Audio sync drift after "live" CD import and convert to 48/16

I shot DV footage on a PD150 cam. The band recorded a CD from sound board to replace the mic audio of the camera. I'm running Final Cut Pro 3, and I have already converted through Quicktime the CD tracks to aiff files running at 48 ( they were 44.1) and 16 bit. The DV cam Orignal audio was also recorded at 48/16. Now when I try to sync the Cd audio (48/16) to the video clips 1: the audio sync drifts off during the song, and though it started right, the whole sync is way off by end. 2: The audio file in the track bar is longer than the video clip in the track bar above. huh? Could it be data rate Audio 187kbps vs. Video 188kbps or should I try and slow/speed up the play rate of either vid or audio. Or is this an impossible meshing of media?

As Jim says, it's a function of how this was done. Next time you will know to look for ways to avoid the issue. But all is not lost.
I'll give you the skeleton and you can figure it out.
Find exact sync points near the beginning and end of the "video audio" and the "CD audio". Use drum beats you can be sure are the same. Identify them by ear and then by their waveforms, and put clip (not timeline) markers at those points.
Sync up the ones near the beginning exactly. Now go to the other two, find out how far apart they are, and write it down. How? I haven't got all day.
Calculate the time between the 2 markers in the video clips's audio, and between the markers in the CD audio.
Translate both of those numbers into frames.
Calculate the percentage by which the audio is longer CD audio / video audio = X%.
Go into Soundtrack Pro or audio app of your choice and make a version of the CD audio that is sped up by X%.
Bring that back to FCP and replace the version on the timeline with it.
If the markers didn't survive, find the sync points in the new CD version. Line up at the beginning. If the ones near the end now match, everything is done and you can call me "Helpful" and "Solved". If not you can be angry at me or read it again.
Good luck!

    Could it be the setting of a frame rate 60 in my camcorder that causes jerkiness when panning or what else?

  • After scanning my document and converting to Microsoft Word the size of characters are different

    After scanning my document and converting to Microsoft Word the size of characters are different and things like puntuation are distorted. How do I get the uniformity like the original?

    Of course what lands in the Word file will differ from the viewed picture/image of text created by the scanner.
    (The output of all scanners is always an image file. For an image of textual content the best output file format is TIFF.)
    So you scan the hardcopy of text.
    The scanner output image (picture) is brought into PDF.
    At this point the only PDF page content that you can export to Word is the image (nope, no "text" just the image).
    Consequently you use Acrobat's OCR feature to do OCR of the image of text.
    With a decent paper source, proper resolution and a black and white image you'll get acceptable accuracy of recognition of the pictures of the characters.
    (the Optical Character Recognition)
    Acrobat's Searchable Image and Searchable Image (Exact) provides output that used text rendering mode 3 (no fill, no stroke for the glyphs).
    So, invsible / hidden text.
    The third OCR method is ClearScan.
    You could play with each of the three to see what goes into a Word file.
    Might try export to RTF, DOC and DOCX as well.
    Anyway -- What is exported is the OCR output; Not the image of text.
    And, of course, the image of the text is not the imprint on the paper that was scanned.
    Each step to the way you have some deviation.
    Once you have the exported PDF content in a Word file you can use Word to cleanup as desired / needed.
    OR
    Prop up the hardcopy and transcribe to a Word file.
    Be well...

  • Playback pauses and audio sync issues with live video stream

    I'm seeing playback pauses about every three seconds and audio sync issues with our live demo stream when using the OSMF/Strobe player.  It happens on both our 2Mbps 720p stream and our 480p 750Kbps stream so it does not seem to be related to higher resolution/bandwidth streams.  It also happens if I point directly to a stream asset or if I point to a .f4v with both streams listed for dynamic so it does not seem to be related to dynamic streaming specifically.
    The same live streams play back very well without pauses or audio sync issues in the Akamai's dynamic player and even slightly better with JW 5.2.
    I have viewed the OSMF/Strobe playback on three different laptops of various age (3 months to 2 years) and two are Windows and one is Linux.  I have also tried the various buffering options on the Flash Media Player Setup and Strobe setup and it has not made a noticeable difference.
    To see the stream with the Akamai player, go to:  http://live.kulabyte.com
    To see the stream with the OSMF/Strobe player, go to:  http://live.kulabyte.com/osmf
    I do not have JW set up for public viewing yet, but the two above show the distinct difference.
    We are really hoping to start pointing our customers towards the OSMF player because of the support provided by the community and Adobe, but we have to get the quality of the playback to be acceptable first.
    If someone has ideas on debugging I can PM the actual video assets to you.
    Thanks,
    Tim

