Ipad audio and sound out of sync

For a few months my iPad's audio has been out of sync with videos as well as the sounds like the keyboard clicks. Sometimes it is more out of sync, sometimes less. I have tried turning the device off and on again, resetting preferences, and searching online with no solutions found. Anyone know how I can fix this?

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.
I'm going to try to transfer several alternative video formats (video from my cable DVR, Video from live TV, and video from a digital mini cassette to try and figure out whether the VHS format is the culprit. Will keep you posted.

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.

Audio and video out of sync on short recordings

I've scanned the discussions and see that alot of posters are experiencing
the same problem I'm having which is recording quicktime movies
and getting audio and video out of sync.
In most of those posts the responses seem to be that the problem gets
bad if you're making a long recording. I'm experiencing that, but...
...I'm also having the same problem on really short recordings...less than a
minute. I've coming video and audio out of my cable box, into a SONY DSR-11 VCR, then firewire out of the deck into the computer, recording the movies with Quicktime 7.1.6.
I know it's coming out of the cable box and then out of the SONY deck via firewire in sync because when I log and capture through Final Cut Pro, audio and video are in sync in preview and playback. I don't want to use Final Cut Pro to capture the movies because I want to end up with MPEG4, and I'd have to go through an extra conversion process out of FCP.
Any thoughts on why even short recordings through Quicktime are out of sync?
Thanks.

I'm having similar problems transferring VHS video to Quicktime. Another problem I'm having is when I transfer a VHS video to iMovie and then export the video to H.264 format, I have similar sync problems, even though the iMovie seems perfectly in sync.

Flash player audio and vidio out of sync

flash player audio and vidio out of sync. audio lags 2 seconds behind vidio. this is a flash player or silverlighr problem. please help.

A lot of times it's in the video itself. A great example of it is "Tarantula", a 1955 "B" horror movie, on YouTube. About twenty minutes inti the film the audio suddenly drops about eight seconds behind the video. This happens when a video converter (software) requires more processor or RAM than the system converting it has available.
If it only happens with certain videos, it' what I've described above and there's really nothing that can be done about it.
If it happens with ALL videos you're watching, try right clicking, choosing "Settings", and under the far left tab, "Enable hardware acceleration"

Audio and video out of sync

I have captured tapes from my DVD camera and am in the process of editing clips and have noticed that the video and the audio are slightly out of sync.
How can I correct this?

I don't think it was a "DVD" camera!
Often sync problems are caused by recording the audio at a different setting than the Easy Setup capture preset.
The normal DV-PAL or NTSC Easy Setup is for 16bit audio.
If you recorded at 12 bit you need the "DV-PAL (or NTSC) 32KHz" Easy Setup.

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

Audio and Video out of sync in shared iMovie file

Hey Guys -
Quick question, I've created a new trailer in iMovie, all works fine but the audio and video is out of sync in the shared file. How to fix it?

Compressor audio and video out of sync

I've edited DV video in FCPX (where audio and video are in sync), sent to Compressor, and added the Dolby and MPEG-2 settings to my submitted job. But when I add the output files to Toast, the audio and video are not in sync. Reviewing the video in Compressor, it appears they are out of sync there as well (though it's hard to tell due to the choppiness of the playback there).
Any idea why this is occurring?

Try filling each gap in the audio timeline AND / OR set your encoding to CBR (Constant Bit Rate), not VBR. In some cases the DECODING part tries to fill gaps by "pulling" the next part of the audio if the stream has been encoded with VBR. Good luck.

TA25603 Audio and visual out of sync iMovie using built in mac webcam?

On the latest imovie - april 2013, I have made many videos and had no problems, but recently I've been using the macs inbuilt webcam and a couple of times when I re-watch the footage the audio is badly out of sync with the visual, how can I fix this?

Same issue I've seen. I have a Sony DCR-TRV30. Had 40 tapes to transfer to iMovie 10.0.6. Had no issue on first 16 tapes then all the sudden I experienced the audio/video timing issue. Video looks good when it is getting imported, audio/video in sync on camera and in preview window on iMovie while importing. Tape finishes and you start to watch import when beginning of tape is in sync and by end it is several seconds out of sync. Tried deleting and installing iMovie again and that didn't help.

QT breaking up and sound out of sync - cpu or ram or browser problem?

