Exporting as Dual Mono

I must be missing something... I record voiceover audio on track 1 (left channel only - using Tascam US-122). Sounds great within Soundtrack Pro. But lately, when I export this as a dual mono file, the left channel sounds completely hot. How can I export dual mono without having the levels so out of whack?

While you like to think of the two files, once linked in FCP as a stereo pair, you captured dual mono and that is what the material is. FCP is a non-destructive editior. It will not change the original files - and that is what STP reads.
The other way around this is to take the file offline in FCP then recapture it using the correct audio setting (stereo).
Good luck,

How to export a dual mono file to play in quick time?

My source video file is stereo with left and right channels having different languages.
In FCPX I set the audio to "dual mono" but cannot export in a way so that I can select the audio channel/ language in Quick time.
Thanks for any advise.

Hi George,
Thanks! It does work in XML format. But since I would need to present the data in a spreadsheet, is there any other way I could go around it?
Cheers,

Why Does FCE capture DV audio as dual mono instead of stereo?

FCE captures DV audio as dual mono audio files instead of a single stereo audio file. You can see this if you "Show Movie Properties" in Quicktime. Files I captured in Premiere 6 years ago have a single stereo file. The problem is that the new dual mono format for DV won't play on the Final Cut Pro 3.04 installed on my wife's G4 (OS 10.4.11, Quicktime 7.6.2). FCP 3.04 doesn't see any audio for these dual mono files though it will play the video. It won't even create an audio waveform. But FCP 3.04 plays the older stereo audio clips captured in Premiere just fine. And if I export the dual mono files out of QT as a stereo file, then FCP 3.04 will play them just fine.
This lack of backward compatibility is quite frustrating. I can't seem to find a setting in FCE that will capture audio as a single stereo file. Why isn't NTSC DV always stereo? I guess maybe they had to go dual mono to facilitate surround sound panning in 5:1 or something. If nobody knows how to do this in FCE, I guess I'll just capture in FCP 3.04. I spent the better part of a day figuring out this hidden little tidbit. The lesson is don't try to go back!! We must always accelerate forward into newer versions and formats.

The problem is in your wife's machine. She is using a version of the OS and QuickTime that are much too new for the version of the software she's using. She really not not be using an OS newer than 10.4.10 and QT should 7.2 or earlier.
Yes. I was beginning to suspect that this was at the root cause of my issue. Thanks for the info. Frankly, my wife needs to buy a new Intel iMac so we'll both be able to work on the video I'm dumping. I had FCP 3 lying around from years ago and it's the only thing that might have worked on her old G4 AGP, so I thought I'd give it a try.

Exporting dual mono

I must be missing something... I record voiceover audio on track 1 (left channel only - using Tascam US-122). Sounds great within Soundtrack Pro. But lately, when I export this as a dual mono file, the left channel sounds completely hot. How can I export dual mono without having the levels so out of whack?

I figured it out; the audio default for new projects in FCPX is surround. Without even going to the project, but just being in the Project Library, you can select one of the porjects and in the information window it shows the project properties, and the ones my issue existed in were each in Surround. I simply hit the "wrench" in the corner and changed Surround to Stereo. My only question though, is why would a mono track panned center (and plays back center during editing) end up hard right in export? Also, why does the same Surround project in Compressor correctly end up with mono tracks centered even if the Surround project remains in Surround?

Stereo audio export showing as mono

Hi,
I've been encountering an issue with exporting stereo audio from Premiere CS6 (v. 6.0.5) and After Effects CS6 (11.0.2.11). When I export a clip with stereo audio from Premiere or After Effects (usually to ProRes or Uncompressed QuickTime), the resulting file will show as having dual-mono audio in FCP7. When I check the file in QuickTime 7, QuickTime 10, MediaInfo, Premiere, After Effects etc., the audio is tagged as stereo. But when I bring the clip into FCP7, the audio shows as two separate mono tracks.
While this isn't a problem if I stay within Premiere/After Effects, it does become an issue when I need to work with the clips in FCP7 (they have to be relinked as audio pairs in the timeline), and one of the external distributors I work with has come back saying the file we delivered did not have the audio properly linked as stereo.
Am I doing something wrong here? I don't want to have to workaround by putting everything through FCP7, as we are really trying to keep our workflow within the Adobe suite and retire FCP!

