Video Capturing question?

[jmcoreymv]

System
AMD Tbird 1333 mhz
MSI K7 Master
256 MB DDR PC2100
Win2k Pro w/ SP2
Asus V7700 Deluxe (used for capturing)
Santa Cruz
IBM 60GXP 60GB

Im using premiere 5.1c and Im currently capturing analog video (and audio) at 352x240x29.97fps. If I try to capture at full NTSC resolution I drop frames like crazy. Now my question is: Would installing a second IBM 60GXP GB drive in a raid 0 config with a promise raid controller allow me to capture at full quality without dropping frames? Or is it my CPU/Ram holding me down or the video capture card (even though it says it can do full NTSC)?

dude
i can capture at that with FULL frames on my athlon 1.2 with 256mb of the same ram....

but im using a radeon vivo

but still
its not your hdd that is dropping frames
i have a 20gig 60gxp

Is there a PCI version of the radeon that can capture at the same level as it? (That way I can keep my GF2 for games).

I could even capture full frames with my P2-400 and my Elsa Erazor3 !!

either the drivers are crappy or the card was not meant to be a "real" capture card. Since I work with videos very often I bought myself a good PCI capture card. Have a look at stuff from Fast or Pinnacle, they've got a couple of good PCI cards just for video captureing and editing (I have a Fast DVD-Master, not available in the US though)

Full frames uncompressed AVI (broadcast specification CC1R 601)with CD Quality Uncompressed Audio is approx 20.2 MB/sec data rate, if your hardrive can't sustain that data transfer, your going to drop frames, simple as that. Your CPU isn't going to be stressed without using compression(thats why a much weaker CPU can capture those rates), and your Ram is not a factor either.

First, instead of Premiere(resource hog), use a capture program with a smaller footprint such as Amcap, AVI IO, or VirtualDub. I use Premiere for editing/processing but hardly ever for capture because it has such a drain on your resources.

Second, benchmark your harddrive with Sandra or HDTach, to see if you can sustain that 20.2 MB/sec transfer rate, your IBM 60GXP should be able to do it, but you need to make sure you have updated MB drivers ect. Its all hardrive speed with AVI video capture.

Make sure you don't have programs running in the background.
