Audio is in-sync in Premiere but out-of-sync in export

Hey everyone,
I have two audio sources and one video source in my timeline, one is linked with the video, and one was recorded externally. The external recorder, for some reason, records ever-so-slightly slower than real-time, so even when I sync up the very beginning of the hour-long video, the end will be very slightly (but noticeably) off. To fix this, I just change the speed/duration of the externally-recorded audio so the two audio sources are in-sync with each other (and the video) for the entire show. However, this is where the problem lies.
The speed change, I think, is just too small for Premiere. It ends up being about a 10-frame difference, so the speed % is less than 100.01. When I make the change, the audio is perfectly in sync when I just hit play in Premiere on the timeline. But, when I export to anything (H.264, WAV, etc) I think Premiere just rounds it to 100.01% exactly, because the audio is then out-of-sync. I've tried rendering audio first, then using previews in the export; deleting rendered audio and having it render in the export - nothing seems to work. In fact, even when I make small changes to the speed/duration so it sounds different in Premiere, the export will sound the same.
Is there some setting that will allow Premiere to change the speed/duration of audio more exactly, just like when previewing in Premiere? Or am I stuck trying to figure out the exact time difference and changing the audio in an external program?
P.S. This occurs both when exporting straight from Premiere and using AME. And CS5.

Bump?

Audio won't play in Premiere, but plays in QT, FCP, and Adobe Bridge.

Hi everyone,
I'm normally pretty good at troubleshooting, but this audio issue has me scratching my head. A cameraman had DVCPro tapes transferred to QT movies. All the clips playback fine if opened with QT, FCP, and Adobe Bridge. Import these clips into Premiere and there's no audio. Nothing shows up on waveform- there's nothing there.
I would switch to FCP, but I already started the project in Premiere (CS 5.5) with earlier footage- which were mxf files right off the P2 card. That works fantastic. The footage I'm having an issue with was footage that was just shot recently on DVCPro tapes- so switching to FCP isn't the most time efficient. But I'll do it if I have to.
What confuses me the most is that the clips play back fine in Adobe Bridge, so I don't think it's a codec issue.
Thanks in advance for any help or advice getting to the bottom of this.

I had a similar problem, I'll tell you how I solved it. Understand that I am a newbie at video editing and Premiere Pro. I shot videos on a DSLR (.mov) and then transferred them to my computer. I then imported them into Premiere CS6. The videos played fine, and the sound bars indicated that audio was playing, but there was no sound. The clips I imported played fine in Windows Media Player. I did everything suggested on the forums, but to no avail. Then I thought of something no one else had suggested, and it worked!
I ordered my Rain Stratus computer already set up with Premiere CS6 installed. When I opened a new project, it by default chose Black Magic Design presets, since that is the video card I have. Being a newbie, I just went with that. But since the video I was importing was not captured by my Black Magic video card, it was the wrong choice. It took awhile to figure out, but I finally realized I needed to choose Digital SLR as the sequence preset when I created a new project. Then the audio worked!
One more thing I had to do, though, before it worked: in PremierePro, go to Edit/Preferences/Audio Hardware. I had to change the hardware from Black Magic Audio to Premiere Pro WDM Sound, click ASIO settings, choose my speakers, and then check the box marked "device 32-bit playback" (even thought I have a 64-bit computer.)
I hope that helps someone else from going through the same frustration.

I am trying to edit a .mov video in Premiere Elements 12, but the video and audio do not sync. They work fine when played in Quicktime.

Hello,
I am trying to edit a .mov video in Premiere Elements 12, but the video and audio do not sync as soon as I load it into the program. It appears to work fine in Quicktime.
Thanks in advance.

mbgoodwi
Thanks for the reply. This is the plan.
Open Premiere Elements 12/12.1 to the Expert workspace.
In the Expert workspace, go to File Menu/New/Project and Change Settings.
In the Change Settings area, select the project preset
NTSC
AVCHD
AVCHD LITE 720p30
OK out of there. In the New Project dialog that appears, note that it has your new project preset named.
Be sure to put a check mark next to "Force Selected Project Setting on This Project". And, then OK out of there.
Back in the Premiere Elements 12 Expert workspace, use Add Media/Files and Folders to bring your video
into Project Assets. From Project Assets drag your video to the Timeline Video Track 1/Audio Track 1.
Is there an orange line over the content in the Timeline. See screenshot for orange line to which I am referring.
There should be no colored line over the content if the project preset matches the video properties. But, if you do see
that orange line, then render the Timeline content by pressing the Enter key of the computer main keyboard or press
the Render button above the Timeline.
Do your video/audio now play back in the Edit area monitor in sync?
Please let us know the result, and then we will decide what next.
Thanks.

