Verify the cinema composition that will enter the show

Identify the composition rather than only the delivery folder

DCI's approved Digital Cinema System Specification version 1.4.4 distinguishes composition playlists, track files and show playlists. A composition identifies how the relevant media forms the presentation; an exhibitor's show playlist can combine advertisements, trailers and films. This lesson uses those concepts, not a claim that every cinema deploys the same system version.

Ask the mastering or distribution provider for a readable identity mapping from the approved commercial to its composition reference. Include language, duration, local end frame and intended screen format in that mapping. A folder title alone may be ambiguous when a delivery contains several versions or an update relies on earlier material. Keep the marketing approval connected to the exact composition the exhibitor is expected to select.

Separate received, ingested and ready to select

Have the provider describe which delivery receipt proves that the files arrived and which evidence confirms successful ingest and required dependency availability. Ask the operator to identify incomplete, corrupted or unsupported packages through its normal tools. Do not ask marketing staff to rename internal package files or edit composition metadata as an improvised repair.

Confirm who owns any remastering or normalization step. Brightfish's Belgian advertising specifications state that even advertiser-supplied DCPs are remastered for its naming and format requirements, illustrating why the file sent by the agency may not be the final distributed package. Obtain the final identity mapping after that process and review any relevant approval preview. A transfer receipt and an approved source video are useful records, but neither proves the final composition is available on the intended screen system.

Check auditorium and time-dependent readiness

Ask the exhibition owner to confirm that the selected composition is appropriate for the intended auditorium and that any applicable playback authorization covers the actual test and exhibition windows. DCI 1.4.4 describes validation of composition playlists and, for encrypted material, the relevant key-delivery conditions. Not every advertisement is encrypted, so first establish whether this dependency exists.

Record only a non-secret status or reference in the campaign worksheet. Never place actual keys, credentials or sensitive authorization payloads in a training fixture, shared marketing sheet or general support message. Have the authorized technical parties manage those materials through their approved secure process. If a screening moves to another auditorium or date, ask them to recheck readiness instead of assuming a successful test transfers automatically.

Accept the selected presentation in context

Arrange the supported approval screening or exhibition check with the operator. Verify that the selected composition shows the correct language, offer, end frame and complete beginning and ending, and that it returns cleanly to the intended sequence. Let qualified cinema staff assess presentation and system requirements. A desktop viewing file can help identify received assets without reproducing the auditorium experience.

Record the actual scope of acceptance: which composition, screen configuration and test window were observed, and which remaining locations depend on the distributor's verified process. Do not label a sample screening as direct evidence for every booked performance. After a revised cut, repeat the affected identity and ingest checks. The campaign is ready when the intended approved composition can enter the correct show under the required conditions, not merely when a large upload reaches one hundred percent.

Make the reasoning concrete.

A fictional museum supplies two cinema versions with different local end frames. The distribution folder arrives, but the operator has selected the older composition and the proposed test occurs outside the authorization window for an encrypted version.

The museum asks the operator to correct the selection and confirm the applicable test conditions. Its worksheet records status references only, never key material, and distinguishes the sample screening from all campaign performances.

Take the questions into your next brief.

Use these prompts in your own notes. Nothing is submitted from this page.

1. Composition

   Which exact composition represents the approved language and local cut?

2. Ingest

   What confirms all required material is available, not merely transferred?

3. Transformation

   Did the distributor remaster the supplied package and change its identity?

4. Readiness

   Are screen compatibility and any applicable playback window confirmed by the operator?

5. Observation

   Which composition and exhibition conditions were actually tested?

Watch for the wrong conclusion.

• Treating a folder name as a unique approved composition.
• Equating completed transfer with successful ingest and selection.
• Copying actual keys or authorization payloads into campaign worksheets.
