Audio and Video become increasingly out of sync when watching a movie.

When I watch a movie from my itunes folder (purchased) the audio and video become increasingly out of sync. It is like watching an old Godzilla movie. I am using itunes on a Dell XPS M1530 running windows 7. Does anyone have a solution to this? I am not sure if I have a hardware problem or a software problem.
Thanks,
J

TS1362 All of the movies I have rented or purchased from iTunes in the last 4 months fail to play properly. The audio and video are constantly out of sync. I have followed the iTunes suggestions to correct this, however nothing has worked. (Windows 8)

I am using a Dell inspiron 14z, with Windows 8, and before that a Dell with Windows XP. This is also happening on my iPad. For the last four months, none of the movies or television shows I have rented or purchased from iTunes have played properly. The audio and video are out of sync. I have tried the troubleshooting measures iTunes suggested, however nothing seems to work. I have read on the community that this has been a problem for users in the past, and have attempted to try some of the fixes individual users have suggested also. Again, nothing seems to work. At this point I am frustrated, as we purchase or rent almost exclusively from iTunes. I would appreciate a support-staff person response. Thank you so much.

this problem has been going on for windows users for over a year now.
Apple has no solution to this problem.

Audio and Video Slowly Drift out of Sync

Ok so I'm hoping someone can help us out here.
So we have a video that was recorded 20 years ago on VHS tape. We captured that footage using a converter into FCP 7 using the DV-NTSC Capture preset with 48khz for audio.
The sound on that tape is awful and thankfully, we had a cassette tape that recorded all the audio. We used another converter to record that into pro-tools and bounced it out of pro tools using 48khz preset. Its currently a AIFF file.
Once we brought the two together in FInal Cut Pro, it starts off in sync but slowly drifts out about half way though. Any idea?

Find two sync points - one near the beginning and one near the end - maybe a syllable of speech, where you can see the mouth movements?
Put separate markers on your video and audio at all four points. Adjust the speed of the audio until the markers align.
You can calculate the new speed you need if you measure the lengths on the timeline accurately, and get the markers to match within a frame - plenty good enough over the whole timeline.

TS2972 I have ATV2 and the correct version of ITunes yet when watching a movie from ITunes, ATV2 will drop it mid way through and then will claim home sharing is not activated in ITunes. Can anyone offer advice please?

yepp, I have done numerous tests today, skipped router and hard wired betwenn PC and appletv3. same problem.
same network, but from my laptop, works like a charm.. so its not reproducable on all machines.
this seems to be a itunes/bonjour problem, not ATV3 problem.

Audio and Photos are playing out of sync once burnt onto DVD.

Hiya, I've created a slideshow, with music in the background, and when playing it through in the preview mode it all works fine, and the songs start and end where I want them to and all the photos and video clips work. Once it's bunt onto a DVD and played, the audio seems to be running ahead of the photo slideshow and it ends up out of sync. I've tried playing the DVD on the computer and the DVD player. but it makes no difference. Please help!

Are you using transitions in the slideshow? Sometime they play with different timing in the preview mode than they do on a DVD. Try removing the transitions and see what happens.

I have a 2nd generation ATV and my audio and video is cutting out.

The problem is intermittent. Sometimes the picture continues and only the sound skips. Sometimes both the audio and video cut out and return a second or so later. This even happens on the menu screens where the video and/or sounds will "hiccup". This happens when playing internet conent (like from iCloud or iTunes radio) or when playing content resident on my home computer via home sharing. I've tried the setup at more than one house, on more than one Wifi network and hooked to more than one TV, but the problem still occurs. Can anyone offer suggestions for a solution?

Audio and video are not running in sync

I'm having a problem with the video and sound not running together. When it first happened as any movie or tv show ect. would play the audio and Video would get further and further off as it would play. I reset my iPad and I thought the problem was fixed. But now they just are off by half a second to a second. It doesn't keep getting further apart like before but just stays consistently off. Why is this and what can I do. I'm a apple nubie and just got my iPad a week ago. I don't want mess anything up any further by tinkering.

