As far as I can see it seems like, at least in
VirtualDub, to only support 8bit 4:2:2 lossless captures and not 10bit despite having a 12bit ADC. I suppose 12bit probably could not fit in USB 2.0 bandwidth. I thought 10bit might, but maybe not. Or maybe the ATI Wonder 200 chip internally works in 12bits but always only puts out 8 bit final results?
Do the internal cards offer 10bit?
On a side note I wonder if it is better to let some dark signal go below 16bits and some white above 235 for the RAW archival captures so you get a bit more total DR captured even if you'd then HAVE to process everything to fit video levels before playing back. Perhaps it's too risky judge, especially on the high end though even with the
VirtualDub histogram and could get one or two color channels clipped by accident? And not worth the risk for a fraction of a stop more DR? Althouhg at 8bits every bit could help were you to ever try to color grade since 8bits leaves you with no margin, anything you do in terms of levels adjusting would be a bit lossy unlike for 10bit editing. Maybe it ends up irrelevant for VHS/SVHS/8/Hi8 anyway though?
