Video Metadata Editor is a streamlined utility for fixing and updating common metadata tags inside a video file. Upload a video and the tool probes the container and video stream, then reads existing metadata such as title, artist/creator, genre, year/date, and a description-like comment. You can edit these fields directly in the browser, preview the detected file information, and then click Update metadata to export an updated MP4 that includes your new tag values. The backend writes metadata using FFmpeg in a deterministic, stateless request so processing is fast and the UI stays responsive. If direct stream remuxing is not possible, it falls back to a safe MP4 export path for compatibility. An optional AI Assistant can suggest consistent tag values using the filename and detected tags; AI only suggests and nothing is applied until you explicitly update metadata.
Note: AI can make mistakes, so please double-check it.
Fix title, creator, genre, year, and description-like notes.
Apply
Write updated metadata to a new MP4.
Suggest consistent tags from the filename and detected metadata. You control what gets applied.
Common questions about this tool
Upload your video, wait for the tool to detect the container and metadata tags, edit fields like title, creator, genre, year/date, and comment, then click Update metadata. The tool downloads an updated MP4 with the new metadata applied by the backend.
The editor focuses on common fields that FFmpeg can write across common containers: title, artist/creator, genre, date/year, and a comment or description-like field. Other specialized tags may not be exposed in this simplified interface.
The backend first tries a fast remux/copy path to keep encoding unchanged. If that fails due to container/codec limitations, it falls back to a compatible MP4 export path for reliable results.
Some containers store metadata differently or ignore keys they do not support. If a field is empty, the tool omits it from the output update; if you need strict control of every tag, consider a dedicated metadata editor for your exact container.
When you click Suggest tags with AI, the tool sends your filename plus a compact summary of detected metadata to a secure backend AI endpoint. The AI returns suggested values and a rationale; you can review and edit them before applying updates, and the video is not changed until you click Update metadata.
Upload your video to the Video Metadata Editor, wait for the tool to detect the file and existing tags, then update fields like title, creator/artist, genre, year/date, and comment. Click Update metadata to download a new MP4 that includes your changes.
The backend first tries a fast remux/copy path so the video streams stay unchanged when possible. If direct copying is not supported for your input, it falls back to a compatible MP4 export path.

Some containers store metadata differently or ignore certain tag keys. Also, if you leave a field blank, the tool omits it from the update rather than forcing an empty value.
When you click Suggest tags with AI, the tool sends your filename and a compact summary of detected metadata to a secure backend AI endpoint. The AI returns suggested values and a rationale, and you still apply the update manually by clicking Update metadata.

Video Metadata Editor helps you clean up and standardize the metadata inside a video file without using a full nonlinear editor. It’s designed for the most common frustration after uploading or downloading media: missing titles, incorrect creator names, inconsistent genre labels, and descriptions that don’t match your intended upload information. Instead of guessing where the metadata lives, you upload a file and the tool probes the container and stream details, reads the existing tag values, and presents a focused set of fields you can edit right away.
The tool then exports a new MP4 containing your updated metadata, so your video remains easy to manage in media libraries and easier to share in workflows that display titles, creators, genres, and descriptions.
The core objective is to provide a fast, deterministic “upload → edit tags → download” pipeline for video metadata fields that FFmpeg can write reliably. This solves the common pain point of metadata inconsistencies by making tag editing simple, repeatable, and server-driven, while keeping the browser UI responsive.
This simplified editor focuses on a practical subset of metadata fields. It reads what’s available from the uploaded container and lets you update the following values:
| Field | Meaning | Notes |
|---|---|---|
| Title | Video title shown in players and libraries | Mapped from the existing container tag when available |
| Artist / Creator | Who created or authored the video | Commonly stored as “artist” or similar fields |
| Genre | Category label for organization | Useful for playlists and search |
| Year / Date | Release year or a date string | Works for “year-like” metadata and date formats |
| Comment / Description | A longer text description-like field | Often corresponds to container comment fields |
The must-have promise of Video Metadata Editor is accurate time-independent metadata rewriting: it updates titles, creators, genres, years/dates, and description-like comments in a consistent “single output MP4” result. That makes it useful for workflows like “fix metadata after download,” “standardize a library,” and “prepare a cleaner upload package” without requiring editing the video content itself.
The AI Assistant is optional and must be triggered by you. When you click “Suggest tags with AI,” the tool sends your filename and a compact summary of detected metadata to a secure backend AI endpoint. The AI returns suggested tag values and a short rationale so you can review and adjust them before applying updates. The video is not changed until you click “Update metadata.”
For practical compatibility, the backend exports an updated MP4. It first attempts a fast remux/copy path to avoid unnecessary re-encoding. If direct stream copying is not possible for your specific input, it falls back to a compatible export path so the result stays playable in common MP4 environments.
If you enter metadata that a container does not support, the output may ignore certain keys. This is why the editor intentionally focuses on fields that are widely writable across MP4-style metadata workflows.
This tool is designed for searches such as video metadata editor online, edit MP4 title and artist, update video description and genre, creator name fixer for videos, and how to change video metadata tags after download. It also supports intent-style use cases like standardize video tags for media libraries, create consistent naming metadata from filename patterns, and prepare a trimmed or converted video package with matching title and description fields.
Common editing scenarios include cleaning up “untitled” uploads, correcting creator spelling after renaming files, aligning genre labels across a playlist, and making the description reflect what viewers actually receive. If you manage many files, you can repeat the same process with different videos and keep your metadata organized in a predictable way. This helps reduce the manual work of opening every file in a separate tool just to update a few fields.
After updating tags, you can continue editing metadata-aligned transformations with related tools such as Audio Metadata Viewer, Audio Metadata Editor, Video Cropper, Video to GIF, and Audio Cutter. These tools help you prepare a final asset set where titles, creators, and descriptions match the media you share.