There's nothing you can do on your iPad to fix this. If it's an iTunes movie or TV show, just email them to see if you can re-download the movie, since you might have a bad download.

Sound out of sync when burning a movie on The Mac.

I'm buring an AVI. movie just by right clicking and selecting burn the file to disc option and when I play the DVD on a seperate DVD player afte about 5 miniutes of film the sound is seconds out of sync from the actual movie, can anyone advise me?
Thanks

The best solution would be to use a DV capture utility and then import the resulting file(s) into final cut.
Aplle itself offers capture utilities, which can be found in the Developer Firewire SDK:
http://docs.info.apple.com/article.html?artnum=305924
You need a free Developer account and to download the SDK there. After installation you will find a new folder on your harddrive called "Developer"
There are several capture utilities in the program section of the SDK. You want to use the one called "VirtualDV". It´s very simple, but powerful though. It does capture without sync loss, compared to capturing via the Quicktime framework, like Final Cut and iMovie do. It simply grabs the raw DV stream coming from the Firewire interface.
After the capturing you have a Quicktime readable raw DV file, which easily can be imported to be worked with in any DV capable software.

Voice recorded on Gb and video on DSLR out of sync.

I recorded a cooking demo on video and captured the voice on GB and the image on a Nikon HD Dslr 300s at 25 fps. ( video setting to PAL ) When I brought them into FCPX to edit the audio and visual are out of sync ie. after about 30 sec the audio is about a sec later than the image.

This happen sometimes because either the camera and mac are running at different clock cycles or problem when importing or exporting of the media . The only thing you can do about it now is adjust the speed of the audio or video. You can do a bunch of math to figure it out of trial and error with speed adjustment. Also short clips will be less of a problem so you may want to split clips up some.

Audio and Video call greyed out

Hi. I m using ichat (lion OS) in my mac mini. My problem is cant video call or even call anyone, but people can video call me. When other's call me, both video and audio works fine. But in my ichat all i see is greyed out audio or video call. Please help..

HI,
If your Video Menu says Video Chat Enabled and your View Menu says the Show Video Status is On and the Bandwidth is set to at least 500kbps then I cannot see why you cannot initiate Chats.
You should either be able to click a green video icon next to a Buddy or highlight them and then use the icons at the bottom of the list (Or right-click a Buddy and you the pop up menu or highlight and use the Buddies Menu)
(i.e. there are lots of ways to start a chat)
If the Buddy is greyed Out but still showing a Video icon (Also greyed out) then that Buddy has faulty login.
Dark text Buddies are ON line but greyed out Video icons are then Busy

Audio and Video sound cuts out when adjusting the volume whilst playing powerpoint presentations

I have just bought a new hp laptop and when running power point presentations with embedded media (for my job) I cannot adjust the volume of the sound when the audio or video file is playing. It simply cuts out and stops the video or sound from playing. I thought at first that this might be an Office 2010 issue but now it seems more likely to be a setting on the laptop. If anyone has any answers they would be much appreciated!! Many Thanks

I hear you on this. I just tested out the 3GS video for a concert where band mixed electronica and guitars.. boom boom satellites and I noticed when close to the speaker side of the stage the sound cut in/out. But when I moved farther away sound remained consistant.
What I may suggest is lowering the volume to mid range when closer to your sound source then
correct (if needed) using outside software.. iMovie Final Cut, etc..
Yes, I wasn't to please about losing sound on a what I recorded.. ~A~

How to set up recordings of audio and video so that they will sync

I'm editing footage of a dance concert that used CDs for some of the dances and a live pianist for the remainder. In addition to the audio captured by the camera, I have all the CDs that were used and an additional audio recording of the piano that sounds much better than what was captured by the camera. I would like to use to mix the audio from the camera with the audio from the CDs and the additional recording of the piano, but the sources won't sync properly, since the camera, the CD player, and the audio recorder all run at slightly different speeds. For example, if I zoom in and line up the CD audio with the camera audio at the beginning of a song that lasts 3:21, at the end of the song the CD audio is late by about 11 frames. That's enough that I can't use the camera audio as ambient sound, and enough that the dancers are noticeably ahead of the music (by 11 frames).
I know I could time-correct my sources so that they will sync, but I'm wondering how to avoid this problem in the future.
Thanks,
John Link

John,
On most professional recording or editing environments we try to run a sync signal to all the devices. Many of the audio recorders out there are not equipped to accept or send sync. For that matter, neither are the consumer and prosumer cameras. That's one of the many things dividing pro from non-pro.
Wild sync , just running at a true and constant speed, is a lot easier now than " in the day." but one still sees issues like you have when not running sync between devices.

