Re: Making standard def Hi def

Apple's new Compressor 2 has some deeply impressive scaling and temporal upsampling algorithms from Motion. Optical flow resampling, statistical scaling, etcetera. It looks to provide excellent, tunable quality for format conversion of this sort. However, it's enormously slow - about 6 hours per minute of source on the fastest Mac today in my tests so far, with HD to HD conversion. SD to HD might be a lot faster. I did a 1080i60 to 720p60 conversion with it which was pretty much perfect (not that this is a particularly stressful conversion).
