Audio visible in timeline but drops out on playback halfway through clip

I've been using Premiere Pro for a few years now and this has never happened to me before.
I am in the middle of putting together some long clips - anywhere from 3 minutes to 20 minutes long - and all of them worked fine except for the one shown here.
At the current edit point the audio drops out on playback. As you can see from the timeline, the audio is there. The rest of the clip prior to this point plays fine. Every other clip in the project plays fine. This particular clip loses its audio after 10:18 despite the fact that audio levels can quite clearly be seen in the timeline.
I am at a total loss. I've tried rendering, closing/reopening, restarting, re-importing ... everything. I hope someone else has a better idea.

Had the same problem and as solution used nero movie maker, where with sound was everything allright, and exported only sound. When exported a WMA format - premiere showed the same bug again, but when exported WAV format - premiere worked normally. It's not a 100% solution, becouse I had a 5.1 sound, that was converted into stereo sound.
Similary did with a videoclip, that could not import in premiere (premiere crashed) - via nero movie maker made ir from .mts to wmv with a little loss of quality.
Camera: Panasonic TM700
Software: Premiere CS4
File type: .MTS
It is a shame to such a expensive software
Update: these days I faced with this strange bug again and I had an idea to test whether this sound loss affects also exported media. I made a 20 seconds experimental clip and noticed, that there with sound is everything allright. So this sound loss is only in editing process and does not affect exported material.

  • Audio out of sync halfway through video.

    I recorded some game play (skyrim) and did a voice over with Mirillis Action! The video and the voice over are in separate tracks.
    The weird part is that the video and voice over match up at the start but once it gets about halfway through you can start noticing that the audio comes out of sync with the video and it only gets worse from there.
    I record in 1080p at 30fps using AMD App acceleration. The video is in MP4 and audio is in WAV (using this over MP4 Audio because WMP refuses to play MP4 Audio files)
    If the beginning is synced then the ending is off and if the ending is synced the beginning is off.
    Any tips on why this might be happening or how to fix it?
    P.S. I had to record them in separate tracks because otherwise when I talked over the game, it would have some strange background noise.
    If you need any further information please let me know.

    If you screen capture program records to a Variable FRAME Rate you will need to convert it to edit in PPro

  • Audio dropping out during playback in timeline

    Hey everyone,
    I've dug through these forums and unless I just completely overlooked it I have not found a solution to this issue. I've listed my setup below and then have stated the issue I'm experiencing.
    27-inch, Mid 2011 iMac
    3.4 GHz Intel Core i7
    16GB 1333 MHz DDR3
    AMD Radeon HD 6970 1024MB
    Running Mac OS X Lion 10.7.5 (11G63)
    Currently working off of a portable 1TB G-Technology G-DRIVE via FW800.
    Working in Premiere Pro CS6 Version 6.0.2
    Editing in a sequence with settings:
    1920 x 1080 23.976fps (also tried in a 29.97fps timeline with same issue)
    Working with footage that is 23.98fps
    Working with a combination of ProRes 422 (LT) and native H.264 Quicktime files strait from a 5D Mark 3.
    The issue I'm having is during playback the audio will competely drop out. The video will continue playing on just fine but the audio drops completely out. All audio levels drop as well in the audio mixer meters so it truly is losing all communication with my audio layers in the timeline.
    I read in other forums to go into Finder and delete out the .caf files, re open Premiere Pro, wait for them to be recreated then carry on. I tried this approach with no luck. Deleting the .caf did not change anything. Audio is still dropping out as I try to play through my timeline. The only way to get the audio back is to pause then press play again. I have 5 total channels of audio with only 2 of those channel active.
    Any ideas on what is happening would be greatly appreciated. This is incredibly frustrating have to export out a video just to be able to watch it through.

    Having this annoying problem also.  Using the Space Bar to play timeline it takes pressing and holding to a count of three or trying press play three time in a row using the space bar to get ungarbled audio, or any audio at all in a normal uncomplicated sequence on the timeline.
    Really annoying.  Audio used to be so simple and untaxing to a sequence.

  • No Audio In FCPX Timeline, But It's In The Clip Window

    I grabbed some video with my iPhone and imported it into FCPX. I'm ready to start editing, so I drag the clip into the timeline -- but there's no audio. Previewing the clip in the Clip window/area pays the audio just fine -- but I get nothing in the Timeline. I see the waveform, I see the meter moving like it should -- but no audio.
    What am I doing wrong?

