Can you convert Mpge2 back to AVI?

Yes. Go to the "Share" tab, and select "Create Video File", and use the existing AVI template, or choose "Custom" and tweak the settings as needed.

The end result, of course, won't be the same quality as the origial AVI video

Not necessarily.

First of all transcoding -- even between high-quality, high-bitrate formats -- results in slight encoding differences unique to the algorithms used. These usually show up in small scene details and near edges.

Also, MPEG2 is not a lossless format, and in the case of DVD-resolution video, it carries only about 1/3 of the data that DV AVI does, for instance. Furthermore, the AVI in question could be uncompressed, in which case MPEG2 would carry only 1/15th of the data of the AVI file.

Edit: my bad, I misread your post -- I though you wrote that it WILL be of the same quality. Sorry bobfrank!

Thanks for the edit to your reply. I was really getting confused reading your reply. I was starting to think I had no clue about what I was saying.

I'm not quite a newby, but I'm certainly no pro at this video stuff.
