Overlay audio on video online
Overlay audio on video online
Upload a video and one or more audio tracks, choose the base clip, then adjust volume and start offset for every sound. The service mixes tracks with the original video audio or replaces it and saves the finished result as MP4.
Use the tool for voice-over work, background music, sound effects, comments, presentations and short clips without installing a desktop video editor.
