Audio is off sync towards end of exported film

I am having an issue which makes no sense so here goes... I animated a short piece which some lipsync in it. I exported it via the Media Encoder. It works perfectly at the beginning but the last two lines of dialog are off a number of frames which makes no sense. The preview in Flash works fine but when I render it the lines are off whether it's swf, flv, mp4 or any format Flash can spit out. Both CS 6 NAD Flash CC do this yet like I said if you play it in the timeline it's dead on sync.
The frame rate is the same in the file and the exporter so that's not it. I can't figure out why. Any thoughts? It was animated in Flash CS6 and then rendered in Flash CC because Flash CS6's rendering is a bucket of poo at best. Any help would be greatly appreciated.

Thanks for the tip but I was trying to avoid having to put the clips into a video editor because that tends to cause it's own problems with sync as well. I actually found my answer via an obscure link to some comment on a forum detailing that .wav files (which I was using) will NOT stay in sync in Flash (regardless of the version) due to the particular way Flash compresses them. I switched all the audio to .aif and bam... instant sync. It sure would be nice if the default sound format Adobe uses in thier own Audition program would be compatible with ther own software! After all, wasn't that what the whole unification of the Creative Suite was about? So that all of their 'suite' would work with each other seamlessly?

Capturing footage and audio is off sync?

I'm capturing footage and then play it back on the timeline. I notice that the audio is off sync, why is that? I use Sony DVCAM Deck to capture without altering the setting, in Final Cut Pro 6, and the audio became off sync. Any solution?
Thank you
Luis

Is it consistently off-sync? Like is it always 2 frames off? Or does it trail off, like it starts in sync and then it drifts out of sync after several seconds? I recently captured a bunch of stuff that was recorded with a DVX100 and the audio was 2 frames ahead of the video (sometimes it seemed like it was only 1 frame off, but 99% of the time it was 2).
Then another problem that crept up was when it got to the end of a tape, which would confuse Final Cut. It would stop, and then make the last clip captured play at 29.97 when it should have been 23.98, though the audio would play back normally. So it would appear to be in sync for a moment and then it would get way out of sync very quickly. What I had to do then was just babysit the capture of the last scene on the tape and stop it before it got to the end.

Only some audio is off sync after Quicktime export

I am cutting simple man-on-the-street interviews together to build a narrative. I am shooting on a Sony HVR-V1U in HDV. I import everything fine, edit it, then export to QT using the following settings:
H.264
Video bitrate: 1372 kbits/sec
Frame rate: 29.97 for 25fps
Frame size: 640x360
Multi-pass
Quality: High
Sound: Format: AAC
Sample rate: 44.1 kHz
Stereo channels
128 kbps bitrate
When I play the QT, some of the voices are fine, but others the video is off sync from the audio by around 15 framse, and I have NO IDEA WHY. I've tried messing with the settings, re-importing, and nothing works. And the fact that it happens to some clips and not others, has left me just baffled. I've had to just re-export manually adjusting the audio. Anyone else have this problem? Any solutions or advice that I could at least try?
Thanks!
Mike

Audio always off sync after converting .asf files?

Hi, my problem is that it seems that every time I convert .asf files the audio always ends up off sync. Many programs don't even convert them at all, like ffmpegX, but my favorite video converter VisualHub does convert, but like I said before the audio is always off sync. Does anyone know of any software that can reliably convert .asf to another video format without the audio messing up?
On a side note, I do have plug ins such as Perian and Flip4Mac that allows Quicktime to read the files just fine, it's converting them that causes problems. For reference, the particular files I'm having trouble with use the WMV3 video codec and wmav2 audio codec. I think that's the problem.

My problem is a bit different, though just as irritating. I can't believe Adobe hasn't fixed this given how long since the original post has been up here. I capture satellite programming from a professional c-band satellite every week. I use good old fashion Quicktime to capture 30 minute programs for later broadcast. Our job is to capture the video from the satellite, clip the commercials at the beginning and end of the program and then export a clean version as an MPEG2 file. Quicktime provides two capture settings: high (which provides a very large ProRes file in 16bit stereo) or medium (which provides a manageable H264 file in AAC stereo). Both are Quicktime files.
While I don't have sync issues with the ProRes file, the file that is captured using H264 and the AAC stereo gets pushed out of sync by just enough frames to make it necessary to fix. This is adding about 2 to 3 hours of studio time each week to our production given we have to process about a dozen of these files. Viewing the original quicklime files using the newest version of quicklime or the old Quicktime program and most other video players yields a perfectly in-sync experience; it's just when it's imported into Premier Pro CC 2014 that the sync. problem appears. One solution that has worked is taking the master file and exporting it again as a .dv file, but this actually takes longer than fixing the sync issue within Premiere. My guess is it may be the AAC audio process that may be the problem.
We only started using Premiere a few months ago and are already re-evaluating whether we should return to FCP. We were really like most of the Adobe apps within Creative Cloud, but we use Premiere to much to put up with such a major flaw. I do wish Adobe would monitor some of these forums; they have no idea how customer service plays a key role for future software purchases.

