Apple ProRes QuickTime Decoder 1.0 for Mac and Windows
Earlier tonight we saw the release of the ProRes Decoder tool for QuickTime. According to Apple, this tool will allow QuickTime to play Apple ProRes 422 files, using the codec that provides "visually lossless, uncompressed HD video at SD data rates" for Final Cut users. This is the first version of the codec that includes playback on Windows machines."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," says Apple.
The Mac update/plug-in can be downloaded for free from Apple's support downloads website, and if you are using QuickTime on Windows, there's a separate download.

The page says "visually lossless", not just "lossless". So it's lossy but nearly lossless?

Yeah it seems it is close to lossles which is good I guess. I saw this story though hours ago on a site I came across zollotech.com good to know though

ProRes is lossless. Many TV shows and commercials are produced and broadcast after being mastered in this format. It's efficient for storage and still looks amazing when transfered to tape. However, ProRes has always been compatible with Quicktime if you have the AppleProRes422.component installed.

ProRes 422 is NOT a lossless codec. It's designed to provide very high quality for HD production at manageable bitrates, making it appropriate for use with FCP and Xsan, but it's not lossless. "Visually lossless" "or "virtually lossless" = marketing-speak for "lossy, but good."
I amended Cory's post to include the key word "visually" from Apple's description.

FINALLY! My team does everything in ProRes its fantastic. I couldn't dream of not having it again. But for final delivery we always have to go uncompressed which is huge in both size and transfer times. I'm getting all my agencies and their production houses updated with this as soon as possible. Finally my world is much easier!

Will this work with other apps? I would like to use this codec with Blender.

@ Michael Rose
I'm not sure of the distinction between lossless and virtually lossless. Seems like you're splitting hairs here. What I can say about ProRes is that, "lossless" or not, you cannot tell the difference between footage that's ProRes vs Uncompressed. The alpha channel would be nice but not necessary (you still cannot have transparency on tape) and 4:4:4 is rare on a day-to-day basis for so much HD post-production that most HD users will never need 4:4:4.

Thanks for the link - try as I might, I could not detect a difference between the 25 MB/s and 189 MB/s portions of the image. I downloaded the full rez image and zoomed it to 400% trying to find the darn line.
Pretty revolutionary, imo. Kinda like WAV vs mp3, but w/o any detectable media degradation.

So, i am trying to import proRes into after effects running on window, and before it used to say "file not accepted" i am pretty sure, now it just crashes after effects, or premiere.
Anyone know if this is just meant for QT playback or for decoding in video editing programs as well?

Althougth it has been pointed out here that technically ProRes422 is lossy, there are two different kinds of lossy.
Formats like JPEG, MP3 and H.264 are incrimentally lossy, each time you edit them you have to re-encode them and lose some quality, which means that it keeps degrading the more you work with it.
With formats like ProRes422 and DV you throw away some material at the first save, but when edit it and re-encode it there is no additional loss of data. Therefor these formats are suited for editing because they are not lossy anymore after the first time encoding.
