Abstract
Methods and systems for seeking to a non-key frame in a compressed video. The compressed video has a plurality of frames, each with a playback timestamp. At least one of the frames is a key frame. A selection of a non-key frame is received, and a temporally proximate key frame is identified. The set of frames between the identified key frame and the selected frame is played in a reduced time interval, and the selected frame is displayed as if it were a key frame.