Hm, not from what I've seen. Anything that's been exported as stereo through FCP, Compressor, MPEG Streamclip, Episode etc. shows up as properly linked stereo in Final Cut.
I just ran one of my Premiere exported files through MPEG Streamclip to the same format (ProRes, uncompressed stereo audio) and it showed up as having a linked stereo pair in FCP7, while the original showed 2 mono tracks. I am definitely exporting from Premiere with the stereo option selected (and stereo source audio).

Captured stereo convert into Dual Mono

Hi all,
Some of the footage I have to work with is captured as DV with stereo audio tracks.
That's not so nice, because the audio is actual 2 mono channels (2 different mics on interviews)
I know I can switch off the stereo pair in the timeline. But that's tedious. I need to alter everyclip everytime I drop it in the timeline. Also I cannot Unpair the clip in the viewer, while I do need that because I want to lower the level of only one channel during chosing the quotes (because of wind in 1 mic for instance).
So it would be nice to be able to alter the master clips in the browser from stereopair to dual mono.
But I canot figure out how. Can this be done in FCP?
Can this be done in Quicktime.
Any ideas.
thanks
Rienk
NB (I know how to set up dual mono in Log and Capture. It's just that 10 tapes, that someone else did capture in stereo, and I need to work with)

UODATE:
Just opened one of the good clips (captured as DUAL Mono) in Quicktime. Then I see 2 seperate soundtracks. Sondtrack 1 with one ch1 set to MONO and Soundtrack 2 with one ch1 also set to MONO. It that way it differs from the two channels in the one Soundtrack 1 in the clips that were captured as Stereo.
Export the original masterclip from FCP with Export using QT conversion. and set it to export 2 discrete channels will indeed create a file with 2 Mono cannels. And they import as such. "2 Mono" it says.
Reconnecting the master clip to the newly created Dual Mono clip let FCP still think this is a stereoclip (As Andy pointed out, this is indeed not working)
Reconnecting the sequence clips to the newly created Dual Mono clip seems to work. But when I do match frame, then there comes again a stereo-version of the clip in my viewer. (also of course this is because it is looking to the original masterclip that we cannot change in FCP, as we saw in the previous sentence).
So I found a way to create new Dual Mono masterclips, but still I'm not able to alter the originals to the sequence clips.
The building will close here. So have to leave.
But I will try if I can change the settings of the masterclips from within an XML...
OR the solution would be in QT to split the two channels in two soundtracks in Quicktime... But how?

Converting clips to dual mono

I'm trying to convert HDV clips shot in stereo into XDCAM HD clips that will support write-back to my Sony PDW-U1. But the U1 only supports "dual mono" audio, not stereo. I'm looking at the audio tab in my Compressor settings, and don't see such an option. I have Mono, Stereo, Stereo Headphones, and on and on. I'm currently running tests, but has anyone found a way to create supported audio for write-back to XDCAM devices that would be dual mono? Or is there a feature in FCP that I haven't found?
Chris.

This has to be done through Final Cut Pro. Not possible to do in Compressor yet.
Have a look at this article: http://www.larryjordan.biz/articles/ljmultaudio.html
"In Final Cut Pro 6 the Sequence Settings window got a new audio export option called Discrete. This option is used with the Export QuickTime Movie command. If you choose this option, each exported QuickTime audio track is labeled with the corresponding output bus number of your sequence."
http://manuals.info.apple.com/en/FinalCut_Pro_6_NewFeatures.pdf
Here is what I would try doing.
1. Make a sequence in FCP with dual mono audio and add your HDV material.
2. Choose File > Export > Using Compressor
3. Create a new QuickTime Movie setting with the XDCAM compressor you want (under video settings)
4. Set the audio to Pass-through
5. Select at destination and a name for your clip and hit submit!
If that does not work, change the sequence settings in FCP to the XDCAM preset you want, change the audio output settings, and add your HDV material. Render and output.

Combining dual mono tracks into single stereo

I may be brain dead about this and since I have been recording a client all day--a non-pro doing a VO--I am. I may not be using the search function very well either here or in the manual.
I am working on a 27 minute film segment in Logic exported from FCP using the XML function. Mostly that has gone well but is by no means plug and play. It is very cool to have the project based in Logic and be able to do all my audio and music in one environment to HD picture.
My quandary is this: I would like all of my dual mono tracks from FCP to appear as a single stereo track in LP8. Is it possible to "collapse" two tracks into one with out exporting, reimporting them and then re-syncing possibly?
This is a confusing project and the more I can simplify my organization the easier my life will be.
Thanks, eab

One easy way to treat the two mono tracks as one for editing a so forth would perhaps be to assign them both to the same Group. That way all edits, automation and such will be applied to both tracks.

