Audio missing on exported video

I seem to be having this same issue, time and time again.
When I export, no matter how I export the video (i.e. Share > Apple Devices, Share > YouTube, etc), the audio for the first multicam clip isn't there for the first 40 seconds or so. After that, it comes back in and plays normally. The weird thing is that background audio is there just fine, it's just the audio from the multicam clip.
I had Compressor 4 installed, but read that that could have been the problem, so I uninstalled it, but am still having the same problems.
Help - this is URGENT!

This seems to be an ok work-around. Didn't take as long as I thought.
Although a 4 minute video is still almost 2GB. Is that normal?
What are the best settings in QuickTime or MPEG Streamclip to export to for YouTube? How about for DVD burning in iDVD?
For iDVD, I would just use the master you already have. iDVD will have to compress it to DVD format. There is no need to do an intermediate conversion, that would add time and degrade quality somewhat.
For YouTube, it is likely that you *do* need to pre-convert, for two reasons: the file is too large, and the format might not be accepted anyway. The most obvious choice is to h264. It will likely be compressed again at their end. I am not sure as to what the best settings might be.

  • Some Audio Missing from Exported Movie

    I've exported a movie from iMovie to iTunes for sharing with AppleTV but the sound is missing from the last 75% of the movie when played back in Itunes or AppleTV. All the sound is ok in the iMovie project so some of it appears to have gone missing when exporting to iTunes.
    I have tried re-exporting it but it's still the same result.
    Any help would be appreciated.
    Regards

    Joe, I've also seen problems exporting iMovie projects with the Apple TV exporter, although never the problem you mentioned.
    I suggest you try another way to configure your own export settings. Your goal will be to create an export very similar to Apple TV, but build it on your own. The Apple TV exporter uses the H.264 codec, used for many other exports too.
    (You can test this on one or two clips in the affected area before exporting the entire iMovie project. Use the "Share selected clips only" checkbox.)
    Instead of choosing the Apple TV export in the export dialog window, try choosing "Movie to MPEG-4". Then click on the Options button. Configure these settings:
    UNDER THE VIDEO TAB:
    Video Format: H.264
    Data Rate: 2653
    Optimized for: Download
    Image Size: Custom, 720x480
    Frame Rate: Current (or 29.97 for NTSC, 25 for PAL)
    UNDER THE AUDIO TAB:
    Audio Format: AACV-LC (Music)
    Data Rate: 128 kbps
    Channels: Stereo
    Output Sample Rate: Recommended
    Encoding Quality: Better
    When the export is done, change the file extension to ".m4v", the extension used by Apple TV, if you like. You'll want to test the movie in whatever ways you now use the traditional Apple TV movie.

  • Audio levels in exported video [Premiere Pro CS6]

    The audio level is just what I want in the actual track. However, when I export the video the exported audio is too loud. So I went back and lowered the clip by 3dB...the volume level of exported video still didn't change--it sounds like people are shouting.
    This is a new problem...is there a setting in the export dialog box I have accidentally changed?
    Thanks in advance.

    I have found this to be a problem in CC at one of the places I work.
    Export at 16bit perfect levels with a tone ident...bring it back it into the project and now -3db.
    I tried exporting 32bit float and it comes out 3db higher!
    Only method I have found is to export audio separately to a 32bit file then in a new final video sequence, replace the audio timeline with this file and adjust levels. The new export seems to come out at the right levels
    May have something to do with a bug in the pan law but you can't adjust settings like in Audition.
    Many bugs in this program causing me nightmares....
    ....Can't save track preset effects and have to copy complicated track EQ and compression settings by hand
    ....Track effect settings adjustments that revert as soon as you click away or hit play
    ....Very slow with crashes and freezes in sequences with nested sequences.
    Leave plenty of time for your final exports...you will need it

  • Audio problem after exporting videos from imovie.

    When I export videos I've made in imovie, the audio becomes distorted. Clips that I have silenced, start to play during clips that they don't belong to. Any fixes?

