An audio-video system and method employs a dual-control interface for directly controlling the play speed of a video track while switching among a plurality of audio tracks independently of the video. The dual-control interface enables the user to adjust the play speed of the video track to match or synchronize with the tempo of a selected audio track at any point in time. The video speed and audio selection commands can be recorded as a file or on disk along with the underlying video and audio resources for playback or editing on PCs or game consoles. An Internet-enabled version can connect to streaming audio and/or video resources from Internet websites, for play on wireless mobile devices or Internet browsers. An Auto Beat feature may be used to automatically detect the beat of a currently selected audio track and convert it to the video track play speed. The audio-video system is particularly suitable for making personally editable music video and/or playing video games, audience participation (karaoke) games, and the like.