Can't get a clip to behave as Dual Mono

FCPX 10.0.9 is refusing to treat just one of my clips as dual mono.
When I right-click, show in timeline, it opens in a timeline with a single audio track showing.
For all the other clips / projects, right-click -> show in timeline reveals two separate audio tracks.
This clip was shot in the same exact way as every other clip. In fact, it was shot in between other clips that work.
When i select the clip, the inspector shows Channel Configuration - Dual Mono, in both the timeline and the event browser. Same as all the other clips.
If only I could slip the audio separately in the project timeline - but if I try, all I can do is select part of the clip - I can "Expand audio components" and see the two mono tracks in the timeline... but if I try to move them, all I can do is select parts of the clip, whichever tool I use. Can't move them separately.
Here's what I've tried:
1. trashing and re-importing the clip.
2. trashing and recreating the project.
3. doing both of those together.
3. duplicating the clip and importing that into a project. (this solved the same problem for another clip, but doesn't work on the current clip).
4. Quitting FCP and restarting.
5. Setting the source clip to stereo, back to dual mono, then re-placing it into the project.
6. Waiting for all the background rendering, wavefom generating, etc (this solved it for another clip that was refusing to be dual mono).
7. Copying the camera card to the hard drive and importing from there instead of straight from the card.
8. Importing the clip with "separate mono and group stereo audio" checked, then again with it unchecked
9. Opening the clip in quicktime pro 7 and changing the audio channels from "left" and "right" to "mono" and "mono."
10 quitting, renaming the clip in the finder, and reopening FCPX
One thing I notice is that through all theses steps, FCPX never has to re-generate the audio waveform files for this clip. It is seemingly remembering the clip and using a saved audio metadata set of some kind, which I think prevents me from solving the problem...
Dang! I was so enjoying FCPX after a year of premiere pro. Thought 10.0.9 had ironed out a lot of bugs, but glitches are the worst thing ever.

Wow - hours and hours spent... no solution...
OK, when I "expand audio + video" in the project timeine I get...
Then collapse that, and "expand audio components"
Wow! Dual mono. And the waveforms are clearly different, indicating true dual-mono. But I can't seem to independently move those tracks; all my tools just try to select parts of the clip.
If I click the clip and "open in timeline", it looks as above, but I no longer have the option to "expand audio components."
So for a different example, one that worked without any trouble or tricks...
Then right-click, open in timeline...
Very different result. That clip was shot AFTER the non-working one. The clip I shot before works as well. The odds that I changed something on my camera for that one clip, and then changed it back...??
I went through all my camera switches and menus (HMC-150, shooting AVCHD) and can't find anything remotely relevant to the problem at hand.
Also, as I said in my list of attempts at solving, a couple of other clips had the same problem and it went away with solutions 3 + 6 above. So it's definitely, in my mind, a program glitch.

FCPX Dual Mono vs Stereo question

Hi everybody - I've been busy but recently on the Zumiez show I came out of it with a question:
I like to route each of my AJA KiPro ISO records two separate channels of audio, I send a line-feed to CH. 1 (left) and I run a NAT mic feed to CH.2, (right). If I bring the captures into FCPX, for example to create short lifts, I want the producer to be able to choose between the line feed or the ambient mic, so I leave them as "Stereo", but it isn't really a stereo track. I needed to adjust the levels, raise the line level and lower the mic level, but I can't do that unless I designate "Dual Mono". When I designate Dual Mono, I can adjust the levels seperately and even apply filters indivisually, but then the channels are summed mono.
How do you keep stereo seperation on two individual tracks and still be able to make individual adjustments? Or maybe another way to the same goal; can I set hard pans on a pair of Dual Mono tracks?
Thanks for any help! -Stephen

How do you set different volumes on dual mono?

