Convert MP4 & AAC file Help

[rorschach]

I've got lots of converters and know my way around encoding/converting now but I'm just stumped how to make an MP4 video with an AAC soundtrack converted either to DVD or AVI? (AVI pref'ed)

I've tried FFMPEGX, VisualHub, Toast 8. The video, as played back by Quicktime has a stuttering video playback that plays okay on VLC with the audio, BTW. In encoding via FFMPEGX, I was able to get the video to playback smoothly after encode (deinterlace?) but the soundtrack doesn't work. I was able to separately extract the soundtrack via both Toast and FFMPEGX and into AC3, but muxing the two streams via FFMPEGX doesn't playback on my DivX DVD Recorder. In fact, it doesn't playback with audio at all. I know the video should be good as AVI, I know the AC3 is good, so why doesn't it mux well? I get no picture on the DVD player as a result.

Any suggestions? Thanks. Yes, I tried something called Hawkeye, and that doesn't do anything either.

Aha! I think I've solved this myself. Here's the procedural:

1) Load the MP4/AAC file into VLC which plays it fine complete with audio; transcode the file into DivX and use MPEG audio. Export as ASF file.

2) Take the ASF file and drop it into VisualHub and convert to DivX Home Theater profile. And then, that will play in your DivX Certified DVD Player.

Hope that helps...

Thanks for posting this. I have been having trouble with converting some MP4 files to play on my DivX player after trying a whole bunch of supposed converters, encoders, and even following tutorials posted on the web. I am going to try your solution out and see if it works out for me.

Oh, nevermind. I don't have a DVD burner on a Mac, only a CD burner. I guess this would get the files converted so I could burn them to a CD, but I would prefer a DVD. Suppose I am off again to find a Windows solution as well...but I will give this a try on the Mac if nothing else seems to work.

I need to pay more attention to the forum my search results are in.

I believe if you don't have a DVD burner you can STILL add an DivX AVI to be played by a DivX-certified DVD Player on a CD by burning not as a DVD-ROM file, but as an ISO file. Using Toast, you can put the files there, and then play via the CD. I've done that many times on a CD-RW when I only want to play a small file and think it's quicker than a DVD-RW.