I have adobe Premiere Elements 13. It will not let me delete audio or have it fade in or out. I can move the yellow line all the way down till the volume reads -0.0, but the sound is still there on playback. I can click on fade in and fade out and the yellow line that graphs volume takes a sharp raise or dip at the beginning or end of the clip, but there is no change in volume when I play back. What am I doing wrong?

rickeyt
Thanks for the reply. Great news about the volume adjusts.
Now about those fades for the volume. How are you doing that?
1. Right click the Timeline video audio and select Fade and then
see the Fade options (I had a video with audio file, so I saw the choices as shown in the screenshot)
2. You can also create two volume keyframes at each end of the Timeline audio clip rubberband (orange line that goes horizontally across the middle of the audio clip). At the position of the Timeline Indicator, click the Add/Remove Keyframe icon, and then with the mouse cursor position the white dots (volume keyframes) to achieve the Fade In and Fade Out audio. In the screenshot below I have moved the Timeline Indicator so that you could better see the white dots (volume keyframes).
Please let us know if any of the above works for you with regard to the audio fades.
Thank you.

Audio/Video slightly out of sync after exporting media and trying to watch on iPhone

Hey adobe tech heads
So, I recently upgraded to the new Adobe Premiere Pro CC, from Premiere Pro and I have to say that there doesnt seem to be any difference to the normal functionalites. While I am merely a beginner, i suppose there are more complex features that i have yet to discover.
But let me get to the point of this discussion. I have been making a few fun videos for friends of mine of their childrens birthday parties and such. I have a Nikon D3200 which is a 24 megapixel camera for images and have been shooting 1080p for the video, which i think uses 25 frames per second. (Dont quote me on that one as i am still learning all this techno-jargon). I was, in the beginning, having a slight issue with choosing the correct sequence settings in the beginning, but eventually managed to figure out that for my Nikon, i was choosing the DSLR, 1080p, 25fps option. So far, all seemed to work well, everything synced up, rendering the files often, and creating a fun memory for the parents, of their childs birthday party.
Then is comes to exporting. I would just select "Media" and then "Export" which would bring up the Export Settings Menu. I would simply press the Queue button, and then in in the Queue section, i could choose to make a video file typically for Youtube in HD. Before posting this discussion, I did a quick youtube search, so not to waste all your time, and found this link of this guy who not only showed me that i dont need to Queue it up, and can direclty select Youtube HD from the Export Settings menu which i will try, but he also confused the #%^&$(*& out of me with all his bitrate settings talk (this part starts around the 3min and 32secs mark into his youtube tutorial) - http://www.youtube.com/watch?v=j2j5dnlDmos (The reason I am showing you this is because now, i am not sure if this is what may cause my slow phone/tablet issue)
So here is my problem - Once i edit and export the file into the youtube 1080 25fps HD option, I open this new exported file on my pc and it works fine, perfectly synced and ready to share. Once i have uploaded it to Vimeo, which is my preferred social media network, it uploads fine, and on any normal pc/laptop, there is no problem and it runs just as smoothly as when it was edited. Although i noticed that the video seems to be playing at about half a second behind the audio when trying to show someone on any iPad/tablet or any mobile phone. I recently made this clip as a tester and to be able to show you awesome braniacs, because its kinda pissing me right off, that the video isnt perfectly syncing into the audio on the phones and tablets, but works just fine on a PC/Mac. I specifically made a point to match the images up to the beats of the songs, and if you watch where the little kid climbs up the indoor rockclimbing wall, this might help you understand my frustration. check the below link on your pc/mac, and then again on your phone and you will see what i mean. I even played them simutaneously together and you can see the delayed video on the phone/tablet than on the PC/Mac.
Any help would be greatly appreciated on how to fix this, as while its doing my head in, i am sure for you guys, a simply change on my lack of tech knowlege, will probably have us all smiling! Here is the clip - https://vimeo.com/7105289
Thank guys. I look forward to your replies

First of all, when you export, you should see the dialog box that has information about the source video as well as the export. If you are shooting 25fps then you are not in the USA. If you are in the USA, look harder at your export settings.
But that isn't the problem you are facing.
Are you using the Vimeo app to play the videos on the iPad or are you just playing it in a browser? Use the app if you aren't now doing so.
I doubt that you are using anything other than AAC for your audio from what you have said about using the presets, but I have to ask. You are using AAC, right? That is what Vimeo prefers.
Have you tried turning the HD off in Vimeo to see if that clears up the problem? That will probably be fine on a smartphone. An iPad might see the difference though.
You are not going to be happy reading this Vimeo.com thread, but here it is anyway.
I don't even know what to make of this one.
In any case, you will read for yourself that you may want to change browsers on the mobile device.

