Audio Video sync off while playing DVDs

I recently installed Arch and when I play dvds using xine the a/v sync is off a bit so that the lips don't sync up. When playing a media file off my hdd the sync is perfect.
I am comming from slackware and using the same kernel (2.6.16.16) I used before, except changing the processor type to match arch's architecture, so I know that it works. In slackware I never had this problem but I was using xine-lib 1.1.1 instead of 1.1.2. I am also using xine-ui same as before. I have dma enabled on my dvd rom drive.
Am I just missing something?

Hi Joe,
Open Console in Utilities & see if there are any clues or repeating messages when this happens.

IDVD 08 audio/video sync drift toward end of DVD movie - fix/workaround?

Anyone know how I can fix this issue? It's driving me crazy.
I've just spent a few evenings in iMovie 08, editing together the video of my son's birth. All looked & amazingly good in iMovie. The "Large" .m4v file output by iMovie - Shared with the Media Browser - plays perfectly in Quicktime too.
However, after adding that shared movie to iDVD 08, and burning a DVD, I noticed that the audio sync drifts toward the end of the Movie when plated back. At the start of the DVD all seems well, but by the end of the ~1hr 20 minute movie the audio is unbearably out of sync with the video. Completely unwatchable.
After a little Googling I came across some reports that iDVD might not deal well with video that's been recorded with 12-bit audio. I've confirmed that my camcorder is (was!) set to 12-bit rather than 16-bit (the default, I'm sure). So if that's the problem I'm hosed... it's not like I can get a retake on that footage
Is there a reasonable workaround for this issue? I'm obviously unable to re-take the video (or the other 10 hours of DV video tape I've yet to use in an iMovie project). Ideally I'd like Apple to release a patch for this. Shouldn't it be possible for iDVD to account for audio that was originally recorded in 12-bit... even if it's just a checkbox you have to select to tip it off?
Then again, perhaps this is totally unrelated to the 12-bit issue, and this is just a run of the mill bug?
As I said... iMovie generates a MPEG4 video file of the Movie that looks/sounds perfect, so it seems this sync issue's being created somewhere in iDVD as it's rendering the audio/video to burn to the DVD...
Thanks in advance.

I've tried most of the options I can think of, and the audio sync drift issue continues on this ~1hr 12 minute iMovie/iDVD 08 project.
A couple of promising ideas tried used QT Pro, to export the audio track from the iMovie generated MPEG-4 file - as a WAV file, resampling to 48kHz and 16-bit... then Adding this back to the video track in the MPEG-4 file (having deleted the original audio track). In another test I also tried the Add to Selection and Scale option. Oddly enough I think the Add to Selection and Scale attempt generated more sync issues than before in the final DVD movie... so I stuck with the MPEG-4 file containing the video track and the added, resampled at 48kHz & 16 bit, WAV audio track.
This was saved as a self contained Movie file, producing a QT .mov file. I moved this .mov file into the iDVD projects directory structure so that it was avalable in iDVD's Media Browser. I then reworked the iDVD project to use this QT large.mov file, instead of the original iMovie large.m4v file.
As a reminder... the original large.m4v file has the following properties:
29.97 FPS H.264 Decoder, 960 x 540, Millions
AAC, Stereo (L R), 44.100 kHz
0:01:12:07.16 duration
The resampled and saved QT MOV file has the following properties:
29.97 FPS H.264 Decoder, 960 x 540, Millions
16-bit Integer (Little Endian), Stereo, 48.000 kHz
0:01:12:07.16 duration
BOTH versions of this Movie file play flawlessly within QT Pro... there's no audio sync drift evident toward the end of the movie unless I use iDVD 08 to burn either movie file to a Physical DVD (or DVD Disk Image). In both cases the resultant DVD Movie exhibits significant audio sync drift as the ~1hr 12 minute movie progresses. The sync goes out by ~ <= 1 second based on a rough visual assessment.
I've not yet tried to burn either the original iMovie produced MPEG-4 video file or my QT Pro tweaked audio track .MOV file version to a DVD on my PC...
... But I have used an application called Burn (referenced in this earlier/archived iDVD sync drift forum post: http://discussions.apple.com/thread.jspa?threadID=1332100 by user F Shippey - http://burn-osx.sourceforge.net/) to take the QT Pro tweaked .mov file version of the original MPEG-4 file and burn it to a DVD...
Results:
The Burn app burnt DVD plays with NO audio sync issues!... Even though it was generated from the same audio tweaked (48kHz/16-bit resampled) QT Pro .mov file.
However, whenever I burn a DVD using iDVD 08 the audio sync gradually drifts. It matters not whether I use the original iMovie 08 generated MPEG-4 movie file, or the QT Pro version of that file with the resampled audio track (the same one that works fine with Burn).
It sure looks to me like iDVD has a problem... Again, refer to http://discussions.apple.com/thread.jspa?threadID=1332100 for someone else who seems to have run into similar challenges.
Am I overlooking something?
Thanks in advance.

