Merge audio tracks in QT Pro?

I have a .mov file (created by capturing video in quicktime pro with a video camera attached by firewire) which has somehow ended up with multiple audio tracks, all starting at different points. (How that happened is a complete mystery to me, but is kind of beside the point right now, though I wouldn't mind knowing that too). Each audio track seems to pick up where the last left off (as in, if you delete one, there is no longer sound for a certain portion of the video). I need to merge these tracks into one audio track, because Final Cut Express HD is giving me errors when I try to import these many-track files. I know I could solve it by just using export or save as..., but I'm really trying to avoid that if possible because I have about 20 clips like this, some as long as 5 hours, and that would take a ton of time and effort.
So, is there any way to just merge the audio tracks into one track, without doing an export?
Thanks!
Claire

is there a way to have alll 6 open and then combine or merge them into one file that I can play on ATV?
for this strategy, I would normally use the free MPEG Streamclip application. To begin, ensure the files are named alpha-numerically in the order in which you want them merged. Then open the MPEG Streamclip application and either "drag 'n drop" all six files to the work area or use the "Open Files..." File menu option to simultaneously select/open all six files. Lastly, export the merged file to the TV preset at the correct aspect ratio/dimensions and/or custom settings desired.
I have done the above but have a audio out of sync problem with it.
You could try pre-converting all AVI files to a common compression format like DV with the "Resample Audio to 48 Khz" and see if this prevents drift during the "merging" and final conversion process.

How do I normalise an audio track in Logic Pro

I would like to know how to normalise an audio track in Logic Pro X in order to increase the volume level to limit of say 0dB.

When you bounce your song out there is a normalise box you can tick.
No one really does it though as it has way more detrimental affects than it has positives. You can also do it through the sample edit window, if, for some reason, you wanted to normalise a single track in your multi track recording.
oh, ps, make sure you have all the advanced features ticked in Logic X preferences.

How to generate Mpeg4-generic hints to Audio track in QT pro version 7.2 ?

Hi,
By default QuickTime pro hints audio tracks with LATM option. Is there any way to generate Mepg4-generic hints to AAC-LC audio tracks with quickTime pro player ?
Any help will be highly appreciated. And am in need of this help very urgently.

Welcome to the forum.
For temporary unlinking, to edit, or Delete, just Alt-click on the muxed Audio Clip. Then, Rt-click and choose Delete, or hit the Delete key.

How to disable the audio track in QT Pro Movie Recording

I have a device that allows me to record DVI video (1900x1200 uncompressed) into QuickTime Pro through the Movie Recording function. It all works very well except I am trying to record video only (it's the video output of a medical device, so there is no sound). In QT pro preferences, the choices for audio input are "automatic", built-in microphone", or "line-in". I need the choice of "none" (at these files sizes I need all of the CPU's resources working on the video to improve continuity and frame rate). Does anyone know of a script to disable the audio recording portion, or how I might write one? I have never written script before, but that won't stop me from trying to learn how (or rather, launching into a prolonged period of trial and error).
I am also going to approach this by nagging the video device manufacturer, but they are more Windows- centric (they do support Mac OS X and some Linux platform so all hope is not lost). However, it would be easier if I could have more control over my own destiny, and Mac folk seem to be much more helpful.
Thanks in advance to anyone who may be able to help.

First, thanks for the quick reply.
Setting the audio option to line-in with nothing plugged in yields the same results. The device (which is essentially a continuous frame grabber) doesn't have any audio feed at all, and I think that is what is confusing QuickTime. The file I record generates one video track and several sequential audio tracks that start at roughly every 4 seconds. The movie info say that these are Big Endian Stereo L&R tracks, and that have virtually no file size to speak of. Audibly there is nothing. However, the constant "start over" with the audio is causing 2-3 second skips in the video. When the video is recording contiguously, the frame rates are on the order of 15 to 20 fps, which at 1900x1200 is fantastic for what I am doing (software training video of a Linux-based medical device; nothing cool like Snapz available for this beast).
By the way, I have tried Hack TV Carbon, hTV 0.2 and QT Broadcaster, all which will recognize the device as an input source, but not choose it. These would let me deselect the audio input. As mentioned, I am prodding the device manufacturer for help, too, so maybe they will come up with something to address this.
The other thing is that this device creates a video stream that is transferred by USB2. If it was a Firewire device, I would be all over this with iMovie HD or a HD Video recorder, and just be done with it. Apple may have to come up with some universal driver to accept USB video in since they have dropped FW on some of the new models, but this frame grabber isn't on the list as of now.
No real solution I can find to convert USB to Firewire.
Anyway, I am hoping that somehow I could get into the QT script and just disable the audio recording, like the old "save as Un-editable" script would pullout the "save" function of the QuickTime action.
Of course, dumping the audio tracks after the fact doesn't fix the video; once it's chopped up coming in...
I suspect that the real answer to this issue lies with the frame grabber manufacturer. But, I am still hopeful that the QuickTime Script writers out there (or the Terminal folks) may have something up their sleeves.
Thanks for noticin' me.

