The processor may determine an average size of the plurality of I-frames. The average I-frame size may be based on a bitrate speed of the video file. The processor may retrieve a portion equal to the average I-frame size of from the beginning of each one of the plurality of chunks of the video. The processor may receive a begin trick play request of the selected video and initiate trick play of the selected video.
