What frame rate can you achieve with usb 3.0 and liveview?

I don't know of any DSLR bodies that support USB3 yet.  If maximizing quality is a concern, you should really get an HDMI capture card such as the Black Magic Intensity and then use a DSLR with clean HDMI output.  That's the more professional way, but the cost goes up too.

It seems that the T3i (the DSLR I have) has clean HDMI output, it turns SD when the record button is pressed, so streaming with Black Magic would work right?

If you have a clean HDMI output, then you could capture via the Black Magic devices and then should be able to use any streaming software that supports a video capture device.

<p>I am looking to be able to use my Canon EOS Rebel T3i as a webcam on a computer, both Mac and Windows based. Some uses for this would be a HD live stream or the ability to record video directly to my computer. I know I would need to use an HDMI cable to connect my T3i to my computer. Since there is no HDMI in on the computers I will be using (or any computer that I know of) I would need a way to connect my T3i's HDMI out to my computer. I am looking at the Blackmagic Design Intensity Shuttle for USB 3.0 and the elgato Game Capture HD. It needs to be able to work with USB 2.0, as that is the only port that I have on both of the computers I would be using this with. The elgato runs from USB 2.0 and where the Intensity uses 3.0. I need to know 100% that the Intensity would work on 2.0. I also need to know if they would show up as a webcam on the computer. The apps I would be using would be Skype, EasyWorship, and an Twitch.tv.</p>
