AVCHD audio glitch/drop on spanned clips - CS4

Hello all,
I was wondering if anyone else is experiencing this issue.  We have an Sony NX5U Camera, and when we shoot long format, the camera breaks the AVCHD clips into 2gb sections. (Spanned clips).
When we bring them into Premiere CS4 they play just fine - except at the point where the 1st clip joins up to the 2nd clip, and so forth.  There is a small audio drop out, about 1/2 second in length.  It is not on the file itself, (plays just fine in camera, and in FCP on Mac), this only occurs in CS4. It seems to be the way CS4 is reading the file.
We have tried multiple workarounds, creating proxy files in AME, rendering out just the audio, etc, but it seems no matter what we try we always loose 1/2 second of just the audio on spanned clips.  This is not just a render/playback issue. Even if we run the original MTS files through AME and export avis of them, they still produce the glitch when in premiere - thus the problem is the way CS4 AME and PP is reading the AVCHD MTS files.
Anyone know if there is a work around for this?
We are running CS4 4.2.1 with a pretty fast system.  Quad 3.2ghz, 4gb ram, win xp 32bit.   Again, playback is not an issue, its only when the 1st part of a spanned clip meets the 2nd part of a spanned clip.
Lastly, based off someones post on youtube regarding this issue, they recommened a MTS merger program - however the merged files take forever and a day to load. Didnt really work.
Thanks very much for any help!!

Hi Eric,
Thanks for the reply, but unfortunately this doesnt work - that was actually the first thing we tried.
This is a known problem in Premiere, perhaps its actually more of an issue with AVCHD than Premiere itself, but Im looking to see if anyone has a workflow to correct this issue.
Thanks!

  • FS700 AVCHD Audio Glitch

    Hi All,
    We are working with two iMac's via a Lacie 5 Big Network Harddrive. We are using the most up to date version of Premiere CC 2014.
    We swap projects from machine to machine on a daily basis depending on what editor is assigned to the project.
    We have found a few times that when we are editing with FS700 everything seems fine on import then when we switch machines or open a project up a few days later, audio glitches appear and cannot be fixed! The only way I can describe it, is that the audio loops a 1-2 second chunk for the entire clip. The waveform shows this too. We have tried to take the files offline then reconnect but that didn't work, even tried re-importing but the same issue occurs.
    I have read that a few people have also had this issue with AVCHD footage. I did read that Adobe fixed this problem but it is still happening on our systems.
    Does anyone know a fix or can Adobe confirm if the next update will fix this?
    Thanks

    Hi John,
    Were the media files ingested correctly? Was the entire contents of the SD card copied to the hard drive and then ingested via the Media Browser? If you did not ingest in this manner, you can have problems with audio.

  • Audio glitches/drop outs with Guitarport/Gearbox

    I'm using Guitarport with the Gearbox software. My speakers are plugged into the headphone jack of GP, and I'm using GP/Gearbox as my default audio. The problem is that whenever I do this, there are audio problems, such as glitches/skips/drop outs. However, when I plug the speakers straight into the computer's headphone jack, there are no problems. So is Gearbox using up too much PCU or whatever? There is supposedly a "Processor Performance" setting for the OSX, but it is not there. I'm using a MacBook pro.

    Make shure you sample rates and buffer sizes match. Check AMS or Sound in pref.> after application launch, sometimes it will flip automatically. Master then Slave i think > you might need more usb power

  • Adding blur and drop shadows to clip cs4 Mac

    Hi,
    A while ago I saw a vid where they showed how to (to the best of my recollection) take a car out of a clip recolor the background and then replace the car w added effects, I believe it's in Ppr.
    Can anyone direct me to this vid or, one that can show me how to figure out this type of process.
    Tks

    I'm going to give it a try, take it easy on the chomping as what I'm finding is that cs5 is sooooo ssllooowww. I tried to open and convert to frames in p/s
    matter of fact there ended up being about 400 of them! Man, I could've thrown a burger on the pit and eaten it in the time 5 took whereas 4 wouln't
    have given me time to flatten the burger let alone thrown it on the pit. Sorry to say mate I have found most of it slow and did not take as much
    advantage of it as I would have liked to. But I will give this rotobrush a run around the block and see what I can get out of it.
    By the way I'm sure they will iron out the problems with speed  they always do, it's just like buying a new mac, It takes time to work out the intial ups
    and downs but, when one does it flies.
    All the best

