How exactly do you think that he's going to get those multi-gigabyte files to and from the hard drives to be encoded?
He specifically said he did not need to capture it. So it might already be on the system, he just needs the additional drive to store the encoded material. What if the footage is DV? What good is RAID going to do then?
Have you tried opening a 2-hour raw capture?
I don't know what kind of system you are running, but it takes a few seconds to open a 20GB DV file in Premiere on my system. What is there to open if you are simply encoding the file? He says nothing about editing the material anyway.
What do you think you are accomplishing by being so outright rude to everyone? Do you think that makes your opinion anymore supportable?
