Audio Channels in Timeline

Can I break out audio channels, or eliminate a R channel once I've dropped it into the timeline? I have separate mics on L and R channels, and want to just choose the L channel mic. But I failed to set channels on all clips before moving into the timeline.

You'll get different suggestions/methods, but what I use is the FILL LEFT and FILL RIGHT audio effects. If you want just the mic on the left channel of a stereo clip, add FILL LEFT and then you will only get the left channel audio, on BOTH the L and R channels.
To expand on that, you could copy/paste to duplicate the clip, and add LEFT to one clip and RIGHT to the other, and then mix them as if they were seperate channels to start with. Or, add razor cuts to single audio clip at points where you want to switch mics L or R, then alternately apply the effect as needed to each segment and add audio crossfade at cuts. Many ways to work with it.

How to show different recorded audio channels in timeline

I've recorded an interview with two microphones (one was really bad, so I only want to use the other recorded microphone). I imported the clip from the tape camera into FCP X. Now in FCP X on the timeline I only see one audio track when I seperate it from the video. The two microphones seems to be 'mixed'. This was different in FCP 7 where you see both audio channels seperated.
How do I manage to seperate the 2 audio channels into 2 channels. I'v troed with Channel Configuration via Audio Inspector but I do not understand it.
Thanks, Pim

Select the clip in the timeline and in the audio tab in the inspector in the channels seection switch to dual mono. You can switch off a track here if you wish.

Audio Channels in Timeline Keep Changing?

I have some audio tracks, on those tracks I inserted a .wav file that has 4 channels. I only need 2 channels. ( 1 and 2 ) I unlinked the audio and I am just using channels 1 and 2.
Channel 2 on the timeline keeps defaulting to Channel 1 - I change it and then next time I open the p[roject the audio on channel 2 goes back to channel 1.
I hope this makes sense.
This picture is what it needs to be
This picture below is what it changes to and I have to reset the channel.
Below is info on the audio channel
Im doing something wrong right?
I hope not because I have already layed in and adjusted all my audio.
Thanks for your help!

Thanks for your help. I haven't made a copy of the WAV.
In the timeline, the 4 channels are linked together. Ch1 is a LAV Mic, Ch. 2 is a Seperate LAV mic, Ch. 4 is a boom mic and there is nothing on channel 3.
So I unlinked the WAV file in the timeline and removed the audio channels that I did not need in the timeline.
Then I moved the 2 LAV mics to Audio Channels 1 and 2 on the timeline.
I think that is when I noticed that both Channels were the same... not sure - I have moved stuff around so many times.
So in the timeline, I would "right mouse click" on the audio track in the timeline and modify the audio clip by clicking on audio channels.
As a work around, I modified the LAV audio clips in the timeline to where they needed to be and did an audio mixdown of just my LAV mics. Brought that file back into the timeline and muted the others that kept changing on me.
Does that help? Thanks again!

Determining which audio channel a timeline clip came from

Hello,
How can you tell whether the source of an audio clip in the timeline came from channel 1 or channel 2 on the master? I've tried Clip Properties but that only shows which timeline track it's in (which is fairly obvious if you've just selected it).
Many thanks!!
-- Sean

Sean, its a very good question that sadly has an hopelessly inadequate answer.
Of course FCP does know exactly which specific channel of audio (from a multi-channel source) that it's referencing, but there's just no easy way of determining which channel that is after the edit has been made. In some situations I can see exactly how and why that would certainly be very useful, just as it would be useful (especially in fast turn around editing) to be able to simply reassign an edit instance's audio source channel after the fact eg to be able to target an audio clip instance and simply switch it's content from say ch1 to ch2 of the source.
As it stands, although it's possible to do this in other NLE's its not yet possible in FCP. As always, you can send feedback to Apple's FCP development team at: http://www.apple.com/feedback/finalcutpro.html
Ok, heres what you can do If its absolutely essential that you correctly identify your edit's audio clip's channel sources: you need to export your sequences as XML files (File > Export > XML). The exported XML will contains the full make up of your edit, including every clip instances audio channel sources. Its not especially human readable but neither is it encrypted, its just a plain text file .... so you can open it up in Text Edit and figure it out.

Flipping audio channels on timeline

i recorded a number of audio tracks that i need to flip.
i recorded my good shotgun mike on channel 1 and the camera mike on channel 2. channel 2 has noise i want to eliminate.
when i imported to fcp, i imported as stero pairs and i would prefer not to have to re-import all those clips as separate channels.
i would like to eliminate channel 2 and pan channel 1 to both channels.
so in essence, with one clip, in the viewer window i want channel 1 on top and channel 2 on bottom. then if i dupicate the clip and put it underneath the first clip in the timeline, in the viewer window, i want channel 2 on top and channel 1 on bottom.
i somehow managed to accomplish this yesterday when i was folling around and trying things, but i don't remember how i did it and now i can't repeat it.
so how do i do this please?
thanks
carl

Select the clip in the Timeline and unlink it from the video clip. Next, if the two audio tracks are a stereo pair, change that by going to Modify->Stereo Pair. Once each audio clip can be selected separately, delete the channel 2 clip. Double click the channel one clip and change the pan setting to 0.
Or, load the clip from the Browser into the Viewer. Set the Timeline target tracks for only the channel you want (plus video if you want that also).