  • Audio Glitch in Adobe Premiere Pro CS5 Timeline (not a clip problem - it's the timeline space)

    I have an audio glitch that appears to be tied to a space in my timeline and not to a certain audio clip.  If I drag or move the audio clip further up or down the timeline it plays fine.  If I move a different audio file into this area, the audio drops out in the same area, even with volumes set where they need to be.  There are absolutely no keyframes set in this area and I want to be clear about that.   However, this issue did come up only the software froze on me as I was loading my project.  I believe my best bet is to delete delete my media cach and media cache files so that clips are reconformed... unless someone has additional input or has experienced similar issue with the sound.
    As a note, I also reinstalled Quicktime.  I am working with AVI files/aac auio codec.

    No. You will not find any Master Track Keyframes. These will be on the Audio Track, and will be attached to the Track, regardless of what Clip you have there. Here is a look at Track Keyframes, not to be confused with Clip Keyframes from PrPro 2.0:
    Hope that this helps and good luck,

  • CS6.0.2 Update No Fix For AVCHD Spanned Clips - Workarounds?

    While I try to avoid Spanned Clips as much as possible due to a history with Premiere importing them, for event coverage we still get them and I just can't figure out how to make them work in Premeire CS6 on OS X. I see lots of posts about this and would like to know if there is a fix that does not require purchasing another product (like MTS Merge $35).
    We are using AVCHD footage from Pansonic cameras and if it spanned, the sound will be missing for much or all or the clip.
    I have tried using the Media Browser to import the entire AVCHD folder.
    I have tried using Panasonics AVCHD Viewer application to import the footage (switches wrapper to .mt2s instead of .mts).
    I have tried transcoding to new codec (Quicktime and VLC will play the MTS file correctly but output loses audio sync).
    Ugh, this is terrible. Has anyone else found a workaround?

    Unfortunately this is not a spanned clip problem with Adobe or Panasonic. This issue does come up from time to time.
    Be sure when you pull the card from your camcorder, you LOCK IT immediately. Then it becomes impossible to change anything on the card purposely or inadvertantly (and as you are aware, changing anything - structure, file names, ANYTHING - on the card will blow the whole operation, so locking it is perfect). Also, sometimes Mac users have problems when they fail to lock their cards, because Mac OS immediately starts writing files to the card if it's not locked.
    When you're using the Media Browser in PPro, be certain that you are viewing the clips in AVCHD mode (there's a dropdown option for this right there in the Media Browser). If you're importing individual clips from a single continuous recording, you're NOT in AVCHD mode, and this will always cause the problem you are describing.
    I don't mean to lay this out as "you're doing it wrong" but unfortunately this is all very well documented at this point, and whenever there is a problem with spanned clips, it is 100% of the time due to a user that renamed something, moved files, or otherwise didn't follow the complete rules of AVCHD management. I don't normally use a term like 100% (tend to prefer 99.9%) but I say 100% because it is absolute in this case.

  • IMovie '08 on my mac mini '07 drops audio levels at ends of clips no matter what I do to stop it!

    In some but not all of the clips in my project, the audio level drops down for the last half second or so. I have tried every effing audio setting including setting fade to 0 seconds manual, normalizing, not normalizing, and every combination I can think of, but it's just not working.
    When I google this problem, I find a few unanswered questions going back to imovie 2 in 2003, but no solutions short of remove the auto fade and set manual to zero, which again, isn't working for me. It really ***** to spend a whole afternoon working on a project to have it corrupted beyond repair. Anybody have any ideas of how to fix this, short of getting adobe premiere and/or a newer mac or even, a windows machine?

    Ok, here's another set of step-by-step instructions for configuring an extended network. Please give them a try to be sure you didn't miss anything.
    Dynamic WDS - Extending a Wireless Network Setup
    If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.
    Open AirPort Utility, and then, select the base station that will connect to the Internet.
    Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
    Click AirPort in the toolbar, and then, click Wireless.
    Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then, select the “Allow this network to be extended” checkbox.
    Next, select the base station that will extend this network, and then, choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
    Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then, choose the network you want to extend from the Network Name pop-up menu.
    Enter the base station network and base station password if necessary.
    Click Update to update the base station with new network settings.