    Luis!  Hi, it's me again...the person with the conversion issues?  Anyway, that has been solved thankfully.  My new problem is what has been mentioned in this thread.  Audio in Clip Viewer but not when dropped in the Timeline.  I attempted the fixes suggested in this thread but I'm using FCP Version 4.0.1 (old, I know) and the steps given aren't the same.  The first part of my project has audio in the Timeline...I'm guessing I clicked or unchecked something...I've looked everywhere and can't figure it out.  Even pulled out the manual!  Let me know if you have any suggestions and thank you in advance!
    I have not used older versions in a while, but I guess you may have disconnected the little "a1" from the big "A1" as seen in the image below. Drag to reconnect them. If this is not it, then I can only suggest you ask this in the Final Cut Studio forum (or Final Cut Express forum - I imagine that is what you are using).

  • Audio Drops Out at End of Imported Clips

    Hi, Guys,
    I have read everything and tried everything, but I can't find a solution to something which seems like it should be obvious:
    I am in the process of uploading some TV programs to YouTube. I am using iMovie '11 to cut them into chunks of less than 15 minutes each. When I import the material into iMovie from a file, iMovie automatically breaks the source material into ~5 minute clips. For some reason, the sound for the last half-second or so at the end of each clip is automatically muted by the import process. Needless to say when I cut the clips back together in an attempt to recreate the video stream as it originally was, there is a half-second of audio drop-out marking the spot where the clips are welded together.
    How can I get this to stop???
    I notice that the advertising makes a big point of 'iMovie HD' allowing the user to adjust the length of the clips that it cuts source material into during import. Please tell me this is not a work-around for this problem 10 years after-the-fact!
    Thank you.

    I used to have a saying which I applied to John Cage's compositions:
    "He's got nothing to say, and he's saying it. And that's BS."
    Faceless capricious corporate censorship is good HOW?
    As regards iMovie '11 muting a short bit of audio from the ends of clips, it turns out to be the beginnings of the clips:
    My prior post uncovered a very different problem in my process. (At the time, a virtually non-existent process!)
    Now I have learned my up the learning curve to the point where I am beginning to actually use some of the functionality in iMovie '11. Unfortunately my original observation of "a bit of sound" (50 to 100 milliseconds) disappearing between clips is still a problem. Here are 3 minimalist examples in the form of short test vids: {Just click "Play all". Titles projected over the vid list what you are hearing. The "about box" (YouTube "Description:" field) contains even more detail.}
    http://www.youtube.com/viewplaylist?p=7E219251FC3C5FEC
    I can now characterize this problem in more detail than I could previously:
    The first 50 - 100 milliseconds of sound are squelched in the beginning of a clip when it is uploaded to YouTube from iMovie. This is NOT a YouTube transcoder issue. Reloading multiple copies of the same clip into iMovie yield the same result there: Dead sound between clips.
    This demonstrates that iMovie chops the first ~50 milliseconds of audio off of the beginning of a vid when it "shares" (exports) it. Apparently the missing audio in some way becomes an "attribute"of the clip (like a crossfade transition that you can't remove from the beginning!), because attempts to trim the squelched audio off of the beginning of the clip meet with failure; the "bad leading edge" stays with the clip, even after the apparently offending segment has intentionally been discarded.
    I checked the audio gaps with Audition, and, while I was guessing 50 - 100 ms, it turns out to be exactly 52 milliseconds of audio is squelched at the beginning of a clip. (I tried to display the image of the spectral & time-domain response here, but I can't figure out how to upload TIFFs into this forum.)
    I am sure this must be the result of some simple default setting in iMovie which automatically adds a "style" or something to my vid clips upon export, but I have tried everything I can find, and, if it is, I haven't managed to reliably turn if off yet.
    N.B. if I remain inside an iMovie editing session, and paste pieces together into clips without exporting the clip, or interrupting the session (as I did to produce the test vids), everything is fine. But as soon as I save a clip, the first 52 ms of audio seems to irrecoverably disappear. That continues to hold true no matter which frame in the clip subsequently becomes the new beginning.
    Please forgive my iMovie newbie ignorance, but: How do I get it to STOP???
    Thank you.

  • Audio locked at playhead, but goes out of sync if video is cropped

    Hi,
    Using iMovie HD 6, I have the audio locked at playhead, but if I crop part of the video (beginning or ending), the audio goes out of sync.
    Here's what I've done:
    1) Extracted audio from video
    2) Silenced this audio
    3) Imported audio from audio recorder (Edirol R-09HR)
    4) Synced the imported audio
    *5) Attempted to crop part of the video footage in the timeline... goes out of sync
    How do I keep the audio in sync when cropping video?
    Thanks!

    Hi JohnDoe2009 - firstly, extracting the audio is not necessary in your case. Simply mute the video's audio, by reducing its level to zero - that is what actually happens when you extract the audio, after all.
    It is my experience also, that locking audio clips to particular video clips is not fail-safe if further cropping is done afterwards, especially if that cropping is fairly substantial. Where possible, do the syncing after all crop-editing has been completed.
    As a last check I always review the syncing before finalising the movie.

