Replacing an audio track without re-encoding the video

I'm new to Audition CC so apologies for the basic question. I originally asked this in the Premiere Pro forum but I think it's more an Audition question..  I have AVCHD home video (MTS video with AC3 stereo audio) and have found I can clean up the audio, for example in speeches, very well in Audition. Is there a way to just replace the MTS's orginal audio track without re-encoding the video (which it seems I have to, if I do this via Premiere Pro)? In some cases the videos are poorly lit and any re-encoding makes them look noticeably worse than the original. In any event the video does not need re-encoding, I just need to replace the audio. Maybe I need to export the cleaned-up audio from Audition and use some other program to replace the audio in the original MTS file? Is that called re-muxing?  Thanks in advance for any help.

Thanks Bob and Ryclark.
  Bob, our aim is to copy these videos onto USB sticks, for our family to watch on our various home TVs, from a media player such as WD Home TV, a media PC or a laptop via HDMI cable. I expect the original MTS files, with cleaned up audio, will be fine. Media Info shows these to be video: AVC format, variable bit rate, 16.0 max bit rate, 1920x1080 pixels, 25.000 fps, 8 bit, interlaced; audio: AC3 format, 256 Kbps bit rate, 2 channels, 48.0 KHz sampling rate, 16 bits bit depth. I'm keen to avoid re-encoding the video, and it seems I can. My initial test worked and tonight (I'm in Australia) I'll test further... I can edit the AC3 audio in Audition, export it as a new AC3 with the same format as original, then use some other non-Adobe program to replace the original audio track with the new one, without touching the video.
  Ryclark, I believe you are right. My novice-level understanding is that the process of separating the components of a video file such as my MTS file (video, audio and possibly others) into separate files is 'de-muxing' and putting them back together is re-muxing. Audition can save or export the original or edited audio track of my MTS file to a separate file so I assume that's like a specific audio de-mux. However I don't think Adobe products can re-mux without re-encoding the video (slow, larger resulting file size, worse video quality!), so I need some other program to replace my MTS file's audio with the new/edited audio.
  So far I've found the free-ware Avidemux can do it but past experience is that free-ware can be a bit flaky or over time not as bullet-proof as a good/proven commercial product, so I'll look a bit further - or does someone in this forum know of such a product? HD Video Converter seems to be an option but it looks a bit amateurish.
  By the way, if anyone is after a cut/join program to remove unwanted parts of a video without re-encoding the whole thing (ie. fast, same file size and unchanged video quality) I found Avidemux (free) only works on whole frames (GOP?) and the joins can have a little 'flick', whereas for $40-$50 a program like Fame Ring Smart Cutter for MTS videos (the Sony vidcam home video files I'm interested in) is frame accurate (it only re-encodes around the cut points) and works very well (smooth cut/join points). Smart Cutter doesn't do AVI videos (for my PC screen-recording videos) but I found SolveigMM Video Splitter Home Edition works well with those (not so well with my MTS files).

  • How do I get the audio track to stick with the video track?

    Whenever I move or cut the video track I want it's audio track to move or cut with it, how do I get them to stay together so I don't have to do double work?
    This should be an easy one...Let's see who can answer first.....ready, set, GO!

  • Can't add a new audio track without any settings

    Can anyone tell me were faced with the same problem. Doing audio post production in Logic Pro X, the latest version, the project is big, At some stage the work I was faced with the fact that you can't add a new audio track without any settings, no matter what inserts I track with duplicate settings of one of the tracks and it begins to sound with this track. I don't add a new audio track with duplicate settings. I add a new one, and I still opens the track with some sort of settings. What is it? This is a glitch or I'm somewhere that we have not considered? Duplicates the configuration of one of the tracks collected in group 1, which I did for editing convenience. Duplicates and also automation and if the new track am I doing something then this machine is transferred to the existing track from this group.

    Everything works in full 'Logic Pro X' mode. It's just a glitch in my project. The problem while you decide this: I insert a new track and it reset and set the output.

  • How to add an audio track without scaling?

    I have a 3 minute audio track that I want to add to at a beginning of my 4 minute video clip. I "select all" from my audio mov file, I switch to my main video mov file and the insertion head is at the beginning. When I select "Add to movie" my movie file is now 7 minutes long. The picture is frozen at the beginning of the movie for 3 minutes while the audio is playing...
    I tried moving the insertion input and output and used the "add to selection and scale" command, but it distorts the audio file since the audio file is actually a few hundredth of a second longer.
    Is there any way to copy-paste an audio track without scaling?
    What I want in the end is a 4 minute video clip with just the first 3 minutes with my audio track.

