how do I capture @640x480 AVI?

[klumbz]

I'm trying to capture from a vhs tape that was copied from from a camcorded tade. The quality of the tape is pretty good. I want to get a decent capture but using MMC7.1 at 640x480 AVI using huffy codec I get only 41% of the frames, Using Vdub I get around the same percentage of dropped frames, and it's using 100% cpu.
Using lower res like 352x240 captures w/o a single dropped frame and only 20% cpu usage.
Is this normal? or is there something I can do?
My system:
Asus A7V133, T-Bird 1.2ghz, 768mb Crucial pc133, Radeon 64DDR VIVO (for capture and display) Fireball 10 gig for os, Maxtor 45 gig for captures, both are ata100 7200 rpm drives on the onboard Promise controller (udma5)...
Thanks

Got the same problem with this system to not sure what the problem is but takeing it back my PIII 866 out dose it hands down. Not sure if its the motherboard or its the AMDud.

tww1,
What are your system specs? maybe we can narrow down the problem to one or a few hardware similarities.

here's my question. i am using the same software and the huffy codec. how can you change the resolution size of it. i can only choose like 320x240, 480x240, and others. but they all have to be somethingx240. how do you change the 240. does the video card control that?

alucard2050,
In VirtualDub choose "Set Custom Format" in order to choose a specific resolution to capture at.

try using a different codec like mjpeg or maybe uncompressed and see what happens.

Has anybody done a full resolution successful capture with no frame drops using the athlons 1.2ghz and 1.4ghz cpu and whats you system specs

[alucard2050]

i have tried the set custom capture. thats were i can select the size but like i said everything is ***X240.

You could also try removing all unnessary cards out and then capture.

I solved my problem capturing at 352x288 25fps on my 300mhz system by just replacing my 2d PCI graphics card to an agp card which obviously freed up the bandwidth on the pci bus so the pci capture card could take full advantage of the pci bus

If you are dropping frames because of processor performance try using Mainconcept's DV codec and capture/compress your analog sources in DV format with AVI_IO, VirtualDub, VS5. I see about a 10% reduction in processor usage and the capture file size is about 1/3 the size of a same video clip compressed with the PICVideo codec. Mainconcept tech support says you can use the codec recompression up to 8 time with nearly no effect. You can filter and frameserve with VirtualDub.

Caveat: Mainconcept codec supported frame sizes:
FrameSizes in Pixel (for 1.25 and 16:9)
PAL 720x576, 25 Fps
NTSC 720x480, 30/29.97 Fps

For you LSX35 users. With AVI_IO you can capture DV video type 2 or transcode your DV Video type 1 to type 2 and encode your video with LSX35 using MainConcept's codec.