Only one audio channel in timeline?

I’m working in FCP 6.06 and I don’t how or why it’s happened but I only have one audio track in the timeline. The audio is set to dual track mono. I’ve tried copying and pasting the track from channel A1 to A2 but it doesn’t work. I assume there is some important reason mono would be displayed in two tracks. Is there some way for me to fix this?

Yes, it’s centered already. Very strange. Don’t know what I did when I brought two-channel mono from one sequence to another that caused it to become a single mono instead of dual mono. If the quality does not suffer then I guess it makes no practical difference as long as the sound is coming equally from both speakers.
Thank you both for helping me out.

Feature Request: Modify Audio Channels from the Timeline in Premiere CC.1

Why have we never been able to modify audio channels once a clip is added to a sequence? I'm guessing there's a good reason Adobe has never had this feature. The lack of this feature is explicitly mentioned a few times in the audio section of the Premiere Pro CC manual, as if it's a benefit NOT to have it. But the benefit is entirely lost on me.
In my workflow, I synchronize my double-system video and audio before anything else. I do this in PluralEyes (and unfortunately I'll have to keep doing it this way, until PPr's sync on sound feature gets fixed—for me it's never worked).
Once PluralEyes has synched hours of footage and audio and placed it on a PLURALEYES GENERATED sequence, I import that sequence into Premiere. Note: Since I haven't gone through the step of creating a blank New Sequence, I don't get the opportunity to setup my audio channels the way I'd like in my sequence (i.e. Stereo recordings should occupy ONE track, not two. Typically these tracks come from a camcorder and are used for reference sound, or ambient noise at best, so I don't need them taking up precious real estate in my sequence).
Since PluralEyes doesn't merge my clips for me (or rather I don't want it to since I'm usually doing multi-cam sequences where I want to keep all 14, or so, tracks of audio), I have to go through the clips one by one and do a Merge Clip action once I've adjusted any minor sync issues, or determined which tracks I actually want to keep. But, and here's the key, at this stage I'm not yet 100% certain whether I'll use the nat sound or the wireless mic sound (separate audio recorder, etc). Furthermore, I don't really want to think about that at this point. After I've spent a few mind-numbing hours just ingesting files, sync and merges, I want to jump into the edit as soon as possible, before I lose all will to finish this edit. If I modify my audio channels right now, I'll lose the ability to make some creative decisions later on.
I'd like to start whacking out an assembly edit. And then after I have a rough program, I can start looking at which audio tracks (nat or double-system) I like better in each circumstance. This is where I become stumped that at this stage, I'm locked into whatever audio channels I've setup (or not) in the earliest stage of the edit, back before any media was actually on the timeline! It's at this stage, and usually only at this stage that I want to start Modifying Channels—FROM THE TIMELINE!
Does anyone else feel the same? If not, what is your workflow?
Feature Summary: Right-click on any clip, (master clip, sub-clip, merged, nested or otherwise) in the timeline and choose Modify > Audio Channels.
I've submitted a feature request, with a link back to this discussion, so please pipe in—especially if you want this feature.

Maybe its your specific workflow, asset mangement and use of a 3rd party application that runs you into an issue.
Take Pluraleyes out of the equation, I would imagine my workflow is the same as most everyone else. Find footage in the Media Browser. Import it. Create a Sequence and start editing. Use the Source Monitor to set Ins and Outs and then Insert the clip on the timeline.
At this point, if the audio needs to be modified, it cannot be done on the Timeline. The workaround, of course, is to Find Clip in Project; Modify Audio in the Project panel; then do a Matchframe to replace the audio clip. This works, but requires many steps per clip. Also, Matchframe in Premiere Pro CC is not reliable.
Introducing a new Modify Audio (from Timeline) feature as seen in the fantasy screenshot above would solve it.
I dont use Pluraleyse ...which I understand to be a synching aid...so I dont know the workflow it imposes on one .
Returning to Pluraleyes workflow, this issue is compounded by the need to Modify almost ALL audio. Every stereo track is separated and placed on two MONO tracks taking up precious real estate. This is not something Pluraleyes imposes. It is due to the way Premiere imports XML timelines. This would apply to sequences imported from Final Cut as well.
In this case it would be ideal to select both the LEFT and RIGHT mono tracks and choose "Modify > Audio Channels > Merge L/R Mono to a Single Stereo track." Ideal? No. I guess Ideal would be if Premiere would interpret XML files properly in the first place.
What actually is the issue with Premieres synch and merge workflow in your case?
Audio Sync in Premiere Pro doesn't work. Period.

Premiere Pro Timeline with 3 video channels and 4 audio channels, audio channels change to 8 channels when clip dragged onto timeline.

