Disabling and enabling track in MP4 or QuickTime based media files with AtomBox Studio

This tutorial will demonstrate how to disable a track in existing MP4 or MOV compatible file with AtomBox Studio solution and then how to enabling the track back.

Back To Main Page

AtomBox Studio provides the ability to disable and to enable, previously disabled, media tracks. The function is useful, when investigating corrupted MP4/MOV files, which cause crashes or freezes in playback platforms. If the data corruption is on system/multiplex level it is possible to determine which of the tracks is causing problems during playback by disabling the tracks one by one.

1. Starting AtomBox Studio application and opening a MP4 media file.

All the tracks are located in the ‘moov’ atom/box on its root level. More information about each track type and parameters can be found on the right quick info panel.

2. To disable a track you need to select the track in the main tree-view and to select “Disable Track” either from the “Tools” menu or by right-clicking on the track and selecting the option from the pop-up menu.

The disabled track now appears in the ‘moov’ atom/box as a ‘free’ atom/box. The data in the ‘mdat’ atom/box is intact, but since there is no description available in the ‘moov’ atom/box.

3. The track can be enabled by selecting the previously disabled track atom and selecting “Enable Selected Atom/Box As Track” option either from the “Tools” menu or by right-clicking on the disabled track atom and selecting the option from the pop-up menu.

The atom/box is enabled back as a track along with all its internal sub atom/boxes.