    Hi
    How did You Export videos ? To what and into what format ?
    If to iDVD then
    • First I would trash iMovie pref files and iDVDs likevice
    • Then in iMovie - Share to Media Browser and as Large (Not HD or other res.)
    • Then in iDVD from Media button Movies import it.
    • Then test play in iDVD Preview
    • If OK then - Save as a DiskImage
    • Test this with DVD-player tool
    • Still OK
    • Then burn it to DVD either via iDVD or if You don't wat to re-calculate - use Disk Util tool.
    (set down burn speed to x4)

  • First four seconds of audio missing when exporting project as MPEG2

    Hello all-
    When I export my project from FCP (using version 6.0.6) using Compressor's (v. 3.0.5) MPEG2 Program Stream setting, everything works fine except for one slight problem: the first four seconds of audio are missing. I've looked back over my timeline (NTSC-DV with 4 tracks of 48khz 16bit audio), everything is fine, and the audio exported just fine using the H.264 codec. I've tried everything I can think of. Any suggestions?
    Thanks so much,
    Brett

    Well I REALLY need some help with this one! I have tried so many different 'work arounds' without success. As mentioned in my first post the audio is not sync'ing with the video when exported. I have tried Exporting the file in QuickTime, I have tried using Compressor again exporting just the video then the audio - pulling it into a new session and lining it up again but everytime I pull it the newly exported file into a new project and render it FCP crashes not allowing it to render (nice!). I actually started from square one capturing the video footage again and assemble the project again without luck. I simply cannot believe what a pain in the arse this is!! I need to get this project done and it simply won't do it.
    Where are my blood pressure pills????

  • Audio missing while exporting  an MPEG 2 with Compressor

    Hello There
    I exported a sequence from a video project in Final Cut Pro, using Compressor. While exporting an MPEG 2, I get no audio on the video file. What do I need to do so the Audio is embedded with in the MPEG 2 file?
    Thanks!

    If you want to make a DVD-Video, then you'll need to import both files into DVD-SP for authoring.
    If you want to make an MPEG-2 Program Stream or MPEG-2 Transport Stream, choose the appropriate DVD preset for your program length, duplicate the preset then alter the preset copy to make it produce a muxed (multiplexed) file.

  • Setting audio tone for exporting video (-12 or 0db?)

    Hi,
    I'm exporting a production as full uncompressed video to create a data DVD which will then be used to strike copies in different formats. I have 2 Q's.
    1) I'm prepping bars & tone at the head, & I noticed that the default setting for FCP HD 4.5 is to have audio tones at -12db. I'm from the old school of audio where tone was always set to 0db. I'm guessing that the higher dynamic range of digital audio makes some arguement for the -12, but I want to be sure.
    2) Also, its a music video. I'd heard the recommendation to have program audio levels peak at -6db to keep it from having unusually loud audio, but I'm wondering if that recommendation is for narratives & based towards dialog levels? Any issues with a music video having audio levels that peak at or close to 0db?
    Thanks a lot.
    Duane

    Duane this is an example of where old school is completely trumped by new school.
    In the analog world 0 dB was the point you wanted to be near at your loudest, and MAYBE peak over very quickly at the very loudest point of your track.
    in our digital domain these days, 0dB is now the point of no return. Hit zero and your track is distortedwith no chance of saving it.
    pretend that fcp's -12 equals 0 on an analog scale, and then imagine you've got up to -6 for headroom for the loudest things. NEVER go anywhere above -6 and you'll never have a problem.

  • Why is audio missing from MP4 video?

    I am using - - Adobe Premiere Elements 10, Windows OS7
    I have 11GBs of high quality (1.5GB = 15 min) mp4 video clips and I would like to edit and burn a couple of DVDs. When I import the clips they look fine, but there is no audio. (Yes, I have audio elsewhere on my computer and can hear these clips when I use any other player.)
    I tried converting them to .avi with Format Factory and I *can* hear them when I import to Adobe, but they are now "frozen" or "jumpy" and it is very difficult to navigate through the clips because the Play/Pause button has quite a time lag before responding.
    Should I convert to some other format? I'd like to keep as much quality as possible. I did convert them all to VOBs and made a "test" disc, but it dropped 11GB down so low that it will all fit on a 4.7GB disc. I'd rather make 2 discs and keep the quality up (though the one I made looks and sounds pretty good).
    Any suggestions would be appreciated. Thanks.

