I’d use the HVR-A1U. HD blows away SD anyday. It’s 16:9 and it’s frame size is bigger. I work at MHD, MTV’s new HD channel in NYC and we shoot our VJ segments in HDV and wrap that around 10bit Uncompressed HDCAM performances and segments. It looks fantastic. every now and then I have to capture an SD cllip, and even from a digibeta it looks like ass… with it’s square frame. you have to blow it up too to match HD’s frame size. and lay it over a 16:9 template…etc. it’s too much trouble… HVR-A1U will look crisp and nice on an HD montor. the DVX-100 will not. (I know because, have an hd monitor at home and I used to own a DVX100)
Yes you will have to render one or the other, but you’d have to do that to any DV footage anyways
if you’re worried about getting the 24p look, you can get Magic Bullet (i think) and apply the 24p filter/effect to your HVR-A1U clips. you won’t even be able to tell the difference.. forget the color issue, doesn’t sound like you’re going to be doing any green screen effect, plus people will be blown away by your DVC-PRO HD footage…
