Abstract
A method of encoding video is presented in which multiple groups of pictures (GOPs) are formed and encoded in parallel threads. Each encoded GOP has an initial I-frame followed by a series of P-frames. Each I-frame is deflicker coded with a first derived no flicker reference from the nearest coded frame of a preceding GOP and, the last P-frame in the series of the preceding GOP is deflicker coded with a second derived no flicker reference from the deflicker coded I-frame.
Claims10
A method of encoding video comprising the steps of:
- forming multiple groups of pictures (GOPs);
- beginning multiple encoding of parallel threads of GOPs, each having an initial I-frame followed by a series of P-frames;
- deflicker coding each I-frame with a first derived no flicker reference from the nearest coded frame of a preceding GOP;
- and,
- deflicker coding the last P-frame in the series of the preceding GOP with a second derived no flicker reference from the deflicker coded I-frame.
