  Audio lost after converting .avi file to mpeg dvd

  Posted by Cecilia Ruiz-smith on August 16, 2011 at 3:11 pm

  Hi, not sure where to post this question. I used after effects to render my movie render settings: dv settings, output: lossless

  the AVI file plays fine with the audio and the images intact but after I convert it to MPEG2 DVD using adobe media encoder, everything comes through except the audio. The movie contains both mp3 and wav files.

  settings I used in media encoder: format: mpeg2-dvd, preset: match source attributes. export video checked, export audio checked, I kept the audio format settings: audio format: pcm (codec: pcm audio)

  max render quality, checked.
  =========
  Movie looks good but my audio is gone? Why am I losing the audio track? Please help! Thanks you

  Hi Mr. LaRonde

  I converted the mp3 sound files into wav and added them to my movie. Exported from ae with the same settings,then converted the .avi into mpeg dvd using adobe media encoder. The audio is still gone. What else could I be doing wrong?

  Muxed? I’ve never heard that term before but I always love learning new stuff. I’ll try your suggestion right away and see what I come up with. If it turns out that the audio got muxed, what would be the next step?

  thanks again for helping me out.

  Hi, I’m not sure what to look for here but here’s the stream info from the mpeg streamclip software:

  Stream: MAINtimeline-customAVI.m2v
  Path: K:staffcrsCRSWEB_GRAPHICSRESCO PROJECTMovie testsMAINtimeline-customAVI.m2v
  Type: MPEG elementary stream

  Duration: 0:00:25
  Data Size: 19.03 MB
  Bit Rate: 6.37 Mbps

  Video Tracks:
  224 MPEG-2, 720 x 480, 16:9, 29.969999999999999 fps, 7.00 Mbps, lower field first

  Audio Tracks:

  Stream Files:
  MAINtimeline-customAVI.m2v (17.85 MB)
  ========================
  since no audio track info appears in the stream info, does this mean my file is multiplexed? What’s the next step?…

  The MPEG2-DVD presets save the audio to a separate file for muxing during authoring (for example, with Encore).

  ok. the files I’m seeing after converting the .avi file into mpeg2-dvd are:

  projectfilename.wav (I can hear it when I play it separately)

  projectfilename.m2v
  (when I play it, there’s no audio track, just the movie )

  projectfilename.xmpses

  projectfilename.xmp

  So I guess I have to combine the .wav file and the .m2v file in another software (such as adobe encore) to get the audio track to play? I was hoping that the conversion from .avi to mpeg2-dvd would include the audio track. Isn’t this supposed to be the case?

  Oh. Now I understand….I guess I was hoping for the same results as converting to mpeg4. that file format retaines the audio track. I thought converting to mpeg2-dvd would do the same. Oh well…at least I learned a valuable lesson.

  You guys at creative cow are amazing! thank you

  What do you want to do next with this file? In other words, why are you compressing to MPEG-2?

  If you want a muxed MPEG-2, use one of AME’s MPEG-2 presets (not MPEG2-DVD).

  Another tip — don’t render to DV for your intermediates. Render lossless (or Quicktime PNG) instead. The file will be bigger, but significantly higher quality.

  Hi, I’m creating a DVD (standard ntsc dv widescreen), this is why I selected the mpeg2-dvd preset from media encoder .
  Isn’t this correct?

  The MPEG2-DVD preset is appropriate, then, but you’ll need to bring both the M2V video file and the WAV audio file (or AC3 audio file, if you use Dolby audio) into an authoring application like Encore to make your DVD.

  Alternately, you could mux the MPEG-2 into a single MPG file with both audio and video within AME in the Multiplexer tab — but you’ll still need to actually author the DVD with something.
