    best res? Apple pro res or DNxHD 220x

    Apple ProRes 422 (HQ) and Avid DNxHD 220x is offered me on new project, any opinions on which gives the best workflow on MC 7, thinking harddisc space and Avid performance? And is there any difference in end quality ?

    They are very similar codecs. The avid DNx codecs are fixed datarate so always use a predictable amount of space per minute. ProRes is variable so you may save space on some content.

    However Avid is designed to work with DNxHD so you should get better performance from DNxHD than ProRes but I don't imagine it's a massive difference.

    Really depends on what the source is and ultimatley what you need to deliver and archive.

    I'm not keen on ProRes because Apple restrict deployment of the codec.

    If your on a PC, I would recommend using DNxHD.

    I have encountered a couple of issues with ProRes files that are specifically PC related. First, while you can AMA/Import the footage okay and edit okay; you can't export at all. You have to transcode to DNxHD on export. Second, AMA/Importing ProRes at matched frame rate works great. But, if you need to change the framerate of footage, during import, you have to transcode to DNxHD. For example, you have some 60p footage you want to ingest at 24p for slo-mo. Turn on the IgnoreQTRate option and attempt to import the footage. Avid, depending on version #, will either error out or force a transcode to DNxHD for the footage.

    Neither of those issues exist in a Mac environment. They are both artificial limitations created by Apple.

    -And these processes will truncate the media to 8 bit.

    Another reason (Yeah, I know you are already convinced!)

    My old MacPro 1.1 baulks at Prores but plays DNxHD media fine.
