Hi, thanks for your help. I was just curious, what kind of hard drive space are we looknig at for an hour of HDV footage, say from the Sony HDR-FX1? For me, typical DV footage takes up about 12/13GB per hour of footage.
So how large do the HDV files get? What about higher-end HD cams? Thanks in advance.

HDV runs at the same dv25 spec as mini-DV (I beleieve 19.2Mbaud is allocated for video, and the rest I assume is audio, though I have only seen the 19.2M ratting.)

So plan on needing about 12gigs for an hour, just like DV. (I mean if it fits an hour on an hour long mini-DV tape, they gotta be close right?)

There is no ability to switch between 4:4:4 and 4:4:2 (I have never even heard of 4:4:2, though it may exist. typically you only hear of 4:4:4, 4:2:2 4:1:1 and 4:2:0 when talking about chromanance sub-sampling)

Other recording formats have other rates. I can't list them off from memory because I have only editted HDV footage (any job with a budget to rent me a varicam or cinealta, generally has the budget for an editor, so I have yet to deal with that)

Though I do know from the movie I am finnishing now that HDCAM is around 140M per sec. (note that this is not HDCAM-SR, just regular HDCAM)
