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.

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.

But I just found something here:http://www.mediacollege.com/adobe/premiere/pro/import/mpeg-ac3.html. I hope this would solve my problem.

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.

Thanks for the quick reply...much appreciated.

I don't have Audition with the laptop I'm on (don't think they included that with Cs5 bundle)...

but I'm trying Media Encoder instead as I write.....so thanks for the tip.

(I need to get this done within the next hour or so! Have already been working on it for about 2 hours)

I also tried Virtual Dub...I used the standard "Save AVI" feature...it produced another AVI file..that again plays fine in various media players...but when I import it into Premiere Pro...only the video comes in...and no audio track at all...

Various posts refer to using Virtual Dub to convert to DV AVI...but unfortunately I cannot find any explanation of how exactly to do this...there is no "Save or export to  DV AVI" option I can find in Virtual Dub....(I've tried downloading a VFW Panasonic Codec...which apparently is of some help with this)

Other option might be After Effects I guess...or maybe a free video editor off the net?

Open to anything at this point!

Thanks!

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.
