摘要：
There are provided methods and apparatus for efficient first-pass encoding in a multi-pass encoder. An apparatus includes a multi-pass video encoder for performing a first-pass encoding of input image data for at least one picture by sub-sampling at least a portion of the input image data prior to the first-pass encoding. The sub-sampling is at least one of spatial sub-sampling and temporal sub-sampling.