I'm missing something, I'm sure, right? I normally record a mic to a channel and NAT sound to another channel - so say for example, I might mic up a presenter on stage, and take that feed into Channel 1 (external source) and leave my on-cam mic set to internal for Channel 2 - so I can bring that up in the edit for either Q&A from the audience or just to swell applause. In FCP7 audio tracks showed dual mono as two tracks with individual overlays so you could adjust each channel as needed. In X I only see a single track of dual audio, and in the information box, I can check or uncheck the channel I want - and a lot of times, that's good enough, but how do you keep both channels and adjust the volume of each one seperately?

Tom - thank you. So to make sure I am clear though, (my audio was always dual mono, and in the inspector they are represented as two seperate tracks where I have the option to check or uncheck each one), but the timeline, they appear as a single track and in your solution (which worked) you are saying to break apart (as in make them seperate from each other and able to fall out of sync? that kind of break apart?) it still worked I was able to see two tracks, similar to FCP7 - and I can adjust volume seperately on each channel, but are they no longer linked in terms of sync? If I am understanding correctly, then is that to say there is no way to keep their connection to the video they belong to and also still see each channel and adjust each channel independently of the other?

How do you export 4 discrete mono audio tracks with video from Adobe Premiere Pro 4/Adobe Encoder?

I've posted this question in different terms a few times and have not had an answer. I can't find the answer on the Premiere Pro support site either (which makes me think that a simple solution doesn't exist)
We use adobe premiere pro 4. We capture DVCAM tapes with 4 discrete audio channels. When we export the video using adobe encoder, the result is stereo tracks with the discrete audio channels mixed together which is completly useless to us. When I select Mono for the output settings, two channels of audio are mixed into one audio channel. Also useless.
When capturing the clip, we always use the mono timeline and modify the clips to mono. We can edit the discrete audio channels but when we export the video, the audio is mixed down.
this is the problem. Each of our 4 audio channels contain a different language of dialogue. When exported, these 4 get mixed down to 2 mixed channels blending of course the language.
Can Premiere Pro 4 export discrete mono audio channels? How do you do it?
Does version 6 have the ability to export 4 discrete mono channels?

Hi Steve,
Important info is missing from your post - what format are you wanting to export to, and for what purpose? We need to know how the exported file is intended to be used. Who's going to view it, using what gear? Is it for another editor to work with? End user viewing?
Thanks

How do I import stereo audio as pan centered, "Dual Mono?"

Greetings,
For most of my video recording, I’m running two wireless mics and am recording in stereo.
90% of the time, I’m working with one track or the other and, because I’m cutting for broadcast news, the pan for the audio needs to be centered.
Is there a way to import the audio I recorded in stereo as Dual Mono with the pan for each channel center?
It’s a pain to have to go through each clip and make it Dual Mono and then chose Pan Mod Default to center it.
I bring in my video as indiviaual clips so I can’t select a single clip in the Event Panel and make my changes for the whole project.
Regards,
Steve

Select the clips in the event, and set the audio as [Dual] Mono!
There is, as I remember, no option for this during import - but you can select multiple clips and set it on all at once.

Multichannel audio downmix monitoring / "Map to Dual Mono" disengages when working with another sequence

I typically like to edit with multichannel / mono audio channels, but monitor audio with regular speakers by way of downmixing. I found the useful "Map to Dual Mono' button in the audio track mixer which allows one to monitor all the split channels mixed. The problem I've encountered is when I switch from the multichannel sequence I'm working in over to a regular sequence with other audio settings, and then go back to the multichannel sequence that I started with. When I do this, the "Map to Dual Mono" button disengages, and I'm not able to monitor the audio in the mixed way I'd like. After pressing the "Map to Dual Mono" button, everything's o.k. again.
Is there a way that once the "Map to Dual Mono" button is activated, that it stays activated, without having to re-press it again and again?
Here's a video description of my audio monitoring question: Adobe PP CC downmix disengages - YouTube

mmmm this is an odd one... the only thing I can think of is that you are changing these clips once they're in the timeline. It's done with a keyboard shortcut: option+L... it will change a dual mono track to a stereo pair. You can change these files back though... typing opt+l toggles the condition back and forth.

Audio Meters view in Dual Mono configuraton

Can't understand why, setting a clip in Dual Mono configuration in the event browser, FCPX set the Audio Meters window in Mono view
whereas the same clip put on the timeline set the Audio Meters in the normal stereo view
It didn't happen in previous FCPX versions

IIn the browser the meters are looking at the clip. In the timeline you're seeing the meters for the project, probably the default stereo.