HELP! Audio goes out of sync after export!

OK, folks. I need your help. I have a looming deadline of THIS FRIDAY to hand this in.
I have a finished multicam edit of a show that runs 1 hr 20 min. It plays back perfectly in the timeline, all video and audio perfectly in sync. Looks and sounds exactly like what I need.
When I export the video as an H.264 file, the audio gets out of sync with the video by 13 frames! But that's not all... It doesn't happen to the entire audio track. There's about 50 minutes in the middle of the video where the audio goes out of sync. The audio at the beginning and ending of the video is lined up perfectly in sync. It's just the middle section that gets screwy.
What do I do?!
This has never happened before, and I've worked a lot with multicam in Premiere Pro CC before this. Never been an issue. I tried uninstalling and reinstalling Premiere, and also deleting all media cache files, but still no dice. I also tried copying the clips into a new sequence in the same project, copying the clips into a new sequence in a NEW project, nesting the sequence... nothing works.
My setup:
MacBook Pro Retina (Rev. A)
Premiere Pro CC (latest version)
Panasonic GH3 footage in 1080p 24p AVCHD timeline
3 cameras & 1 audio WAV file in Multicam
Any help would be greatly appreciated!

OK, I figured out how to fix it:
In Premiere Pro CC, click on SEQUENCE > DELETE RENDER FILES.
Try exporting the movie again.
It worked! I exported the same sequence, and it took a long while to re-render the audio files, but when it was finished exporting the audio and video were in perfect sync. I'm not sure what caused it, but this fixed it, so hopefully anyone else having this issue can save a lot of time by reading this.
Cheers!

Video and audio do not sync after importing media into Premiere Pro

After I import my video which is in the .MOV format, I notice that the video is slow and out of sync with the audio. This makes it incredibly difficult to edit. Any and all solutions will be helpful.
Sincerely,
SheIsInquisitive

John:
Thanks for your reply. Excuse my referring to you as "Kevin". I'm new to the Adobe Community. I have also referenced another article which is seemingly a bit easier to fix for such a non-technical woman like myself. I'm going to try both solutions. Whichever works I'll be sure to reply to the thread with my findings. I found this article which provides the following solution: http://blog.flickharrison.com/2012/04/problem-solving-in-adobe-premiere-audio-glitches-and -sync/

Rate Stretch audio goes out of sync when exported.

Audio, which is rate stretched using the rate stretch tool to 100.01%, plays fine in Premiere Pro CS6. However, when exported to Encore or to MPEG-2 file, the audio is no longer stretched and becomes out of sync by the end of the video. When I play the preview in Encore, the audio is out of sync. Switch back to Premiere, it is OK. Export a MPEG-2 file and author a DVD, the audio is out of sync. Go back to Premiere, it is OK. I record the audio using a TASCAM portable recorder. I have recorded and synched audio many times and this is the first time that it does not work, on two separate Premiere projects. Any ideas on how to fix this. Even better, is there a way to record audio so that it matches the video (from a Panasonic HD AVCHD camcorder) without requiring rate stretch adjustment?

Try changing the speed with right click, Speed/Duration instead of using the Rate Stretch tool.

Eric,
Thanks for your reply. Realtek audio works only in playback. There is a stereo mix in the mixer but the recording controls are not operable with no sliders in the mixer for any recording option. Slider controls appear to be grayed out. Can't figure out how to enable them. Downloaded newest drivers to no avail.
The M Audio control panel has no apparent option for recording stereo mix. Adobe ignores the sound from the DVD or CD and shows flatline.
I'm trying to record the sound from the DVD not rip the track.
When I go to Audio Driver Setup and select Audition 3.0 windows sound, there is no input device installed.
I'm thinking of going back to a decent internal Soundblaster card like I have on my 8 year old machine I am replacing.

