Quick Time Pro 7?

[Scarlett]

Are there any benefits to getting this? It's £20. My current QuickTime doesn't seem to work- when I export a movie to QuickTime and play using QuickTime, it is really rubbish quality playback, and it messes with the aspect ratio. I'm using the normal QuickTime 7. Any thoughts if upgrading would solve this? I need to use it because I am trying to export a film made on Premiere to Avid, and Avid only supports QT movies.

Not really, although you should check what you would get for your money in termas of quality improvement.
Compression of original to the mp4 format will wreck some of the quality. Some formats compress well .. some don't.
You might be better finding out exactly the required codec and spec needed for Avid .. and use something else to make the file(s)
Can't you use avi (divx) codec? Very universal, and will play on home players too.
