It's Windows-only, so I can't test it (I'm on Mac) , but I'm very curious if it will work to allow the video feed from a Nikon or Canon DSLR to be seen by TVPaint in the Video-In settings.
Just this week I had yet another in a long line of students ask me : "why can't I shoot stop-motion in TVPaint using my DSLR ?" I explained that there is a Canon Plug-In (Windows only) that works for certain older model Canon cameras , but that the only reliable way to do video capture in TVPaint is to use an HD webcam , such as the Logitech C930e (which gives very good results , but is certainly not as good an image quality as a DSLR camera).
It's not free ,but I believe a free trial version may be downloaded for testing. If anyone who owns one of the supported Nikon or Canon DSLR's would test it and report back , I'd appreciate it.
