Thanks for the quick response. But I'm a bit confused - I'm just a weekend editor at home. :-)

I don't see FMP4 video as an option when I try to render to a hard drive. I can choose save as AVI, but don't see FMP4 or FFmpeg as options even in the advanced "custom" settings. Do I need a plug in or maybe some other software? Using Vegas 8 Platinum.

You can't do it with Vegas. You need to use the command line app ffmpeg or an app that uses ffmpeg. I just encoded a video using ffmpeg, and I can show you how to do it too, but you need to test it for me first.

and tell me if it works on your Blackberry or not. If yes, tell me what your source footage is: is it widescreen or 4:3? (in other words, is your camcorder widescreen?)

or an app that uses ffmpeg

I use SUPER to convert video to m4v for my iPod. Should work for you.

m4v and h.264 does not work on the Blackberry. Apparently the Blackberry requires an XViD kind of file (mpeg4), *but* not with the xvid encoder because xvid is mpeg4-asp. The blackberry requires mpeg4-sp, but in the .avi container, which is uncommon. At least this is what a blackberry-oriented app does when i checked it earlier.

I just checked SUPER for this particular format and it creates terrible quality video, and it can't deal with widescreen qvga: it puts the pad on the wrong side!

I am afraid if you want to do the job right, you will have to delve in to the command line. FFmpeg has its own bugs, and adding the bugs of its front-ends, it makes one big nasty experience.

Thanks for all the great support and help. What I was afraid of is that I wouldn't be able to do it inside Vegas where I'm editing the video. The blackberry desktop software has something that will convert it if I render it to an avi that works ok. Just was hoping to do it with one less step and inside Vegas.
