Are Intel centrino duo cores fast enough?

Does anyone know if the Intel Centrino core duo 1.63 gig chips are fast enough to work in a lap top for recording from the HVX200 to DV Rack? I'm looking at a Toshiba with 2 gig of memory but I think it has an integrated graphics card. Not sure.
Any feed back?

Thanks, :dankk2:

I've got a Mobile Centrino 1.4GHz with 768MB of RAM, and I get about 80 to 90% CPU utilization when recording 720/60P using the beta version of DV Rack. Since DVCPro/DVCPro50/DVCProHD is intra-frame compressed rather than inter-frame compressed, it is easier to decode and process than HDV even though there is more data. That's why a system that doesn't meet the minimum specs for the HDV Powerpak can still handle capturing from the HVX200.

The Core Duo system should have no problems whatsoever, and I would have upgraded to one if my existing laptop had turned out not to cut the mustard.

Wow, that's interesting!!! Thanks for that info; wasn't aware of that.
 
Keep in mind that DV Rack just dumps already compressed material to disk, it doesn't have to do much to the data.

The only reason for decoding the data read from the Firewire port is for displaying it and running it through the scope etc. If you have a slow CPU (as in my case), it won't matter a whole lot if occasionally you should fall a frame behind, because you can just ignore it and deal with the next frame.

If you are reading an HDV MPEG2 transport stream, guess what? You've got GOPs that all depend on one independent frame and all subsequent partial frames. Without them, you've got nothing, at least not until you get to the end of the GOP and a new independent frame is received. Capturing HDV is much less forgiving than DVCPro/DVCPro50/DVCProHD, and the same caveats apply to tape as well.
 
Thanks THoff,

Really gonna' show my ignorance here, is 720/60p Hi Def?

Thanks,

Thanks all! I love this forum. What a great place to learn and share what we know. Wouldn't it be great if the world worked like this.

Don't get me started about president gasman, but that's for another forum and yes, dollar gas would be great again, but dream on!

Agreed. The only thing that could make it better would be for Jarred and Barry to start a huge DVXUSER production company in NZ or somewhere else exotic like that and invite us all to quit our present jobs and join 'em on the beach.

I've already got a call in to Brooke Burke to see if she's interested in being my first assistant camera . . .

(it was either Brooke or Hudson . . .)
 
Hard drive speed will be a little more important with DVCProHD - you will want to keep your capture drive defragged on a regular basis. DV Rack will warn you if the drive is running too slow for long-term capture.