Audio cutting off at the end of audio clips w no change in waveform?

Audio cuts off right at the end of some of my clips... I can still see the waveforms that have the full audio on them, but no audio plays for those last two or three seconds! My audio level is the same throughout the clip, so its not like its fading out or anything. This has been happeneing for a few weeks now, in multiple seperate projects.

Hi David,
Thanks for the response. I did look at the song that got cut off and it's a .m4a file. However, I also have normal audio that comes from an external Zoom recorder in .wav format that is getting cut off in the same way. The strange thing is I've never had a problem with this before a couple weeks ago. I've used this same song before and my external audio is always in .wav format

Audio is off sync with videos on Ipod Touch.

My Ipod touch does not want to seem to play the audio in correct sync with my videos anymore. I have not done or changed a thing lately. Does anyone have any ideas? Thanks. I am running firmware 1.1.5

Update My iTouch is downgraded to 1.1.5 successfully. I used a pc that had an un updated version of iTunes installed (7.6) and after 2 attempts using the power off + home combination described in the firmware 1.1.5 post, I was able to successfully "restore" to the latest "1.1.5" iTouch software. When the touch reset, before establishing a sync relationship with the pc, I reattached it to my mac and selected "new ipod" rather than restore from backup. I then synced and tested on of the previously screwed up videos. It plays without any audio sync problems. This processes is more or less what the genius bar instructed me to do. I was reluctant to download any software not coming directly from apple. If anyone knows where the firmware file is stored on iTunes PC version, I would greatly appreciate the location. I want to save the file on my mac now that I know this is a good version. When Apple comes out with 2.1, I want to have a fall back.

Audio Track off sync after importing RAW Materials to Premiere

English:
Hi there i have the following problem in Premiere pro cc:
I record Let's Play Videos via Nvidea-Shadowplay in 1080p / 60 fps / 30.000 kbps
I checked the material in VLC-Player and everything is fine.
Now i drag and drop the File in Adobe Premiere CC and the Audio track seems to be off sync.
This differs. Sometimes the Audio seems to be beheind, and in other cases it is a to early.
This is a serious issue for me, because it leads to lot of post-production in audio tewaking to fix this.
I have no Idea how to fix this, because the RAW Material i recorded works perfect, but the file is to big
to put on youtube, ofc.
Deutsch/German:
Hallo Leute, ich habe folgendes Problem:
Wenn ich Let's Play Videos in Shadowplay aufnehme und mir das Material dann im VLC Player betrachte sind Audio und Videospur 100% synchron.
Wenn ich das Material dann aber in Premiere Pro reinziehe habe ich bei manchen, nicht bei allen Videos das Problem, dass die Tonspur asynchron ist. Manchmal ist das Bild zu früh, dann wieder der Ton.
Das führt zu viel Zeitaufwand beim Nachbearbeiten.
Wenn ich das Video dann Raus rendere ist es immer noch Asynchron.
Ich habe keine Idee woran das liegen könnte...

What you're running into is variable frame rate (VFR) video. ShadowPlay and any other app that uses nVidia's hardware h.264 encoders will produce MP4 files that are VFR. Premiere Pro doesn't handle VFR vids very well at all; it's designed to handle constant frame rate (CFR).
To fix this, you'll want to transcode your MP4 files using something like Handbrake over to CFR versions. I've never used Handbrake for this, but I know others here have to great success. Search for phrases like "VFR" and "variable frame rate" and you should find a bunch of results.
I solved this using the ffmpeg command line application, which you can search for and download from various places.
ffmpeg -i <input.mp4> -hide_banner -vsync 1 -crf 19 -r 59.94 -vcodec libx264 -preset ultrafast -g 50 -acodec copy <output.mp4>
If you'd rather use a GUI, then check out Handbrake or other tools.

