AUDIO SLIPPING

Only when i am recording back to the DV deck does the audio slip after about 10 mins.
On the timeline the audio is in sync at all points.
the deck is a sony DSR45, i record in DVCAM mode.
The original audio and video is fed through this deck / firewire into my FCP system, LaCie FW -800 harddisk and the FW 400 from the deck connects to the computer FW400 port, the drive is connected to the iMac24 core2duo FW 800 port.
on capture i do not get audio sync error messages.

no, i exported the sequence with the 44.1 audio as is.
too many rubberband points to redo..
the export did a fine job of converting it.
also be aware that (previously) this sequence was used to export a quicktime movie ( not self contained ) that was compressed with Compressor, and burned to DVD with DVD studio pro 4 and there were no issues with audio slippage...
it was the day after when i laid it to tape that i had the slippage problems ... when i played the tape back today i was agast to see the end of the tape out of sync...
panic ensued.
seems this was the only occurance.

Nightmare with repaired AUDIO slipping out of sync ???

I have a concert shot on Sony camcorders 48Khz, and audio recorded to LOGIC PRO 44.1 Khz
My workflow is roughly this:
1. Log and Transfer footage into FCP.
2. Arrange the clips into a rough edit on the timeline.
3. Export the camera audio from FCP, as it is on the timeline. ( to 44.1 AIFF file)
4. Sync up the good audio in LOGIC PRO to the camera audio track.
5. Bounce the good audio in LOGIC PRO ( to Both 44.1 and 48 AIFF files).
6. Reimport the good audio track into Final Cut Pro, to replace the camera audio.
Logic is working in 44.1 as that what the multi-tracks were recorded in...
I tried importing the 44.1 and the 48 and both do the same
Theoretically, this should sync everything, lThe problem is the "good" audio from the Logic slowly slips out of sync with the camera audio.
BUT !!!!!....The WAVE FORMS SHOW THEN IN SYNC ????????
It just plays back a little faster....??? and goes out of sync
Another clue is that when I export the audio from the rough edit in the timeline (step 3), I can reimport the file that FCP produces and, when I put it on the timeline, it exhibits the same behavior: The exported audio track from FCP slowly slips out of sync with the EXACT SAME audio track on that's already on the timeline. How could it be slipping out of sync with itself after an export?
What a pain ??????

the Wave form is looking correct and all in sync
So, (to confirm) the audio waveform is syncing with the video?...very strange situation with the playback/sync.
Have you tried running Disk Utility/Repair Disk and/or trashing prefs? (I realize trashing preferences is a bit of a pain, but it does resolve many issues).
How full are the harddrives? What drive(s) is your media on and how are the drives connected?

Audio slip after being render

After Aiff audio is rendered in timeline the audio clip slips putting it out of sync with the edit. Audio came off a disc from itunes.
On a Mac Pro, 4 gig ram, 1.5 TB raid, running FCP 6.0.4.

Might try importing the audio as 48khz aiffs if they are not that...

Strange audio slipping problems??

I've been having problems with audio tracks slipping. It's only .mp3 music files... here's what happens: I'll lay down say 10 seconds of a music track in a timeline. A few minutes later I realize I need the music to run 3 seconds longer. I drag it out, and then render. This causes the music track to slip 3 or 4 seconds further into the song. The waveform display on the audio track looks exactly the same, but the song has slipped for some reason. It's been driving me nuts because if you spend some time keyframing volume and then have to extend the clip a second or two you basically have to start over. Anyone have any clue why this would happen???
Thanks!!

Rule # 1 (or 10, I forget): Do NOT use MP3 files in FCP. Instead, first convert them to AIF format at the sampling and bit rate that matches your FCP Sequence settings.
To adjust a song's duration, highlight the clip and hit Command j to bring up the speed adjustment window.

