  1. 1. Workflow Innovation A continuing revolution in the production process Starts: 11:00 Penny Paganuzzi
  2. 2. This Session General tutorial Not a product briefing Demonstration to follow using an example workflow Questions after the demo please
  3. 3. Past, Present and Future of Using IT infrastructure and technology to handle Audio/Video material
  4. 4. AV/IT History Late 20th Video tape used throughout Century Linear synchronous connections No metadata 2005 There are still gaps in the emerging AV/IT infrastructure Non-linear editing islands are common Tape to disk transfers incur time penalties 2008 Media acquisition possible in file format Many cameras support file-based transfers & proxies Full digital workflow with metadata now possible
  5. 5. Basic concepts : Streams Video tapes record streams Streams are uncontained and undefined Streams contain no metadata • except timecode Streams are transferred using point-to-point connections • Composite, component, SDI, AES/EBU, etc. Streams are transferred at play speed
  6. 6. Basic concepts : Files Files can contain metadata & A/V data • Names, dates, video format, identifiers, etc. Files can be transferred using IT connections at high speed • Ethernet, SCSI, Fibre Channel, etc Files can be stored on standard IT Hardware Breaks the link between format and media • Agreed file format used in any file-based media
  7. 7. Basic concepts : Metadata Data about data • Information about content Why is it important? • Allows easy searching, fast editing and postproduction • Allows re-purposing • Supports tighter rights management
  8. 8. Basic concepts : Metadata When and where is it captured? Does it flow through the entire production process?
  9. 9. Basic concepts : Manual & automatic metadata Acquisition metadata (auto) • Timecode, GPS position • UMID (Unique Material Identifier) each clip has unique ID Acquisition metadata (manual) • Essence mark : timecode, strings (32 characters) • Shotmark 1 & 2 (manual) • Scene change 1 (auto : luminescence) • Scene change 2 (auto : audio level) Additional Text (manual): • Names, notes, comments, etc.
  10. 10. Basic concepts : UMID Unique Material Identifier Number attached to a clip Uniquely identifies the clip from any other Extracted from many parameters • Date, time, machine serial number • GPS data, country code, company code, user code Specified in SMPTE 330M standard
  11. 11. Basic concepts : Proxies Low-res copies of video and audio material Highly compressed files Fast transfer over a computer network Fast searching, browsing, and editing Playable on standard computers with standard software • Windows Media Player, Real player, Quicktime May be used for emergency playout • Standard decoder back to baseband signal
  12. 12. • Scenes can be played back via thumbnail • Clip-lists enable simple in-camera edits
  13. 13. Sophisticated Thumbnail Operation • Quick Random Access • Arbitrary File Name • Expand and Chapter Search • Selected Clip Delete • Overwrite Protection Clip Operation Scene Selection (Cut-only Edit)
  14. 14. Introduction of non-linear editors Digitising required to ingest into NLE Editing is file based Editing includes metadata Final edit recorded back to video tape
  15. 15. From in the field
  16. 16. To High end Post-Production
  17. 17. And every level in between… Vegas Pro 8 Final Cut Pro And many others
  18. 18. Introduction of video servers Edits can remain as files • Servers can hold metadata • Servers can hold edit decisions and versioning Introduction of digital archives • Material & edits can be archived as files • Metadata can be retained in archive • More metadata can be added for better archive search/retrieval
  19. 19. Hybrid workflow: Introduction of non-linear editors Acquisition Production Delivery Streams Files Streams Camcorder Video Video Transmission Non- Tape Tape Linear Recorders Recorders Editor Camera Archive Video tape Digitising Linear Video tape or linear recording or linear connection to tape connection
  20. 20. Introduction of video servers Acquisition Production Delivery Streams Files Streams Camcorder Video Non- Transmission Video Tape Linear servers Recorders Editor Camera Archive Digitising Network Video tape File Transfer via Network transfer or linear Transfer to data tape connection

  23. 23. Target workflow Files used throughout • File based camcorders & recorders • File-based editing, storage & distribution • File-based archive and retrieval Automatic metadata added right from the start • All clips uniquely marked Consistent files and metadata throughout workflow • Agreed metadata standards Any new metadata adds to existing metadata • Nested metadata • Customised metadata
  24. 24. Target workflow Acquisition Production Delivery Files Transmission File File based Non- Video based camcorder Linear servers Digital recorder or camera Editor archive Network Network Network Network transfer transfer transfer Transfer/ Data tape
  25. 25. Using metadata in target workflow Acquisition Production Delivery Files Transmission File File based Non- Video based camcorder Linear servers Digital recorder or camera Editor archive …and here …and here Metadata added …and here …and here here…
  26. 26. Problems if metadata is not used properly Metadata is Inconsistent • Poor search performance Metadata not properly understood • Data models not compatible Islands of non-standard metadata • Re-keying required and lost information Metadata transfer not always easy • Re-keying required and lost information
  27. 27. Standardisation is important XML UMID Dublin Core
  28. 28. Flexible File Formats Material eXchange Format • Wrapper format, allows video encapsulation • Includes metadata • Used by a wide range of products from many vendors SMPTE 377M - 393M + EG 41 -EG42 See WWW.SMPTE.ORG
  29. 29. Partners in Standards BBC r&d
  30. 30. Supporting Products Workflow transformation requires: • Acquisition - Camcorders/Ingest Machines • Editing - NLE software for both SD and HD • Distribution - Networked production systems • Archive - Hard Disk, Optical Disc, data tape-based libraries • Media Asset Management Systems – Metadata/search for reuse
  31. 31. Sony Product Support for File-based workflows XDCAM HD : Optical file based (XDCAM disks) • Programme acquisition, high speed editing • XDCAM HD 422 • High Quality programme acquisition, high speed editing XDCAM-EX: Flash RAM based • Low cost, high speed, high quality
  32. 32. Sony XDCAM family Files recorded to disc or Flash card (SxS) Automatic metadata recorded right from the start Immediately in the IT domain XDCAM Discs can be ‘pre-loaded’ with planning data

  37. 37. Transmission Improvements A/V files can be played out directly from server Transmission files and rushes can be stored on data tape • Sony SAIT/LTO4 and PetaSite XDCAM CART option for direct disk playout
  38. 38. Archiving Data shelf-life and reliability improved (backups, RAID etc.) Proxy files can be incorporated into browse library (e.g. Blue Order Media Archive) High resolution e.g. MXF files can be stored in a hierarchical environment Additional Search metadata can be added for easy retrieval

  40. 40. Recent Challenges with Workflow Improvements Choice of digital Media • Optical disc or memory card • Capacity, cost, robustness Ease of use of editing software • Scary to new users? • Facilities bloat
  41. 41. Summary Capture to AV/IT Workflow can now be bridged • avoids playspeed ingest and re-keying File-based media allows storage of multiple A/V formats Metadata maintained throughout production flow allowing improved: • tracking • rights & asset management Programme production is quicker
