Apple - Support - Downloads - Apple ProRes QuickTime Decoder 1.0 for Windows & Mac

Finally. A way to view Prores...on Macs (without FCP) and Windows.

Of course a Windows encoder would be nice too for workflow. And it'd be doubly nice if someone would come up with a way to pass alpha channels along with compressed HD.

The Apple ProRes QuickTime Decoder software allows both Mac and Windows users to play Apple ProRes files through QuickTime. Apple ProRes is a visually lossless format that provides uncompressed HD quality at SD data rates.
It is an excellent choice for mastering and can easily be transcoded to distribution formats like H.264. With new support for playback on both Mac and Windows computers, Apple ProRes can also be used for review and approval of Final Cut Studio sequences.
