To present video frames of a video segment at a non-standard speed, a frame count is set to an initial value (204). For each video frame that is to be presented, a time offset relative to a staring time within the video segment is generated (208). The time offset may be generated by multiplying the frame count by two values, where the first value is a length of time for which each selected frame is to be presented to the user, and the second value is the presentation rate of the video segment relative to a normal presentation rate. A video frame within the video segment corresponding to the time offset within the video segment is selected and output for presentation (210, 212). The frame count is then updated (214), and the process is repeated for the next frame to be presented. |
