Package Set
Import OV and VF folders, preserve revision lineage, and inspect compositions, reels, tracks, edit rates, encryption declarations, and package type.
Offline cinema package desk
CPL Proof
Resolve a complete OV/VF package set, verify declared files and digests, bind the CPL to a KDM screening window, and leave an inspectable operator handoff.
Package setImmutable OV and VF revisions
Dependency railLocal, external, missing, or failed
Screening gateCPL, KDM, time, and server target
Six exportsPDF, three CSV, JSON, and TXT
One inspection case, every package revision
Resolve the package set before ingest
CPL Proof keeps each folder import as an immutable revision, follows every composition track to a viable package supplier, and separates package integrity from screening readiness.
Dependencies
Resolve each CPL track to its local or external supplier and expose missing files, hash failures, duplicates, and unresolved VF links.
Verification
Review XML coverage, declared byte counts, supported SHA-1 or SHA-256 digests, cross-package dependencies, and screening findings.
Screening
Bind the chosen CPL to show time, lead and tail buffers, KDM validity, device metadata, and an expected server thumbprint.
Handoff
Freeze the case, operator, venue, drive, screening decision, findings, audit trail, and evidence for the next person.
Current version 1.1 interface
Designed for the projection desk
Portable evidence
Keep the decision inspectable
A result is useful only when another operator can see what was checked. CPL Proof exports package provenance, dependency resolution, findings, the complete case state, and a screening note alongside a readable PDF.
- PDFReadable package preflight report
- 3 CSVPackage inventory, dependency graph, and findings
- JSONVersioned audit snapshot
- TXTConcise screening handoff
Verification boundary
Clear about what a phone cannot certify
CPL Proof checks package XML, identifier relationships, file presence, declared byte counts, supported cryptographic hashes, cross-package OV/VF dependencies, reel timing, KDM targeting and validity, and an optional expected server thumbprint.
It does not decode MXF essence, validate JPEG2000 codestreams, verify XML signatures or certificate chains, decrypt content, emulate a cinema server, measure picture or sound quality, or certify playback. Complete a standards-aware desktop verifier pass, cinema-server ingest, and controlled screening before exhibition.
