HDV and Canopus HQ codec

[T-Bone]

a dual core Intel easily supports editing .m2t

in your experience, how complicated are these .m2t edits ?

With a laptop -- a dual core Intel easily supports editing .m2t while HQ puts a very heavy load on your disk leading to dropped frames.

Since many laptop cutters use external drives you can use an external Raid0 configuration and be happy with HQ.

HDV Editing - VERY heavy on the computers CPU's as they are having to convert and add your edits at the same time.

HDV Capturing - Smaller stream and no converting needed during capture.

HQ Capturing - Very hard on the CPU's so only faster CPU's can handle it.

Editing - Easy on the computer because the decoding needed is a fraction of HDV.

just to add alittle to what stormdave said:

for obvious reasons, capturing to mpeg2 ts is easier on the system than capturing and converting to HQ simultaneously

it's the editing of mpeg2 ts that's the killer

[STORMDAVE]

Yes, if you choose to use Canopus HQ during capture, it captures to Canopus HQ on the fly. Your PC must be fast enough (Dual Core and up will be capable) to do this. Canopus HQ is a very high quality codec, so you have no worries about quality loss at all. If you want to save hard drive space and have a very (and I mean very) fast machine, you should capture to the MPEG2 TS (Raw HDV files)...

Just need to get a critical point ironed out.

When digitising HDV footage directly from from my Sony V1P camera (via firewire) into Edius 4, is the HDV footage being converted with the Canopus HQ codec on the fly? rather than as mpeg GOP footage?

cheers.