Sudden audio slip

Okay, I'm not sure if this topic has been covered, so I apologize in advance if it is redundant.
This has happened to me several times: In FCP 5.0.4 I make a document...add clips, add music, edit it, the whole works - then I save and quit. When I come back to it at a later date, I find that an audio track (sometimes the main music track) has gone out of sync. Out of sync in a way that it appears it has been slipped - the duration remains the same, but the music may start in the middle of the song and where it would end, it just adds the end of the song again to cover that remainder of time. What's going on here? If it were just a simple music track it would be fine, but when you edit the whole video to it, it's important to get that track back to EXACTLY the way you had it. Not to mention if you added any variable level adjustments to it throughout the file.
Help! What do I do? I'm not sure how to proceed until this question is answered...

I said I was "distressed"...I was calm, just confused as to what to do next.
Okay, I've done what you suggested and hopefully this won't happen again anytime soon.
I'm more curious as to what caused the problem in the first place? Is there something I can do to help the program avoid such mishaps in the future? I mean, luckily, I was at the beginning of the project - had I been at the end and had to recapture everything again THEN I would be less than calm! LOL
So this was more of a "brush your teeth and you'll avoid tooth decay" rather than "your teeth fell out - well, here's how to fix it..." but I do appreciate the assist all the same. Thanks!

Audio Slipping (Sync issues) steaming video.

Hey all,
I was wondering if this had happened to anyone else.
Since updating to Yosemite i've noticed a real problem when streaming video online through my web browser.
Regularly whilst watching a video there is a crackle on the audio track, then a second of the audio is repeated almost like an echo.
When this happens however the video caries on meaning the audio and video are out of sync.
This occurs on everything from Netflix, Youtube, DA Clips and other video sharing sites.
It occurs on Google Chrome, Safari and Firefox.
The only way to fix the problem and re-sync the audio is to reload the page with the video and begin again.
Unsure whether this is related or not but i've also noticed some slipping of audio when playing music in spotify. But obviously because it has nothing to sync up to you just hear the same word twice and it carries on, kinda like a scratch on an LP.
Would really appreciate any words of wisdom.
I'm currently running OS X Yosemite 10.10.1
Macbook 13inch late 2009 model
2.26 processor
4GB Memory
Many thanks
josh

In case anyone comes across this in the future, I've resolved my issue, and it had nothing to do with audio bit rates. In short, there seems to be a well-documented yet unfixed but in which an export from iMovie can lose sync if there are either slow-motion effects applied to a clip, or if the slow-motion speed is custom rather than pre-set by the software.
I changed my clips to 100% and everything exported fine, with no sync issues. For more on this, see the helpful thread here: http://discussions.apple.com/thread.jspa?messageID=10618532#10618532

Log and transfer MTS file and audio slip issues

I'm having 3 issues with a 30 minute project in FCE HD.
1. When I create clips in log and transfer, sometimes my footage chatters when I watch in in the viewer or place it on the timeline. It didn't chatter in camera, I checked, and it doesn't chatter in log and transfer. I can re-cut the clip in log and transfer but I'm trying to save time!
2. When creating a clip in log and transfer or just transferring a full clip, FCE trims the last 3 to 4 seconds off. I need these 3 to 4 seconds!
3. When trimming and razoring a 9 minute+ clip on the timeline, the audio begins to slip and continues to slip the longer I trim.
If anyone has answers to my three issues, please help. This project is frustrating in content and now it's frustrating in editing!
Thank you in advance for all your help!!

