Standards for Capture

Best practices are always to capture at the highest qualities possible.  You can always compress and reduce file size/quality, but you can't go back and increase quality without re-shooting the entire event.

Archival:

Video: The best quality possible.  At this time, the standard that AMPS is using is a Motion JPEG 2000 capture.  The next level is an HQ XDCAM EX format (Full 1080p30).

Audio: Uncompressed (raw audio file)

pros:

  • the quality is very high

cons:

  • the file sizes are very large.  Motion JPEG 2000 is roughly 23 Gb/hour.  XDCAM EX is roughly 16Gb/Hour

For the web (MIT TechTV): capture footage at original quality and then compress/output to below settings

Standard:

  • video:
    • H.264
    • .mov/.mp4/.m4v
    • 480x270 / 480x360
    • 500kbps
    • 30fps short videos, 15fps long videos (30 min or more)
  • audio:
    • AAC
    • 32Khz
    • 64kbps
    • mono

HD/HQ:

  • video:
    • H.264
    • .mov/.mp4/.m4v
    • 480x270 / 480x360 or HD resolution (1920x1080, 1440 x 720 - recommended for shorter videos only since file size will be much larger)
    • 1000kbps or more
    • 30fps short videos, 15fps long videos (30 min or more)
  • audio:
    • AAC
    • 44.1Khz
