if you plug a firewire HD into a firewire card in the laptop, can you then capture video by plugging a MiniDV camcorder into the back of the firewire HD, and save the captured video on the firewire HD? therefore saving at a 7200 rpm, and getting better results than with a 4200/5400?

Thanks once again in advance,

Dave

Yes. You are not actually capturing video, technically you’re just copying over already digital-form data.
Firewire 1394a supports 100, 200 and 400 Mbps but can the camera downstream at 400 Mbps (47,7 MB/sec), to justify the need for a superfast HD? The performance might be somewhat degraded due to shared use of the firewire bus (camera to CPU downstream, simultaneously with CPU to HD upstream) but assuming firewire supports bus mastering this might not actually be a major issue.

Yes I think so!

Not tried. But I tried firewire HDs and they have an exceptional performance, if the laptop is not the bottleneck.

Yes, if the computer is fast enough. Remember that the data are going from the camera to the computer, then from the computer to the HD–NOT from the camera straight to the HD!
