System and method for multistage frame rate conversion. A method comprises receiving an incoming frame at a first frame rate, and determining whether a fault condition exists. The method also includes if the fault condition does not exist, toggling a write buffer pointer from a first frame buffer to a second frame buffer, and storing the incoming frame in the second frame buffer. The method additionally includes if the fault condition exists, determining whether a previously received frame was repeated, discarding the incoming frame if the previously received incoming frame was not repeated, and storing the incoming frame in one of the frame buffers pointed to by the write buffer pointer if the previously received incoming frame was repeated.
