this.

 

Format: H264, 848 x 480, Millions MPEG Layer 3, Stereo, 48.000 kHz

Movie FPS: 23.98

Playing FPS: 23.98

Data Size: 169.26

Data Rate: 1.02 mbits/sec

 

I tried opening a converted version of a cut-out piece of this same video, and Quicktime wouldn't even open it. Something about it not being a format it supported.

[ggrussell]

848x480 is a standard (1:1 aspect ratio) widescreen video. Not high definition, but I do see one problem - 24FPS. When I shot 24fps hidef and tried to convert it, it was REAL jumpy and jerky when the camcorder panned. So I don't think it's a codec problem. Are you NTSC or PAL?

 

You may have to run the video through another piece of software to convert the 24fps to 29.97fps (NTSC). There are several shareware apps like TMPGenc or SMART that should be able to do that.

[ggrussell]

Was this from a camcorder or from an application? High definition or standard definition?

[Chetowa]

I use NTSC. However, I tried looking for those applications, and TMPGenc, while I got it, didn't support the file? And SMART Converter, I couldn't get. The domain for the site was expired?
