Audio-Video Separation: Split Video and Audio Tracks in One Click, Fully Lossless
Split any video into independent video and audio tracks: extract background music, voiceover narration, or clean visuals — the separation never re-encodes, so output is fully lossless. Reuse the extracted audio in other remix projects, re-dub the silent video right away, and give every piece of footage a second life.
Download AIMIXSådan virker det
Built-in audio often gets in the way: to re-dub live-action footage you first need to strip the original sound, and to reuse a BGM you hear in a video you have to pull the audio out. Audio-Video Separation splits any video into independent visual and audio tracks in one click — the split is lossless with no re-encoding, the picture stays exactly as sharp as before, and the audio is preserved as-is. Once separated, strip the original sound, swap in a new voiceover, or extract the BGM, and combine however you like.
Split in one click
Click Separate and the video is split into an independent video track and audio track: no re-encoding happens, so both picture and sound keep their original quality.
Use each track separately
Re-dub or re-score the silent video track; store the extracted audio track (BGM, voice) in your library and reuse it in other remix projects.

Footage reuse: turn original-sound footage into a narrated version
Best for: e-commerce live-action, vlog footage · original-sound footage that needs new narration
结构Workflow: live-action video → separate into a silent video track → re-dub and add subtitles → remix into a finished video
- Strip original audio in one click
- Lossless picture with no re-encoding
- Audio track kept separately for reuse
Freshly shot footage comes with ambient noise and on-site chatter that makes raw cuts feel messy. Run it through Audio-Video Separation first to get a silent video track with quality identical to the original; then add a voiceover generated from your Script Management copy plus automatic subtitles, and a narrated version takes shape. Do not toss the stripped original audio either — it can occasionally double as behind-the-scenes material.
Common ways to use the separated tracks
Each of the two tracks has its own destination:

We recommend archiving the BGM and ambient sounds you extract most often in one place, gradually building an audio library of your own.
Behold kontrollen over klippet
Lossless split without re-encoding
The separation never re-encodes, so picture quality stays identical to the original footage.
Batch processing saves manual work
Separate multiple clips in one batch — no more exporting and re-importing one by one to strip audio.
Parts flow straight into remixes
The separated video and audio tracks go directly into your library and storyboard groups, powering derivative creations.
Ofte stillede spørgsmål
Does separation lose video or audio quality?
No. The split is lossless with no re-encoding, so both picture and sound keep their original quality.
What format is the extracted audio?
It is pulled directly from the original audio track, so the format matches the source footage — no transcoding needed.
Can it separate BGM from the voice?
Audio-Video Separation only splits the picture from the audio track; to further split vocals from the instrumental, use it together with the voice separation features.
Does it support batch processing?
Yes. Multiple videos can be separated in one batch, and results are saved to your library automatically — ideal for footage pre-processing.
Can I put the original audio back on a separated video?
Yes. Separation only takes the tracks apart; the original audio stays in your library and can be re-combined at any time.
Does separation consume AI credits?
Audio-Video Separation runs as local processing and does not consume AI analysis credits; if you stack AI capabilities such as voice separation afterwards, they are billed by their own rules.
