Everything else will freeze, except the video...happens with Hack TV, teh Apple Video Player and others... I'm *trying* to record in 640x480, and the computer CAN handle it (500Mhz Sonnet CPU) but it just randomly locks up. Otherwise *VERY* stable... b |

Quote from: "dpaanlka" Does it lock up when recording smaller video? I've tried transferring some of my old VHS recordings (cartoons, mostly) using my 5500/250 (128 MB RAM, 20 GB 7200 RPM HD, Apple TV tuner card w/ A/V modules), with VCR plugged into TV tuner, later tried through A/V jacks. Resolution at 320x240, 240x160, no compression (figuring the compression would take extra CPU cycles that it might not be able to spare. The 5500/250 locks up every time, if I try to record more than about 20-30 seconds of video. Obviously, trying to record a 20 minute (as long as I'm having to stop recording every 30 seconds, anyway, I might as well edit the commercials out) TV show would be an exercise in patience, and require QT Pro to seem the resultant 40+ elements together. I've tried System 7.6.1, OS 8.6, and OS 9.1. I considered purchasing a G3/500 upgrade, to see if the processor is just not up to it. I've tried using a Firewire 400 card, but the 5500 doesn't boot at all with it installed.

While I am not positive on this I believe that over the years there have been reports of video problems with Sonnet upgrades. It might be worth investigating this avenue. Video capture done with the onboard video inputs is done via DMA of the data from the VRAM directly to drive controller. The data is dumped raw in a first pass and once the capture is stopped the software goes back over the raw data and creates a clean file. This process is very sensitive to timing issues on the bus and I would not find it surprising that subtle changes made by a third party cpu adversely effect the process. bill

What video capture software are you using? Perhaps try something else, like QuickFLIX!