  • Audio Is Randomly Cutting In And Out In Playback

    I have encountered this problem on all recent Premiere projects I've worked on with a variety of audio types. My audio is cutting in and out in a seemlingly random way while the video keeps running fine. Sometimes the audio will play fine for 15 seconds then stop, sometimes it stops and starts after about 2 seconds. I have tried adjusting all of my preferences, settings, audio types, and even video types but the problem always comes back. Spoke to a friend who's new to Premiere and he's having the same problem. Considering moving back to FCP despite the weak interface.
    Currently I am editing Canon 5d Mkii footage at 1080p, 29.97 fps. I am using none of the audio attached to the video clips - only editing to a separate m4a music track. My audio is at 44100 Hz. I am playing back video at 1/4 quality. I am running a fully updated Mac Powerbook with a 2.6GHz Intel Core i5 and 8gb of RAM.
    Please help, almostly completely unable to edit. Thanks.

    I am still having the same issue in Premiere CC 8.0.1 (21)
    Exact same issue as the original poster on this thread, as well as the original poster on this other thread:
    Premiere Pro CC Audio Cuts Out
    So this audio issue persists from version 7 now in version 8.0.1!
    For me, audio is cutting in and out randomly and never in the same place. If I have multiple audio tracks on the timeline, then one or more tracks might drop-out at the same time. Sometimes all tracks drop out at the same time. It seems completely random.
    I am editing with a combination of P2 footage and DNxHD 290 footage. (I originally had some AVCHD footage, but then I transcoded all of it to DNxHD 290 -- but this did not improve the audio issue at all.)
    Two of my audio tracks contain the native camera audio (stereo); 1 track has the music bed (stereo .wav files) and 1 track has sound effects (stereo .wav files)
    In one of my projects, I had a very strong reverb effect applied to the track (not to the clip). When the audio dropped out, I could still hear the tail of the reverb. This leads me to conclude that it's not the entire audio track that is muting -- it's definitely the source audio clip that's dropping out. The reverb tail continued after the audio dropped out.
    Playing the same part of the timeline again produces randomly different results -- audio might drop out on a different track, or at a different time, or not drop out at all.
    This bug is making it nearly impossible to edit! I have filed a bug report at http://www.adobe.com/go/wish_fr
    During timeline playback, my CPU utilization never goes above 15% and at least 12 GB of RAM is staying free, so I am pretty confident these drop-outs are NOT caused by lack of computer resources. Also, my hard drives seem to be fast enough to play back 4 streams of HD simultaneously, but I am getting these audio drop-outs when playing back 1 stream of HD plus 4 channels of audio. Therefore, I don't believe this can be a hard drive bandwidth issue.

    Windows 7 64 bit, SP1
    RAM: 24 GB

  • Right channel drops out on playback

    I'm noticing that when switching between effects or just replaying a track I've recorded, the track initially has a right channel (which i can hear), but a second later, just drops out. Still in experimental stage in recording, but wondering if anyone has a reason for that happening.
    I'm using an M-Audio Fast Track Pro device to get my input with acoustic guitar.

    SteveG,
    Good suggestions. I tried those too. Made not difference. However, this did. I poked around here and found a solution.
    _durin_  had a great remedy.  See this post: Playback stops when in multi-track
    Also, now that I have made these settings, things seem to play back quicker and renders are faster.  I still have a lot to learn.
    Thanks so much!

  • Audio Glitches on Timeline, but not when played in QT?

    I had a client send me his project on a harddrive.
    They exported a .mov file from FCP and it has no audio glitches when played with Quicktime.
    But if i drag that file to a timeline and watch it through my DSR-25 to a NTSC monitor, it has audio glitches in certain spots.
    Always at that spot though and if i watch the file in Quicktime, it plays fine.
    All audio was exported originally out of FCP using Quicktime Movie with 48khz, 16 bit stereo so nothing needed to be rendered.
    Seems like it has something to do with it going over via firewire through my DSR-25.
    Has anyone else had this problem.
    I can't make a Master DVCam tape for this master because of these audio glitches.
    Thanks for any help,
    Brian

    I read a post about a user having this same sort of issue.
    He said when he turns off his video layer, in my case just V1, the audio played fine.
    Same with mine.
    So it seems to be an issue with the video track playing with the audio track.
    If i export it and bring it back in, will it just create that same audio glitch?
    Guess i will have to try.
    Anyone have this issue or similiar?
    Thanks,
    Brian

  • Audio Pop/Clicks, then completely drops out

    This just started happening to me completely throws a wrench in my workflow.
    I'm watching lectures using VLC. I pause the video, take some notes, then click play and hear a pop or a click. then no audio. this renders my whole soundcard useless ie no audio output from any application. My current fix is to restart my machine, but considering I have a few other applications open to take notes, it really is a hindrance.
    any suggestions? or do i have to take this thing to my local genius bar?

