A looping visual with the wrong soundtrack length is the usual reason these videos feel unfinished — the music stops early, or gets cut off mid-bar. LoopVideo lets you upload your own audio, set the video's runtime to the track, and decide what happens if the video runs longer than the song.
Add your track
- Load your video clip and trim the section you want to repeat.
- In the audio panel, choose Uploaded audio and pick an MP3, WAV, M4A or OGG file.
- Press the match-length control to set the loop duration to the track's exact runtime.
- Export. The video loops for as long as the song runs and the uploaded audio replaces the clip's own sound.
When the video is longer than the audio
- Loop audio — the track repeats with a short seam fade, best for beds, ambience and instrumental loops.
- Play once — the track plays through and the rest of the video is silent, useful when the music is an intro sting.
- Play once and fade — the track fades out at the end instead of stopping abruptly, the safest option for songs with a hard ending.
Practical notes
- Set the video loop to a whole multiple of the trim length so the visual seam does not land awkwardly against the music.
- Instrumental and ambient tracks loop far better than songs with vocals, where a repeat is immediately audible.
- Only use music you have the rights to. Platforms mute or remove uploads that fail their rights checks.
Open LoopVideo to trim your clip, set an exact loop length in minutes and seconds, and export a high-bitrate MP4 up to 4K — in your browser, with no upload and no watermark.
Frequently asked questions
- Is the original clip audio kept?
- No. When you upload a track it replaces the clip's audio in the export. Choose the video-audio mode if you want the original sound instead.
- Which audio formats work?
- MP3, WAV, M4A and OGG decode reliably. If a file fails, re-export it as WAV or MP3.
- Can I make the video exactly as long as the song?
- Yes — the match-length control sets the loop duration to the uploaded track's runtime.
