QT Player can be downloaded free by anyone PC or Mac.”
Not really ‘everyone’
We’ve been caught out sending QT files to clients in large organisations, who can’t read QTs because its not installed on their computer, and they need their internal IT department to approve and conduct the installation, which, in some organisations, can be such a difficult process, it becomes unworkable.
Hence, we’ve been using Windows Media files a lot; suits all PC users, and is a lot easier for Mac users to download & install Windows Media Player for Mac.
We use (I know, not everyone has this) Canopus ProCoder, which does a nice job of turning my final QTs from FCP into a variety of WMV files, either for preview (small) or full video size (for use in PowerPoint, etc.)
That’s our experience.
