Finding the hacked 8600 video capture; from German hacker?

Need help finding the driver/hack to enable a powermac 8600 to capture video at higher fps: think it was 30fps at I believe it was 640x480? I remember a german person hacked a file or something to enable what I previously mentioned. If someone know what I'm talking about and can help me find it I would appreciate it. I have a aftermarket scsi card with a 160gb scsi drive and 4mb vram;with a radeon 7000 pci card with dvi to help. Thanks

I was under the impression that the onboard capture on the 7600/8600 was already at 30 fps (60 fields per second)/640x480 capture.

The chip used is a Philips SAA7xxx series if I recall. That chip should have no problem capturing 720x480/576 at 29.97/25fps (NTSC/PAL). Apple's software may limit it to lower resolutions though. Not surprising as a stock PPC from that era doesn't have a fast enough CPU or storage subsystem to handle full frame SD video.

No way buddies,

Even on a beige G3 it's 320x240 @ 15FPS.

If you want a 720x576 @ 29.97 or 25fps with 16bit @ 48 or 24 Khz audio, you should buy my Canopus ADVC1394 PCI card.

It does native capture in DV format so it's 12Gb/Hour... thus very few Mb/s & very low CPU.

yea, or a chipset that does encoding/compression on the fly.
