Audio/video out of sync on 'video' app

Hi all,
I own an ipad 2 (iOS 5.1) and have purchased video content from iTunes. I've downloaded the content to my ipad and played the content via the pre-installed 'video' app but the audio is out of sync by about half a second.
I have tried restarting the ipad and re-downloading/downloading other titles but the audio is still out of sync.
Does anyone have a solution to fix this?
Thanks in anticipation!

This is a software issue..... do you have a bluetooth headphone? If so, try watching a video with it and you'll see it better in sync. iPad delays the audio to make up for the bluetooth normal delay of (150ms?)..... it seems that when you're not using a bluetooth device, it still delays the audio by that amount.

Teouble with audio becoming out of synce with video.

Hello, I'm using final cut to edit my videos but for some reason, FCP has been giving me some issues. In my work flow I often layout two long video track in the timeline, then I will chop up the top track to create transitions from the top to the bottom and vise versa. as soon I press play, it the video will start off in a slower speed almost as if the computer is overloaded, then it catches up to normal speed in about a second. This has really been driving my crazy. It also effects the way video syncronizes with audio. I can lay both video tracks on top of one another perfectly in sync with the audio, but as sometime once it get's to new scene or the video switches to another track the audio is no longer in sync with the video. sometimes I can stop the footage, then press space bar to copntine and the audio and video will be in sync. This is really weird and I was wondering if anyone has any answers for me. I'm pretty sure it's not an overload on the system because the projects are rather small, and I'm using a quad core 2.5, with 5 gig of ram. and this is my graphic card info

Thanks so much for you time.

Yes. Those that are designed to work with A/V files will work better.
Drives from G-tech and Granite Digital are worth a very close look.
However, if you have an empty drive bay in your G5, a second internal SATA drive is the better choice.
good luck.

Clip audio is out of sync with video

After analyzing the clip the code tells the tale. The audio is "shorter by 1 1/2 seconds yet the time line doesn't reflect it. I want to fix the problem but the tool I found requires the clip (red rectangular box with the +/- info.) to option/click on to be given the re-sync tool action. Other solutions require complicated solutions. My question is "What happened to cause this sync problem and how can I avoid it in the future. ie: no evidence of =/- red boxes to show that there is a problem even thought it clear when you look at the video clip ?

We are missing fundamental information:
What codec does your source footage use?
What is the audio sampling rate on the source footage?
What are the Sequence settings in FCP and does what you see there differ in any way to the properties of the source footage?
Version of Mac OS X, FCP and QuickTime?
Also; if you have a 2 x 3 GHz Dual-Core Intel Xeon Mac OS X 10.6.6, it's a Mac Pro, not a G5.

Captured content: Audio is out of sync from video

When I capture video off my Panasonic AG-DV2500 into FCP 5, the audio is around 17 frames behind. Does anyone have some advise for this problem?
G5 Tower Mac OS X (10.4.8)

It's not in the monitor. In recent projects, I've corrected the audio by 17 frames, and the final export does not reveal anything different. Good thought though.

Audio is out of sync with video

I have a project that includes still photos, video clips and background music. I did all the basic stuff (clip trimmer to mark the beats, aligned the photos/videos to the beats, etc.). It all works well except there's a glitch in the transition between two of the videos.
At the end of the first clip, there's a short segment (1-2 seconds) where the first clip turns into a still and the audio from the second clip starts while the first clip is still displayed. Throughout the second clip, the audio is off. If I start playing from the second clip, the audio is in synch.

Audio drifts out of sync with video

Hello --
I just watched the pilot for Conviction in iTunes on my PowerBook. The audio was just fine at the beginning, but by the end of the episode the audio was about 2 seconds behind the video. Everything on my system is up to date (OS, iTunes, Quicktime). Are others experienceing this and can it be corrected. I tried just pausing the video and restarting it but that did not correct the problem.
HELP! (and thanks)
-- Steven

so new versions of iTunes have seemed to correct this problem.

Video and audio goes out of sync when imported into Premiere

I have some videos ripped from some DVD that an acquaintance made, with an open source program called HandBrake, with the default "high profile" settings. When I play it both in VLC and in Quicktime, it plays just fine, but when I import it either in Premiere or in After effects, the video and audio goes out of sync (the video ran faster than the audio and when the video stops, the missing audio is trimmed).
Video info according to Premiere (in Spanish but you may get the meaning).

"HandBrake, these days, is almost entirely about H.264 video, aka MPEG-4 Part 10. HandBrake is migrating to quality-based encoding."
Hmmm. I use HC Encoder to make my DVDs because it's the only free encoder I've found with the much more professional Constant Q encoding option. But HC Encoder doesn't do HD sources for Blu-ray, so I've been wondering if I'd be stuck with the lame-*** consumer CBR and VBR options most encoders provide (including Adobe - hint, hint) when I eventually start working in HD. This is a very interesting program, Handbrake. I will have to check it out.

IMovie: I uploaded HDV video from a Canon HV20 and then to YouTube. The video and the audio are out of sync. The audio seems to precede the video by a tiny bit which is disconcerting. Any recommendations about how to correct this? Thank you.