Sorry it has taken so long for me to get back to you. Again, thank you for taking the time to help me.
Your first question, these clips came from my Panasonic HMC 150 camera. I filmed at 24 fps. I downloaded the files from my SD card to my laptop, then use log and transfer to bring the clips into the project.
FCE only offers 25 fps or 29.97 fps. So, there is a discrepancy there. I'm not sure how to fix that when I want to stay with 24 fps. Yes, I can film at other frame rates, I just prefer 24 for what I generally create. Is there a plugin for more frame rate choices in FCE? Or is that just available in FCP?
Your second question, I always use insert. I only use overwrite for my title cards.
And finally, your third, I am aware of the destination tabs. I understand how they work. My issue with having so many tracks is that I am working on a laptop without a mouse and sometimes when I move a clip the timeline jumps and creates the extra tracks when I place the clip. I just need to be more careful when moving clips.
Now, as to my final issue and that is the trimming of the clips through log and transfer. FCE trims off the first and last couple of seconds and will not allow me to bring them into the project. Is this a setting problem or just inherent of FCE?
I look forward to hearing from you!

Audio slipping on XML export to FCP?

I've edited a project is Premiere CS5.5, and now I want to bring it into FCP for some tweaking. When I export the project using 'XML for FCP' the video comes through fine, but all the audio clips are 10 seconds later than they should be. I've tried a lot of variations on XML exporting and importing between the two programs and nothing works. The sequence in Premiere is 'DSLR' (the footage is from a Canon 5D). I've tried making a new timeline with different sequence settings and exporting, as well as trying a lot of different sequence import settings in FCP. (FCP is 7.0.3)
I cant just export the audio as one track, because I need it editable in FCP. Also, other projects have exported via XML just fine, so it seems to just be this one file with the problem. I even tried it on another machine and it had the same results. Is there a setting somewhere that I missed? Is there a standard sequence setting for importing Canon 5D footage from XML into FCP?
Is it just a bug? This is a professional job, and I'm running behind because of the week I spent trying everything I could think of to fix this problem. Anyone have any idea?

" Do you have any specific questions we might answer?"
Yes, as I stated in my first post-
1. The audio is slipping 10 seconds per clip on an XML export from Premiere to FCP. Has anyone has this problem and know how to solve it?
also
2. Is there a tutorial somewhere that details how to keyframe audio levels per audio clip on a time line (not just a whole track at once)
If anyone has any ideas on either, I'd really appreciate it.

Audio slips out of sync

Importing straight from my .mts or running through media encoder first (to .mxf), either way, the audio always slips out of sync. I'm testing Premiere CC currently to see if it will meet my needs, but I have little confidence it will with an issue like this. If other programs I'm testing (Vegas, Lightworks, and Edius) correctly detect my video/audio settings, why should Adobe be the exception?
The file is .mts from a Panasonic GH1, shot at 1080p 24 (23.976). This is correctly detected according to the sequence editor properties panel (although not as AVHDC). Changing to AVCHD does nothing to alleviate the problem, however.

First off, yes, I've tried importing the way described in the link(s). I've played with this endlessly it seems. I do have a workaround and can get my audio to sync, but it's very manual and time consuming if done on a large scale. I must unlink the audio (actually I'm usually working with a separately recorded audio file), and finagle the time/length/play speed.
What version of Premiere Pro? Include the minor version number (e.g., Premiere Pro CS5.5 with the 5.5.2 update).
Latest CC version 7.2.2 (at least it's the latest according to the CC downloader)
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
See above
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Win 8.1 64bit
What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime".
AVCHD .mts file from a Panasonic GH1 (both from a single file, minus the whole folder structure, and from one copied the "approved" AVCHD way from within the original unchanged folder structure)
If you are getting error message(s), what is the full text of the error message(s)?
None
What were you doing when the problem occurred?
Nothing special
Has this ever worked before?
Not from what I can tell (again, I'm trialing the software here)
What other software are you running?
Web browser sometimes, but same issue when nothing else is running
Do you have any third-party effects or codecs installed?
Well, yes, on my machine of course, but nothing I've put into Premiere
Tell us about your computer hardware. Be especially certain to tell us about third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU).
Core 2 Duo (I know, I know . . .), 8gb memory, NVidia GeForce GT 520 graphics card
Are you using Mercury Playback Engine GPU Acceleration?
Yes
Does the problem only happen with your final output, with previews, or both?
Everything, even before actually importing and simply viewing in the source monitor
Thanks for any attempts to help.

