Multiple audio channels?

Hey guys.
Sorry if I get flamed for this question for it being asked before or it being dumb but here goes.
I was round at my friends the other night and he was telling me about some cable he has heard of that can be plugged in to a Macbook Pro that will give you 2 seperate, assignable, stereo channels which would be handy for DJing. Can anybody advise if they have heard of such a thing?
Also, is there a way to isolate the multiple channels on the optical in one cable or would one need some kind of box/reciever to break them out?
I use a multi-channel firewire soundcard anyway so these questions were just really out of interest.
Thanks in advance.

Just drag it underneath the video to connect it, or use the connect edit function.

Export MXF with multiple audio channels for broadcast

Hi,
I work at a broadcast company as an editor. We always used FCP with the free sony xdcam plugin to export. This plugin seems to be one of the rare ways to export an MXF with 4 audio channels. I don't know exactly why we need to export it for broadcasting with 4 audio channels, but we do.
Since our workload has grown enormously the last few months and it will only become more we are optimizing our workflow. We also work with a lot of different endboards in After Effects and we made a nice template to work with. And since AE and Premiere can make a dynamic link we are considering changing from FCP to Premiere.
Now comes the question!: The only obstacle we could not find an answer to is exporting it with 4 audio channels as an MXF from Premiere CS5. Will there be some development on this level regarding CS6?
A solution to this should save us a lot of time!
Any help will be highly appreciated!
I also attached an example for the usual MXF files we export

I have the same problem. I have a project with multiple audio channels and I want to export them as individual channels in a MXF-file.
Method:
When I created a new sequence I choose "Multichannel" from the "Tracks" page. When I export the MXF OP1a, I choose 8 channels from the "Audio" page. None of the channels are muted.
Result:
The rendered file contains 8 channels, but only the first two channels contains any audio (main left + right), the rest of the channels are empty. Channel 1 and 2 contains the audio from all channels, but I want the channels to be seperated in the same way as they are layered in Premiere.
I don't understand your answer to wleoni75's question. Could you please help me further?

Exporting multiple audio channels from Premiere Pro CS6 in MXF OP1a

I have a Premiere Pro project with multiple audio channels and I want to export them as individual channels in a MXF-file.
Method:
When I created a new sequence I choose "Multichannel" from the "Tracks" page. When I export the MXF OP1a, I choose 8 channels from the "Audio" page. I make sure that none of the channels are muted.
Result:
The rendered file contains 8 channels as I want it to, but only the first two channels contains audio (main left + right), the rest of the channels are empty. Channel 1 and 2 contains the audio from all channels, but I want the channels to be seperated in the same way as they are layered in Premiere.
Any ideas what I can do?
Thank you for your help!

Hey Guys,
I'm having problems exporting an 8 channel audio mxf for a broadcast client. The mix they want is as follows:
Track 01: Full Programme Mix L
Track 02: Full Programme Mix R
Track 03: International Sound L
Track 04: International Sound R
Track 05: Music and Effects L
Track 06: Music and Effects R
Track 07: VO Mono
Track 08: Interview Mono
I have setup the sequence following this video on vimeo and am fairly confident I have the sequence settings correct. https://vimeo.com/38501157
I also can export a multichannel mxf. But all my tracks are exported as mono and I am therefore not maintaining my L and R as set up in my sequence
The problem is on exporting that since Tracks 01 and 02 are bounced down to 1 + 2 it means that my Track 01 (Panned L) is getting bounced down onto my Track 02 aswell and thus it does not remain seperate. Has anyone delivered a similar format for a broadcaster and come across this problem with Premiere Pro and know a solution?
Any help would be much appreciated
Thanks

Exporting multiple audio channels Final Cut 6

Does anyone know how to export multiple audio channels out of Final Cut Pro 6 from one quicktime export?

You want a multichannel QT, or AIFF files of the individual channels with one step?

How do I export from FCP to a QuickTime file with multiple audio channels?

