Video and audio sync

I am currently having issues with the audio for shows and movies being out of sync while playing only through ITunes. I have Windows 7 and am using the Asus P6T motherboard's Realtek audio. I don't have any issues playing through windows video player, just iTunes and quicktime. I've tried all of the FAQ recommendations to include turning off sound enhancements and updating software for motherboard audio. Does anyone have any other ideas of how to get the audio and video to sync? Thank.

What are you editing, and does your project match your video?

Video and audio sync when viewing clips online

When viewing clips, like on youtube, the graphics start playing, however there is no sound, only after a few seconds the graphics freeze and the sound that was missing starts playing and the graphics resume when they're in sync again.
Also when I pause a video and click play the clip will not resume and I have to click the "time bar" and then it will play.
My 13 MB Pro starts furiously blowing the cooling fan and consuming battery life when viewing clips on most video sites.
How can I fix these things?
This already happened before upgrading to Lion, btw.

Are you capturing this thru the LS? and what is the format you are digitizing? DV? or uncompressed? Would be best I'd think if you don't capture audio and video as separate files too. That leads to problems especially with DV captures.
How are you monitoring the audio and video? all from computer or? You could be in sync and not know it if you are using computer speakers for monitoring audio when watching video externally for example.
If you monitor both from the computer and it is in sync, but not when you record to video, I'd suggest that you export a self contained movie of this material and import that for the print to the beta... I'll wager that will keep your sync. If this doesn't help, might want to post this in the AJA KONA forum at http://www.creativecow.net Might be something to do with your LS, not sure but do have the latest drivers installed on it...

Video and audio sync is off

I have a video that was captured using the Hauppauge Win-TV 950Q and the Win TV software package. The file plays just fine in WinTV or using the Windows Media Player, but the timing of the audio and video seem to slip if I import it into Premiere Elements. I am using version 10, so I don't know if this is something that was fixed in a newer version. Over the course of an hour, the audio goes from off by about a second at the beginning to being something on the order of eight seconds behind at the end of an hour. Anyone know how to fix this?
Thanks
-Bob

thanks for looking! If I knew the answers to all your questions, I probably would know what's wrong and how to fix it. I am not looking to do anything exciting here, just trying to archive a program to a playable DVD. Well - I have it playable, it's just not watchable unless you can deal with badly synced audio.
Loaded up mediainfo and it says the frame rate is 29.97, but a variable bit rate for video and constant audio.
I will look into handbrake.
Oh - and Win 7 OS...
It's probably more than necessary - but here's the text output:

Getting The Video and Audio Synced Up

I have a the weirdest feeling that the audio and video are not perfectly synced up. It may only be by a frame or two. In final cut pro, I can go frame by frame and hear where the audio should be and correct it. Can this be done in DVD studio pro? Is there any other way to check? It is nothing big, but I would really love some assurance that they are together. I have DVDSP 3.

DVD SP is not designed for that type of precise editing, just some general things, and you are better off doing all edits outside of DVD SP. Where are you seeing the synch problem?

Import video and audio sync

I switched from version to version 2014 cc premiere I have a folder structure of AVCHD resources and previously when I imported a video file is automatically associated the relative audio files. In the new version does not. Exist a setting to be activated? thanks

Video and audio not in sync. Other answers here do not help.

My audio and video are not in sync in many streams but some are OK.
I do not have any extensions, add-ons and I am using the default theme. I have disabled hardware acceleration. I am now running in Safe Mode and the problem persists.
The video and audio sync for the first few minutes and then they work their way futhter and further apart, usually several seconds out of sync. I don't think this particular situation has been covered in the other posts.