Audio out of sync in Quicktime on export from Premiere

Currently using Premiere Pro CS3 3.2 and Quicktime 7.5.5
When I export to a quicktime .mov, my audio is a few frames out of sync. I've tried downgrading to older versions of quicktime with no success. Everything is completely in sync inside Premiere. If I import my rendered out-of-sync .mov back into Premiere, it magically syncs up fine again. It's the weirdest thing.
I don't suffer this issue when exporting to Real Media or .wma.
My machine is an Intel Core 2 Duo 6700 2.66, 2 GB Ram. Running XP Pro 2002 Service Pack 3. Premiere Pro CS3 3.2, Quicktime 7.5.5.
I'm using .mxf files shot on the HVX-200. My source video is 1280 x 720. I'm exporting using the h.264 codec. I'm fairly certain that it isn't the footage. I tried syncing up some color mattes to music in a new short test project and I'm still 4 frames off.
I thought the problem might be the use of mp3's but I replaced them with .wav and .aiff files and still the same problem. When I export to quicktime, the audio is 4 frames ahead of the video. In order to make it sync up, I have to move the audio four frames to the right. This is a terrible solution

Thanks for responding. We did record at 24pn.
However as a test, I started a new project, loaded a piece of music (.wav), and created some plain color mattes in Premiere. Then I synced up the colors to change to the beat of the music. An export results in the same problem, so best that I can tell the issue is independent of the camera.

Audio out of sync near end of 2 hr import of hi 8 tape

importing old Hi 8 into imovie 09, by the end of the 2 hr import, the audio is out of sync with the video when i play it in imovie. Any suggestions?

Import in smaller chunks of data (under ten minutes each).
It may be caused by 12 bit audio samples in the source files.

Audio is not synced with video after Exporting QuickTime Movie

I have Canon DSLR footage shot 24p/1080p on the timeline. Timeline settings are the same as the Canon footage settings.
When I Export a QuickTime Movie, the audio is out of sync...
Can someone please help with this issue...
Thanks,

Don't tell me...you edited the files the camera shoots without converting, right? The camera shoots H.264...FCP doesn't like to work with H.264. The problem is that it SEEMS like it will work, but really is rife with issues when trying to work with it. You have encountered one...loss of sync.
The proper workflow is to convert the footage first...
#51 - Canon 5D MkII / Canon 7D footage into FCP
Shane's Stock Answer #51 - how do you bring in footage from the Canon 5D and 7D cameras into FCP to edit?
You need to convert all of the Canon 5D MkII footage from the H.264 format that it records, to ProRes 422 (ProRes HQ is unnecessary...no quality difference) Yes, the file sizes get drastically larger. H.264 is an acquisition and delivery format, not an editing one.
You can use the Canon EOS Log and Transfer plugin that works with the 1D, 5D and 7D cameras. This plugin is great because it brings in the camera's TIME OF DAY as timecode, instead of starting each clip at 00:00:00:00 like Compressor or other conversion software will do.

Here is a tutorial on how to use it:

And the workflow for tapeless ingest into FCP:

But for a quick fix...change your SEQUENCE SETTINGS to ProRes...render, and then export.

Qt files audio out off sync in FCE 4

Export from iM6HD-expert settings(DVCPRO) out of sync.
Export from iM6HD-Full Quality and out of sync.
Imported a high quality H.264 clip and audio in sync but needs to be rendered(FCE said 6 hrs for a 20 min clip. and not what I want to do anyway.
Tried to open iM^HD project package and used "save as" in QT. Audio in sync but way to much to render. Also tried to export the audio as a seprate AIFF and no sync.
Thank you kindly

The MiniDisc comments are interesting.
I was first made aware of the MiniDisc's potential when a few years ago a club member demonstrated how over a ten minute test it only drifted by 1 frame.
Then a couple of years ago another chap demonstrated his Digital Voice Recorder which was perfect.
Apart from being a fraction of the cost of a radio mike they have a number of advantages as there is no chance of reception problems and you also have the original audio from the camera as (poor quality) backup should the radio mike fail.
Anyway my slight audio drift is no real problem apart from wasting those five seconds altering the speed in FCE !

