Converting mp4 to ne Windows and Mac Compatible

[essdeeay]

I'm using Avanti for this, but I don't think it's an Avanti-specific question. I've bene given a 3.5Mb .mp4 file and I need to convert it so it's readable by both Windows and Mac but without any additional software. I use VLC to play it myself, but standard Windows builds can't read it.

Which Codec/Container combination do I need?

Many thanks,
Steve

Most mp4s(avc/h264 video and aac audio) should work fine in WMP 12+ and Mac osx quicktime player.

Can you post the video and audio details from the mp4? Use www.videohelp.com/tools/mediainfoxp to get the information.

What a great little program - thank you! In the end I went for MPEG-4 with default container and it produced an AVI file. I tried random bitrates/framerates etc. and got something of similar quality and a little less in size, but as I said it was random, and there was no knowledge whatsoever in what I was doing.

I've posted the info below anyway, so I may be enlightened as to what I *should* have done!

Many thanks,
Steve

You might try some experiments with Handbrake, exporting to an MP4 container, and seeing how the results fare on both systems.

That should work in wmp 12. If not try reconvert to a new mp4 with handbrake or avanti.

If you want it to work in all windows versions must you use wmv or mpeg1/mpg(mpg1 is not recommended for any hd video). BUt wmw wont work directly in mac os.

Avi (divx/xvid/mpeg4 video) wont work directly in mac os either.
