I know it is hard to believe a Core 2 Duo can't encode a single H.264 stream, but from my basic troubleshooting, I think that is the problem. Take a look at CPU utilization while recording. Both cores are likely near 100%. I was unable to determine what codec might be better suited for live encoding. Perhaps VaraSoftware has a recommendation. If you find something, please let me know. -jared Sean,

No matter how I set the frame rate, Wirecast continually reports an FPS rate of between 10 and 14. I'm wanting 29.97. It is actually quite important to get full motion of the conductors' hands. I've tried encoding in H.264 and in DV. I also have been getting some audio dropouts, but that seemed to clear up when I lowered the frame size at the camera from 1700 down to 640 (I've always been encoding to 640, except for a brief experiment with 720). When I open the resulting file, QT-Pro also shows a FPS rate of 12 or 14. Am I doing something wrong?

Can wirecast send video out via a graphic's cards S-VIDEO or RCA for external recording to DVD recorder setop box, if so how is the video quality, similarly the projected video on the screen.

Thank you for the detailed info. Can wirecast send video out via a graphic’s cards S-VIDEO or RCA for external recording to DVD recorder setop box, if so how is the video quality, similarly the projected video on the screen.

Very interesting graphic! Maybe we could add something like this as a core feature to PaperCut? If you're running PaperCut NG 7.4 or higher, it would be interesting to publish the environmental impact stats on the popular printers. This feature represents a printer (or user's) usage in trees, CO2 and energy-equivalent. You can read more about this in my blog : http://www.papercut.com/blog/chris/2007/06/21/having-an-environmental-impact/ Just doing a quick calculation on your figures, 129,118 sheets = 1.6 trees or 1.1 metric tons of CO2 equivalent. The coefficients are referenced here: http://www.papercut.com/products/ng/manual/ch-sys-mgmt-environmental-impact.html Hi Jarad. Very interesting graphic!

I had read some similar info over the past few days, and this does seem to be a valid workaround. In the meantime, I decided to re-try using Firefox and am using <a href="http://adblockplus.org/" rel="nofollow">Adblock Plus</a>. So far, this blows SafariBlock away. There are few minor annoyances, like the inability to display PDF's inline (unless you use Rosetta and <a href="http://www.schubert-it.de/pluginpdf/" rel="nofollow">Shubert-it PDF Browser Plugin</a>), but overall, I think I'm a convert. :-) pecos bill - thanks for this info.
