I would like to second (or third) the opinion on this. This is a rare issue, thus folks may come upon this every couple of years. It just saved my life – or at least several $100 dollars I woulda lost along with a client. …and the post is over two years old now.
Downside to the solution, is it seems this codec will not install without the Quicktime bloat/spyware. Anyone know of an alternative codec for AppleProResDecoder.qtx that doesn’t require the evil of Quicktime?
Seems Quicktime Alt does not yet support this format.