  • How do i mute an audio track without deleting it.

    how do i mute an audio track without deleting it?

    There have been a few recent posts, where Audio Mixer settings are not "held," in PrE 11. Those cited problems seem to be Project-specific, in that Audio Mixer works, as expected, in a new Project - just not the one, causing issues.
    I do not know if there is a glitch/Bug in Audio Mixer, or if the users are doing something that is "disconnecting" Audio Mixer in some way.
    As a test, create a New Project, Import a Video file with Audio (Muxed Video Stream and Audio Stream), and test Audio Mixer, and the Mute function there. How does Audio Mixer work in that Project? Does the Muting of the Audio "stick?"
    Second test: in your existing Project, Select all the Clips on that Audio Track #1, and drag them to Audio Track #2, or another, empty Audio Track, and test the Mute for that new Track, in Audio Mixer. How does that work for you? Does the Mute stick?
    Good luck,

  • Using Pro Logic X to record. I have several tracks and I'm trying to record an audio track. I have the mic connect to Avalon 737 then into apollo interface. When I record all track are being recorded into that track. I can't just get the audio to record.

    Thanks for responding. Everything seems to work right except for the when I plug into the 737. Ok let me see if I can be more clear. I had this set up done with two representatives of Neumann, and DBox. Here it is I hope this helps. 32 Channel snake (24 Inputs 8 outputs) Channels 1-8 from snake to my Octopre for Drums. From Octropre output quarter inch lines into the Apollo 2, quarter inch input. This is so that the Apollo 2 is taking the drum tracks. Snake Channel 9-12 into Apollo 1 channels 1-4 xlr. Snake Channel 13-16 into Apollo 2 Channels 1-4 xlr. Snake Channel 17 into the 737, output of 737 into Channel 5 of the Apollo 1 quarter inch.
    Ok The Dbox. Sum output L&R into channel input 7&8 of Apollo 1. Apollo 1 output channels 1-8 into summing input channel 1-8 of Dbox. Apollo 1 main L&R going to main analog input L&R of Dbox. Spid out to DAW input of Dbox. I have both ADAT of both Apollos connected by optical wire. Also have port 2 of Apollo 1 into port 1 of Apollo 2 connected by Firewire.  Let me know. Hope I got it right. Thanks for responding.

  • Recording through the Mac Audio Tracks rather than through the Mic.

    I figured this would be very handy since I'm just recording the sound from a YouTube video, I don't want to have to use the mic to record the sound, If it's possible to save the Mac Audio Tracks, which is basically anything that comes out of the speaker, to a file to be used by Garageband later? Or is there a way to record, not through the mic, but using the Mac Audio Track through Garageband? It would help because I realized when I recorded through the mic that I had to worry about everyone around me being quite for a few seconds only to realize that the fan was running full boar which made the quality terrible. Just looking for an alternative. Maybe a program that records the Mac Audio Tracks? Sorry for the long-winded post.

    I know a way around this as I had the same problem once. I bought a small lead with stereo mini jack to stereo mini jack which enabled me to connect the headphones socket to the line/mic in socket. This means that any sound your computer makes can be recorded directly using any recording application, including Garageband. No fear of extraneous noise as it is a direct connection not microphone. There may well be a purely 'software' method also but I can confirm that this does work anyway.

  • I have a m-audio producer usb microphone and since the update on Dec. 22, 2013 Logic hasn't been allowing me to record with it. Logic is reading the microphone as the input but the audio tracks don't have the record enable button. What's wrong?

    I have a m-audio producer usb microphone and since the update on Dec. 22, 2013 Logic hasn't been allowing me to record with it. Logic is reading the microphone as the input but the audio tracks don't have the record enable button and won't let me select an input for the audio track on the inspector panel. What are some possible solutions.

    Certain M-Audio USB devices (along with some other USB2 class compliant devices that don't use drivers) no longer work with Logic Pro X 10.0.5
    At this time it is unknown as to why this has happened. Nor is it known if Apple will need to fix it or if it is up to the Developers of said USB2 devices  to remedy the problem.
    In the mean time, assuming you made/could make backups prior to updating to 10.0.5.... the solution is to roll back to LPX 10.0.4...

