Exporting files with AC3 audio

Forgive me if this is not the right place to post this question.
Using QT Pro, I want to trim and edit some files containing AC3 (Dolby Digital) audio. When I export or save the edited video, will they retain the AC3 audio?
More specifics: These files contain both AAC audio (in the default track) and AC3 audio (second track). These files were encoded using Handbrake, and I will be playing them on my AppleTV (hence the desire to retain the AC3 audio). The source files come from my DVR, and I want to trim some commercials. I tried to trim them prior to encoding, but I'm having trouble finding reliable software for editing MPEG2 streams on a Mac. Thus, I'm trying to figure out whether or not I can trim them afterwards using QT Pro and still retain the AC3 audio.
Any thoughts would be appreciated. Thanks!

Aaah, I wish I could help! I have exactly the same problem! I was going to post about it, but since there's this workaround, I didn't want to take up bandwidth with a problem that was not a total showstopper.
Indeed. I have stopped doing what I used to do before. Before, I used to select "All" in compressor - the files generated were the video, the aiff, and the ac3. Well after burning a few coasters through DVDSP 4.1 where there was picture but no sound, I realized that I needed to drag the aiff file to compressor again, and use that - at that point everything is fine. So, right now, my workflow is to export just the video from FCP through compressor, let it encode. Then export the aiff separately and encode it to a3 in compressor, then import the video and ac3 to DVDSP for good results. In short, no more exporting "All" from FCP through compressor, it's a waste of time.
But as to why, I have no idea, and I'm eager to hear what folks have to say! Anyhow, just letting you know you are not alone. Btw. my set up is: FCP 4.5 HD, compressor 2.1 and DVDSP 4.1.0... what's yours?

MPEG-2 file with AC3 5.1 audio: no audio (neither in current video playback, nor after encode), but plays okay in QuickTime X

Mavericks 10.9.3
Latest Mac Mini, 8GB RAM, two 256GB SSD
Compressor 4.1.1
I have an MPEG-2 file with AC3 5.1 audio which plays in QuickTime X as expected.
I have a second MacBook Pro with Compressor 4.1.1, where the audio is fine - both as current video playback of the source, and post-encode using Apple Devices HD (best quality) setting.
However in the Mac Mini Compressor there is no audio (neither in current video playback of the source, nor after encode using Apple Devices HD (best quality) setting).
Troubleshooting
- main difference between machines is the Mac Mini has Elgato software (EyeTV and Game Capture HD)
- I've checked the QuickTime components are same on both machines, except for EyeTV audio component on Mac Mini
- there are no plug-in audio components
- I've repaired permissions using Disk Utility
- I moved Compressor to trash, deleted compressor plist files, and reinstalled

Exporting 5.1 ac3 audio from Premiere Pro CS4

Hi there,
I wonder if anybody can help me out with exporting 5.1 ac3 audio from Premiere CS4 version 4.1.0?
I have a 3min long HD 5.1 clip that I need to cut down to 60seconds and add fade transitions to. The final clip will be used in a media player with very specific spec - the clip needs to remain HD 1080p with a frame rate of 29.97 and a maximum CBR of 38. The audio must be 5.1 aac. The format can be mpeg 2 or h.264. The overall quality loss needs to be minimal.
Up to now I have been cutting up footage that only needs to be stereo and I found the best way to to this while keeping quality was to use Prem Pro and export as mpeg 2 1080p 29.97, quality:5, bitratre: CBR 38, audio as mpeg layer 2 (as these clips were stereo only). These clips played back fine and looked great so I wanted to keep the 5.1 clip process as close to this as possible.
So far all I have been able to get from Premiere Pro is an audio codec called DVD_LPCM which the media player will not recognise. I'm a bit of a novice when it comes to 5.1 audio so I may be doing something obviously wrong...
- I have purchased the 5.1 surcode codec and its activated.
- I have started a new AVCHD (I need 1920x1080) 1080p 29.97 project with a 5.1 audio master
- The orignal file is an mpeg which I have pulled into PPro and selected Clip > Audio > Breakout to mono
- I take the 6 mono channels in the project panel and put them into thier own mono tracks in the sequence.
- the video I use is the original mpeg with the 5.1audio muted in the sequence.
- When i select each track in the project panel and go to Clip > Audio > Source channel mappings, I see that track has already been allocated a source channel. So I go to the Audio Mixer panel and adjust the 5.1 panners for each tyrack according to what the Source Channel Mapping window has told me - Audio 1 is is L, audio 2 is R, audio 3 is LS, 4 - Rs, 5- C and 6- LFE
- I cut the video and all the mono track to the 60seconds I need and export using these settings:
Video - exactly as before
Audio -
Format - Dolby Digital, Codec - SurCode, Audio Coding Mode: 3/1 (L, R, C, LFE, Ls, Rs - 5.1 Surround), LFE: on.
The clip exports with DVD_LPCM 5.1 audio. Is it to do with the AVCHD preset? Could anyone help me get aac? Any help would be appreciated.
Thanks in advance

