Re: HDV Acceptable Format for Greenscreen?

I would say it is generally accepted that the more information you can provide your keyer, the better your results are likely to be. Saying that, yes, it would be ideal to feed it a 4:2:2 clip rather than a 4:2:0 clip, but the quality gain may be minimal if you set your shot up properly. Ultra seems to handle HDV just fine, so I would at least give it a chance. If you don't like the quality you can look at other methods of ingesting your footage, but why do all that work if you don't have to?
