Sure, but don’t they use a proprietary codec based on the same architecture? It really doesn’t matter. All I’m saying is, it seems to be the ‘missing link’ in FCPs ability to handle mixed resolutions. There’s no unity between. say, DVCPro HD, DV, and uncompressed 8 bit codecs. It’d be cool if manufactueres such as AJA, or Blackmagic amde a scalable codec that was either supported in their hardware or fit in to FCPs rt architecture to be able to handle mixed resolutions. It’d amke a bunch of us really really happy. Also, it’s would improve all of our worflows tremendously.
