  Encoding to stereo to mono drops volume, why?

  Posted by Shayne Weyker on November 2, 2007 at 4:47 pm

  Hi,

  I’m encoding a bunch of videos (shot on 32Khz DV) where the same dialogue is on the left and right track but at different levels, these are a stereo pair in the 32khz DV project. Rather than manually EQ the timelines I decided to encode a bunch videos to mono.

  The original audio source was two wired lav mics right next to each other, one going to L on the deck one to R.

  But I’ve found that when encoding that I lose a lot of volume in the final encoded file making it quieter.

  I’m not sure but I think that raising the levels on the timeline even a lot doesn’t seem to change the encoded output’s audio noticeably

  the output format from CS3 PPPro Media Encoder is a cusomized version of “Ipod, Large”
  .mp4
  h.264 baseline
  640×480
  32khz/128kbit aac audio
  ipod compatible

  Can anyone tell be the quick and easy way to get (at least though the encoder) L/R balanced and adequately loud audio when starting from audio that leans a bit right or left?

  Thanks for any help.

  Shayne,

  I don’t know how the Ipod export handles stereo tracks, I would assume it just mixes down the channels involved to mono, but apparently that was not the case.

  What I can offer you is the right workflow for your next edit 🙂

  Before you drop anything on the timeline (otherwise those option won’t be available to you), select all the clip the are recorded on separate channels, go to Clip > Audio Options:

  Then you can do either of these things:

  Break out to mono will give you separate mono channels in the project window itself.

  Or even better: Source channel mapping, and change that to mono. That will give you 2 separate mono channels on the timeline, so that you can pick the appropriate one if the other peaks.

  Cheers,

  Vince
