<br>what resolution you were recording SDTV at..</blockquote><div><br>Actually, my math says there are 5.3 - 6 times as many pixels in an HD frame than a 720x480 SD one. <br><br>Tom's Hardware says that an E6600 c2d will encode video approximately
3.2 times faster than my 1Ghz PIII. <br><br>Of course, encoding 720x480 RTJPEG only uses about 50% CPU on that PIII. I used it as a combo BE/FE until I built my first HD frontend. <br><br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br>Considering that modern CPUs are hard pressed to play back HDTV<br>streams without hardware acceleration, encoding them on the fly seems<br>like a tall order.</blockquote><div><br>I'm not saying that it would be easy to squeeze uncompressed HD down to 12mbit at good quality, but there is a large range of compression levels between there and uncompressed.