    Val8583
    Let me recap to make sure we are in sync on this.
    Knowing what you started with and the video properties as they evolve through needed conversion....
    You come telling us and demonstrating to us that you have source video
    AVCHD.mp4 (1920 x 1080 @ 29.97 frames per second) and that has MPEG1 audio.
    When you import that into Premiere Elements 10 Windows, you get video but no audio.
    The destination for that Timeline is NTSC_Widescreen Dolby DVD.
    In terms of setting the correct project settings, it would be important to know if you have
    interlaced or progressive video. But, since you not hear audio at that point, more
    important/pressing things to pursue.
    Aside from the pressing audio issue, at this point the choice of project preset would still be
    NTSC/AVCHD/Full HD1080i30 (if you have interlaced video)
    or
    NTSC/DSLR/1080p/DSLR 1080p30@ 29.97 (if you have progressive video).
    Either way, we need a 1920 x 1080 frame size project preset to match the 1920 x 1080 frame size of your source so that
    when you are in the Edit area you can edit your video in the correct space there. The final export setting is another matter. You
    should not be using a NTSC DV Widescreen project preset for a 1920 x 1080 video import.
    AVCHD.mp4 with MPEG1 audio (no Premiere Elements sound) to ????.avi with ???? audio (unstable in Premiere Elements but with sound)
    Conversion of the problem file sounds like a reasonable next step. And, you indicate that you do convert
    to an ".avi" file which has then has audio with the video in Premiere Elements 10, but the file is highly
    unstable in Premiere Elements 10. But, when I ask what video compression goes with the .avi wrapper, you
    wrote
    I just drag/drop the files to "Convert All to (whatever)" and the software does it.
    All .avi files are not created equal. And, AVCHD.avi, if that is what you ended up with, is highly unstable, and for most will
    not import into Premiere Elements. So, now the pressing questions include:
    a. what is the video compression and audio compression and other properties of this .avi file with the stability problems in Premiere Elements 10
    b. again, what are you setting as the project preset to match the properties specific to the source .avi.
    Now back to the present
    If you use Format Factory you should have control over your conversion settings. AVCHD.mp4 is a stable format for Premiere Elements. I suspect that the MPEG1 is problem. So, we agree conversion is the way.
    I would suggest taking the time to set the settings for your converter so that you produce AVCHD.mp4 (1920 x 1080 @ 29.97 progressive frames per second) and use AAC Stereo for the audio. Then bring that file into Premiere Elements 10 with the project preset of
    NTSC
    DSLR
    1080p
    DSLR 1080p30@ 29.97
    and proceed, ending with the Share/Disc/DVD disc with preset = NTSC_Widescreen_Dolby DVD.
    Since this project is destined for DVD-VIDEO widescreen on DVD, you could use your converter to produce NTSC DV AVI Widescreen and then import that into a Premiere Elements 10 project with the project preset =
    NTSC
    DV Widescreen
    and proceed, ending with the Share/Disc/DVD disc with preset = NTSC_Widescreen_Dolby DVD.
    As for disc capacity, the standard DVD disc 4.7 GB/120 minutes is in reality 4.38 GB. And the DVD disc double layer single sided 8.5 GB/240 minutes is in reality 7.38 GB. When you get to the burn dialog Quality Area (just before you hit Burn), look to see the values for Space Required and Bitrate (have a check mark next to "Fit Content to Available Space"). If you see a Bitrate reading below the max 8.00 Mbps, then go to the DVD double layer single sided disc or use two DVD standard discs.
    Do your intended viewers have players that support playback of DVD double layer single sided discs?
    Please review.
    I will try to make the reply not so long next time. I wanted to cover all the bases this time.
    We will be watching for your progress.
    Any quesitons or need clarification on anything, please do not hesitate to ask.
    Thank you.

  • Extra Audio Frames When Exporting Video

    Does anybody have the issue of extra audio frames being added when exporting a video. Every time I export, the audio adds like a 2 second handle. Very strange.

    The best advice is to tell them their work is coming back non-compliant and you can't have that.  Let them figure out why and solve it.  (That's is part of their job, after all.)

