A method implemented by an apparatus for video transcoding comprising receiving video data intended for encoding, splitting the video data into a plurality of segments of appropriate sizes to enable distributed encoding by a plurality of video transcoders, obtaining rate control information for each of the segments by calculating related video statistics for each of the segments with subsequent segments in a determined time period, calculating an assigned bit rate to each of the segments based on the obtained rate control information, embedding the assigned bit rate to each of the segments, and forwarding the segments to a plurality of corresponding video transcoders, wherein the embedded assigned bit rate in each of the segments is extracted by the corresponding video transcoders to perform video rate control and enables the video transcoders to improve video quality and reduce rate fluctuation when encoding the segments.
