Spatial Media Metadata Injector
Spatial Media Metadata Injector is a free, open-source tool for examining and adding spatial media metadata in MP4 and MOV files.
What Spatial Media Metadata Injector is
Spatial Media Metadata Injector is a free, open-source tool for examining and adding spatial media metadata in MP4 and MOV files. It works with spherical video and spatial audio: the examine command prints metadata already in specified files, while the inject command saves a modified copy as a separate output file. Its stereo layout option supports mono, top-bottom, and left-right arrangements. Spatial audio injection requires a four-channel first-order ambisonics track using ACN channel ordering and SN3D normalization. The documented command-line tool must run with Python 2.7, and the project describes building a standalone graphical application with PyInstaller. The public GitHub repository includes specifications for spatial audio, spherical video, spherical video V2, and VR180 video formats, along with a license file. The tool is available for Windows, macOS, and Linux, and GitHub Issues are available for questions or issue reports. The Free plan costs nothing and covers metadata injection and validation for MP4 and MOV files.
Good
- Examines existing metadata and injects metadata
- Saves injected media as a separate output file
- Supports Windows, macOS, and Linux
- Repository includes spatial media format specifications
Watch out
- Command-line tool requires Python 2.7
- Spatial audio injection requires a specified ambisonics track
Who it suits
This tool suits people working with 360-degree video or spatial audio who need to inspect or inject metadata in MP4 and MOV files. Users of the documented command-line tool must be able to run it with Python 2.7.
Verdict
Spatial Media Metadata Injector provides metadata inspection and injection for supported spatial media files, with command-line and documented GUI-building options. Its Python 2.7 requirement and spatial-audio input specifications are important considerations.
