AVS Video editor
It costs $40US. (Windows only, I think.) It goes beyond Windows Movie Maker (free in Windows). It works with most common formats, including. mov, so we can exchange edited and compressed vids across the Mac-Win barrier. It also offers some additional features effects not available in WMM.
I have also tried Pinnacle ($100). It would not show vid on my new machine and noted that my graphics card was too new to be qualified. It explained how I could degrade the performance of my system so that Pinnacle might work. This puts it in my “YOU KNOW YOU’RE STILL IN GEEKSVILLE WHEN…” box. I don’t open that box till I have to.
I am also testing Streamload, a place that offers off-site storage. So far, it seems cheap and workable. Slow on upload, But 25 G for 10/per month is a good price. You can get 5G free, with a limitation that you can only download 100MB in any month.
If I put stuff on Streamload, I can give someone else access to it. Thus, I could, for example, put a draft version online and let someone else do the final edit. The .avi files for a 6 min. vid could easily run 10 G. Not very practical to transfer A draft file in compressed form would probably be about 100 Megs. Practical for BBand.
Putting these things together means that we have wide range of collaborative options.
