Hi Bmoneymedia,
It really depends what you want the media file to be.
If you want the media stored in a cross-platform, high-quality form that can be used for anything, then you could try exporting out as as an uncompressed Quicktime file (compression set to ‘none’) – though this will result in a big file that has media 100’s colourspace locked into it. Of course you could always just keep it in the Media100 codec by exporting out as a self-contained file.
If you want a high-quality but small file that can be played on the desktop to show clients, or FTP’d somewhere then I would suggest QT7’s H264 MPEG4 codec. If PC usage is important and you don’t want to depend on clients installing QT, then try WMVs.
I do think though that a one-size-fits-all approach may not work, and you may end up with different versions for different tasks. I always seem to end up keeping the media, a self-contained export, an MPEG1 (my clients love them for some reason), a WMV, a QT and more often than not an MPEG2. I am hoping MPEG4 will replace most of these though.
HTH