How do I merge audio tracks in Premiere?

So I recorded some gameplay using MSI Afterburner (x264 codec) and had it split my mic audio from the game audio as a separate audio track, to prevent the game audio from being muted whenever I talk. I used handbrake to transcode the avi to m4v, and the clip works in AE/premiere. When I load it in VLC, I can confirm that there are two audio tracks. My question is, where is the section in premiere that shows the audio tracks, and how would I merge them into one track?

If you have a clean signal on one channel, and the other is empty, you can use the Audio Effect>Fill Left, or Fill Right, to get back to two channel. Note, this will be 2-channel mono, and not true stereo, but will sound very similar, just without the separation.
Now, if you have one clean channel, but a problem with the other (bad Audio), I'd take the Audio portion of your File into an Audio editor, like Audacity, and strip out the bad channel, then just duplicate the good channel to replace it. That is basically what Fill-Left, etc. does, but if you have bad Audio, you will want to clean that out first.
Good luck,

White line across an audio track on premiere pro cc

In trying to access the waveform and volume control on a clip I don't know what I did but now there is a white line across the entire track preventing me from moving clips on that track - can anyone help me turn this off? thanks!

it wont show the waveform unless "zoomed" in enough. if this is the case for you, you can use the scroll wheel over the audio track (A1 for example), and scroll up or down to zoom in and out. its also possible to zoom in using the scroll bar handles to the right, at the end of timeline. make sure "show audio waveform" and "show audio keyframes" is turned on to see the audio waveform and volume automation line. you can hold down the ctrl key instead of switching to the pen tool, to create new points when clicking the white line. adjust as needed...

Importing audio tracks issue (Logic Pro 8.0.2 - Snow Leopard 10.6.0)

This is a strange one that i've only just noticed since installing Snow Leopard:
In Logic when looking for audio tracks via the media browser, I select a file and drag and drop it into a project. The file plays back in the project as expected, but...
A copy of the file is then placed in the location where i've just dragged the file from???
For example:
I navigate to a track within an album in my iTunes folder (stored on an external drive) and drag the track into an open Logic project. Once imported there is a duplicate of the imported file placed within the album folder. I'm pretty sure this wasn't the behaviour before upgrading.
There are a few weird things happening with this:
If I import a .mp3 file, a .aif file is placed within the album.
If I import a .m4a file, a .ovw file is placed within the album.
Sometimes it shows the copy of the track in the browser and sometimes it doesn't. If I navigate to the album location in finder there is a copy of the file located within the album folder.
Anyone else experiencing this?
Bryan

Cheers Bee Bee, school boy error on my behalf!
I was chopping up a few tracks to put on the mrs phone as ringtones and hadn't actually saved the session which would explain why a copy would have been put in the original location seen as there was nowhere else for it to go.

Multiple Audio tracks in Premire Pro

I have an interview that is done and now I'm trying to clean up the background noise in Soundbooth. I've done a good job cleaning it up but now how do I apply that same series of effects to multiple audio tracks in the same sequence? I'm currently just right clicking on the audio of the clip and selecting edit in Soundbooth>render and replace. But I have so many clips in my sequence it would take forever to do each one.
Is there a work around for this?
Thanks -

This may not be the only way, or best way, but if you have a bunch of clips in a row that all need the same treatment, you could export your Work Area as a .wav file, import and drop into timeline, then do the Soundbooth business on the new clip all at once.

No record button on audio track in logic pro x

Have you setup your audio interface in preferences? That would be the only thing I can think of as to why your're not seeing a record button.

