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.