I downloaded video via iMovie from my Canon HV20. The video was in HDV. I then published it to YouTube and Vimeo and in both cases, the audio is out of sync: the video precedes the audio by a fraction of a second. The original is fine as viewed in the camera.
Any suggestions as to why and how to correct it?
Thank you,
David

Anything here help?

Audio Tracks and Video Out of Sync!!

I am having a problem with not only the video and audio being out of sync, but the audio tracks, left and right, are out of sync with each other. I know it isn't the camera or tape because I watch the footage while it's capturing and it is fine, plus it happens all the time, with different tapes and different cameras. What would cause this and how do I fix it? Also, how do I set my preferences to automatically start the camera when I click capture? I have it set on my iMac but I can't find it on my G5.

Audio/video out of sync (audio delay) with PowerBeats wireless earphones.

I am having a problem with audio/video sync between my PowerBeats Wireless earphones with my MacPro and MacBookPro. I have tried pairing, playing the video, pausing the video, turning off the PowerBeats, tuning the PowerBeats on, then starting the video playback again. I have the same audio delay so this not working for me. Anyone have an update as to how to fix this audio/video sync problem?

I am playing MPEG-4 movie files. I did open MPlayerX from my dock, then pulled down File to select Open which then did show the folder where these movie files are stored. Then I was able to select a movie file, open it, and use "Decrease Audio Delay" to closely sync the audio with the video. I say closely because it is not perfect. Rather than stepping each increase or decrease in one tenth of a second, perhaps a finer adjustment would have been in milliseconds. This is the adjustment that I have with my AVR to sync the audio with the video, so I know this is a possible increment adjustment. The perfect adjustment was in between -0.4 and -0.5 second,however, this was not possible in one tenth second adjustments. The closest adjustment was with -0.4 second rather than with -0.5 second. So, adjustments in milliseconds could have been very near a perfect sync. Perhaps later versions of MPlayer will offer the adjustment selection in milliseconds. Nevertheless, this is working much, much better than before. Thank you so much. I have spent most of this day researching this problem and you have come up with by far the best solution. This problem goes all the way back to 2010 and possibly beyond for Apple products. There are hundreds of reports documenting out of sync audio/video issues with no solution that works as well as MPlayerX. Even the Beats support staff have no idea of how to resolve the audio/video out of sync.

Audio And Video out of sync in Final Cut, but not in quicktime

I heave searched the forums to no end to find the solution to this issue, unfortunatley, I have not solved the problem.
I am using Final Cut 4.5 on a G4 running OSX 10.3.4. This system has worked perfectly for years with no problems. Neither the system, hardware, or software has ever been changed on this machine. Suddenly last week, despite perfect sync while previewing the capture, the Audio and Video were of sync in Final Cut, but when checked in quicktime, there were no problems. That is how I eventually figured out this was a final cut problem.
By out of sync, I don't mean it is by a specific number of frames that can be adjusted and then everything is fine, the sync seems to drift so that if you edit the audio to be in sync in one part of the video, it won't be at the end. Also, it is out of sync from the first frame played, not a gradual drift.
This is definitely not an issue of frame rates or final cut settings as will be evident by the steps I took below to find the source of this problem.
This is what I did to attempt to fix the problem:
- Check drives using disc utility and repair permissions
- Remove Final Cut Preferences using Apple guidelines
- Switch hard drives
- Delete Final Cut and reinstall newer version of final cut (since the capture files played fine on Final Cut 5.1 on another machine)
- reinstall entire OSX 10.3.9, wiping the hard drive and reinstalling Final Cut 5.1
- switch ram slots, and even replace ram with different sticks from another G4 machine
None of these solutions worked. Is there some hardware problem with my G4 that is suddenly causing Final Cut to play audio and video out of sync?
Hope you can help, otherwise this otherwise great G4 is going in the dumpster!
Thanks

For what it's worth, I'm having what looks to be the same problem. Driving me insane. Here's what's going on-
Editing in FCP 6.0.2
QT was just updated to 7.3.1 the other day (hmm)
On an MacBookPro machine, OS 10.5.1
Software updater says everything's up to date of course.
DV-NTSC 24p (23.98) Advanced Pulldown Removal (footage was shot at 24PA on a DVX100b)
In Quicktime, the file previews fine, everything's in sync, everyone's happy. In FCP, the video and audio are wildly out of sync. I did a test inside of quicktime and sliced out a small portion of the media clip and did a "save as" and this small slice played in sync in FCP. However, this did not work for the entire clip. Clip is weighing in at 5.58GB for a 32 minute run.
I'm trying to multicam 2 tapes together and manually syncing these up is proving to be difficult at best. When anyone gets any ideas/leads/patches, let us know.
Grr,

Audio video out of sync?

