A computer-implemented method to synchronize video with beats in audio is described. Multiple video frames and multiple audio frames are displayed in a first and second bounded region, respectively, in a user interface. The multiple audio frames represent audio content that includes a periodic beat that is audible when the audio content is played. Input is received to associate one or more video frames with the multiple audio frames using a cursor. In response to the input, the first video frame is synchronized with a beat audio frame in the multiple audio frames. In response to a playback input, the first video frame is displayed in the user interface when the beat audio frame is played.