  • AVCHD audio dropout at 15 seconds, but clip is fine in other software

    AVCHD audio dropout at 15 seconds, but same clip is fine in other edit software--  I'm generating proxy files for a client from a Panasonic AF-100 shoot.  All but one clip work fine.  The problem clip plays back only the first 15 seconds (exactly) of audio.  No audio appears at all on the waveform.  This problem is in both the source and record monitors, and across projects.  Media Composer and FCP both imported the file with no problems.  Is there a known issue with AVCHD and CS6?

  • Premiere Pro CC 2014.2 and AVCHD audio bug

    The AVCHD audio is mangled by Premiere. Details below.
    I recorded a 2 act play and I'm editing it in Premiere. Each act is about 1 hour so the camera recorded spanning MTS files.
    Act 1 imported perfectly. No problem.
    When importing act 2, I noticed some audio glitches and the audio quickly lost sync. After further investigation, I found that:
    - The AVCHD file plays perfectly fine in Quicktime player
    - The audio track in Premiere is exactly half the length of the video
    - When listening closely, it sounds like it plays 1 second, skips 1 second, plays 1 second, etc. Which is consistent with losing sync gradually and finishing the audio twice as fast as the video.
    It seems related to the problem in this thread. I'm at a loss as to what to try next.

    After posting the initial thread, I reinstalled Premiere Pro CC (7.0), created a new project, imported the AVCHD files and the audio was synched.
    I then opened the file in CC 2014 and the audio was still synched.
    So it appears to be a bug in AVCHD conforming in 2014 only. While not a fix, I hope this workaround will help others.

  • AVCHD audio tracks

    I set my AVCHD camcorder to record stereo audio.
    When I drop a scene onto the timeline, 3 audio tracks appear.
    The top audio track is stereo and enabled. 
    In this respect it is like when I drop a clip from my DV AVI camcorder.
    However there are 2 more tracks. I thought they may be Left & Right, but they are both stereo.
    Are they the other 5.1 tracks, even though I only select stereo on the camcorder?
    The camcorder is a Panasonic TM900.
    Thanks,
    Erik

    Harm,
    I thought that the number of tracks in the preset meant the number of available tracks appearing on the timeline.
    I set the number to 1 - because I had recorded stereo - one (plus master) appeared.
    But when I dropped an AVCHD clip, three stereo tracks appeared. If i drop an AVI clip, only one appears.
    Does an AVCHD always contain 6 tracks?   ie, set up for 5.1 irrespective of whether you select stereo on the camcorder?

  • Audio stereo signal split into 3 or 4 stereo audio signals (in one single clip)?

    Hi,
    facing massice transcoding issues when exporting a project I had to analyse the involved video/audioclips...
    and found out that for some of the video clips the audio signals have been split into even 3 or 4 complementary stereo channels.
    Note: Each channel contains just a part of the original signal. This is obviously due to cutting action ...
    What can I do? I have no clue!
    My question:
    How to get one single stereo audio signal (2 channels) out of this mess?
    Thanx big time,
    Oliver

    Assuming we're talking about shorter takes and not a longer, spanned clip, I don't think what you want can be done in PP.  Nesting will always bring the audio over as one track.
    You may have to skim the clip sequence in the Program Monitor and copy/paste the portions you want to use into a second sequence for output.  This will preserve the audio.

  • Another spanned clips bug?