    Hi Tim,
    You need to add this setting:
    dynamicStreamBufferTime=8
    The actual value can be higher or lower. The best practice is to use a value that is twice the keyframe distance. Anyway, try different values and see which performs the best for your content.
    I know that the setup page does not contain this option and it is not documented in the UserGuide. We simply missed it. Sorry.
    Also note that the dynamic buffering algorithms are not being used for dynamic streaming content. I tried to explain this here:
    https://sourceforge.net/adobe/smp/wiki/Dynamic%20Buffering/
    Looking forward to your confirmation that this solved your issue.

  • Audio sync drift issues within Premiere Pro CS6, even with 48kHz project & source material?

    Evening guys and Merry Christmas to those who follow the tradition. I'm currently doing a few last minute tweaks to a live dance show that I recently shot. The show featured music that was recorded in camera (via additional mic) from the speaker setup within the theatre. This was always intended as a guide track as the original music would then be synced in the edit to give a cleaner sound to the audio during the dance sequences. I have the original CD that the music was played from on the night, however when the files are imported into Premiere Pro (or even Audition), they sync for the first 10 seconds or so and then gradually drift out of sync as the track goes on.
    My project is set to 48.000 audio, which was what the original footage was shot at, as well as the audio tracks being imported as 48.000 too. Now on paper there should not be any issues with this sync drift occuring right? I've even tried with 44.100 audio files and naturally they drift out of sync.
    At a loss here really as I'm not sure where i'm going wrong. Can anyone shed any light on this situation please?
    Thanks!

  • Audio sync drifting when recording

    Hi everyone,
    Has anyone experienced something like this?
    I'm recording a webcam.  A Polycom CX5000.  I have it set to record the encoded video and audio with a limit of 30 minutes (creates a new file).  While doing the encoding, I get no notification of any dropped frames, yet when I play back the resulting .FLV file, the audio drifts out of sync in the first file after about three minutes.  When the recording went over 30 minutes, FMLE started a second file and for some reason, the sync pops back on.  Is there a bug in FMLE or some setting I can do to avoid this?   I'm encoding on an i7 PC so I don't think it is a hardware issue.  For encoding I was using 15fps, 640x480 and audio at mp3 224.
    Thank you,
    Mark

    Hi,
    Thanks for your response.
    >1. Does the sync problem aggravates over time or does it remain constant from 3rd min to 30th min?
    It aggrevated over time.  You can't really notice it until around 3 minutes into the video.  I watched it again and it looks like it the sync fluctuates slightly. Goes out of sync, gets back in sync (or nearly) and then goes out again.   Listening on headphones I hear tiny, split second drops outs or glitches (related?).
    >2. Did you observe the sync problem in the live stream also?
    This time didn't even do a live stream.  Had similar issue two weeks ago that was live stream and file save.  Assumed the issue was due to network issues.
    >3. Can you reduce the file split time to let's say 5 min and reproduce the problem again?
    Will be trying this today or tomorrow.
    >4. Which audio device are you using? Is the audio and video device coming from the same device?
    It is from the same device (I think.)  I am remotely troubleshooting for someone so I'm not 100%.  It's a Polycom CX5000.  The first one we have.  We previously had a Microsoft Roundtable which is the same device.  The device names come up differently though so that's why I'm not positive.  The Video device is currently listed as Integrated Webcam (which must be correct as I'm getting the right picture).  The audio though lists "Microphone Array (IDT High Def..." something..    That might be the laptop's built in microphone?  If so, that might be the issue.
    >5. If you have a different audio-video devices, please try with them and come back with the result.
    Will let you know.
    I'm hoping it is #4 as that would be an easy fix. I would find it hard to believe Adobe released a product that couldn't keep audio and video in sync, right?