I'm delivering a project where the first step is to generate an HD Cam SR master, which I will be doing at a post-production lab. They will then do a QC check for me. To generate this HD Cam SR master, they need to me to bring in my 98-minute long movie on a firewire hard drive, in five equal parts -- QuickTime files. From these five QT files, the lab will then be creating an HD Cam SR master that will have...
dialogue on tracks 1 and 2
effects on tracks 3 and 4
music on tracks 5 and 6
MY QUESTION
a) I don't see any way to separate these audio tracks accordingly in the FCP menu for QuickTime export. Does anyone have any experience doing this?
b) And does anyone know the most efficient way to combine timeline audio tracks for this purpose? I have my dialogue sitting on the first FOUR audio tracks, actually. To deliver this film, I'll need to crush these four audio tracks to two, as listed above. I could generate an AIFF file, I suppose, import it back onto the timeline, sync it up, and then re-export along with the visuals to make the final QT file, but this seems like a generation loss.
thanks,
Shanked
PS the movie is made up of footage from a Sony PMW EX1. I used the codec "XDCAM 1080 24p 35mbs VBR" for editing in FCP. I'll either export to QT using this same codec or switch to "Apple ProRes" if my machine can somehow maintain the sync.

The following will answer both your questions a) and b).
Click on your master timeline and press cmd+0 (zero) to bring up Sequence Settings, then click on the Audio Outputs tab on the right. Click on the Outputs option and change it to 6. You can leave them as Stereo pairs.
Now, back on your timeline, you need to make sure all your audio is organised so each track. A1, A2, A3, A4 etc has all the relevant media on it.
Then, on the left of the timeline you see the Destination toggle buttons, then you see the Padlocks to lock tracks, then you have the Toggle Auto Select squares. If you right-click on the Toggle Auto Select squares you bring up a little sub-menu, at the top of this list you'll see Audio Outputs, which will show the stereo channels for that particular track. As you've changed the number of Audio Outputs in the Sequence Settings, the list will show: 1&2, 3&4, 5&6. You just tick whichever channels you want.
In your case, you have dialogue on the first 4 tracks, no problem, just go down through tracks 1,2,3 and 4 as described above and assign these to Audio Outputs 1&2.
Then just go down through your music and effects audio tracks and assign them accordingly.
Now, when you export your timeline as a self-contained media file, it will have different audio channels.
I hope that makes sense. When you change the number of audio outputs as described in the first step, I believe the rest of it is fairly self explanatory, once you know where the settings are.

Help using multiple audio channels for one video

Hi,
I have a video file with 3 audio files (stereo (.wav), 5.1 surround (.AC3), and commentary (.wav).
I have placed these on the time line of the video track, but now I need to have buttons to target each of them from a menu. However, when is choose a buttons target, is doesn't give me the option of which audio channel to play (A1/A2/A3 etc).
Is this possible with just one track, or do I need 3 (each with a different audio file as A1)?
Hope you can help! cheers.
Tim

There is a tutorial on setting this up here;
http://www.kenstone.net/fcphomepage/dvd_languagenattress.html
BTW I would very strongly suggest to compress your WAV files to stereo AC3 files. It will reduce your overall bandwidth, and you will have a disc that will less problems in playing.

Exporting QT file from FCP with multiple audio channels...?

Is there a way to export a QT file out of FCP that will not mix down all of your audio? This file could be a FCP QT or just a regular QT, doesn't really matter!
But If I wanted to edit with self contained Qts that had been synced from a wav file that had 8 tracks, Each from a different mic. How is this possible?
Thanks in advance.
Jesse Korosi

Hi -
For FCP 7:
Click on your timeline.
Type Command - 0 (Zero) and click on the Audio Outputs Tab.
Change the number of outputs you want, and set the track pairs up as stereo or dual mono, as you want.
Click OK, a warning dialog box will come up that you can dismiss.
On the timeline, Option-Click on each audio track right below the auto-select toggle icon, and from the drop down menu, route the track to the desired output track.
When done, export the Quicktime movie.
The only way you will verify that all the tracks are there is to either open the exported quicktime in Quicktime pro and menu Window > Show Movie Properties. You'll see the additional tracks listed there -OR- just import the exported movie back into FCP and bring it up in the Viewer, you'll see all the audio tracks.
Make sure you restore your sequence back to two channel ouput, if you want, when you are done.
Hope this helps.

Export multiple audio channel in same video file in premier pro

OK I have tried a lot and searched the net a lot a lot a lot, but unfortunately I didnt reach anywhere.
What I am trying to do here basically is that I have all my footage setup in premiere. In my Audio section I have included 4audio tracks (each for a specific language). How do I export this video so that 4 tracks are available, you know like tetra audio for a dvd.
I'm asked to do this in avi format, does the format matter or it has nothing to do with it.
Please save me!!!!!!!!!!!!!!