  • Audio missing  after export

    Hi
    Im having a new problem with premiere:
    I have a timeline of about 40 minutes long with several audio tracks and sounds, some mp3 from you tube and some recorded on the shooting day.
    everything sound just fine in premiere, I even exported one part of the timeline as a seperate movie and it was o.k.
    the problem is when I've import the hole track some of the audio tracks were missing/silent. it happend in 2 different projects.
    I'm on windows 7 premiere cc update to latest version...

    I've seen a couple of others report the same, but I have never seen it myself, nor have any ideas as to why.
    You might try a forum search to see what others have said.

  • Audio missing from imported videos?

    I am fairly new to using iMovie, so please bear with me if I have no idea what I am talking about!
    Audio is fine when I playback videos in Quicktime prior to import, but once imported to iMovie, there's no sound. I haven't changed my methodology at all, and this used to work, then one day, no dice. The only thing I can think of, is that I was "experimenting" one day, and selected "Extract Audio" from the right-click drop down menu. Now that option is greyed out. I have a feeling this is my problem, and that I somehow activated something. Any ideas how to "de-activate" it??
    Thanks in advance!

    Well, I went back and tried your advice. The conversion to .dv went fine, and when I imported that file into iMovie, voila, there was audio! But alas, once I added my title slide, and exported as Quicktime, audio was once again gone. Sigh. Any more advice would be so appreciated...

  • Audio not in exported video

    When I try to export a video from a .mpg file to any other file such as mpeg4, quicktime movie, etc., the video exports without any sound. How can I get the sound to export WITH my video?

    I'm just bummed I spent $30 on Quick Time pro just for that reason when I could have used the program you showed me for free!
    "Be of Good Cheer!" While QT Pro will not edit/convert multiplexed audio as you had hoped, it still can do many things that MPEG Streamclip cannot do. For me, this includes the layering of video for picture-in-picture or multiple window effects, the merging of video with static backgrounds, scaling of individual video/image tracks, the addition of custom logos/watermarks, etc. Basically, you have lost nothing and gained the ability to do many things that even the iMovie video editor cannot do without spending "bigger bucks" on Final Cut Express or Final Cut Pro.

  • Audio missing after exportation

    I exported a 8.5 miuntes film (cmd E, video codec:actual settings). When I run it with Quicktime player (10.0) everything is ok, but after approx.7 minutes the sound has sudenly disappeared. I use FCPX 10.0.1. With version 10.0.0 I never faced this problem.
    Does anybody know how to fix this ?

    I'm work on a PC, but in years past when on rare occasion my audio was somehow messed up in the final export, this has worked for me:
    Export the timeline as AUDIO ONLY. I used .wav format on the PC. Then Import that new .wav file and drop into an empty timeline track. MUTE all other audio tracks. Check the audio - if it is all intact and good, you can now export the video with the good audio
    Thanks

  • Audio Missing When Exporting to Flash

    When I export this Keynote presentation to Flash, I get an error message that says "Can't export an audio file because of an unknown error." Then it says that "Couldn't export a media file on slide 1" and so on for all 10 slides. It's basically a presentation that only has 10 slides, but audio that lasts about half an hour.
    Each slide has an audio file dropped on it and they all play wonderfully in Keynote, but they won't export! I first tried it with MP3's then AAC's...same story. I didn't want to use AIFF's because of the size.
    Any ideas would be greatly appreciated. This is very frustrating! Oh, I have QT Pro so that's not the issue either.

    What format are the audio files? If you created them in Quicktime as .mov files and placed each .mov file on a keynote slide they will not be recognized on export. The sound files will be fine if you export your keynote as a .mov.
    To export as a Flash swf, change all the files to .aiff files. You can do this for each audio file by opening the audio file in QT and converting/exporting it as an .aiff file. Then place the new .aiff file on each slide but make sure to delete the original .mov audio or you'll have two sounds playing in the original keynote.

  • Audio click on exported video

    I've imported a track from the music library onto the timeline. There does not appear to be any sound problems on the track. However on the exported movie DVD there is a 'clicking' sound heard with the normal audio.
    I can't see any way of rendering the audio seperately in FCPx. Is it beacise of a problem importing .mp3? files. How do I resolve this, any help most appreciated.
