For those who share their ProRes projects cross platform, or just like to get it to play on a standard system... this tidbit is for you.
"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. "