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Recording Video and Audio at Same time with simultaneous sync

I want to record a keyboard performance into garageband and at the same time record the playing of that performance with my video camera. Then I want to create a movie using the music from garageband and the video from the camera. I was thinking that if I can sync the video and audio when I'm recording the session, then that part is taken care of. Or, maybe this is easier than I think it is?
Is there a way to do this so that I can use the garageband record performance and have it synced to the video on the camera?
I don't want to use the audio from the video camera because the performance that is captured in Garageband will be much better and I can do editing of the individual notes in GB.
In the end, I just want to make a movie and/or podcast of the performance.
I'm a newbie regarding this, but I did search the forums and couldn't find anything specific. Mostly it was about importing video into GB3 and then syncing new audio. I'll basically have audio and video from the same performance in two separate locations and I want to bring them together perfectly in Garageband.
Thanks for any help you can provide.
Powerbook G4 - DVI Mac OS X (10.4.9)

Okay. I got the video and audio all together. I told you I'd link to it when it was up.
http://www.youtube.com/watch?v=FxssYpUNJm8
There's also a copy of it at http://www.myspace.com/bonjimmy/
And as a quick side comment, even though I uploaded the same video to both YouTube and MySpace, the MySpace version is much better. YouTube must do something to the video after it's uploaded.
What I learned doing this project:
I recorded the video first (which gave me the sequencing of the piano performance) and then I dubbed the audio in later. However, there wasn't a good way to sync the video and the prerecorded piano, so there are some spots where the dubbed audio vocal isn't accurate to the video. I'm not sure what the pros do for this. I was hoping I'd remember how I sang for the video but when a couple weeks go by before re-doing the audio, it's about impossible. I tried, though.
I remember working with an old 4-track and smpte to a sequencer a long time ago. With the way it is now, it's pretty cool that you can record digitally and mix and match and everything falls together perfectly as long as you have a place to match the video and the audio. It's pretty cool.
What else???
Does anyone have suggestions that would have made it better? Also, if you have suggestions on my performance or whatever, I'd love comments, but you can do that on the linked page.
Thanks again for all your help. (The point of the video is because I'm thinking about getting back out there and doing some more playing... I'm looking for a band or something else interesting...)

How to align or sync video and audio?

In Premiere 13, once I have added a video/audio clip and then either slow down the clip or add photos in between the clip causes the video and audio to be out of sync. How does one re-align or re-sync the clip once it has been edited? Thanks

mrsndmn
On what computer operating system is your Premiere Elements 13 running?
There are several ways to avoid disturbing an existing Timeline when you are adding to it.
1. Using what are called keyboard modifiers, such as Ctrl or Alt (Windows).
2. Grouping block of clips so that the clips move together
The following video tutorial is offered for informational and not promotional reasons
Premiere Elements: Arranging clips on the Timeline using modifier keys | lynda.com - YouTube
It uses a version of Premiere Elements earlier than 13, but the principles involved are the same.
The video and audio that are going out of sync.... are they linked or grouped before the addition to the existing Timeline?
After the fact, you will need to move the Timeline components back in place.
If the video and audio are not linked or group, you can
(a) highlight the clip, hold down the Alt key of the computer main
keyboard and tap the appropriate arrow key for a 1 frame per tap nudge of the clip.
(b) highlight the clip, hold down the Shift+Alt key of the computer main
keyboard and tap the appropriate arrow key for a 5 frames per tap nudge of the clip.
Please review and consider. If questions or need clarification on the above, please do not hesitate to ask.
Thank you.

Video and audio not in sync

Anybody else experiencing video & audio not in sync since upgrading to Lion? I have a MacBook Pro 15-inch, Early 2011 with
AMD Radeon HD 6490M 256 MB graphics. I mostly stream You Tube, Netflix, & news videos and occasionally watch movies I have in iTunes or on DVD, and since upgrading, I've seen out of sync video and audio in every one of these situations. Sometimes it starts out OK and then slowly deteriorates. Other times it just starts out that way and stays that way. Happens with all browsers as well as iTunes and DVD Player. Tried a few Google searches but haven't come across any postings reporting this with Lion, so I thought I would try here. Thanks for any confirmations and/or pointers to a solution if there is one.