    I've read that Adobe recently fixed a spanned clips bug. Well here's another one (at least on my system):
    I have several spanned clips recorded with my Sony FS700 (MTS-files in AVCHD-container) and my Panasonic P2-camera (P2 MXF-files). When using Adobe Media Encoder (AME) to convert to ProRes, the spanned clips are joined right, but AME encodes the same material several times. The result is several copies of the exact same encoded material written to disk.
    Here's how it works:
    In one case, my camera had split my recording into 4 individual files. I expected AME to a) either join them and output one long file or b) not to join them and just output 4 individual ProRes files. Instead I ended up with 4 joined identical 32 GB files on disk. I did it again and noticed that AME actually encoded the same material 4 times in a row. What a waste of time and space …
    When using Sony MTS-files, AME creates different filenames for each clip (0001.mov, 0002.mov, 0003.mov. When using Panasonic MXF-files, AME put _1, _2, _3, etc. at the end of the filenames.
    In my opinion, AME should have a tick box where you can chose "join spanned files" or not. If it had such a box, it would chose to leave it off most of the time. That way it would be much easier to check if AME has converted all the files or not. It would be 32 files in = 32 files out, not 32 files in = 2 spanned files + x small files out … Nowadays, I have to doublecheck everything before formatting my cards.
    I'm using Adobe Media Encoder v. 7.2.0.43 (64-bit) and OSX Mavericks 10.9.1 on a late 2013 Macbook Pro 15-inch Retina 2,3 GHz i7 16GB RAM 512 SSD.

    Jim Simon, let me explain:
    1. When I drag MTS-clips into AME, the software generates several copies of the same spanned clip during conversion. (They pop up in the queue while AME is converting).
    2. When I drag MXF-clips into AME, the software generates several copies of the same spanned clip before conversion. In the screenshot, which was taken after conversion, you'll see that the file numbers begin with 0018, 0019, 0019, 0019, 0019, and then jump to 0023, 0023. Well, what I dragged in was 0018, 0019, 0020, 0021, 0022, 0023, 0024 etc. So I believe AME skips filenames that are elements in a spanned clip, and then multiplies the the process all by itself. But, yes, I could manually examine the queue and erase identical clips after I drag files in. But that is just not a good way of working …
    So, AME behaves differently with spanned MXF and MTS-files, but none of them are handled right.

  • Audio volume drops in FLV file after inserting into Captivate 4

    The audio volume drops almost 50% in FLV files inserted into Captivate 4.  Is there a solution for this problem?
    Thank you.

    Hi Sony,
    That was the first thing I ever tried when I discovered the default setting for FLV and slide video (variables and advanced actions are my favorites, as you know perhaps). Perhaps I missed something, and did not try in CP 5.5 or after the latest patch on CP5.0, but this system variable seemed only to have effect on the normal audio clips, not on audio for video?

  • AVCHD 1080p mit 50fps in Premiere Pro CS4 importieren

    Mein Camcorder liefert Dateien im Format AVCHD 1920x1080 mit 50 fps. Welche Einstellung muß ich in Premiere Pro CS4 vornehmen, damit ich diese Dateien bearbeiten und an Encore CS4 weiterleiten kann? Mein Ziel ist es eine bluray-disc in bester Qualität zu brennen.

    Danke für die Info. Habe meine Files in eine Sequenz mit Einstellung AVCHD 720p 50 fps importiert, dabei musste ich die Clips auf Framegröße skalieren. Danach war eine Ausgabe in Encore mit MPEG-2 und 1280x720 und Framerate 50 möglich. Bei meinen vielen Versuchen hat das die beste Qualität auf der bluray ergeben.

  • Audio Gain and Normalize - different in CS4 to CS3 - problem

    Before in CS3, if an audio clip was peaking into the red I'd just right click, select Audio Gain, then click Normalize and then OK - the audio would be normalized and no more peaking into the red. Now in CS4, the right click Audio Gain brings up 4 options. Say if the Peak Amplitude is -0.5dB, which of the 4 options do I select to normalize, and what dB number would I put in to stop peaking into the red? I've tried lots of things but the sound meter still shows peaking! This used to be super easy in CS3—what is method now for CS4?
    Any help please!!

    One thing to consider is that if your Audio has already been recorded and you're peaking, you can Normalize, or otherwise process your Audio, but you're already clipping signals. It takes a lot to try and restore that "clipped" signal and you can only come close. The -3db/-5db is great for when the recording is being done. If the levels were exceeded at the time of the recording, and that is all that you have, then most processes in post will only be working with the clipped signal.
    I usually shoot for -5db in the recording process and then maintain something in the -5db to -3db range when editing. This way, I am working with the full, un-clipped signal.
    Also remember that with most "normalization" processes, you just establish the max for that signal, clipped or not, and then bring up the quieter passages to relate to that. Is that what you really want to do? Better to record the Audio at the proper level, with no clipping to begin with.
    Good luck,
    Hunt