Using AME and the SurCode Plug-in, here's how the dialog screen looks for the Audio Tab in PrPro 2.0. It should be similar in CS4:
You do have the Minnetonka SurCode DD 5.1 SS plug-in, right?
Good luck, and hope that this is helpful.
Hunt
PS - note that in the screen-cap, I have composited the dialog box, as though it fully displayed, with no need to scroll it. Depending on your display, you may need to scroll, and your scroll bars will look different from what you see here - just ignore that part of it.

I need to output a PAL HDV project from FCP as a PAL DV file with 4 audio t

I need to output a PAL HDV project from FCP as a PAL DV file with 4 audio tracks - specifically one stereo pair to be t1&t3, the other stereo pair to be t2&t4. This is the standard way requested by an international distributor of tv programmes. I understand how to set the sequence in FCP to output 4 audio tracks - either 2 stereo pairs (1&2, + 3&4), or 4 discrete tracks. But how do I then output this as a QT file?
The manual tells me that to export multiple audio tracks, File>Export>QT Movie has it's Config pop-up menu in the Audio Settings area of the General tab of the Sequence Settings. Well, that's set for 4 discrete channels, but the QT export settings only allow for 2 mono or 1 stereo output, and that's what I get when I try it. What it says in the manual just doesn't happen.
Exporting via Compressor, on the other hand, has an abundance of choices of 4-track outputs, none of which are labelled as anything resembling 'discrete'. Would any of those 4.0 settings suffice? Or am I likely to get myself into difficulties further down the line? As I am monitoring for this task on a 2-track audio system, I cannot confirm exactly what I am getting when I use any of those settings.
Any advice would be greatly appreciated!
John

Call me naive, but I've not heard of splitting the stereo pairs like this before.
What broadcaster? (perhaps one of our EU regulars will drop in...)
You can do all sorts of pairing but it is coincident tracks pairing- eg 1/2 + 3/4
Sorry I can't offer anything.

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?

MPEG videos with AC3 audio in iMovie

Hi there,
Aplle seems to totally ignore AC3 audio streams (at least in MPEG videos)! Why?
My JVC cam corder records *.MOD files on its hard disc. Those files
are in fact MPEG2 files, but with AC3 audio.
Renaming the files makes them playable using the Quicktime Player, but
without the sound
MPlayer is able to play them correctly, but that does not help me,
because I want to use the videos in iMovie and iDVD.
I tried installing the 'AC3 Codec.component' (what is supposed to fix
the problem for AVI files)
and now I installed Perian, which does not do the trick either.
I can ofcourse use ffmpeg to convert the files, but that means a
quality loss and a lot of work I wanted to save by buying a Harddisk
camcorder, so I could skip the time consuming conversion from DV tapes
to mpeg.
I there anybody out there with a solution?

QuickTime doesn't like to play the multiplexed sound on mpg videos. The QT Plugin ONLY supports video playback and NOT the audio track of such content (as you have found out).
I suggest you look at VisualHub software ( http://www.techspansion.com/ ) to convert your files to DV. It works with my problem mpg-4 files with multiplex audio. It runs in a free trial mode so you can verify it does what you want before buying it.

How to export file with original filename number suffix, but with more digits

Is there a way to keep the original filename number suffix, but change the formatting of the number, adding leading zeros for instance?
When I import photos from my camera I like to rename them, and give them sequential numbers, e.g. "2015-01 Hamburg 1.cr2", "2015-01 Hamburg 2.cr2", "2015-01 Hamburg 10.cr2", .. "2015-01 Hamburg 134.cr2", and so on.
Normally when I export photos I like to keep the file names exacly as I imported them (except the extension) e.g. 2015-01 Hamburg 1.jpg, "2015-01 Hamburg 2.jpg", .. "2015-01 Hamburg 10.jpg", .. "2015-01 Hamburg 134.jpg".
But sometimes I would like to export them with leading zeros, typically when adding photos to a web site or blog where there are sort mechanisms that only support simple sort algorithms based on file names, meaning the sort order of my photos with their original file names would become "2015-01 Hamburg 1.jpg, "2015-01 Hamburg 10.jpg", .. "2015-01 Hamburg 134.jpg", "2015-01 Hamburg 2.jpg".
So I would like the file names to be "2015-01 Hamburg 001.jpg", "2015-01 Hamburg 002.jpg", "2015-01 Hamburg 010.jpg", "2015-01 Hamburg 134.jpg".
By keeping the original file number suffix I can easily go back to the original file whenever I need to, and the sort order would work even with simple sorting.
The export Filename Template Editor gives quite advanced support for numbering files when exporting, see attached screenshot. There's support for exporting files with custom file names, and adding sequence, total and image number with padding (up to 9999/####). But those add new numbers, they do not consider the original filename number suffix. If I use the "Image # (001)" for instance, my example above would export as "2015-01 Hamburg 001.jpg", "2015-01 Hamburg 002.jpg", "2015-01 Hamburg 003.jpg", "2015-01 Hamburg 004.jpg", if those were the four photos I wanted to export, making it hard for me to trace them back to the original photo.
I have found no way of adding such padding on the original file number.
Does anyone know if this is possible or have suggestions for a workaround?
It shouldn't be too hard for Adobe to support this I'd imagine.
export pattern rename files file_number filename_template_editor

