3 What is XDCAM?

4 What is Professional Disc? New recording Medium similar to size and shape to CDs and DVDs Designed by Sony, based on Blue-Violet Laser technology. Can only be used with XDCAM equipment Format independent

5 Professional Disc Features Non-linear Medium High-Capacity and High Transfer Rate Disc Non-Contact Recording and Playback Format Independence Highly Resistant Against Heat and Shock Thin and Lightweight

6 Professional Disc Partners Sony Maxell TDK Fuji

7 What is Proxy? Low Resolution Copy of Recorded Clip. Video =1.5Mbps, Audio = 64kbps/ch Good for Fast File Transfer : Up to 50x Real time speed Quick Ingest and browsing Small capacity occupation of the HDD Good for Laptop PC or Field operation (Off-line Edit) Remote Browsing via Internet Browse purpose for Archive Good enough for emergency transmission.

8 What is Metadata? t Data about the recorded data Type of Metadata RealTime (RT) Metadata (Frame information): Timecode, UMID, GPS position, etc. Non-RealTime (NRT) Metadata (Clip Information): LTC Change Table, UMID Change Table, Essence Mark Table, Creation Date, Text Description, etc Disc Metadata: Disc Title, Disc ID, Date Initialized, etc Proxy AV Data: MPEG-4 Video and Audio Data, etc * Shot Mark is like a bookmark for video file.

9 What is? The Gateway to IT-Based Platform Material exchange Format The basic objective of the MXF file format is the exchange of program material in IT-based environments An interchange file format A flexible wrapper for Video, Audio and Meta-data. t A compression, network & operating system independent file format A rich metadata aware file format A stream-able file format with AAF & SDTI compatibility

10 The Inter-Island Format

11 Types of? OP-1A (Most Vendors including XDCAM) OP-Atom

12 What do broadcasters want from a Medium? 1. CAPACITY: Recording time 2. RELIABILITY: Scratches, weather, shocks 3. LOW COST: Tape 4. PORTABILITY: Size, weight, label, 5. Works across the ENTIRE production chain Professional Disc maintains the benefits of tape with its high capacity, small size, low unit cost and ruggedness

13 Capacity Recording Time 23.3GB 50GB 50 Mbps 43 min 95 min 35 Mbps 60 min 145 min 25 Mbps DVCAM & MPEG HD 90 min 190 min 18 Mbps 120 min 250 min

35 Problems with present workflows Mixture of technologies slows workflow. Reasons :- Mix of linear & non-linear, synchronous & asynchronous. Acquisition tapes (rushes) are converted to files (digitized). i i d) Material transferred on tape and via IP. Final programs sometimes converted back to linear tape. : Workflow 35

36 Problems with present workflows Organization of material is often difficult. Clips and segments difficult to find on tape. Time wasted searching for material. A lot of important material may go unnoticed. Reasons :- Inconsistent use of metadata. Use of metadata not properly understood. Islands of non-standard metadata. Metadata transfer not always easy. : Workflow 36

37 The XDCAM workflow features All XDCAM material is stored as files. All XDCAM clips are recorded in the camcorder as files on disk. Lo-res AV proxy is also recorded to disk automatically. Metadata a added at source. All XDCAM clips have metadata added automatically in camcorder. Metadata includes dates, times, labels, markers, thumbnails, etc.. : Workflow 37

38 The XDCAM workflow features Metadata is consistent throughout production workflow. Same S metadata t recorded d in camcorder is used in editing. Metadata is retained for all final edits as well. Scene selection data can reside on disk with material. This data can be made to play only selected clips in the order they were selected. : Workflow 38

39 Advantages of XDCAM workflow Low media running costs. Using Professional disk keeps media costs similar to tape. Media can be lent, borrowed and stored with impunity. A shoot can use extra disks without impacting costs. Fast operation. Archive can hold everything as a series of files. Hi-res and Lo-res files, EDL s, final program files and metadata. Searching through the archive can be done via metadata. : Workflow 39

40 Cost of ownership Low cost media. Disks can be re-recorded at least 1,000 times. Disk/data shelf life at least 50 years. 7 years warranty offered on all XDCAM products. Worry free warranty on critical mechanical parts. Cover free replacement of the optical drive. Including the laser, seek motor and disk drive motor. End-of-life and manufacturing defects.
