IEEE 1394 capture using non-DV codec?

Hello,

Can anyone please answer me this: is it possible to capture video from the IEEE 1394 port using a non-DV codec? For example, I have a Matrox DigiSuite LE (without the MAX option). I am wondering if I can use the IEEE 1394 port to capture video from my DV device, but to have the video file stored using the Matrox M-JPEG codec and not the DV codec.

Is this at all possible?

Sincerely,

nate

short answer: no.

remember, DV capture is just a digital transfer, so no compression or codecs come into play. if you want to compress that footage to another format in real-time, the quality is going to suffer a lot, and since you'll be using 100% of your CPU doing the realtime compression, your going to increase the chance of dropping frames.

Long answer: yes.

It's possbile to decode the DV stream and then re-encode to something else. This is how some apps support "draft" capture, but as cheesehole stated the quality may suffer and you could drop frames. Both of these can be reduced with faster systems.
