Abstract:
Rate control is provided in a two-pass encoder. A first encoding pass is performed to encode an input video sequence. Coding statistics for the first encoding pass are collected. Target coding parameters for a second encoding pass are calculated based on the coding statistics for the first encoding pass. The second encoding pass is performed to encode the input video sequence at a constant bit rate (CBR) using the target coding parameters to form a second pass encoded stream.