Ahh...boom. I have it too. Forgot it was even there. I had it turned off back when running Snow Leopard since it was glitchy. Apparenty, I somehow reenabled it and wasn't even aware it was on since its volume was turned down. After disabling it, all video & audio appears to be in sync.
boom...the sound you'll hear as I nuke it from my system.
Thanks efrancis76 for figuring this out. Much appreciated!

Video and Audio not in sync after capture

Hi there,
This is probably a common problem, I have trawled the site but can't seem to find and explanation for it.
I'm capturing vide/audio into final cut pro from my SONY DVR. The video i have streaming into the sony DVR is from a small covert video device which records video/audio onto an SD card. SO I'm running that into the DVR and then DVR is outputting that as DV PAL firewire (uncontrollable device).
I'm capturing the 40 minutes of video as one clip, and when i drag it into the timeline the audio and video are WAY out of sync. Is there a simple reason for why this is happening?
It's almost as if not capturing it right.
I hope someone can help,
Thanks in advance.
Jamie McIntyre

It is interesting that you are having this problem. I recently purchased a brand new Mac Pro (a week ago) and I am using Premiere Pro and it is doing the exact same thing. I mean this video and audio is REALLy out of sync. I tried capturing an hour at a time, and 30 minutes at a time. Still, no luck. I was debating on getting Final Cut, but after reading this post I am rethinking not only Final Cut, but using Apple all together. Part of me thinks that it is not a Premiere or Final Cut problem but a Mac OS problem. But hey, what do I know. I only edit for a living.

My Video and Audio are not syncing up after importing

I am trying to edit a few Ipad Clips in premier pro. My video and audio are not syncing. They are .mov lower resolution from the ipad. The original audio is fine - but after I put in a sequence the audio is off a few seconds (ahead). I did not add any affects or change anything. Please advise?
Thanks for any help in advance.
Allison

Premiere does not work well with variable frame rate video which, I expect, the ipad produces, You might have to convert the footage before you import it into Premiere. Do a forum search for variable frame rate, there are a lot of posts.

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.

Syncing video and audio

I have been syncing video and audio into a sequence and using those sequences in a new master sequence. Is that the right way to do it? Is there a way to have the video and audio in a useable clip? I could not find this information in the manual, but if I missed it can someone refer me to the chapter that covers this topic.
Thank you

you can set in and out points for both the video and audio clips in either the viewer or in the browser, then select the two, right click - merge clips (or Modify/Merge Clips if you prefer the menu.)

N95 Recorded Video: Video and audio is out of sync

Audio and video is out of sync when I play videos recorded with N95 on my PC. If have used different PC applications to play the video, but all exhibit the same problem.
In the beginning of at video it seems that the audio is about 400milliseconds ahead of the video - you hear the sound first. The different in audio and video is not constant. In a long video (30-50minutes) it is quite unpretictable how video and audio is out of sync in the end.
To experience the problem yourself record a long video sequence with a N95.
1 .Record something where it is easy to see if video and audio is in sync.
2. Transfer the recording to a PC.
3. Play the recording using VLC (www.videolan.org)
Another way to experience the problem is to convert the recording to AVI format at play it in MediaPlayer or WindowsMovieMaker. To convert a N95 video recording to AVI format use Mp4Cam2Avi.
http://sourceforge.net/projects/mp4cam2avi/
The video recording settings I use on my N95 are:
Best Quality
No Video Stablisation
Firmware version 21.0.0.16.
I think the video quality of N95 recordings is quite good, so I would really like to be able to view and edit the recorded vidoes on my PC.

You can edit videos on your PC, just converting them to AVI then using any Video Editor on the PC.
Yes while editing separate the audio channel from the clip and reinsert at the begining of the clip. This will minimise sync issues.To get accurate sync increase the timeline so that you are able to the see audio squiggles as a waveform.

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.
