    no sound in ram preview

    odbyt

      Hi, there's no sound in my composition after importing my .mts file into it. The waveform is empty.

      Audio is fine when I convert the file to h264, but I do not want to end up converting my every footage.

      Any ideas what can I do?

          Sorry, but you're stuck transcoding all your footage.  The reason: your audio is embedded in the video track, and AE needs files with separate audio tracks.

           

          Or you could export audio-only, and sync up the track with the video in AE; it could be faster that way.
