Abstract
Un codificador de video utiliza información de movimiento previamente calculada para codificación inter-marco para lograr velocidad de cálculo más rápido para compresión de video, En una aplicación de velocidad de bit múltiple, la información de movimiento producida por la estimación de movimiento para codificación intermarco de una corriente de bit de video comprimida a una velocidad de bit se pasa a una codificación subsecuente del video a una velocidad de bit más baja. El codificador de video elige utilizar la información de movimiento previamente calculada para codificación de inter-marco a la velocidad de bit más baja si no se cambia la resolución de video. Un pre-cálculo de información de movimiento de núcleo múltiple produce información de movimiento antes de codificación al dividir la estimación de movimiento de cada intermarco para separar núcleos de CPU.
