AV Sync Fix at Mac App Store analyse

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. Its very fast. There is no need to export as another modified movie file. ■ The minimum storage space required 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. ■ Supported Formats - 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/audio files (e.g. Movies, TV Shows downloaded from iTunes Store or TV app) - Fragmented MP4 ■ NOTE! Please backup your data before using this app, just in case an unexpected error occurs.
