Abstract: Encoding of a video file includes determining a plurality of scenes associated with a video file, and determining at least one group of pictures (GOP). Starting sequentially from a beginning frame of the video file, the system identifies a first GOP having a first encoding error characteristic. The system changes a bitrate allocation setting from a first setting to a second setting based on the encoding error characteristic. The system identifies a second frame having a second encoding error characteristic, and changes a second bitrate allocation setting from the second setting to a third setting based on the second encoding error characteristic. The system generates an encoded video file that includes an encoded plurality of scenes.