Audio out of sync in M4V file exported from QT

Hello there,
when I export an .avi movie to (iPhone) .m4v from QT, I get an out of sync encoded movie !
After testing with 10 different .avi files, I have the same problem evey single time I encode an .avi to a .m4v...
Before I updated to 7.6, it used to work perfectly
So I have tried to encode these .avi movies to .m4v/.mp4 with FFMPEGX or with MPEG STREAMCLIP, I've updated the Perian Codecs to 1.1.3...
And it doesn't work neither...Even with these apps I'e got sound out of sync.
Please if anyone have solved this problem I would really appreciate knowing it.
Thx
K.

Same issue, but only every once in awhile. And it doesn't seem to be random for me. I try to convert to AppleTV format, m4v as well. The same movies will always fall out of sync no matter how many times I try.
I rip my collection of DVDs straight to AVI because I like the quality, but then make AppleTV ones for viewing on that device. Pixar's Bolt and Wall-E fall out of sync, as well as Pineapple Express and Shawshank Redemption. I've tried multiple times.
Luckily, I just re-ripped from my DVD using handbrake into the proper format and it worked. But it's still annoying. I don't like keeping the m4v when I'm done so I sometimes have to rip again, but I'd rather just convert from my AVI files i keep.

Audio out off sync

hey all I have been working on the Doc now for over a year the footage was all fine in till yesterday when the audio for everything is 3frames to slow, we shoot it on the dvx100b, I have tried making new projects new timelines and I have deleted the P list for FCS several times and nothing any help please.

Do you mean that the audio is constantly 3 frames late?
If so, are you sure you're monitoring the audio in the same "path" as the video? For example, if you're looking at the picture on an external VIDEO monitor routed via firewire thru a camera or deck, make sure the audio is also being monitored via firewire. If you're monitoring the video on the computer screen, make sure your audio is being monitored thru the Mac.

Audio off Sync with Video Podcast....

Somehow I always have trouble downloading Video Podcast. I Usually find myself having to download each episode 3 or times because iTunes hardly gets it done the first time, and when It's done successfully, the audio is off sync with the Video. I have the latest version of iTunes
Custom Windows XP

I've seen that problem in several threads, both here and in the Mountain Lion forum. I tried to replicate the problem but was unable to do so... so it's not a problem effecting all Macs. Try posting here - in the Mountain Lion forum - and see what you get as a search. There's one specific "More Like This" to the right on this thread but there doesn't seem to have been a solution posted.
Good luck,

Timing goes out and audio cuts off at end of published slide sequence

Hi
I am experiencing a problem with timing and the sound cutting off at the end of a slide sequence.
Here is my work flow:
I record what I want my slide show to say, add my music and sound effects in Soundbooth. I then create a mp3 file for my slide show.
I adjust my slide show timing to match my voice over, ensuring that the total number of minutes and seconds the slide show equates to matches the length of my audio. I then import my audio into my project while maintaining the slide timing.
If I preview the individual slides to match the timing of the arrival of words or pointers in my presentation by pressing the play button in Captivate, everything is great.... until I publish to a .swf file.
On a 2m:50sec slide show of 22 slides it cuts off approximately 5 seconds before the end. My timing which I have bent my brain on getting right, is out and appears to worsen the longer the slide show is or if it is not on the latest and greatest Mac powered computer.
I have gone so far as to increase the length of time on the last slide 5 seconds beyond the length of time that the audio occupies as well as adding another 5 seccond blank slide and still have the same cut off problem. No ideas how to help the poor souls who might not have an amazing computer to watch the demonstration on?
Interestingly if I publish and look only at the last 3 slides or if I look at a short sequence of slides or at a slide in isolation, my audio is there as it should be along with the timing. It would appear that the time "lost" or a lag between the presentation and the audio is the culprit.
Kindly advise if there is a solution to this or whether the problem lies with something I am doing.
Thank you in advance

Has there been any new developments on this problem?
I've been having to do some crazy work arounds to avoid audio cutting off at the end of slides when using CP5 for development.
Then this week I had to review an old training which was published a long time ago only to discover that the same issue of audio cutting off is happening there.
These materials were developed using CP4 and some even with CP3. This means that the problem/change is not CP5 but probably something to do with the Flash player version because at the time of publshing the older files did not have this issue.
This has me really worried. There is no way I can go back and update all the old files and it means that previously perfect materials are now being viewed with audio cutting off.
Have the Adobe Captivate developers considered the possiblity that this may be a flash player issue? Have you discussed this with the Adobe Flash developers? Will there be a fix for this anytime soon?
Thanks,
Aimee