  • Audio sync drift - 44.1 to 48khz

    I have an audio track that was accidentally recorded at 44.1khz. I converted the audio to 48khz for import using Quicktime, but the sync drifts noticeably from the video after about 3 minutes. How do I correct this?

    Make sure the sequence audio setting is 48K, not 32K.
    If the audio was not recorded with video or with a TC based audio recorder, the likelyhood of drifting is quite high.
    Options -
    • You can cut and shift the audio in segments as the drift becomes noticeable.
    • You can use STP to RETIME the segment to something that stays in sync.
    I'm sure there are others ...
    Good luck.

  • Audio sync prob after capturing for 10 minutes or so

    I have an audio sync problem when I import into Final Cut Express. Everything is fine but lets say around 15 minutes or so there is a slight sync problem.
    What I have been doing is I import into IMovie because I have it setup to cut the clips after 10 minutes. This is great because I can let it run..and it automatically splits the clips up without any dropped frames at all. The problem is I then have to drag those clips..one by one into my external harddrive. That takes time and then I have to render the audio in Final Cut Express.
    I do like though that the clips are a little over 2gigs..which is good for transfering between drives and backing it up onto a DVD.
    Is there a way you can do what I do in iMovie...it automatically starts a new clip after ten minutes or whatever...this way I don't have to transfer and render.

    FCE does not break up clips on capture. You can capture in 10 minute chunks if you want.
    The audio sync problem can be caused by a number of things most common of which is using the wrong settings for your capture, where your settings audio sample rate doesn't match your media.

  • Audio sync problem after saving to QuickTime file

    Hi there, I'm relatively new to Adobe Premiere - I'm not quite knowledgeable enough about video editing to really use it to its full potential but needed something more flexible than Windows Movie Maker.  I haven't had any problems before editing smaller files, but am having tons of trouble with a 2.7 gig file.
    I'm trying to take a 2.7GB .MOV file recorded on a Kodak Zi6 and divide it into three roughly equal parts to use an email sharing service that has a maximum file size of 1GB (I know that there are sites that will allow 3GB files and I wish I could use them, or use an FTP server, but the person who needs the video needs it to be sent over his own company's file sharing system).  It was recorded on an 8GB SD card, that SD card was put into my computer, and I then transfered it over to Premiere Elements 8.
    I rendered the entire file first (it wouldn't even play until I did that) and after rendering, the audio and video were good and everything was synced up.  I then split the clip into three and saved each as a separate project.  Then I opened one up again and tried to save as a Quicktime file (that's what the person I'm sending it to requested).  All seemed to go well, and for the first minute or so of the 15 minute clip everything is great.  Then after that, the audio gets more and more out of sync as the video plays on.  I tried playing it on several different players, same thing.
    My computer (a Cyberpower PC) is running an Intel Core i7 CPU, 870 @ 2.93GHz 3.06 GHz; 8 GB of RAM; NVIDIA GeForce GTX 285; Windows 7 Home Premium.  I'm not sure where to get the rest of the information requested in the "How to best ask for help" post but if you can give me some guidance I'll find it.
    The presets are on the defaults because I wasn't aware of them until I came to this forum.  Happy to try the whole process again if someone can tell me what the presets should be changed to.
    I'm looking for a solution to this particular problem, but am also looking for some basic help about files.  The files that I used most often usually come from a Kodak Zi6 (.MOV) or a Flip Mino HD (MPEG4 I think; had to convert those to something else to use them in Premiere at all).  I have AVS Video Converter 6, so I can convert those files to pretty much anything.  I'm wondering what I should convert files to before trying to edit them in Premiere, and how best to save them.  I rarely use the files anywhere but online if that helps (this particular 2.7GB file being a big exception) at a maximum width of 550 pixels, so I don't think I need the quality to be all that great; it's more important to me to be able to work a bit quicker, without rendering that takes hours.
    I'd also love to take advantage someday of some of the more advanced features of Premiere, so I was wondering if anyone knows of any tutorials that will walk me through things in a linear way (as in, start from the beginning and teach me what I need to learn before moving on to something more complicated).
    Thanks so much for your help, and please speak slowly; I'm in over my head!