I do not know if you can do what you explained above, but there is a workaround to this (and a way to avoid having to do it in the future):
In the Library module, make sure your images are sorted by Capture Date (this will put them in the right order, even with suffixes like 1, 13, etc.)
Select all images, and then Rename them, using a Custom text followed by a Sequence number. The Custom text in this case should be the original name (such as, 2015-01 Hamburg, as in your example). Make sure the Sequence number is formatted with enough zeroes to include all the numbers in your images.
In the future, when you rename images during Import, make sure you select the Sequence number format that will include all the needed zeroes, so you don't have to go through this again.

QT H.264 files with two audio tracks. Quicktime plays 2nd track first. ***?

I've been experimenting with H.264 (AVC) and my DVDs. Using Handbrake, I ripped a DVD to MP4 (H.264) and including the director's commentary as the second track.
When I play the MP4 with Quicktime Player, it plays the director's commentary instead of the main soundtrack. VLC, however, correctly plays the first track (main movie audio track) and it allows me to select the second track via a menu.
To get Quicktime to play the proper track, I have to open "Movie Properties" and manually uncheck the second track. This was never a problem with DivX/XviD encoded files with two audio tracks; Quicktime Player correctly played the first track.
Why does Quicktime ignore the first audio track in MP4s (but not AVIs) and is there a way to correct this?

I do have QT Pro.
H.264 files are usually saved in a MP4 container. That's what Handbrake, ffpegX, and D-Vision create, anyway.
The "Choose Language" option is greyed out (unavailable) when I open this H.264 MP4 in Quicktime. If I try to change the settings in "Movie Properties," it says that I must save it with the .MOV file suffix.
It makes no sense to me that Quicktime Player can correctly identify the main audio soundtrack in a XviD file with an AVI container but not in a H.264 video with a MP4 container which Apple has been touting as the latest, greatest thing. Even VLC, an open source product still in beta, gets it right.

Can Premiere Pro CC handle AVI files with multiple audio streams?

I have an AVI file with two audio streams and I am wondering if there's any way to access the second stream in PP? So far I can only get the first stream to play. I know I can extract the second stream in for instance VirtualDub, but it would be nice to not have to do that in the interest of an effective workflow.

Hello again Jim! Thank you for your reply, you seem to be working hard here on the forums! The info I have found from 2011 suggested that it wasn't possible then, but I was hoping maybe they added this feature.

Just upgraded an iMac with 4GB Memory and Intel Processor from 10.6.8 to Mavericks and Quicktime plays m4v files with stuttering audio

I just upgraded an iMac with 4GB Memory and 3.33 Ghz Intel Core Duo Processor from 10.6.8 to Mavericks. I now have Quicktime 10.3 which plays m4v files with stuttering audio. This is a nightmare as I use Quicktime a lot in my research. I have seen similar threads but so far only reporting the problem. For now I have installed Quicktime Player 10.7 (which appears in utilities, leaving Quicktime 10.3 in the main applications list) which plays the same videos with no problem, but it would be good to know if anyone has managed to find a workaround at all, or know if Apple have plans to do anything about it?

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.

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.

Export QuickTime file with new audio and maintain the file size and quality as the original.

I shot some footage for a client yesterday and ran into an issue. To make a long story short I have QuickTime mov files shot with my Panasonic GH4 that have a buzzing sound in the audio track. I have clean audio from a recorder that can be sync'd. Is there a way for me to do this for the client and deliver them as the same QuickTime file but with the clean audio and keep the file size close to the original and not have quality loss in the image?
If so I will probably put all of the spanned clips together from each interview and sync the audio before delivery. I am just not sure which codec will give the client the same quality footage compared to the originals and not have a massive difference in the overall file size. They did request that they be Quicktime MOV files though so that is a must.
I don't see this as an option in the codecs in the export settings in PP, but is there a way to export as ProRes or another MAC native codec that will save them from having to convert it on their end? I am on a PC with Adobe CS5.5 so I am not too familiar with MACs, but from what I understand they would need to convert the files if I sent them straight out of the camera.
I found some related search results for this but they pertained to "Best quality" for export. I am not sure how the varying options work but I don't want to create files that are considerably larger, just not less quality.
If anyone has experience with this it would be greatly appreciated.
Thanks,
Cole