Premiere Pro Audio Slipping with AJA Kona LHI

I have noticed that when I run Premiere Pro CC (Latest updates) My audio playing back on the Kona and on the desktop will progressively slip out of sync when my Kona LHI card is enabled through the video output options. The sync issue goes away when the card is unchecked. The initial release of PRCC did not have this problem, but when the updates were issued soon after, the slipping issue cropped up. Anybody have these problems? Any suggestions?

I realize this is a year old but was this issue resolved?
For what its worth I've had/have similar problems with Premiere Pro CC and the AJA Kona LHi card. Just call AJA support 1-530-271-3190 and speak to their tech support gurus. Their folks are awesome. I just tell them what I'm trying to do and they will stay on the line and help until you can get things running again. No fees for customer support, nothing to register for... just call them and ask for help and they will!
I wish more companies operated this way.

Why does my audio slip out of sync when exporting?

I am exporting an HD edited video. I shot 1280x720 & editing in FCP 6.0.5. I am using APPLE PRO RES 422 1280x720 30fps 48kz . Should it be (HQ)?? - I do not select re-compress all frames or make self-contained. I just want a QT reference file to view and then burn a DVD. My clip is 43 minutes long. HOWEVER, the audio drifts out of sync BIG TIME. Why is that??
Here are my sequence settings:
1280x720 Aspect Ratio HDTV 720p (16:9)
Square Pixels
H.264
Audio at 48kHz

That's what I thought, however, when I play back the .mov file after exporting using "current settings", that's when I experience OUT OF SYNC audio. Do I ignore that and drag and drop that file into iDVD and let iDVD crunch it??? Is it just the playback of that .mov file that is out of sync?

Audio sync slip in CS6, gets ahead of visual every few mins

My audio gets ahead of visual, whether import from tape or file. Thought at first it was due to old projects from CS2, but it does this regardless, anyone had and solved this problem?

More Detail. Recently installed Full Master Collection Suite CS6 PC version into a brand new PC with 64GB Ram 4.5Ghz CPU on a ASUS Sabertooth X79 m/board, GeForce 680 graphics, SSD for programs and 2x 3TB HDs for storage. Very little other software, not even Office as didn't want to effect video editing. Don't use internet so can't get virus attacks, so haven't done an update unless I did one at install time which was a few months ago.
I record with JVC-GY HD 100 and 250 cameras which record on mini-DV tape and Hard Drive which I import as MT2 format. I'll do some tests but I think the audio slip is on both MT2 files and tape captures alike.
Never had this problem with previous verions of Prem Pro such as CS3. It clearly gets effected drop a frame drop occurs, I get a RED frame and half of another nearby frame corrupting a frame quite often even on brand new tapes, that usually instantly un-synch's audio by a second, but even when I haven't spotted a dropped frame it creeps out of synch after a few minutes.

Send to Motion - audio and video not in sync

I'm using FC Studio 1 on a new iMac 2.4GHz Core 2 Duo with 2Gb memory. I've noticed that when I send to 'motion', my audio slips, losing the first second or so resulting in an un-synced clip.
Does anyone know why this is happening and what I could do to rectify it. At the moment I'm working on a project where i'm only dealing with the text etc on picture, so the sound sync is not a huge problem, but would be nice to know why it's doing it and what can be done.
Thanks

Um ... some useful data?
OS/CPU/RAM/GPU/vRAM ... version of PrPro ... and other programs or plugi-ins/3rd-party apps involved ... footage type/codec/wrapper ... such things would be very useful.