4 different exports, one for each language.
AVI is a container, not a specific format.

Any way to export QuickTime w/ multiple audio tracks?

I remember seeing QuickTime movies where on playback you can select which audio tracks to listen to. Kind of like director's commentary or different language versions for the same video stream...
Is there a how-to guide for making a movie like this in FCP? We have one video file and multiple audio files that we've placed in different tracks in the timeline but when we export to a QuickTime movie they get all merged together. We tried setting it up with multiple audio channels and then control-clicking to get that menu with each audio track and putting them into the different channels, but there must be something we're missing...
Is this something only FCP 6 can do? I think we have version 5.
thanks!

I'm a little rusty on this - and without access to FCP 5 at the immediate moment - but I think the key is to set your sequence to have multiple (as in more than 2) audio outputs, then select Channel-Grouped for audio during the Export via QT Conversion.
If that doesn't work, you could always paste additional audio tracks onto your movie in QT Pro. After all, you'll need to tweak your language settings for audio track in QT Pro.
But where have you seen this implemented to do a Director's commentary-type option? I've read that multiple (discrete) audio tracks work only if they're tagged as different languages and the user's playback system is setup for one of those languages. (But I've been wrong before...)
And welcome to the forums.

Capturing 4 Audio Channels - HDV???

Correct me if I'm wrong, but it is NOT possible to capture 4 audio channels all at once in FCP?
If this is this case, how do you go back and capture in another pass? Right now I can only capture the two channels that go along with the onboard mic, and not the channels that go with the XLR audio (in this case a Lav Mic.)
I've tried to create a new capture preset, but it doesn't seem to work w/HDV.
Should I try capturing the audio in a second pass using standard def? Would that work?
Any thoughts would greattttttttttttly be appreciated.
Thanks!

As Thomas suggested in that thread, "Capturing Multiple Audio Channels", in chapter 20 of the the FCP User Manual is a great resource. But I'll break it down for you anyways...
Here's how I capture 4-tracks of audio via Firewire with Final Cut Pro:
Go to -
Final Cut Pro Menu/Audio/Video Settings.../Capture Presets Tab
Create two capture presets (1 set for the first two channels, the 2nd set for the last two channels and maybe one for all 4 channels mixed if you'd like)
Select a Capture Preset and choose Edit then set which channels you'd like the preset to capture inside the Quicktime Audio Settings section of the Capture Preset Editor window. Make sure your device is plugged in and turned on or else the option will be greyed-out.
Open the Log and Capture window in the Capture Settings tab and select which Capture Preset you'd like to use depending of which audio channels you'd like to capture.
To make sure you're caturing 4-channels on your camera:
Go To-
Menu/Audio Setup/Audio Mode/ 12bit 1/2 , 3/4
Throw the phones on and monitor the channels using the Audio Monitor button on the side of the camera. You can switch between monitoring the first 2, the second two, or all four channels at once. Remember if the camera is set to record 4 channels then it'll record 4 channels no matter what channels you're monitoring.

QT AVI only supports 2 audio channels?

Just want to run this by the forum and see if anyone agrees.
QuickTime AVI export seems to only support mono and stereo audio? Is this absolutely true or is it possible to export AVI with multiple audio channels?

Yep, that's just how it is.

Enabling AirPlay to multiple speakers causes audio channels on local computer to playback incorrectly

iTunes has an audio bug that has been a problem for the last couple releases and it's been driving me crazy lately. The problem is streaming audio to any AirPlay devices from iTunes causes iTunes to for lack of a technical term "munge" the audio placing back out of the local audio output. It seems like stereo audio stops playing out of the local audio output and instead either the left or right audio channel plays back out of both speakers. The stereo channel audio playing out of the AirPlay device appears to be unaffected.
This can be reproduced by:
1. launch iTunes when AirPlay output device is available (AirPort Express, AppleTV)
2. open the Multiple Speakers panel
3. make sure both "Computer" and one other AirPlay output device are checked
4. playback an audio track you are familiar with that has clear stereo separated audio (something with a vocal track with one singer mostly on the left channel and another mostly on the right channel is a good option)
5. the playback will sound odd, like parts of the recording aren't present - vocals quiet or missing; guitar riff quiet or missing
6. uncheck all AirPlay output devices so that only "Computer" is selected
7. listen to the audio track again, it will sound normal
-- if you identify where the audio has missing elements you can click the AirPlay output device on and off in the Multiple Speakers panel and hear the elements magically appear / disappear
A great track to test with the The Beatles / Revolver / Taxman. From 1:12 - 1:25 there is a guitar solo. With the AirPlay device on this solo is completely missing and the track just has bass, drums, and rhythm guitar.
I'm not certain this has to do with stereo audio channel issues on the local playback, but obviously as soon as the AirPlay streaming code kicks it, something with the audio channels on iTunes is getting hosed. It's only been an issue for the last 6-9 months for me and audio streaming worked great for years before that.
Can others reproduce this problem? If so, Apple really needs to escalate this for a fix because using AirPlay pretty much ruins the quality of audio output currently which makes me never want to use it.

