Question

AC3/A52 audio codec for Premiere

Good day, everyone. I'm alive again.

I have a video with a A52/AC3 audio on it and apparently the premiere installed in my PC cannot decode it so I have to extract the audio with another software. Ain't there some other way (needless to say, premiere A52/AC3 codec) that I can import my video to my pr pro project in which pr can read its audio data?

I'm using prprocs3.

    I am sorry, but what version are you running? I just have successfully imported ac3 file in my Premiere Pro CS5.5 as well as CS5. Perhaps an issue not with an audio codec but with a wrapper of your file? OR maybe the video portion of it?

    Edit: never mind, didn't notice the Ppro CS3 in your original post.

    Actually you might be on the right track...I am running Cs5 Premiere Pro...from what I understand it should work...it just doesn't!

    It certainly works fine to play in media player/VLC media player/DivXX player....just not in Premiere Pro Cs5...

    so I don't know what I can do...

    thanks for the reply.

    Well I found a solution...a program called Format Factory!

    Very simple with multiple export options!

    Converted to Mpeg4 and Premiere Pro handled that fine.

    Thanks everyone.

      To work with AC3 sound files in Premiere CS3, copy the ad2ac3dec.dll file from the Encore CS3 directory into the Premiere directory

      Thanks John. But I had just done what you've said. Now I am just waiting for Pr to finish indexing and creating peak files for my assets.

      This is a long shot (I am away from my workstation computer) but try importing the file in question into audition and then exporting it as something that PPro understands.

      This may sound lame, Tiger, but I have only heard of the A52 as a highway, regularly filled with serious traffic jams.

      AC3 is imported without problems.

      BTW, I use ProcMon 9.

      Hello, Millaard. Can you still remember re misspelling your name?

      Anyway, about this A52 audio, there's no kidding here. It's there existing. I played my video in VLC, look for its audio stream and it says a52. I googled a52 and I found a page saying a52 is just the same as ac3, both are dolby digital sound. Well, I don't about their particularities but problem is that pr can't recognize the audio of my video.

      Thanks for your quick reply.
