AtomBox Studio

AtomBox Studio 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, showing the inner hierarchy and full parameter list of the 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.

The supported file formats can contain a wide variety of different video coded streams: MPEG-2, MPEG-4, AVC/H.264, Animation, DV, MJPEG; still graphic formats: TIFF, PICT, JPEG; and audio streams: PCM, AIFF, AAC.

AtomBox Studio in Dual Mode:

AtomBox Studio Pro is a product extension of the standard product edition. Along with the standard functionality of AtomBox Studio, the extended product 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. AVC/H.264 video validation, MPEG-4 video validation, MPEG-2 video validation and AAC audio validation modules are available as separate options.
