HD Capture

Capturing in real-time approx. 1’700 hours of audio-visual content from the Montreux Jazz Festival archive recorded in High-Definition (HD) video.

The audio-visual acquisition from HDCAM tapes takes place at EPFL. This includes footage from the Montreux Jazz Festival in 1991, 1992, 1993, 1997 and from 2003 to date. When the 1991 Montreux Jazz Festival was recorded in HD it was considered a breakthrough in technology and world first for a music festival.

HD tapes contain the following uncompressed digital signal:

  • YUV 10 bit 1920 x 1080 resolution
  • 50i and 60i
  • Bit rate approx. 150MB/s (1.2 Gb/s)
  • 1 hour of HD equates to 540GB

Uncompressed video and audio streams are captured via a dedicated acquisition AV card. A quality control of the digitized content then takes place. Broadcast MXF and preview formats are then generated from the original file automatically. 

In addition to video and audio, SMPTE time-code is also captured to ensure synchronization with additional media streams or for post-production. Time-code is composed of time and frame information laid out in a precise order.
