Quality Control Overview
Our quality control (QC) workflow leverages both automated and manual processes to ensure that digital assets meet our specifications. We perform automated QC on 100% of our deliverables, and manual QC on approximately 10-15%.
Our workflow incorporates the following open source tools:
- Ajv: an open source JSON schema validator
- BagIt: an open standard specification for packaging digital content; bagit-python is a commonly used implementation
- FLAC Utility: an open source tool for lossless compression / encoding / decoding of audio files to the Free Lossless Audio Codec
- Isolyzer: an open source tool used to verify the size of ISO 9660 images against Volume Descriptor fields
- MediaConch: an open source specification conformance checker which uses MediaInfo
- mpv: an open source, cross-platform media player
- QCTools: a software tool that helps users analyze and understand their digitized video files using audiovisual analytics and filters
- RAWcooked: an open source tool for lossless compression and reversible encoding of DPX image sequences into Matroska
