Abstract
Video editing and video playback utilizing a render-ahead queue for storing rendered video frames. The render-ahead queue facilitates the smooth playback of video in forward and reverse timeline direction, avoiding video glitches that occur when video frames are rendered at a rate that is less than the timeline rate of the video file. Embodiments of the present invention also include the use of a graphics processing unit in conjunction with the render-ahead queue to further ensure smooth playback of video.
