[Avid-L2] Re: Apple HDV Codec Field Order?

Actually batch capturing HDV with the Sony HVR-1500 is a breeze. It's just as robost as DVcam is on a DSR-1500 and 1800. Turns out the trip through Sebsky Tools did in fact maintain valid time code to the original source tapes. The batch capture worked like a charm. As to levels well I'm about to find out. Thanks for the info on the codec.
