An MPEG4 modifier allows you to change the hidden details (metadata) of your video files, such as the title, author, creation date, and camera settings, without re-encoding the actual video. This process preserves the original video quality and takes only a few seconds.
Here is a step-by-step guide to changing video metadata using popular, free MPEG4 modification tools like FFmpeg (command-line) and MP3Tag or VLC (graphical interface). Method 1: Using a Graphical Tool (MP3Tag)
MP3Tag is a free, widely-used visual editor that supports MP4/MPEG4 video metadata. Download and open MP3Tag.
Drag and drop your MPEG4 (.mp4) video file into the main window. Click on the video file from the list to select it.
Edit the tags on the left-hand panel (Title, Artist, Year, Genre, Comments).
Click Save (the floppy disk icon) on the top toolbar to apply changes. Method 2: Using a Command-Line Tool (FFmpeg)
FFmpeg is the most powerful tool for this task because it modifies data instantly without re-rendering.
Download FFmpeg and open your computer’s Command Prompt (Windows) or Terminal (Mac/Linux).
Navigate to the folder containing your video using the cd command.
Run the modification command using this exact syntax:ffmpeg -i input.mp4 -metadata title=“My New Title” -metadata artist=“Author Name” -codec copy output.mp4
Press Enter to generate a new copy of your video with the updated metadata.Note: The -codec copy flag ensures the video is not compressed or downgraded. Method 3: Using a Media Player (VLC)
If you already have VLC Media Player installed, you can use it for quick, basic edits. Open the video in VLC Media Player.
Press Ctrl+I (Windows) or Cmd+I (Mac) to open Current Media Information. Type the new metadata directly into the General tab fields.
Click Save Metadata at the bottom right corner of the window. Important Technical Considerations
Backup your file: Always keep a copy of the original video before using a modifier, as incorrect editing can occasionally corrupt the file header.
Compatibility: Some older media players ignore custom metadata fields and only read standard tags like Title and Date.
Privacy: If you are sharing videos online, you can use these same steps to completely delete metadata to protect your location and filming date. If you want, tell me:
Which operating system you are using (Windows, Mac, or Linux)? Do you prefer a visual software or a command-line tool?
Are you trying to edit one video or bulk-edit many files at once?
