Tranquillity Base > AV Sync Fix

AV Sync Fix allows you to fix movies that are out of sync audio/video simply by dragging the timeline or in detail by entering numerical values.

The app does not edit actual media sample data. It edits time-mappings. You can immediately see the effect of the fixes and overwrite it without loss of audio/video quality. It's very fast. There is no need to export as another modified movie file.

NOTE!

• When you open a movie file, the app copies it to the storage of your Mac as a temporary file for editing. The app needs available storage size more than twice as much as the file size. Copying may take a few minutes depending on the file size. The temporary file will be deleted when you close the main window or quit the app.
• Please make a backup of your files before using this app.

• QuickTime Movie (mov)
• MP4 file (mp4, m4v)

But the app cannot open/play the following files.

• Files which QuickTime Player cannot open
• Files which require any conversion or codec components in QuickTime Player
• Protected video files (e.g. Movies, TV Shows downloaded from iTunes Store or TV app)
• Fragmented MP4