Premiere Pro Timeline with 3 video channels and 4 audio channels, when clip dragged onto timeline audio channels change to 8 channels. Audio track mixer changes too. I edit undo to remove dragged clip and it reverts back to 4 channels of audio on timeline as does the audio mixer? Any ideas as to why the audio channels and mixer changes?

you can check the clip you are dragging to the timeline, if it has 8 tracks... can check by right clicking it in the project bin, choose modify, audio channels.

Hearing only one audio channel in source window & in timeline

Hi all,
As most of you I get a lot of footage where the audio is split - left channel for gun-mic\\front-mic and right channel for neck mic.
A lot of times I want to preview only one audio channel in the source window.
I cant find a way to do it.
Also whan I try to hear\monitor only one channel when the clip is in the timeline - its a problem -
the only way I know is by using the fill Left\Fill right effect - it is good when I do the final mix
but sometimes I just want to hear one of the channels.
without the tidius way of adding an effect just to preview something and then deleting it.
I'm sure there a way to do this - right?
thanks!

Thank you very much for replying
Select the clip in the Project Window and duplicate.
Select duplicated clip > clip > Audio Options > Source Channel Mapping.
Disable one of the channel and hit OK
Place this clip on the timeline and ALT + double click so it will open in the Source Monitor.
This is a very messy and unconfterble way to work - because I need to toggle this every time I want to switch channels to monitor.
Instead of adding the effect fill left/right you can toggle the effect on and off for the whole track in the Audio mixer.
This is a nice solution when I work on the timeline - but it won't help when I go on the source footage.
I think the only way to switch channels for a quick preview in premiere is by buying a Sound card with a channel switcher - or using a mixer...
so dissapointing...

The right audio channel is no longer heard after effect assignment in the timeline

Sorry, but my English is not so good, but I try to explain the problem:
Once I clip any one assigns an effect in the timeline, works when playing only the left audio channel channel. Once I pull the clip from the timeline into the project window again, then works again the left and the right channel. How do I get the right audio channel in the interface window active again?

When I look at the properties of the file in QuickTime, here's what it shows:
DV/DVCPRO - NTSC, 720 x 480 (640 x 480)
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Left
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Linear PCM, 16 bit little-endian signed integer, 32000 Hz, Unused
Why it's telling me the other 3 channels are unused, I have no idea. They certainly are getting used. The footage was shot in stereo and Final Cut plays it in stereo.
Here's what VLC says about the very same file:

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.

How do I select just one audio channel in Final Cut Pro X?

I know this has been asked and answered somewehre... and I'm pretty sure the answer is simple. But I don't have hour's to search the net.
And the FCPX "Help" feature just ****** me off....
I recorded voice on channel 2 and shotgun nat.sound on channel 1.
I only want the voice track (channel 2) to playback in stereo.
I have already edited the video so I don't want to re-import the raw video to seperate out just the channel 2 voice track.
How do I select just one audio channel in the timeline, then pan it so it plays back in both the L and R channel?
Also, some of the audio was recorded with a air conditioner running in the background. Any suggestions on best audio filers to remove or lessen it?
Thanks, Barry

I think you want to select the clip in the Timeline, choose the Inspector and then Audio, dual mono.
You can even do this by selecting multiple clips.
In the Event Browser as well.

Stereo Audio channel turns to mono when I close and re-open the project

Hi there,
when I import a random video file with stereo audio channels and put it to the timeline (after peaking), everything works allright - the recording level window shows me the left and the right audio channel.
But when I save and close the project in order to re-open it directly, I only got a mono audio channel (left) and the stereo is away in my timeline and recording level window. The preview of the imported video ist still ok with stereo sound.
Is this a bug ? What can do? Please help me.
Thanks a lot

Uneven audio channels

The audio in the timeline is uneven. If I isolate the channel are there any adjustments I can make to improve the sound? I know sound is the worst thing to be trying to fix. But any advice would be great. Thanks.

Or use the Compressor / Limiter filter ( Effects > Audio Filters > Final Cut Pro )
http://www.geniusdv.com/weblog/archives/compressor_limiter_with_final_cut_pro_to _fix_audio.php
The AUMultibandCompressor filter ( Effects > Audio Filters > Apple ) gives you the same controls but more so (allows you to apply the differing amounts of compression to differing frequency ranges).

How to separate audio channels?

Hi guys, I'm a new Premiere user coming from Avid and I have some confusion working with audio right now.
I filmed some interviews with a radio mic on channel one and channel two was recording from the onboard mic. In Premiere I want to bin the second channel and pan the first channel across left and right. The problem is I haven't got a clue how to do so! This was a doddle in Avid and I'm sure it's easy in Premiere.
Could someone give me a hand here?
cheers
Rich

"Took me all of 30 seconds to find the answer to your original question there. It even has it's own heading"
I did search. I promise! Just out of interest what did you search for? I clearly couldn't see the wood for the trees
Edit; Just so you know I wasn't being a complete muppet, I did watch the Adobe video "Mapping audio channels in Premiere Pro" which gave the impression there was no way of fixing the audio once it was on the timeline. It didn't mention the fill left/right effect.
