SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 OVERVIEW IMF PROCESS MASTERING USE CASE VERSIONING USE CASE SPE IMF REQUIREMENTS
SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 OVERVIEW • IMF is envisioned as a file-based Mezzanine Master Source which would serve a similar function as the HD Video Master does today at the front end of the client deliverable chain, with additional benefits. • Use IMF to ingest content into to our internal Distribution Backbone (DBB) • Send to our servicing vendors as their source to service client orders • IMF essence should be the at the highest quality level necessary to meet and exceed any client deliverable that is envisioned for the foreseeable future. • IMF itself is not envisioned as a client deliverable, all deliverables would be made via transcoding or other process to client specs. • IMF with uncompressed picture may be utilized for internal archiving in the future.
SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 IMF PROCESS IMF is envisioned as an additive process: • A “Base” IMF is created of the original version of the program that contains: • O.A.R. picture • Native language audio in 5.1 and Lt-Rt (and 7.1 if applicable) • Music and Effects and M+E optional material in 5.1 and Lt-Rt (and 7.1 if applicable) • Original subtitled text • CPL • OPL “Base” that contains content specific preferences (TBD) • Additional “Partial” IMF’s are created as needed and as material becomes available, and contain only: • Unique, additional or substitute content • CPL that plays content from base IMF and partial IMF as needed to create the intended program • OPL, inherited from “Base OPL” and modified as needed
SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 IMF PROCESS • Examples of additional IMF’s: • Additional picture resolutions • Foreign Localized • Alternate Cuts, e.g. Unrated, Director’s Cut • TV/Airline Versions • IMF’s are stored internally and at servicing vendors • Each new partial IMF is added to the storage, and the stored content directory for that title grows accordingly. • If a complete IMP is required, then all applicable essence is placed in the package from the base IMF and the partial IMF. • To service a client order: • OPL for requested version is utilized to call the CPL for that version, which in turn calls the essence to be played from the storage • CPL plays the program content • OPL is combined with client preferences to create output (TBD)
SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 MASTERING USE CASE • It is envisioned that at the start, the mastering process will create separate picture files for each of required resolutions e.g. 2.40. 1.78, 1.33 • The O.A.R. picture file will be in the “Base” IMF • Other picture resolutions will be in “Partial” IMF’s • In the future, we will want to allow the IMF to have much higher resolution picture essence and utilize metadata and dynamic metadata to obtain the desired resolution
SONY PICTURES IMF USE CASES PRESENTATION TO SMPTE 35PM50 WG 2011-05-10 VERSIONING USE CASE • Versions will be created as partial IMF’s • After the approved version is created in a workstation, the unique items are output to a “versioned” partial IMF. • The versioned IMF’s are stored with the base IMF and other partial IMF’s • To play the complete version, the OPL for the requested version is utilized to call the CPL for that version, which in turn calls the essence to be played, which will be from the base IMF and the versioned IMF. • If a complete versioned IMP is required, then all applicable essence is placed in the package from the base IMF and the versioned IMF.
