Hello all.

I was thinking about trying sme full frame video capture video the Svideo inputs on the MT G3 Beige I have running at 366. Is this possible to accomplish? Tyring to make some VCDs of some music videos.

Any help would be great. Thanks in advance!

I guess it depends on what your 'full screen' is. Normally about 640x480 - I guess. I was able to go 320x240@11fps smooth on my 7600/180Mhz AV setup. Never tried a G3 system. Strangely with compression turned on it became choppy running from 20fps to 8fps (something like that) but I'm sure a native G3 system is better suited. You probably want to have about 20GB partition (drive) dedicated to the video capture and I guess you could probably use the built-in software. Make sure you have some good drives - uncompressed full screen can chew up space quick. Good thing drives are cheap!

QT Pro should be able to save out in mpeg1 format.

You get the smoothest (highest fps) video capture when you use no compression, because the computer doesn't have to 'think/compress' anything before writing it to your hard drive. A variety of things can affect your fps's. First, you need a FAST hard drive on a FAST connection (regular [5 MB/s] and Fast SCSI [10 MB/s] don't cut it). Also, you need to make sure that your monitor is set to the same number of colors as you're capturing (having your monitor on millions while capturing a clip at thousands affects the capture rate). With these few suggestions said, my 8500 (upgraded to a G3/420) can capture video with 16-bit, stereo, 44 KHz audio to my 7200 RPM Maxtor IDE hard drive (controlled by a Sonnet Tempo 100) [this configuration gets throughput of 25+ MB/sec according to ATTO's benchmarks] at 320x240 @ 30 fps. At fullscreen 640x480, I've not been able to come anywhere close to 30 fps with the same configuration (I'm thinking it was 10-18 fps). Although, I'm not sure how it might be different on a beige G3 which has a faster bus speed.
