How to Remove AI Metadata From MP4, MOV and WebM Videos

Video files can carry more than the frames and audio you see and hear. MP4, MOV and WebM containers may also include creation times, encoder names, comments, chapters, attached artwork, location fields and provenance records such as C2PA. A platform can inspect those records when a video is uploaded.

Why deleting a few tags is not enough

Video metadata can live at several levels: the outer container, individual video or audio streams, timed metadata tracks and attached streams. A simple “remove title and author” operation can miss records elsewhere in the file. This cleaner maps only the primary video and optional audio stream into a new container without mapping source metadata.

How the browser video cleaner works

AI Label Remover loads a local WebAssembly build of FFmpeg. It reads your file in browser memory and stream-copies the primary video and optional audio into a fresh MP4 or WebM container. Source metadata, chapters, attached thumbnails and extra streams are not copied. The media streams are not recompressed, and your video is never sent to an upload endpoint.

Step-by-step

1. Open the AI Label Remover.
2. Select or drop an MP4, MOV, M4V or WebM file up to 200MB.
3. Keep the tab open while the local progress indicator advances. The first video also loads the FFmpeg engine.
4. Download the resulting -clean.mp4 or -clean.webm file.

What this does not guarantee

Remuxing removes file-level metadata carried by the source container and excluded tracks. It does not guarantee removal of an invisible watermark or data embedded in the copied video or audio stream, and it cannot prevent a platform from using classifiers, perceptual matching, upload history or an existing post record.
