During the 2014 Montreux Jazz Festival, an experiment was conducted to aquire the concerts in an uncompressed HD “tapeless” format. It was an important step to implement an effective acquisition workflow at EPFL. As a result the data management workflow could be set up accordingly.
There are three advantages to this process. The first removes the need to transfer data at a later stage. The second ensures the automatic safeguard of the recordings due to bit-spreading technology on the hard disk system. The third is to get experience in uncompressed tapeless aquisition for HD tapes ingestion of MJF archives.
HD specifications for one video stream:
- YUV 10 bit 1920 x 1080 resolution
- 50i and 60i
- Bit rate approx. 150 MB/s (1.2 GB/s)
- 1 hour of HD requires 540 GB of storage
Two HD video streams for three halls includes:
- One ISO (recording of a fixed camera non-stop throughout a performance)
- One programme (recording of a real-time edited version of a performance)
6 HD streams per night for 5 hours per evening:
- 540 GB x 5 = 2’700 GB (one stream in one hall per night)
- Two streams per hall – 2’700 GB x 2 = 5’400 GB per night for one hall
- Three halls in totals – 5’400 GB x 3 = 16’200 GB one night for all halls
- For the whole festival 18 nights – 16’200 GB x 18 = 291’600 GB
The storage needed to record 6 streams of uncompressed HD video direct the HGST Active Archive hard-disk system is 291.6 TB for one complete edition of the Montreux Jazz Festival.
