  HD Audio Codec, and DSLR Video Files

  Posted by Phil Radelat on September 23, 2013 at 6:07 am

  I’ve been under the impression that HDV and AVCHD video use some kind of MP3 variant as a codec for audio when recording. I’m recording HD video with a pair of Nikon DSLRs (D600 & D5100), as well as a little Canon S110, and notice that the MOV files generated show their audio to be uncompressed.

  I was kinda surprised about this, but I was further baffled that when I made a project in Premiere Pro CS6, using the default DSLR 1080 24P sequence setting, it exports an MPEG file that has compressed audio. I click on “match sequence settings” when exporting the sequence out in PP.

  So I suppose I’m asking two questions here, the first is does HD footage, whether it be HDV or AVCHD, normally record uncompressed audio? If so, and apparently so in my case considering all three cameras appear to show uncompressed audio when I view the file details, why does PP output a file to supposed “DSLR video” specs with compressed audio? To add further to my confusion, the audio output spec in the PP export window, when “match sequence settings” is checked off, declares the audio to be UNCOMPRESSED.

  Any info on this would be appreciated, thanks.