AUDIO SYNCH PROBLEMS

I have never had an audio synch problem 'til now. I am running 10.5.7 on a 2.8 GHz Intel Core 2 Duo 4 GB ram, 24" imac.
iMovie 6.0.4
I have a 50 minute heavily edited project with many transitions, etc.. I have no problem with the footage downloaded from my Sony HD camcorder. I even saved many individual frames as pictures and changed them to the beat of the music in the timeline and all worked perfectly. BUT, my problem is with the "video trailers" I slipped into the timeline. The audio slips when I play back in the timeline AND when burned to DVD. BUT, it does not slip in the same place every time I preview it. If I scrub the playhead back over some of the bad scenes and play them again, they are in synch. IT KEEPS CHANGING..... When I export to a desktop movie to review - the synch problem is there and some of the audio is missing. This only happens on "movie trailers" I have downloaded.
I can't figure out why it keeps changing in the timeline and then correcting itself when I back up and play it over again. I AM GOING CRAZY........
Thanks in advance for any suggestions.
Wally

Thanks for the reply but my problem is not with iDVD - it is with iMovie - when I add "trailers" to it they go in and out of synch at different places everytime I review it before moving on. When I scrub back over the problem area and then play again, they are perfect for one time and then I try again and they are not synched. The problem is in iMovie.
Thanks,
Wally

Audio out of sync - Finalcut 7, Canon 7D, Marantz PMD 670

Having some serious audio slip (out of sync) issues - looks like some people already have this using various equipment (h4 zoom, Tascam, Olympus etc):
Shot an interview with Canon 7D
Recorded audio on a Marantz PMD 671 and converted to 48Khz (several times in Compressor, QuickTime Pro 7, Bigasoft Audio Converter):
MacPro (2008) - running 10.6.8
Finalcut pro 7.0.3
When I import both the video and the audio from the two sources they are fine at the start of the audio sync mark, but slip badly after a few minutes.
Have exported the audio in different AIFF ways 44Khz, 48Khz, 16 bit 32 bit, little endian etc, but it fails to sync up.
Have had a look at the forums on Creative Cow, but this just says to adjust the speed settings of the audio to 99.89%. This is almost fine.
Another thing I found is when I scrub through the audio track from the camera, the waveform syncs up with audio I listen to it, eg I see a spike and corresponds to a loud pop sound through my headphones
However...
When I scrub through the audio from the Marantz, the waveform does not seem to reflect what I hear, eg I see a quiet passage but can clearly hear audio at level 10dB.
I've restarted, updated, everything.
Lost and frustrated of Cheam

OK FIXED! This is what you need to do:
These THREE steps will work if you have shot video and audio from TWO separate sources, eg:
- Video shot on a DSLR (Canon 7d in my case)
- Audio recorded on a digital recorder (Marantz PMD 671 - in my case, Zoom h4n etc)
1. DON'T PANIC! - Make a fresh brew, and sit comfortably
2. Delete or (better still) rename your FCP prefs. I suggest instead of deleting the prefs, add ".OLD" to the end of the file name. In the unlikely event this doesn't work, then you might need to put your prefs back.
This is an extract from Apple support page :
Delete the User Preferences
You can resolve many issues by restoring Final Cut Pro 7 back to its original settings. This will not impact your project files, but you should verify your Scratch Disk location setting after doing this. To reset your Final Cut Pro 7 user preferences to their original state, do the following:
In the Finder, go to ~/Library/Preferences—the tilde (~) represents your Home folder.
Remove the "com.apple.finalcutpro.plist" file from the Preferences folder.
Remove the "Final Cut Pro User Data" folder from the Preferences folder.
Restart your computer
3. This is the crucial step from Michael Gissing Creative Cow (nuff respect bro):
http://forums.creativecow.net/readpost/8/1151955
I used QuickTime Pro 7 to export the original "Original" WAVE file to an AIFF 48Khz, 16-bit audio file. But you can use SoundTrack Pro, Bigasoft Audio Converter. As a side note, MP3 are notorious for a slippling - this AIFF conversion will normally help.
This will fix your audio slip if you find you have had to adjust the speed (eg, 99.89% etc).