Here's the workflow: I imported the video footage into iMovie '08 and did my edits. Then I exported it (share) to my desktop with compression set @ 740 X 480. Then I used QuickTime Pro to fix the audio track. The file plays perfectly with both audio tracks working. It's a QuickTime file (.mov).
I hope this jars any replies as to why the file when uploaded to my iWeb gallery drops the second audio track.
Hmm,

Exporting QT file with multiple audio tracks

I'm trying to create a digibeta tape of my movie. The company who does it wanted a QuickTime file with the movie where there were 2 audio tracks (4 in sterio). One with the music and sound effects and another with narration and interviews. I'm not sure if this is possible or where to set the option for this. Can anyone help?

Command+0 (zero) to bring up Sequence Settings, go to the Audio Outputs tab and change the Outputs to 4 whilst keeping the Grouping as Stereo.
Back on the timeline, ensure your audio media is on the correct audio track for export, eg, all music on 7&8 , 9&10, VO on 5 and/or 6 , etc etc. Basically, keeping an organised timeline without spreading audio over random tracks really helps.
Ensure the audio tracks are assigned to the correct channels. To do this, on the timeline you see the 'destination buttons' A1 A2 A3 A4 A5 A6 etc etc... next to each button is a padlock, then you have the Toggle Auto Select icon. Control-click on this icon and you'll see the Audio Outputs setting, which shows which stereo pair that particular track is assigned to. In this case, you'll want to assign Music and Effects to 3&4, whilst keeping narration and interviews on 1&2.

Exported file plays wrong audio with slide

Hi all,
I just produced a tutorial in v2 that has sound files embeded
in almost every slide. They were originally wavs, but I have
captivate convert them to 64kbit mp3s. I also have some slides that
do not contain sound, but contain .flv files. (These .flv files
have sound.)
When I previewed the file, everything worked perfectly. The
sound cues were right, and the videos appeared just as they should.
However, when I published the file, the slides played completely
different sound files from other parts of the project and in the
wrong order. I tried exporting using both standalone .exe and
web-based formats using Flash 8, but the results were the same each
time.
Does anyone have any ideas about what could cause this
problem? Based on what I've seen, I think the three most likely
candidates for trouble are:
1) Slide audio errors
2) .Flv files
3) Flash 8
But there could be other, stranger things afoot.
Please let me know if you need more info about
something.

I tried re-exporting as an H264 mov but the exported file shrunk to 400 mb and lost most of the footage.
How do I fix?
I am guessing that you may have accidentally made a selection in the timeline before exporting - and then only that was exported.
Try exporting like Russ said.
And Russ meant to write VLC.

Export Video with Multiple Audio Tracks

I need to be able to export video with audio on multiple tracks. I have moved to CS6 from FCP 7 where this was rather easy to do. I can make a preset in AME with more than enough mono tracks but after the encode the video is always smashed to one mono track. I am not doing a 5.1 mix, there are different mic's on each track that need to remain independant of one another and mixing them down within Premiere is not feasable. Are there no options to just have the audio 'pass through' like Compressor? Sorry if there are other posts but I have been searching forever and can not find a simple answer on this topic.
Also, is there no way to have the source timecode burn in? Putting a filter on the video in a sequence is unacceptable, I am very displeased to find that this doesn's seem possible in AME or Premiere, it has been part of Apple's suite for years.

Hi James,
For exporting a multitrack .wav file, you have to start a project with a multichannel audiomaster (3-16 tracks).
Copy and paste your complete edit to the new editsetting.
Now in the audiomixer you can route your audiolayers to the multichannel you like.
(CH1+2 pan to left is channel 1, pan to right is channel 2 and for a stereo track pan to center : channel 1 for left and channel 2 for right.)
Then you export your project to a 3-16 tracks multitrack .wav file.
When you need mono tracks you can import your multitrack .wav file in premiere. Then send it to Audition (edit in Audition) and then adobe will convert the file into mono tracks.
You'll find the mono tracks in your audio capture folder or can premiere search for then by 'reveal in explorer'.
The multi track .wav file has got timecode within the file.
When exporting in QT you can also choose for a multitrack audio file. It also contains your timeline timecode.
.avi or .mp4 video files cannot be exported with more than 5.1 channels of audio
MXF OP1a in XDCAMHD can also be exported with max. 16 channels of audio. It also contains your timeline timecode.
Hopefully you can get further with Premiere Pro with this info.
Succes with it!!
