DV doesn't care about interlacing. That's your camera's business. Some models allow you to switch off interlacing, i.e. they send only a single field at full resolution. Has a drawback when capturing motion of course, as you're sort of decreasing your sample rate. Nothing libdv should care about, though, I think. Regards, Daniel. |
