Slightly confused about the role a RAID plays in live capture; I was under the impression that the computer’s CPU does all the hard work of ingest and transcoding the full HD, then once converted to Pro Res the footage is written to the RAID. How then is it still important that the RAID is very fast, since at that point the footage is compressed? Is it because Pro Res HQ 1080i still requires very fast write ability?

Thanks for the link; I actually had already read that before going to the FCPUG Supermeet. I went there fully expecting to be on the right track with this workflow; I certainly wasn’t expecting to be discouraged by the guys on the Matrox stand of all people. That’s why I tried to get clarification by posting on the Cow.
The Matrox specs only mention live transcoding on a Macbook Pro at 720p, not 1080i which was what Shane mentioned in his response (see above). Also they say ‘with the proper storage you can capture uncompressed 10 bit’, but of course how you store 10 bit, and how you transcode 10 bit are 2 different things….
Still confused about the truth!

Thanks for the advice.
Actually that “mis” information was indeed from The Cow:

Also was told same thing at the Matrox stand at the FCPUG London meet.

Not sure what to believe anymore! If I can use a Mac laptop it would be great, because I can get free hire.
However, I don’t want to pay out for the Mini and Cineform if this workflow won’t work….
