AtomBox Studio – The Must-have Tool For MP4 and QuickTime File Analysis
AtomBox Studio Pro analyzer provides a structural representation of the QuickTime, MP4, Fragmented MP4, 3GPP, 3GPP2 and Flash Video containers file format. A tree-view presents the detailed atom and box structure of the file. It also shows the inner hierarchy and full parameter list of atoms and boxes. A separate hexadecimal data preview is available, enabled for automatic file data positioning on tree-view atom/box selection.Along with the presentation capabilities, the AtomBox Studio can perform multiple operations on the supported containers such as container validation, demultiplex, re-multiplex, atom extraction and merging, atoms and tracks enabling and disabling, etc.
AtomBox Studio Pro also offers QuickTime and MP4 files verification and validation according to the Apple’s QuickTime File Format standard and the ISO/IEC 14496-12/14 standard. The currently loaded file in the AtomBox Studio Pro can be validated by selecting “Validation” from the “Tools” menu.
AtomBox Studio Ultimate is a product extension of the AtomBox Studio Pro. Along with the standard functionality of AtomBox Studio Pro, the extended product includes AVC/H.264 Video Validation and AAC Audio Validation Modules. The container validation as well as the audio and video elementary streams validation are now enabled. The HEVC/H.265 Video Validation is available as a separate purchase option. The elementary streams validation process is performed by on-the-fly demultiplexing and verifyication of all audio and video elementary streams subsequently. The Ultimate version of AtomBox Studio supports stream view of AVC/H.264, HEVC/H.265, VVC/H.266, AAC and AC-3 elementary streams.
The currently loaded file in the AtomBox Studio Ultimate can be validated by selecting “Validation” from the “Tools” menu.
Apart from the manual QuickTime and MP4 media validation provided in the AtomBox Studio Pro solution, Jongbel Media Solutions also provides automated QuickTime and MP4 media validation in its Media Validator solution.
The combined validation report output, containing the multiplex and all elementary streams validation information, can be exported into XML report file, having the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.

AtomBox Studio’s General Info
AtomBox Studio
All container errors, such as important atom/box absence, incorrect container structure or invalid header values, pointed as mandatory in the corresponding specification are output as Error Report. All container irregularities, which are not pointed as mandatory in the corresponding specification, but have unusual content are output as Warning Reports. Additionally there is a set of Informational Reports, which deliver more detailed information about the file being examined, such as the tracks format, media duration, moov and mdat atom/box positioning, etc.
AtomBox Validation preview
Each QuickTime and MP4 check can be disabled or enabled or set to another report type, such as Info, Warning or Error. The solution can be applied in wide variety of workflows and with many container format deviations due to its flexibility and customization ability.

The validation report output can be exported into XML report file, containing the full report information in standard XML format. This allows easy integration of the solution with any digital media workflow and further processing of the report information with any third party systems.
The validation takes only a few seconds for an average long and complex media file to be processed.