1. I try to watch BBC news video clips but can never get anything other than the sound out of sync, the picture breaking up and what I can only try to describe as a 'delayed streaming problem' where the film jumps frames from one frame to 'much later'.
2. Also the BBC has options of 'screen size' - I can't go to their large size so am stuck with a small version. (I don't think this is associated with the core problem.)
I play these clips either through Media Player or Real Player but it makes no difference.
I have flip4mac installed. I have the ATI display drivers updated.
I hope you understand the problem.
I hope I'll understand the answers!
Thanks for any helps.
Gordon

Another thing I've just noticed is that when the news clips are downloading and playing it is only at 36kbps. I have as far as I can set preferences at 256kbps.
I am connected to DSL but I'm not sure at what rate the ISP delivers. (I know it's the cheapest!)
Hope this helps anyone inclined to help.
Thanks

Audio and video out of sync on capture

I have been using the Canon HV20 and MacBook Pro for about a year now with no problems and for the first time today on capture the audio and video are out of sync. I have been using an external LaCie for capture and stoage but even using the internal HD, the same problem is occurring. I checked my preferences in FCE and used the disc utility to make sure my HD had no permission problems. I am not dropping any frames on capture. What do I do next to correct?

Hi - Thanks for you response.
It's a Canon XH A1 which is an HDV camera. As far as output is concerned when I play the camera it says HDV 24 and the sound is 16KB.

DVCPRO HD timecode - audio and video out of sync

I'm hoping this will turn out to be a "d'oh!" moment, but...
I'm working on a project which is being shot on the HVX200, with audio captured separately. The video is transferred to me via a FireStore, and I import both the video and separate audio (which is recorded to four .wav files) using the 'Import' command. Both video and audio are captured using free run timecode.
When imported, the video and audio have wildly different timecodes. For example, the video clip whose timecode starts 08:47:39:02 has a matching audio clip starting at 13:39:36:09. What's more, several of the video clips have the same timecode, even though they're different clips!
I've been through my settings and can find nothing obvious that I've done wrong. It's possible that the DoP and sound recordist have incorrectly synched their timecodes, but unlikely. Can anyone please think of anything that I could be doing differently which would solve the synching problem, or do I have to go back to the other guys and tell them the problem's probably with them?

Sounds like something that has to be done on set, then.
The audio's not being captured by the HVX200, perhaps I didn't make that clear; it's going to a separate hard drive. However, the HVX200 IS recording some audio using the on-board mic for reference, which is the only way I have any chance of synching the audio and video.
While in conversation with the DoP I notice that the filename for each video clip does contain what appears to be a date and time. This makes it possible to match each video clip with the relevant audio clip. However, this still makes it hard for me to do a frame-perfect sync as the timecodes are still radically different.
Anyway, the DoP who owns the FireStore is going to go away and look at it, so I'll let you know what he comes up with.

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 Pro Res export

I´m getting an audio/video sync issue when I´m exporting to Pro Res.
I started off in a HDV1080i50 sequence. Audio sampling rate is 48khz. (16 bit depth)
The sequence is less than 20 minutes long. It plays correctly on the timeline.
When I export the sequence for DVD and view it on a set top it plays absolutely fine.
When I export the video to ProRes (422 HQ - I used Export using Quicktime Conversion) and the audio to AIFF, they quickly go out of sync. This was brought to my attention first by the guys who were making the DigiBeta master, and when I view the exported material in a Pro Res sequence I can see it for myself.
The audio and video clips are of the exact same duration.
Possible issues...
Some of the narration was recorded at 44.1 khz. I didn´t resample it (I´m still a learning novice..).. but if that is the issue should it not have affected the DVD as well? All the other audio in the project is 48khz.
Most of the material is HDV1080i50..but one clip used was originally an NTSC clip and therefore a different frame rate. However I converted it to a 25fps clip and this is reflected in the vid rate column in the browser where it says 25fps.
Final point, the exported AIFF files..when I import them back into the HDV1080i50 sequence and play back, it is perfectly in sync.
Any help would be greatly appreciated.

First, yes resample the narration to 48k 16 bit. You will probably be able to reconnect to the resampled files. Usually works for me. That's a simple fix and will probably solve the problem. If it doesn't, you can try to change the codec (compressor) in the sequence settings to prores 422HQ, fully render and see if that solves the problem.
Wait, just reread your original post. Export from fcp using file: export: quicktime movie NOT quicktime conversion with current settings. If that works without synch issues, use compressor to convert to prores.
