Drwn, thanks for taking the time to reply ,I would do my own post-work on a professional compositor so the motion blur etc is not an issue, and render times are co-measurate with quailty so that's fine too, what I need to know is how high a resolution vue would allow me. I work from a broadcast workstation whose codecs allow me up to 2k (film resolution) and need to know if vue has a bit depth that could manage that ( althugh as I say I would be happy with just generic broadcast, 720x576 pal ,uncompressed. Does it give the option of saving to fields? Is it capable of 10 bit ( image +alpha)? again thanks for helping out on this