Audio podcasts show synced in itunes but is not on ipod.

I connect my nano to itunes and try to sync audio podcasts by syncing under the podcast tab. itunes shows synced but podcasts are not on ipod. What can I do?

Where are you looking for these podcasts on the iPod?
Double check to make sure podcasts are configured to sync to your device from under the iPod's Podcast configuration tab.
To access the Podcasts tab for your iPod, plug your iPod in and click on it from under the Devices section in the left hand pane of iTunes. This will bring you to the Summary tab. Along the top you should see a Podcasts tab, so go ahead and click on it. Here you can configure how and what podcasts sync to your iPod.
If you do make any changes to do this tab, make sure to hit the Apply button in the lower right hand corner to apply the update changes to your device.
Otherwise, are you getting any error messages when you sync your iPod Classic with iTunes?

Audio no longer synced on timeline or preview panel after all editing was finished. HELP?!?

Ok, so I am editing a package that is about 8 minutes in length. I had pretty much finished it, save for a few minor touches here and there. I had decided to review it again today and behold, none of the audio was synced to the video anymore. It had been yesterday, as far as I know. It's not just off a little. It seems the audio from the end of the footage is now toward the front and the rest is all jumbled up also. The footage was shot on a miniDV 60 minute Sony tape and had imported just fine. The video file that was imported is still synced when played in Windows Media Player, but as soon as I import it to Premiere Pro CS5.5 it is just like the file that is out of sync. I have other packages on the same timeline from other tapes and they are playing just fine. I thought maybe I had moved the audio tracks separately from the video, but as I stated, even in the preview panel the audio is off.
I have attempted to unlink and relink the footage and have attempted to just start over from scratch, which I DO NOT want to do, and just add the same file to the batch and re-edit.
Is the file corrupt? Is it Premiere Pro CS5.5 that is messing up? Or is it user error that can easily be fixed? Do i need to reimport the footage from the tape to the computer instead of just the file to PP?
I have been working on this package for a few weeks now and would hate to have to restart it. If tere is a solution to this, other than starting over, I would greatly appreciate the help!
Also, watching through it now, the audio isn't only out of sync but also jumpy and it cuts in and out every so often for just a frame or two. This makes me think possibly the file is bad...

The footage was shot on a miniDV 60 minute Sony tape and had imported just fine.
In Premiere, you 'capture' from tape and you 'import' digital media files.
Was this DV footage captured from tape using Premiere?
You can try deleting your Media Cache files.
Edit > Preferences > Media
Under 'Media Cache Database' hit 'Clean'.
This will delete the Database only.
Navigate to the location specified under 'Media Cache Files',
open the folder, select all and delete.
The Media Cache Files and Database will automatically re-generate
when you re-open your Project... allow plenty of time for it to finish.
You can also try deleting your Preview files.
Project > Project Settings > Scratch Disks
Navigate to the location specified in 'Video Previews / Audio Previews',
open the folder, select all and delete.
When you re-open your Project, Premiere will ask for the location
of the missing Preview files... select 'Offline'.
Re-render the Preview files if needed.

Audio losing sync when exporting to .mov

I've been using Flash for a while now, but I'm still very much inexperienced with exporting .mov files, and this is the first time I have tried to export a large project that contained audio. The problem is that the audio plays faster than the animation, and is very much out of sync by the end, with the audio playing several seconds before it is supposed to. I have tried every setting I can think to change, and tried rendering the same .swf file in After Effects. However, in After Effects, even when I make sure to have audio in the output, the rendered video had no sound. All sound on the timeline is set to stream and not event.
Any help is appreciated. I honestly don't have much of a clue what I'm doing.

1.If you have placed your audio on the timeline, make sure you put everything to stream.
export a large project
2.Make sure your computer has a lot of processing power: playing and recording at the same time requires a lot of RAM/CPU, look for idle processes and shut them down.
3.If nothing helps, record Audio/Video seperately and match them afterwards in AfterEffects/Premiere
4.Flash has a maximum amount of frames it can handle (16000 := 10 Minutes), if your project is getting near to that limit, try dividing your project.

