Frequently Asked Questions
- Can I reverse an MP4 without re-encoding?
- Reversing always requires re-encoding because the frames must be read and written in opposite order. The tool uses libx264 at your chosen quality setting. Choose 'Best' quality to minimize any quality loss.
- Does reversed audio sound weird?
- Yes — reversed audio has the same waveform played backward, so speech becomes gibberish and music sounds surreal. For music videos or talking-head clips, toggle Keep Original Audio to keep the soundtrack forward while only the video plays backward.
- What's the max MP4 file size I can reverse?
- Our free tier handles typical MP4 files comfortably. For files up to 10GB, upgrade to a paid plan. Processing time scales with video length, not just file size.

- Can I reverse a portion of an MP4?
- This tool reverses the whole MP4. To reverse just a segment, use our cut video tool first to trim to the segment, then run that clip through the reverser.
