I am curious about this as well. We have a stock footage company http://www.hdcuts.com with DVCPro 1080i HD QuickTime clips made with Final Cut Pro HD using Black Magic. From our experience the clips are made for Apple Final Cut Pro HD edit system however one of our clients was able to convert it to use for Window PC computer editing system, but I am not sure how they did it in the end. If you do find out it would be great to post it, for I have researced for other people interested in our hi definition stock footage and have not found the answer to how to convert DVCPro QuickTime to codec that is accepted by PC editing software and hardware. I would like to post it our our website to allow people with Windows to use our HD movie clips.
