    Sound disappearing...


      Just started having a really strange problem... I brought in a bunch of P2 clips newly imported from my HVX200 camera. When I click on them in the project window they all have sound. Yet, when I bring them into a composition (even just drop them onto the composition icon just to create a whole composition around the clip with no effects at all) all the sound disappears and is replaced by just some low decibel noise. No recorded signal at all.

      What could I be doing wrong here??? Must be some kind of setting I accidently hit with a keystroke?

          Check your audio prefs. Sounds like a mismatch in your settings somewhere. Other than that, it may hinge on which channels the audio is in the MXF files. Do they behave correctly in Premiere?

            Thanks Mylenium, and good morning to you!

            I don't have Premiere, but the files playback perfectly in Quicktime.

            I checked my Audio Output Mapping and it's set correctly - Map Output for MOTU UltraLite
            Audio Hardware is set for MOTU UltraLite Buffer Size: 512

            What other settings could be incorrectly set? Again, I am able to play back the files within AE if I double click the files in the project folder.

              A quick fix would be to use QuickTime Player Pro ($29) to export the audio as uncompressed WAV files and import separately. Not as elegant, but you'll get the work done.

                Thanks, Jonas. Yes, I did end up doing that. Wish I could figure out what happened though! It's true, the camera does output 4 tracks of sound and two were blank... but odd that quickimte shows the ones with sound, and the track when imported in AE says mono...

                  Well, AE still is strictly a stereo app. Incorrect channel mapping and interleave might throw it off track, naturally. I guess you could prevent some of the problems by changing your camera's configuration to bring it more in line with what AE might expect.