Exporting merged audio tracks to audition problem

Hello,
I recently started to work with the Adobe suit so i am not yet used to the workflow. We are serval people working on the post production of a short movie filmed with a red SCARLET in raw which means that the files are pretty big. The audio where captured in serval tracks who all have been merged with the video clips. The clips have thereafter been cut and placed in its right place. So now it is my job to work with the sound design. I have tryd to export the audio in both AAF and OMF and every time i open it up in Audition it sais that the media is offline. On my computer all i have is the orgininal Audio files. Is there anyway to get only the audio (all the tracks) to Audition, without having them searching for the merged files. For example creating new Audio from the cutted tracks?

Have you tried this?

Transfering fcp 5 multiple audio tracks to soundtrack pro/ and 3 other ????

1. i wonder how to import multiple tracks from fcp 5 to stp and maintain these tracks in the multitrack format, not mixed down to two tracks.
2. i can't open a multitrack stp project i created in fce hd, into stp with fcp 5. i get the message, can't fine file??? when i click the file from the scratch drive, i also get the message that i need the apg ATI 9800 graphic card i used in my g4 with final cut express hd, but now i updated to g56 mac duel pro. do i have to att the ati card to my g5? and use this card instead of the g5 graphic card?
or can i use both the ati card with the gr graphic card, since i think that two graphic cards can be added to the g5?
3. i have a waveform file in stp that was made with final cut express hd, now i cant convert it to multi track, and i want to keep it since i filtered out background noise. how can i export it to fip 5 and reimport in into stp?
4. im a little bit confused about the mixer in fcp vs the mixer in stp. which is better to even out the sound from one sequence to another. also, to mix for tv sound, ( - 12 db), how do i do that with accuracy since the waveform varies... and jumps around from say - 15 db to -8 db? how does one find the average with consistancies, if possible.
i new to all this and would appreciate any help. thanks for any help any one can give me. ron hansing.

First up, learning STP is a great thing to do. You'll handle audio much better with it. Apple Pro Training Series, SoundTack Pro, by Mary Plummer, is the best way to learn it.
Back to your question. I did a basic tutorial that may help. It won't be out until December, but if you email me off board I'll send you an advanced copy of it. Shows how the work flow for editing multitrack sound from FCP into STP works. A bit to get into here, but it'll be a great start for you.

Turning on "record-enabled" audio track in premiere pro 5.5.

I'm trying to do a simple voice-over in premiere pro 5.5. I've followed all the instructions given in the tutorials yet I keep getting a prompt saying " You can't record because one of your record-enabled tracks is turned off? I know i'm missing something simple but can't seem to determine what it could be. Does anyone know what it might be?

I think this might help the discussion. I also have auto input monitoring selected. I can also hear the audio when I click the input monitoring button.

Error Playing back Both Audio tracks in Premiere Pro CS6

Hi, I'm going to make this fast and direct as possible. I was recording some media with DxTory (avi file output, default DxTory codec, an audio technica AT2020 microphone, and the media volume.) Both my microphone and the music from the audio; as well as the video played back fine in Windows media player, as well with other editing programs such as Sony Vegas Pro 12.
My problem is, when I import the file into CS6, only the video and sound of me talking shows up, the secondary audio channel isn't there. I used both PCM and MPEG Layer 3 codec for the audios (which played fine in other programs) but neither would play in Premiere.. Please tell me what do to, or if you need any extra information.

This sounds similar: Premiere CS5.5 Lost the audio for my voice but not the in game audio, I hear both in Media Player.

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.

Dead audio tracks generated after subclip created

I've had some issues relating to audio tracks in Premiere Pro CC. I'm currently editing a collection of shorts, shot on Red Epic at 5k, with a stereo guide track recorded to camera. After syncing the audio (4 channels), I removed the guide tracks then subclipped the vision and audio by selecting both, grouping them and then dragging them into a bin in the project window. Here's where it gets tricky.
When I place the new subclips on the timeline they suddenly have around 16 tracks of audio. So one track of sound, followed by 3-4 dead tracks with no sound, then 1 track of audio followed again by another 3-4 tracks of dead air (and so forth). At first I just saw this as a minor nuisance and continued to edit. Once finished I exported OMFs for the sound mixer who brought it into protools. What was a 16 track timeline in premiere has now become a 64 track project in pro tools. It seems again, each actual track of audio has had around 4 dead tracks added to it. Sure the math may be a little off but you get the gist. The issue is on Premiere's end as I've tried a couple of times now to resync the audio, create a subclip but every time it seems to generate a whole bunch of dead audio channels. Really can't figure this one out. Please help.