Every movie I have rented and purchased the audio is out of sync with the video. If I pause the movie sometimes it goes back into sync but doesn't last long before it goes out of sync again. I have been trying to resolve this issue for the past week. I have turned off everything on the computer that manages audio, made sure all drivers and software is up to date. I have uninstalled itunes and reinstalled. I've set itunes and windows bit rate the exact same and nothing seems to fix the problem. I am running Windows 8 on a new Samsung laptop, previously I was using a Gateway laptop with no problems. From my reasearch the past couple days i see this has been on on going problem with itunes users and I hope someone has a fix. I just rented a movie from Xbox Video and it worked perfectly. I think I am going to have to make the switch to Xbox but I have movies I have downloaded to itunes and would like to watch them.
Any help would be appreicated.

Hello bjwilson22,
I was researching the symptom you describe and reocmmend this article named Troubleshooting iTunes for Windows Vista or Windows 7 video playback performance issues found here http://support.apple.com/kb/ts1718
It is pretty length, but also thorough and I feel has the best advice to help troubleshoot the issue.
All the very best,

Audio and Video out of Sync in Encore 2.0

Here's my issue:
I opened a project in Encore 2.0 that was an Encore 1.5 project. I have one timeline with a 2 hour movie and the AC3 audio file that goes with it. Encore 1.5 played the audio and video in sync from the timeline and burned discs with the audio in sync. The video is an MPEG2 file encoded at a 3.1 constant bit rate.
In Encore 2.0, when I play the timeline, the audio becomes progressively out of sync as it plays. Within the first few minutes it's maybe a frame or 2 off. By the end of the film it is about 18 seconds off (audio is playing ahead of the video).
Is this a result of Encore 2.0 conforming the audio file? If so, how am I (or anyone) supposed to attain sync between video and audio in Encore 2.0?
I have Encore 1.5 and 2.0 both installed on the same machine. As a test, I opened the project in 1.5 and played it, everything was fine. I closed Encore 1.5 and opened the project in Encore 2.0, and the audio is out of sync.
Any comments, ideas or suggestions?
Mike

Joe,
I tried creating a project with the original WAV file and it's corresponding video and found that the audio and video were still out of sync. I did a little more testing and discovered that the audio is actually being played correctly, it's the video that is not being played correctly. Here's what I did:
I opened the WAV file version of the audio file in Premiere Pro and noted where a hammer hit in the video occurs (01;40;30;28). I then opened Encore 2.0 and imported the video and AC3 version of the WAV file, placed them in a timeline and the audio's hammer hit is right where it's supposed to be (01;40;30;28), but the video's hammer hit occurs at 01;40;43;18.
Next I went into Encore 1.5 and brought in the AC3 audio and video files and placed them on a timeline. I went to 01;40;30;28 in the timeline and the audio and video were both at the frame they should be at that timecode.
Seeing how the video appears to be playing incorrectly, here's some info on my video files:
I have 4 versions of the same film in varying encode rates with the same start and end timecodes. All four files were encoded on a Sonic DVD Creator authoring station using hardware to encode. The files are encoded at the following rates: 2.9 constant bit rate, 3.1 constant bit rate, 3.4 variable bit rate and 4.0 variable bit rate. They are each NTSC with drop frame timecode. All four files play correctly in Encore 1.5 but incorrectly in Encore 2.0.
This almost seems like a drop frame/non-drop frame issue. Do you have any ideas?
Mike

In all your information, I did not see what computer operating system your Premiere Elements 12 is running on? Have you updated 12 to the 12.1 Update, using an opened project's Help Menu/Update? If not, please do so.
Your issue may relate to the details of your "VOB file" and how it was ripped/copied from the DVD-VIDEO and DVD disc to get it into a Premiere Elements project.
a. project preset set for NTSC DV Standard or NTSC DV Widescreen (whichever corresponded to your recording details)...or PAL equivalent.
b. DVD disc in burner tray
c. Add Media/DVD camera or computer drive/Video Importer/.....
It does not happened often, but if audio is out of sync and you are not using the above route, then consider the Command Prompt way described in the
following
ATR Premiere Elements Troubleshooting: PE: DVD-VIDEO/Seamless VOB Ripping
A just in case note, contrary to some, it is not necessary to convert VOB (VTS_01_1.VOB video file and any files in that series) to any other format in Premiere Elements.
Please review and consider and then we can decide what next.
Thank you.

Audio and video out of sync after exporting sequence

I'm a FCP user since years, but not so common with HD footage. Therefore I have an issue with my finished edited movie after exporting: Video and Audio are out of sync.
My sequence settings are: HDV1080i50, 25fps, 48kHz, 16bit, Stereo. I used File-> Export-> Quicktime Movie -> Current Settings
Sequence has a duration of 61 minutes and 38 sec. I tried to find out where's the problem and exported audio and video seperated. This results in:
Video is 61 minutes and 27 sec long
Audio is 61 minutes and 38 sec long
That means exported video is shorter than original sequence.
What could that be ?

I had the same problem with a Panasonic camera, even filming at 30 fps. I was able to fix it; see [this thread|http://discussions.apple.com/thread.jspa?threadID=1783029&tstart=0]. It's a frustating problem, to be sure. You might have to use Easy Setup a couple times before you get things to work properly. Not sure why that's the case.
Good luck!
