Quicktime has a lot of inappropriate color management being applied bugs.

It's a display gamma issue, not a trancoding one. If you take the files in question and output via Kona or Decklink, they are fine. Quicktime player is applying an incorrect display gamma for ProRes.

Either way. Report it to Apple and make sure they know.

Worthy noting is the SD version of the ProRes codec. If you still capture from analog such as Beta SP, using the ProRes SD verses uncompressed SD will save considerable hard drive space and has a bit rate of 46 Mb/s verses 176 Mb/s for 10 bit SD. Also worth exploring is transcoding from HDV to ProRes SD which should yield far superior results for typical SD broadcast than using most of these prosumer camcorders in DV or DVCAM mode when recording.

Transcoding from HDV to ProRes HD probably won't make much sence unless your mixing it with other ProRes HD footage derived from uncompresses media, or you plan to do a lot of compositing effects or keying to the clip. Delivery medium should also be considered.

This is extremely interesting to me as I just finished shooting 8 hours of HDV. When shooting I planned to crop the footage in post for SD DVD final program.

Due to the amount of footage I have been carefully researching the most efficient way to proceed and ProRes SD sounds great...

The link below shows how to capture from HDV directly into ProRes, I'm hoping there is a similar way to get my HDV into cropped 4:3 ProRes SD on capture.
