I think it has to be a new blue efx problem and Vegas Pro 11 as I just tested a 1440 HDV to MP4 with a chromakey pluggin and it renered fine, but I noticed the blur in Vegas’s keyer doesn’t work now. It puts a blury shadow half way up the screen. Just when I thought Vegas’s chromaker could be any worse. HA! Thank God I don’t, can’t use it.