  • I have a keynote presentation that includes a significant amount of video.  When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)?

    I have a keynote presentation that includes a significant amount of video.  When I edit the keynote slides (not the video slides) how can I save the changes without re-saving the videos (because that takes a VERY long time)?  I edit the presentation depending on the audience to which I am presenting.

    If you add a new  slide with just a text box (therefore a very small amount of data),  to an existing presentation then save,  Keynote will only save the new content to the file,  it wont save  pre-existing content as its already included in the file.
    The time  taken to "save" will be very much shorter than a "save as" when all of the existing content is saved again.

    Thanks for the reply.  I tried playing with detaching the audio in iMovie, but with 20+ hours of video to correct, it would take too long.  After 28 hours, Corel/Roxio tech support replied that it is a known bitrate mismatch problem and they have no real fix.  I strongly suggest not to buy this product.

  • Has anyone else had a problem with the audio not keeping up with the video when switching to full screen on YouTube?

    Hi. I have a OS X Yosemite Version 10.10.1 Mac Book Air, Processor 1.86 GHz Intel Core 2 Duo.
    Has anyone else had a problem with the audio not keeping up with the video when switching to full screen on YouTube?
    The video starts out fine, but if I click on the expand icon in the lower right corner of the screen the audio won't keep up.
    Refreshing the page don't help at all. In fact, nothing seems to help once it starts.
    I did not have this problem at all using Mavericks. The problem started after installing Yosemite.
    Any way to fix it?

    only $99, i thought it was closer to $175.

    OK. I misstated this. I have a number of Smart Mailboxes with their specific rules in which to route certain topics to specify mailboxes. I am trying to not have to create each Smart Mailbox on each computer.
    The problem is that when I am on the road I add contacts, bookmarks, keychain items, contacts into my laptop and vice versa when home. I would just like to have those Sync on both computers. Seems like it should be easy, but it hasn't been.
    I really don't think I have anything "non-standard." A few Smart Mailboxes, a couple of signatures, thats pretty much it.

  • I am trying to import video and the audio doesn't upload with the video. Help.

    I am trying to import video and the audio doesn't upload with the video. Help.
    I upgraded to iMovie 11 because the previous version wouldn't read the type of video I was importing (VOB).  The video imports but not the audio, what do I do?

    What are you capturing from?  You may not hear the auido as it's captured but it will be there.  After it's captured can you see the audio waveforms? Do the audio meters move when you play the clip?  If so then go to "View" then "Audio Playback"  and set it to 'Built-in Output" if you're monitoring audio through the computer.

  • Is there a way to re-compress the audio of a clip without re-exporting the video?

    Hey guys, I have 500 clips that took me 2 days to render to ProRes just to find out that the audio is not the right format. What do i do now?
    I don't want to have to re-export all those 500 files again and wait 2 more days. Is there a way to run those files through an application (either in compressor or something else) that will re-render the audio in the right format without doing anything to the video?
    I know how to swap the audio of a file using QT Player 7 but I only know how to do that one file at a time. Obviously, I wouldn't even think about doing that 500 times... I'll go nuts.
    What are my other options? Adobe Media Encoder? MPEG Streamclip? VLC? Anything at all?
    Any help is much appreciated

    Well this workflow should work but I don't know if there might be problems down the road.
    Bring all your prores files with the problem audio into compressor.  Apply the audio 48k16 bit preset to them.  This will create individual aiff files with fcp friendly settings.  
    Bring the resulting aiffs into fcp.  Select the video qt and audio aiff in the browser for one clip and control click on one of them and choose merge clip.  This should create new clips with the good audio as channels 3 and 4 (assuming the original files have 2 channels of audio). 
    You should then be able to edit the merged clip into the timeline and by just patching channels 3 and 4 (the 48k16bit audio tracks)  into your timeline and unpatching channels 1 and 2.  , you should not need to render the audio.
    Try testing this workflow on one clip and see if everything works before doing all of the clips.
    If any of this is not clear or you need help with any of this, post back.
    Frankly, you might be just as easy and safer to reconvert all the clips with the audio enabled to 48k16bit in compressor.    You could also edit each clip into it's own sequence, replace the ng audio with aiffs made as I described above and then export reference quicktimes to edit with.