IMovie audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !

iMovie 11 audio issues. Fine in timeline, but when rendering to iTunes or Media Browser, audio from certain portions of movie files are heard in places where it shouldn't be !
I have created a project where I have a montage of photos and video clips edited together with music under. Some audio portions of the video files are being muted in some areas and those portions are being heard in another part of the project. This is not for all video clips only certain ones.
The project plays fine in the timeline, but when I render the project thru iTunes or Media Browser, this is when the project goes corrupt.
I tried detaching the Audio from the video clips and this somewhat worked, but the original problem still exists with certain audio still being heard where it's not supposed to be.

I have a fix - or rather, a workaround.
WARNING: It is lengthy, but still far better than starting a new project from scratch.
I had this same issue and none of my transitions/clips were at custom speeds, nor did I have anything else weird going on. Unfortunately there is nothing you can do within iMovie to fix this, at least there wasn't for me. iMovie is BY FAR the buggiest software I have ever used and if you haven't already spent hours slaving away on a project, you are so much better off using just about anything else to edit your video.
...But let's assume you have already spent many hours working on your project and you don't want to start all over. Well then, you have at least one option.
It's a pain in the neck, but it's infinitely better than restarting your project from scratch.
This will require:
A software called Soundflower (which is free) and some kind of audio editing software (I use Logic, but really any should work).
1.) You're going to need to export your video with the messed up audio. Typically if you're audio is messing up, you're video is at least usually working just fine (at least it always does for me).
2.) You're going to need to open that video in your audio software and import only the audio. If your software doesn't give you this option, then you're going to need to record the audio from your video using the audio software and Soundflower. You can find tutorials on how to do this, but it's honestly pretty straightforward once you start playing around with you Mac's audio I/O settings. Remember to have your computer's volume all the way up when doing this.
3.) Watch/listen to your video and make notes of where the audio errors occur. I HIGHLY RECOMMEND writing down times too, as they will be extremely helpful later.
4.) Now were going to rip some working audio from the iMovie project itself. Go back into your iMovie project and only play back audio while in the edit window for this step. Do NOT play your project back in full screen.
This part is key: if you try to play back your project from the beginning the audio will usually still mess up. So, what you're gonna have to do is go back on your edit window timeline right before these errors occur and play that specific clip back while recording this working audio with Soundflower and your audio software. Essentially we're only recording the parts of the audio where these errors occur, so try to do this in order if you can. Try to leave several seconds of audio in before the error - that way we can use it as reference when we construct our new audio track.
5.) Now in your audio software you should have your original error-filled audio track and the new clips that we just captured. This part can be painstaking if you're not familiar with audio editing softwares, but as you'll learn, it's really not that hard.
You're going to look at your original audio track and compare it to your new working audio clips. You should be able to notice where those new clips are supposed to go by looking at the identical (or close to identical) waveform shapes in your original audio track. The two should correspond with one another. If you don't understand what I mean right now, you will when you start playing around with the audio. This is why marking times is very important.
Take your new clips and split them up if you haven't already, that way you can drag them around and edit them separately from one another. Essentially your going to line these new clips up with original and then replace the original parts with new ones.
We need to get this as precise as possible, so start off by getting them as close as you can with your naked eye, and then use a zoom tool to zoom in as much as possible so that you can get them lined up PERFECTLY, or at least extremely close. In some softwares you can just drag these new clips on top of the old track, but most of the time you will need to actually cut out the old piece and replace it with the new one. In doing this, zoom in and make sure that you are NOT cutting out a bigger space than your new clip will fill - otherwise you will have small gaps in your audio.
VERY IMPORTANT: Also make sure that this new audio track starts at the EXACT SAME time as your original - otherwise your new audio will be out of sync.
I know this part can really suck if you're not used to audio editing, but at this point, there is little other choice.
6.) Once you are done with this, export your newly pieced together audio track.
7.) Now open iMovie and create a NEW project. Re-import the video that you exported earlier that has the messed up audio. This might take a while, so just be patient.
8.) Then right click the clip and select "Detach Audio". This will do just that - allowing you to edit the audio separately from the video. Now delete this audio.
9.) Now, import the new, perfect audio track that we just made and make sure that it starts at the start of the project. Make sure it's in sync and that everything works.
Now just export your new video with the working audio and you should be done. Since we have given iMovie the audio with no editing actually being done in iMovie, it does not have to generate its own audio now and you should have absolutely no errors now - unless there is some that you forgot to take out earlier.
YOU'RE FINALLY DONE!!!
I know this entire process *****, but if you're that far into your project, there is little else that you can do. Now you've learned your lesson:
DON'T USE IMOVIE EVER AGAIN.
I hope this helped!