Audio and video clip lengths differ in encore timeline

Hi
I have been working to build a BD-R H.263 ac3 disk. I used AME from within Premiere Pro to export the M4V and (at the same time) AC3, using the present defualt parameters-no tweaking of any setting. The clips appear to play great on encore's monitor--everything in sync.And on the burned BD-R
However, I am getting the black screen between clips in the timeline when played in the standalone BD player, or (when I had one clip to a timeline) in a playlist. a previous poster made note of different length audio and video clips. I zoomed on the timeline and lo and behold--the the audio and video clips are different lengths.
This is with the timeline fully expand--each division is a frame. Note that break between the two audio clips is offset from the break between the two video clips by two frames. This offset is after several clips. I could find no information on what the one frame crosshatching at the end of the leading clips means. Can anyone explain this cross hatching? What do I do about it? the image below is after the first clip in the timeline:
In this image, the offset is less than a full frame??????
I tried using the trim tools to bring these together-but, the trim tool only lets it jump a full frame and then only to a GOP boundary, which doesn't help because the boundaries are obviously different fro the video and audio track.
I want to emphasize that these assets were created from the Premiere CS4 timeline (which had no offset between audio and video) using the default H.263 and AC3 presets in AME and the same presets selected in Encore.
The offsets do not appear to cause the actual audio and video to go out of sync when I play the burned disk. But, I get the 1-2 second wait between menus and chapters, or with items in a playlist.
The audio offset suggests that the player may not know what to do when faced with a chapter point that is different on the audio and video tracks, although, I will note that encore snapped to the joints in the video track not the audio track.
You can see from this listing that several of the clips audio and video lengths that differ by one frame. By the end of the timeline, the cummulative offset is 3 seconds (48 minute timeline)
Can anyone shed any light on this? Thanks

I don't think that I had the same problem that you do, but I thought I'd throw in my two cents just in case it might help. Encore would not build the output; it said something like the inpoint and the length did not match the endpoint. Actually, I think this happened in several different situations. In one case I simply adjusted the audio and video tracks to match endpoints. In the other case I went back to Premier and found that in some cases where I had added transitions it had shifted the endpoints of the audio and video tracks so they did not match. I removed the transitions. It didn't matter that much to me since I'm doing this for personal use. Is it possible those crosshatched lines you're seeing are transitions?
I am using CS 3 and editing HD. I have had many problems with encore. I read in the form someplace that it had a hard time handling H.264 so I changed to MPEG-2 and that fixed one problem. In another case it couldn't find some files and I found some advice not to use HD or wide menus, so I switched to standard 4:3 menus and it worked.

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 when using quicktime conversion

hello,
i am editing a hdv project and want to export to quicktime. the client needs it in a specific size (700x394). they do not want the video in the file compressed, just the size of image. they are compressing the video through flash for the web. anyways, i used to just use quicktime conversion, custom size and use 700x394, but now when i do that the audio and video are sparadically out of sync in the product. the wierd thing is that the project plays fine in the timeline, but when i export the problem occours. i then, exported to a full res fcp movie and it is fine. then tired reexporting through qt pro to 700x394. when i did this their were no sync issues but the quality of the file was not so good, it look more pixely, certainly not as good as when i did it using quicktime conversion.
how can i export through fcp to get the 700x394 file? someone said 'use current settings' instead of using quicktime conversion? how do i do this? what do i need to do and what are my settings?
any help is appreciated. thanks a ton in advance.
cheers,
clay

What format are you converting the HDV to?
If it's animation, it is quite possible your computer can't pull the data rate. In this case it would be a processor / hard drive issue not an out of sync issue.
