Importing mpg files – audio disappears

[Vincent Rosati]

Sure sounds like a codec issue. If you use video from different sources I’d recommend GSpot for codec identification…

Aside from installing a codec that Premiere can use, I usually decompress odd source material before import. I use AVS Video Converter…
https://www.avsmedia.com/VideoTools/

It usually does the trick.

Thanks Vincent, I’ll check those apps out.

Well, it said that the codec’s were installed. I left for work with it converting the file so I’ll try the converted file tonight..

Ok, I don’t know why (which bugs me) but AVSVideoTools converted it successfully so that I could import into Premiere and have both, video and audio..

So now I have to register it and redo to get rid of the watermark.

But if anyone knows what’s happening (I know – long shot) I’d love to hear an explaination.. (even if I don’t wind up understanding it! lol)

Thanks again Vincent!

Going back to your original question, if you open both of your original files with GSpot you could let us know both the audio and video codecs that are being used in those files.
Remember, Premiere is an editing app and it works best with editing codecs. For instance, you can edit MPEG in Premiere but it doesn’t work that well.
I’m not sure of the list of Premiere’s acceptable codecs as I always edit in DV or Uncompressed. That info is probably in the documentation, and likely to be on the Adobe site somewhere.

Yeah, I normally only edit uncompressed avi’s but have typically (though I’m sure it’s not the best way to do things) open the file in Premiere first, then export it out without doing much of anything – maybe trim the head or tail but that’s it. Then I import the exported, uncompressed avi into my project and go to town..

I’ll post the codec’s that are in use.. Perhaps I’ll register the software you mentioned – though I found that I have a registered version of TmpEnc which seemed to work out for me – well, the ripped DVD I was able to trim down to the scene I’m interested in while converting it to various different formats (tried several with same results) and while I’m able to import into Premiere and get video and audio, Premiere crashes on me if I try to render or export (haven’t tried to do anything else yet..)

Anyway, like you said, it’s prob a codec problem so I’ll take a look at that tonight, and post it when I get home..

Thanks again for your time Vincent,

Hello,

I am having the same issue. I am importing mpeg-2 files from a JVC Harddrive based camcorder. When I would import the files and add them to the time line in Adobe Premiere 7.0 it added the audio track without any issues. Now that I switched to Premiere CS3 when I import the files it adds no audio track, and I can’t find a way for it to automatically extract it. Does anybody have any ideas on what would have changed between 7.0 and CS3? I am assuming it is not a codec issue as 7.0 had no issues on this same PC. I also tested adding an mp3 file to the timeline and it had no issues playing the audio from it. Also, even when I play the file in the source window, it does not play the audio. Any help would be greatly appreciated.

Thanks for your time!

Patrick,
If I find the answer to our problem I’ll certainly let you know! (please do the same if you find out what’s going on)

It’s going to be quite frustrating (and time-consuming) to have to convert the footage first.. Though it may just redefine my workflow a little and I’ll do my ‘capturing’ and initial footage cut in a different app..

Copied from a forum, can’t remember which one:

If your MPEG file contains AC3 (Dolby Digital) audio then Mitch411 said:

If you’ve got Encore CS3 installed , copy the file ad2ac3dec.dll from
the Encore CS3 directory and paste it into the PPro CS3 root directory
. Once you restart CS3, you’ll be able to import the file with the
audio. This means if you’ve already have a project with the files
imported, you’ll need to remove the files from the project and
then re-import them, or just start over with a new project.

Eddie, you’re right. PPro doesn’t import files with an AC3
extension, but it did import ac3 audio embedded in mpeg files
from DVD camcorders. The ad2mcac3dec.dll that was included in
2.0 allowed those ac3 files to import as stereo (but not 5.1).
It looks like that functionality was removed or broken in
Premiere Pro CS3, but the functionality still exists in Encore CS3.
You can copy the file over from Enc to PPro and get the
functionality back. You may end up breaking something else, but
it does work to allow the AC3 audio stream in the mpeg file to import.

Hi,
I have the same problem with mpeg files and PPCS3. Now I have a new camcorder Sony HDR-SR12E that makes AVCHD format files. PP can’t operate with avchd format at all (hopefully soon), so I convert the files to mpeg format for wider editing. The video and audio is rather good when looking e.g. WindowsMedia, but importing PP there is no audio at all! The converting program that came with the camcorder is Picture Motion Browser (PMB). There is no possibility to change codecs. In WM the audio codec in mpeg file is named Cyperlink Audio Decorder (PDVD7). So, what to do? Has somebody an idea?
