I have a few questions about virtual production. Does anyone know if it is possible to SDI out to put Motionbuilder viewport on top of live video? I’d like to see a copy of my animation on top of the live video. I have access to both a Nvidia 5000 with SDI out and a Matrox card.
Also how would I go about connecting an optical tracking system to control Motionbuilders virtual camera. Sorry I’m still pretty new to MB. Thanks, in advance.
Yes, you can use a hardware keyer when you pipe the HD SDI feed out from MotionBuilder. You can send fill and key information which will let you composite MotionBuilder’s 3D real time render over a live action plate. If you don’t require hires synched video and animation, you could try pluging in a USB camera which supports direct show, and display its feed as a plate inside MotionBuilder directly.
Talk with your mocap hardware vendor about the plugin they’ll provide for MotionBuilder which will let you stream live mocap data in. Once you have the optical mocap data, you can setup a rigid body constraint and drive a user created MotionBuilder camera.