    Update: When detaching the audio, this problem goes away.  However, the audio fade-ins from transitions, etc. go away.  Is there any way to solve this problem without detaching?

  • Help!  Trying to export 1080p Timeline, But get 'glitches' on playback

    I am Trying to export HD file that will play without 'glitches'
    The timeline plays beautifully--no problems.
    I use Adobe Exporter and I have tried MPEG2 Adobe profiles, standard and my own custom presets= glitches are still there, just at different places.
    So I figure I would try to render the entire timeline, still glitches.  Audio wise: Sound like dv digital dropouts-- Videowise: can't see other than the the frame stuters for a frame or two then starts again--but it just seems like no matter what I try, I just get different spots of the glitches
    Anybody have experience fixing such problem?
    My system: AMD Phenom II X6 Windows 7 Pro and 8GB Ram, CS5 with the latest update for the GTX 285, which I am using.
    If you have any advice, please respond.  I have a tight deadline.
    Thank you!

    >glitches are still there, just at different places
    That usually means there is some kind of software running in the background that "wakes up" once in awhile to check to see if there is anything it needs to do... and every time it wakes up and STEALS the computer's attention, that causes a Premiere stumble

  • Audio sputters and then completely cuts out during playback

    Hello, everyone.  I've been editing in iMovie for years, and have never come across this problem until today.
    When playing back a clip that I've inserted into my project, the audio sputters on and off for about 10 seconds, and then cuts out completely.  If I stop playing, and then start again, the audio comes back, but in about 10 seconds, sputters and cuts out once again.  When I play back the original clip that I imported, this does not happen.  It is only when it is actually in my project.  The audio waves shown below the video are all intact as well. 
    I've already tried restarting the computer and deleting the iMovie preference file to see if that would make a difference, but it has not.  Any ideas as to what this could be, or even better yet, how to fix it?
    Thanks for your time.

  • How do I import an existing finalised imovie into a new project either in part or full. The movie I want to import is filed under "movies" but greyed out when I go through the procedure in imovie 11

    How do I import an existing finalised movie clip into  a new developing project ? I go through the imovie 11 procedure for importing and the list of clips (finalised and un-finalised) appears, but always "greyed out" which makes it impossible to create anything. I have tried placing it on the desk top and dragging but this doesn't work either.

    AppleMan  Thanks very much for the information, however I could't make it work. I followed your instructions to the letter, in fact I tried every which-way. I created a dedicated file into which I copied and pasted the project from "package contents"  but it was still greyed out when I went to retrieve it. I also found that the file size was reduced to only a few Kb.  Any further step-by-step instructions would be appreciated as I am obviously doing something wrong.  Babowa  It appears that in imovie everything has to be "finalised" before it can be used or shared elsewhere in the same way as a disk has to be to be played elsewhere. Funnily enough an MOV file I converted to Mp4 was not greyed out and I was able to import it.... an exercise I am not keen on because of resolution loss during conversion

  • HT3986 I'm having trouble partitioning my hard drive, I'm attempting to do this from the recovery drive because it's more convenient.  But when it gets about halfway through the process, there's an error message saying that it's having trouble unmounting

    Just realized that the title was limited anyways, I'm in the recovery drive on my macbook pro, trying to partition my macbook with another user (not windows, just another user) with only like 10GB.  It goes fine until it's about halfway done with the process, where it freaks out and tells me that it can't unmount the harddrive. Any suggestions?

    Hi, BDAqua,
    Nice to hear from you. You helped me with another recent question. Thank you.
    The external case is Other World Computing's Mercury Elite Pro with Oxford chip set. Drive is an Hitachi deskstar 500 Gigabyte disk (I'll dig around for exact specs, if needed).
    Weird thing is that the drive (partitioned into two disks, one boot, one for files) shows up in the Finder and in Disk Utility, but not in System Profiler. It's not visible at all there (not under Firewire, by which method it is connected, nor anywhere else). I can access its files, though, via Finder.
    Very strange.

  • Audio restarts at beginning halfway through clip

    I've captured three HDV tapes using PPro 3.2 and one tape has problem with audio: about half way through the tape, the audio goes back to the beginning. The audio plays as it should in WMP, so it's a Premiere Pro problem.
    I've deleted the media cache files and re-conformed the clip twice but the problem remains.
    How do I get the remainder of the audio?
    Thanks,