    Very well-done post, and welcome to the forum.
    First, many have issues with OOS (Out Of Sync) with QT files on Export/Share. This is not just with PrE, but PrPro also. Unfortunately, OOS is pretty easy to fix, when you encounter it on the Timeline, but almost impossible to fix when it creeps in during Export. As an aside, I fought some MPEG Audio from a client, that was perfect in the Timeline, but when Exported to MPEG-2 for DVD-Video, ALWAYS went OOS dynamically, and even adjusting for that on the Timeline (rather guessing how much OOS the other direction I needed,) just flat would not do it. Sync would be fine for awhile, and then suddenly start going out, before miraculously returning to sync with the next Clip. Never could get that one correct.
    In your MOV Export/Share, I am not certain which CODEC you chose. Was it H.264?
    Within the MOV "wrapper," did your recipient give you any options for the enclosed CODEC's, or is the wrapper and the file size the determining factors?
    Wish that I had more to offer directly, rather than questions.
    As for the tutorials, I strongly recommend Steve Grisetti's Learning Series, his Boot Camp and his many articles and general PrE tutorials on Muvipix. He also has several books, available there too.
    Good luck,

  • Audio sync drifting in rendered clips

    I'm using Premiere Pro CS5.5 on a PC running Windows 7, 2.80GHz Intel Core i7 CPU, 6GB RAM, 64-bit OS.
    I am working on an interview I shot with 2 Canon DSLRs, a 500D and a Rebel T3i, using audio captured with an M-Audio Microtrack II. The audio was edited down in Premiere then rendered out and handed over to a third party to be cleaned up in Pro Tools. The length of the edited interview is just short of 4 minutes.
    When I preview in my Premiere timeline the audio is synced but when I render out the clip the audio drifts so that it starts already out of sync by a frame or two and by the end it's clearly off by a lot. I'm not sure how to proceed since the audio looks more or less perfect in my timeline.
    I'm really hoping somebody has some suggestions as this project deadline is tomorrow, I'm supposed to be just making minor fixes at this point but suddenly I'm dealing with an issue that has totally broken nearly half my video.
    Thanks

    I'm definitely working with a mess of a project. Frame rates is actually one of the things I'm looking into and there are a number of discrepencies in settings between, raw footage (30fps from the 500d & 29.9 from the rebel), sequence (29.9fps) and export settings (59.9fps). Unfortunately in the overall project I'm working with video from a number of sources so I'm starting with a number of different frame rates (in other sequences I have captured video game footage that is 60fps too). I'm still going to try and match them up as best I can and hope it helps. I'm just worried that the destination for these rendered clips is a pre-existing After Effects project where all the comps are 59.9fps, if I try to change those and that causes problems I could be looking at a pretty huge set back right before my deadline.
    To add a little more detail, the problem seems to be getting progressively worse. In early renders there was no sign of an issue, then yesterday during a review we noticed it was slightly off so I thought i fixed it did a render last night and when I checked it this morning it was as I described in the first post. I have at least 3 or 4 early renders where the problem was either not there or so slight it's hard to notice. The really weird thing I've discovered, if I put the rendered clip back in premiere it syncs up, but if I play it in quicktime or use it in After Effects (the next step in my workflow) it doesn't. Guess that could still have to do with frame rates. We'll see.
    Thanks for the tip

  • Audio sync problem after scrubbing

    I'm trying to piece together some clips from a TV series called Legend of the Seeker. I'm using Premiere CS4 4.0.1, Vista Ultimate 64-bit.
    Placing the hour-long video in the Source Editor allows me to play the video fine from beginning to end, but if I start scrubbing through the file, the audio unsyncs itself immediately.
    Here's a screenshot of the video in GSpot:
    http://img14.imageshack.us/my.php?image=premieresync.jpg
    Setting IN and OUT points and then dragging a very small clip into the timeline has the same result.
    Any ideas would be very appreciated.