don't know if you are still looking at this thread, i hope so.
I have a similar problem, and I wondered if you might help. I have a macbook (2008) running the latest version of itunes (just updated) and Airplay tho with a pretty old router. (I got a relatively new one for the network just a few months ago but the one hooked up to my amplifier is an old airport-- the square ones-- I have had for years -- it's linked to the amp via the 3.5mm output jack)
I seem to run into this on the "Rubber Soul" album, and I checked it agsint the copies from iTunes and even ripping another edition of the CD. The vocal tracks seem to disappear, like the guys are singing at the bottom of a well. "Run For Your Life" for example, the verses Lennon sings are almost inaudible. On Norwegian Wood it sounds like they are in an echo chamber a mile away.
So, on all my other music it seems fine, but I wasn't sure if Steve Jobs hated "Rubber Soul" or what.
I haven't duplicated this on other music -- tho just now I noticed some weird effects on the opening track of Sgt. Pepper. Only half the vocals are on, the lyrics by Lennon are again near-absent) I might try to see what happens when I play the mono version of my Jefferson Airplane CD.
Is there a software fix? Should I be linking my airport in some other fashion to the amp? (The amp is pretty old, I got it in what, 1998?) Should I be using the USB link somehow to the audio out? Is thi an effect of weird stereo mixes of the 1960s?
BTW I am not trying to tream to multiple devices or anythign, just to the one.

How to link video and audio channels of multiple clips

Importing iMovie08 sequence via XML ends up with unlinked video and audio channel (only one of the stereo channels; see other post).
It is possible to link each clips audio and video track individualy.
Is there a way to do it in batch mode for all the clips in de timeline??

Dennis Connors wrote:
1. After selecting the in points on main audio and one of two video tracks, the "merge clips" is greyed. Yes,in case you're wondering, the audio is on the HD.
Your use of language is confusing me I'm afraid. You opened the AIFF file and set an IN then opened a QuickTime movie and set and IN and then with them both selected in the Browser (and the Browser the active window) that you cannot select Modify->Merge Clips... ?
I wasn't wondering anything about your audio, but now I'm wondering "What does 'the audio is on the HD' mean?"
2. The other issue is that the starting point is silent, so the only I know how to find the actual beginning is by counting frames back from the first sound. Is that what I have to do? Is would seem to me that there must be a "marker" that's not and "in" or "out" that will allow me to merge the tracks. No?
If you set an IN point in two clips you can merge them using the Merge Clips... command with the in points option. The IN points you choose can be anywhere and for anything. They can be where the clapper hits and sounds, they can be where a drum stick hits a cymbal, they can be where someone is clapping, they can be where a body falls from a building onto the sidewalk... Anything that helps you sync the sound with picture.

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.

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.

How do I import multiple audio tracks?

Hi there...
I have a number of video files that have multiple audio tracks in them. The problem is I can not work out how to get prem to see multiple audio tracks. The files import fine and I have also tried various other formates with multi-track audio.. but only audio "stream 1" is visible in prem.
What I was hoping is that the video would come in with a 2 audio tracks instead of 1 each in its own "lane".. so I can then use the mixer and the audio files are linked to the video file and in perfect sync.. (just like when you import with 1 track)
NOTE: I am not talking about channels.. but complete 2 completely different audio tracks.. and I know that I could extract these audio streams into wavs and then re-sync them but this seams overkill and a duplication of effort... surly there is a way to have prem support more than 1 audio track on a video file?
--Me

Well, if PP doesn't bring them in, then best guess is they just don't exist.
There's really no trick or user adjustment for this that I'm aware of. You import the file, PP sees what's in it. I've never observed or read about any other behavior than that.
