Anyone use this to capture from the optical of a camera and encode bypassing internal camera compression. Wondering if this is a better format than HDV (quality wise)
Thanks

I answered this on the Sony Vegas forum. Take a look.

Hi Scott,

H.264 is full resolution codec and will store a full 1920 x 1080 pixel image. By comparison, HDV deliberately loses some of the picture and saves it at 1440 x 1080 to keep the data rate low.

HDV uses 4:2:0 chroma subsampling whereas H.264 Pro Recorder uses 4:2:2 so the color is better with H.264.

This does not mean that you should rush out and convert all your HDV material to H.264 but if you have a choice of acquiring new material in one format or the other, I would suggest choosing H.264.

I have not been able to see and "system requirements" on this unit..I currently capture via firewire to laptop and tape on my Sony FX1's. The picture I see is MUCH nicer on my component preview than the HDV codec that I am recording to. What are the computer requirements for this unit? I have some older laptops that do fine with HDV, and since it is a hardware converter, is the computer just capturing data?
Thanks for your help!!

Ditto, don't see minimum system requirements. At the very minimum (pun intended), would like to see "any computer with a USB 2.0 interface able to capture up to 480Mbit/s (60MB/s)".

It would be great to know the minimum OS requirements; how to set or change encoding data rates if possible; what are the pre-set or maximum encoding data rates for a given incoming signal.

Thanks!
