Live Preview for USB Digital SLRs (à la Darktable new feature being tested)

http://www.darktable.org/2012/05/live-view/ [2]

hey i found this cool new feature for Darktable

It supports USB live preview for cameras that support it like the Nikon D90 (my camera, tested to work)

Not sure how complicated it would be to include the same tech/method as a capture back-end for Kdenlive.

This would particularly be useful for stop motion. I know i've been dying to test the the stop motion utility more, and i have a little bit with built in webcam, but i can't afford a blackmagic design input interface, and i'm not sur emy computer would even support it.

I know a lot of people like to just do pencil tests on the computer so the lower quality USB preview is great. If this backend was added, any type of camera that supports live preview would be covered by Kdenlive (USB for testing and semi-professional, webcam for hobby, hdmi for professional)

but of course it would be useful in general not just to kdenlive. It would be good for people doing prepwork for shooting sessions too.or anyone wanting USB SLR capture.

Some developer might want to review the code to see what this method supports/doesn't support, and see how complicated/feasible it would be to implement something similar for Kdenlive as an additional capture backend.
