Question

How to edit a multiple audio video clip on Premiere

Hello everybody

Maybe this is a dumb question, I'm sorry if I'm asking what is obvious for you, but I swear I tried to find on the web and on this forum, but I couldn't find anything.

Well, I made a video using a screen capture software called Dxtory, that provides me the ability to record my PC screen, with multiple audio tracks.

Ok, now I have a 15gb avi file. When I open this file in the Media Player Classic, I can play one or both channels. The first channel is the original audio captured from my PC. Every audio generated by my PC is in this track. The second track is my voice, with my commentaries. I have all of this in one single file. They are not splited. It's just one file.

Then when I import into Premiere, the software just recognize the video track and the first audio track. I can't find the second, with my voice.

I know I can split the clip into 3 files (1 video and 2 audios) but it would take longer. I just want to drop the file on Premiere and edit the audio volumes quickly, because when I talk I would like to low the volume of the PC audio.

Now, the question: Is there a way to Premiere recognize both tracks in this single file? How?

Thanks in advance for any help.

It's very sad, but the Premier still does not know how to handle such files! Developers simply pretend that these files are not present.

Yes, that's exactly what I do. I use VirtualDub to export that second audio stream as wav and import that into Premiere separately. The tool Colin presented works, but it works slower than VirtualDub.

Here's a much faster and simpler way I found on the Dxtory forums. Right click the AVI file and click Extract Audio Stream. DONE! You can now import the video and both streams in Pr.

An annoying bug in Dxtory 2.0.114 (latest of now): When holding the push-to-talk key whilst holding, for example, "W" (forward walk) and I press any other key, then let go of all keys, Dxtory will keep recording the mic until I press the talk key again. When it continuously records like that, pushing other keys won't stop the recording. I have to repush/tap push-to-talk to stop it, otherwise I hear keys clacking and ambient sounds. I don't see this problem mentioned anywhere on google.

Dxtory does not only come with a demuxer it also comes with a mixer (to mix all audiostreams to 1 audiostream). But either way... it's additional work that has to be done by the user and when processing many files it is a hassle when it shouldn't be any problem at all.

Either Dxtory should be able to mix all audiosources to one track by default - while recording - like all other game recording programs offer; or Premiere Pro should finally import just everything that's in the videofile. The latter would be my prefered solution.

I mean an AVI file with 2 audiostreams (e.g. 2 audio languages) is nothing alien and nothing new... just like a MKV with more than 1 audiostream... which Premiere Pro CS6 ignores completely (MKV that is).

edit: I'm aware that this is an older thread but as I found it via google I assume other would find it too when searching for an easy solution to import an AVI with multiple audiotracks.

I have exactly the same problem as Danilo Salvego, recording a lots of game footage with DXtory gives me AVI files with mutliple audio streams. I am very disappointed, that Premiere, being my favourite video editing software, is not thinking of importing anything more than the first audio track to a video footage in an AVI. This surely is a great flaw and I hope Adobe will make it better in the upcoming verisons of Premiere.

Thanks a lot, Colin, for writing that batchfile for ffmbc which extracts the second audio from the avi.

Can you rip the Audio Streams, and Save as PCM/WAV @ 48KHz 16-bit, for Import as discrete Audio files, into PrPro?

Good luck,

Try using Audacity. Import the AVI file as a RAW file and then export as a WAV file. It will contain loud static, but your voice narration is there. You just have to play with it and eliminate the static and keep your voice. Best to use Audition to edit the saved WAV file rather than PrPro.

Hope this helps.

Is the clip recorded with stereo audio (e.g. left and right channel) or is it dual mono? The Preview Area in the Project Panel should tell you this when select the clip, or you can right-click and select Properties.

Where in Pr are you playing back the clip? In the Source Monitor, or in a sequence? The Source Monitor will only play back one audio channel (that's why I asked if it was dual mono) at a time. However, if the clip is being recognized properly, you should still be able to drop it into a sequence and edit both channels individually, as they will be placed on two mono tracks.

Hi Colin, thanks for your answer.

Well actually I have two stereo tracks. One for the PC and other for my voice.

I tried to modify the clip audio properties, but Premiere allows me to access just the first track.

When I play the clip in a commom media player, both tracks are played.

When I play the clip on Pr, even on the souce monitor or in a sequence, I just get the first track.

There you go: http://salvego.com/download/audio_test.zip

You'll download an avi file.

You'll hear the audio from the game and my voice saying "this is a test" several times, if you play it via Windows Media Player.

Try to import into Pr. I couldn't manage to get both tracks on it. Just the game audio.

I don't know if you'll be able to play it, since it was produced using dxtory codec. You can download the trial version of software software here (it's really small): http://dxtory.com/v2-download-en.html

Thanks again for all yout time and patience.

I'm actually surprised that Pr can import this at all--the video is Xvid. Maybe it's some variant that Pr's importers can handle, as Jeff suggested. I dunno--it doesn't play well for me, regardless, and I'm not going to install the Dxtory codec to find out.

Anyway, to the matter at hand: while AVIs can, apparently, contain multiple audio tracks, Pr's importers are limited to a single track. However, Pr has other importers than can handle multiple audio tracks. QuickTime--which is a wholly different process--supports multiple audio tracks, as does MXF (some flavors). However, Xvid in QuickTime (which is feasible) won't import in Pr (at least on a PC), and Xvid won't go into an MXF file at all; that means you'd have to transcode. Personally, this would be my choice--but I found that the original clip played back pretty terribly, so that would be why I'd go that route.

Additionally, you could extract the second audio track to a separate WAV file, import both the AVI and WAV, and then use the Merge Clips feature to marry them together as one pseudo-clip. Not perfect, but it would work. The benefit is that you don't re-encode anything.

So, I've got solutions for both the re-encode/MXF option (my preference) and the AVI/WAV option. Here's proof of the MXF (transcoded video to XDCAMHD422 50Mbps) with four audio channels (stereo must be split to dual mono):

At the end of the day, these (or a variation of them) are your only options. Pr simply won't import multiple audio tracks (even dual mono) in an AVI container. Let me know if you're interested in either of the solutions.
