Abstract
A method is described for encoding video. A video sequence is captured at a full frame resolution. Boundaries for an inner region are identified within frames of the video sequence. The video sequence is encoded at the full frame resolution into a bitstream. The bitstream includes a sub-bitstream which encodes for the inner region. Data is embedded within the bitstream. The data identifies the sub-bitstream within the bitstream. In one aspect, the data is a header specifying the inner region. In another aspect, the encoding estimates motion for pixels within the inner region based on pixels within the inner region.