This exact same thing is happening to me. This "feature" is exponentially duplicating empty tracks. Clearly this is a bug in the code designed to break merged stereo tracks out into individual mono tracks. These are not empty stereo tracks. They are recorded as mono tracks with audio in them but being "split" into multiple tracks, one with audio and the rest are blank. The problem is that Premiere is treating ALL tracks as stereo and creating a number of new, empty tracks for EACH track equal to the total number of tracks when you use the Merge Clip feature.
i.e. If I have 3 tracks of audio that I merge into a clip, it creates 3 tracks for each of those three tracks, resulting in 9 total tracks (3 with audio and 6 empty ones). 4 tracks in a merged clip creates 16 tracks, 5 tracks creates 25, etc.
I have tested this with stereo and mono tracks in a merged clip and the results are the same. I got interesting results when I merged stereo and mono tracks into the same clip. I had a single stereo track and 5 mono tracks. "Merge clip" turned this into 27 tracks. 5x5 mono tracks plus the original stereo track that was split into 2 mono tracks, making 27.
HOWEVER
This phenomenon has not occurred on every single clip in the film I am currently working on; rather, it has only occurred on most of them.
Specifically, this only seems to be occurring when merging clips including multi-track .wav files. There were a few scenes where the sound guy only recorded the two actors with lavs onto a single stereo track, with the actors split between the L and R channel. When the stereo track is merged it correctly makes two mono tracks out of the L and R channels. But every single clip I have come across since then where he also added the boom mike or a channel for a third actor, I get exponential track city.
The conclusion I have come to is that Premiere is recognizing these multi-track .wav files as separate mono tracks when you drop them on the timeline, but the "Merge Clip" feature is mistakenly reading each track in a multi-track .wav files as a "single multi-channel track" that needs to be broken up. I say "single multi-channel-track" because there isn't a word for it that I am aware of. A single track with two channels is called "stereo" but it is like Premiere is reading the four mono tracks as a single track with four channels, but then making it worse by thinking EACH track has a number of channels equal to the number of "channels" it thinks are in the track.
So again, it reads each track in a four track clip as a single track with four channels, then breaks each "channel" into four separate tracks, thus creating the exponential increase in the number of empty tracks. (3 tracks become 9, 4 becomes 16, 5 becomes 25, etc).
Going into "Modify -> Audio Channels" is a lame workaround because I shouldn't have to painstakingly go through every clip in a movie just to manually turn off tracks that shouldn't exist. Presets, as suggested, are only somewhat useful because the positions of the real audio isn't always placed on the same tracks. Their location is also dependent on the number of tracks being created. When four tracks are merged, the audio is located on tracks 1,6,11, 16 while the audio for 5 merged tracks is on 1, 7, 13, 19, & 25, with 6 tracks it is placed on 1, 8, 15, 22, 29, & 36. So the only way for me to know which tracks to suppress on any given clip is for me to open up the clip and visually determine how many actual tracks there are and which ones to delete. This is crazy. To go back and fix this after I've synced everything will probably take me days of work. If I had known about this before I synced everything it wouldn't have been as hard to determine how many tracks each clip had as I synced it. But I shouldn't have had to in the first place. This shouldn't be happening.
This is not a feature, it is a bug. Period.
Clearly, this could not have been intentionally designed, but it is a serious and crippling error in the way the program is interpreting the tracks with the code that was intended to just break out stereo channels into mono. Perhaps it is a miscue between the way the recording device encodes the multi-track .wav file and the way Premiere reads it. I don't know. I do know that the audio I am working with was recorded on two separate professional recording devices by two different pro sound guys in Hollywood so this isn't some amateur mistake. It is easily doubling the amount of work I have to do with my footage/audio before I can start to work with it.
Somebody needs to take another look at that code and fix this as soon as possible.
(Does this make any sense or do I need to clean this up for clarification?)
