Patent ID: 8914725

Claim:
A method for providing digital video effects in live broadcast video production, the method comprising: providing a system having digital video effects (DVE) functionality and graphics modeling functionality; receiving live video input into the system; mapping the live video onto at least one virtual surface of a graphics model having at least two dimensions; providing an Application Programming Interface (API) for identifying and accessing elements of the graphics model; presenting the elements of the graphics model to the user as user controllable DVE parameters, wherein the DVE parameters are bound to the elements of the graphics model by the API such that manipulations to the DVE parameters cause the API to access the graphics model elements and make corresponding manipulations to the graphics model elements; presenting desired positions or states of the user controllable DVE parameters as key-frames in a timeline to form live broadcast video effects; interpolating intermediate values of the user controllable DVE parameters from key-frame to key-frame to produce a video output signal and a key using the graphics model in response to user adjustment of a user controllable DVE parameter; and providing the video output signal and key to a live video production switcher.
