the video installations I made in 2006-2008 did the following on a single Mac Quad G5 (later MacPro)<br><br>- Display live feed from 1080i camera<br>- record live cam to disk at full frame rate<br>- put live feed into 300 frame buffer and scrub through it at various rates<br>
- play up to 4 1080i clips off of two hard drives.<br><br>This was all done with plenty of CPU in reserve. The codec was AppleIntemediate which is simply Photo-JPEG with specific CPU optimizations. <br><br>You can see one of these in the lobby of OneArts Plaza in Dallas, Qualcomm HQ in San Diego and several private collections.<br>
