Is anyone aware of any systems for any hardware/operating system platforms that will, effectively, turn a computer into a VCR? What I'd like to do is connect a video camera to the computer and start recording (on the computer) EVERYTHING that comes through the camera and store it on disk. I realize that this will require a lot of disk space, but it is what I'd like to do. I don't want to have to record to a VCR or lazerdisk and grab frame after frame after frame (as I do now). (Please post or I'll post summaries). Thanks, --- Keith Freedman Los Alamos National Laboratory freedman@ilmen.lanl.gov

Computereyes in Australia have just announced a board that captures video in real time to a PC hard disk. The sequential frames are saved in animator .fli or Linkway format. I'll post the address and particulars if you are interested. J.Sawers@uts.edu.au ph: 61 02 330 3904 Computer Network Manager Faculty of Education, University of Technology, Sydney, Australia

One caveat: To replace the full functionality of a VCR with a computer based system, you're looking at BIG dollars. Low-end small sofware based Quicktime video segments are bad enough, but full screen full fps hardware-based QuickTime videos mean gigs of Hard Disk and an expensive video board, not to mention a fairly powerful computer... However, those concerns aside... Any of the many existing Quicktime capable boards on the Macintosh platform such as those listed below will capture live video (and sound either via the board itself or through the Mac's Sound digitizing capabilities or MacRecorder or similar). These boards save the video to dis at small resolutions and frame rates (typically 10-15fps, and 160x120 pixels). They have the advantage however, that the Quicktime video segments play back on any 68020 Mac or greater without those Macs also needing extra hardware like a card. -SuperMac VideoSpigot, VideoSpigot Pro, VideoSpigot and Sound -RasterOps 364, 24stv, 24xlitv, 24mxlitv, MediaTime -VideoLogic -MoonRaker etc A number of these cards, namely most of the RasterOps boards are upgradable in the future with the QuickPac daughter board to give full screen, 25 or 30 fps video capture and playback. This is due in May. The RasterOps ImagePro has been mentioned in previous postings as capable of Motion JPEG compression and apparently gets near to the mark re full screen, full fps. Several cards are already shipping with 640x480 full screen resolution, full frame rate, video capture and playback: -the EyeQ series of boards using a DVI chip (see prev posting re. DVI) -the Digital FX and Soft FX Off-line Video editing systems. -the AVID series of Off and low-end On-Line professional editing system.