    You are actually pretty lucky to just have Audio sync problems, though I do not know why scrubbing would make any difference. With both Xvid and DivX one more often gets no Audio, or no Video.
    Agree 100% on the 3rd party conversion, prior to Import into PrPro.

  • Audio Sync Problem after transitions/filters applied to timeline in FCP

    I have Final Cut Pro 5.1.2 on a MAC Pro. I installed 2 Maxtor SATA II 200gig drives and created a striped RAID. I want to be clear about audio sync issues. I have my easy setup/properties....all those settings set to DV NTSC and I am monitoring out from my DV Deck via firewire, not the audio from the computer.
    After capturing the clip(s) I assemble them onto the timeline, add a few transitions or filters. The audio shifts off a lot. More everytime I add or do more with the clip. After rendering more, the audio shifts more. All scratch disks, rendered clips points to the Video Drive (striped RAID) I've setup. I'm not new to video editing but new to a MAC. Yes, I am a PC guy. I work with Premiere Pro 1.5. I am pleased so far making the switch, just need to fix this audio issue.
    All properties of the audio clip are correct, DV NTSC properties - 48K etc. This particular capture I made with 2 channel mono clips instead of a single DV stereo stream, simply because I have a split audio on the production tape and would like to take advantage of working with two seperate mono audio files. When I trim, I make sure the audio stays with the video but it appears that when I do trim, add a transition or filter, that's when the audio goes out of sync. No indication with a ("- #")on the icon. The clips which I captured are less than a minute long. Used for testing in these new learning stages.
    Questions:
    1. I created a striped RAID with the 2 Maxtor drives, I used MAC OS Extended (Journaled) with 256k Raid Block size. Is this correct?
    2. Would the audio captured in 2 channel mono affect the sync? (assuming you don't shift it manually on the timeline)
    3. What other MAC settings should I do to the system that will result in better preformances?
    4. What settings should I set in FCP for better performance results?
    MAC Pro   Mac OS X (10.4.8)   FCP Studio
    MAC Pro   Mac OS X (10.4.8)   FCP Studio
    MAC Pro   Mac OS X (10.4.8)   FCP Studio

    hi vcp
    welcome to the forum, glad you made the switch ... you won't be sorry (although you might be wondering at the moment!)
    1. nothing wring with that
    2. no
    3. just don't install 3rd party crap you don't need ... and don't install any anti-vrus software
    4. no special settings required
    what camera did you capture from? did you capture with FCP?
    cheers

  • Audio Sync Issue With FLME 3.1 and BMIP Card

    Hello Folks....First off..Happy Holidays to all.  Secondly...have Black Magic Intensity Pro Card (PCI-e) installed on i7, 3.33GHZ, 24 Gig Ram, Raid Controller  2x 600GIG Drives, Win7 64bit etc etc.
    Noticed today on a live show...we had an audio sync issue of half to full second.  This was being pushed via FLME 3.1 and audio was married to the BMIP audio inputs.
    Video input was Component and audio as analog.
    Any thoughts why this would happen?
    Bandwidth was more than acceptable (pushing 700kbps over a T1)
    Appreciate any insight.

  • IDVD audio sync problems after Lion upgrade

    Hi all,
    I posted this in the Lion discussion, but thought I might have a go here as well. I'm having problems with iDVD and audio sync as follows...
    I often download files from my Beyonwiz PVR, convert them to mpeg and DV files using MPEG Streamclip (with Quicktime MPEG playback component), then burn a disc with iDVD. Since upgrading to Lion, I notice that the audio in these files, and the burnt DVD in particular, can be slightly out-of-sync with the video. Although the effect is slight, I find it very unacceptable - its like trying to watch something that been badly dubbed. I find it to be a very jarring effect to watch voices and intonation out of sync with the picture.
    I'm not sure where the problem lies - is it Quicktime, MPEG Streamclip, and/or iDVD ? I never had this problem at all with Snow Leopard.
    Fox

    I've discovered that the problem appears to be the conversion of the mpeg file to the DV file. The video/audio goes slightly out of sync using MPEG Streamclip under Mac OS Lion. I never had any problem with Snow Leopard. I'll have to try different conversion methods and see what happens...
