Why do I need a video editing card if I have a good Graphics accelerator card w/ video in & out?

If you are satisfied with the quality of the AGP card’s video capture and do not plan on any advanced video editing, then you do not need a separate “video editing card”. However, the AGP cards with video-in are designed to capture video as Mpeg, and Mpeg is not suitable for advanced video editing.

Yes, there are. The ones I have seen were originally designed to capture variations of MJPEG, which does not work with XP and Windows 2000. To capture .avi with them on Direct Show machines, you must capture using "uncompressed" .avi with a data rate of about 10 Mbytes/sec for a 320 x 240 resolution. I do not remember for sure, but webcam quality codecs may have also been an option. I know that ATI recommended switching from their MJPEG codec ("VCR-1", if I remember correctly)to Mpeg. This software compression did not work well for me with 1.2 and 1.33 AMD processors. It may work better now with faster processors, for all I know.

Do you know of any AGP cards that capture .avi that has a more manageable data rate? I do understand that there are codecs for sale on the web that will work with Direct Show, but I do no know anything about them.