'Source play' and 'audio-video sync' problems with PE8 on fast WIN7 64 bit computer

I am transferring Hi8 videos, about 2 hours long, to my WIN7 64 bit computer with PE8. [Dell Mobile Precision M4400 Computer Workstation (Intel Core 2 Duo T9900 500GB/4GB); NVIDIA Quadro FX 770M, 512MB] I seem to have several problems:
First, after importing the file (.avi), I get a message about ‘dropped frames.’
Secondly, when I try to play the video in the source monitor, the audio plays but the video doesn’t; it only shows the first frame [this is after waiting until the video is ?recognized? ] I can use the shift-arrow key and see that the video is there.
Thirdly, I can play the .avi file in other players, e.g., avidemux or PE pro CS5 on another computer. There, I see that the audio and video are not in sync; the audio can be up to 300 ms ahead of the video (as determined using avidemux).
Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

"I think you're telling me you're using a backwards compatible Digital8 camcorder to capture your video as DV-AVIs. Is that right?" YES
"Are you using Premiere Elements to do this capturing?" YES, AS ABOVE PE8
"Go to the File menu and select Properties. It should show a standard DV codec being used for your video and audio."
WMP v12 is dumb. Under properties, media, it says 'video.' However, avidemux gave me the information state above: video -- Codec 4CC: dvsd, frame rate: 29.971 fps; audio -- codec: PCM, channels: Stereo, frequency: 48 kHz.
So, back to the Questions:
1. Why doesn’t the source monitor play the video? Is this a problem with PE8 (latest update as of 3 March 2011) on aWIN7 64 bit computer (intel duo core. 3 GHz).
2. Is the audio-video sync problem the result of the ‘dropped frames?’ How can PE8 correct this? Avoid this? Or, is it coincidence?

S890 screen turns off while playing games

I bought this phone a week ago.Everything about this phone is awesom except one thing. The screen turns off while playing games automatically,which is really annoying. Is there any fix for this??

Graphics card springs to mind;
also, in your game settings, in either options or video settings (or similar). Are the settings correct for your card. I know on a low end PC, "full hardware acceleration" can cause crashing.
I'd still think, it's more a graphics related problem. If you have a big flat screen mintor (e.g 24,27 or even 30") then that, in it's own right needs a good card. Add the game to it and you may have problems. I do take it you have compared the specs with what's required on the box (of the game) and "about this mac/"more info"). All the best.

Regular problem with video playback & audio video sync

So, I am regularly having two problems (I wonder whether they are connected) that I cannot solve and am hoping someone can tell me if I am out of luck or if I need to do something or add something.
For example, because it happened again today. These are details about the file stuff:
Type:AVI
Bit Rate:133kbps
Dimensions:624x352
Audio format: LameMP3
Frame rate: 23 frames/second
Data Rate: 1131 kbps
Video Sample Size: 12 bit
Video Compression: XVID
First Problem: If I play the file - I use Media Player Classic - it plays fine. Open it in Windows Media Player and it plays fine. Try to edit it in Premiere and the file loaded into Premiere is filled with what I believe are called audio video sync problems, so I have to constantly unlink audio and video and adjust it. It loads and does not need to conform.
I have the same problem on my laptop(Windows XP Home) and desktop (XP Pro), the desktop with twice the RAM. I have the K-lite Mega codec pack installed. I would call myself a beginner when it comes to video editing. I understand generally what codecs are but I am not capable to making any tweaks to the K-lite Mega codec pack (if I should have) so it is setup as installed.
Second Problem: The video in the playback box never plays back normally. I have tried adjusting the playback settings: have changed the aspect ratio between the software and harware option and adjusted between the three desktop display options. Occasionally it is "ok" but most of the time not and never just normal.
Any help is much appreciated.
Thank you.

I tried this already and then we had a blackout so going to try again and hope it goes through before a second one...lol
Hello:
Thank you Robert J. Johnston, the_wine_snob, Paul_LS and SteveGrisetti for your help so far.
So this is where I am at now:
Files all seem to be of the same type, so I will just say "the file" for the one I am working with right now.
Loaded file into VirtualDub. I like that program. Well done, whoever made it. Did some basic cutting of unwanted stuff. Saved as AVI. Saved both a Direct Stream Copy and a Full Processing Copy.
Opened the FP copy in Premiere Elements and it plays without audio sync problems that I can see. Have edited it some so far and still no problems.
Before I do any more editing work, I decided to save it (SHARE) in different formats to see what happens.
Goal: Looking for no audio sync problems. Best quality I can get with a 1GB file size limit.
Saved as DV-AVI: plays fine. no audio sync probelms. love the video quality. 2.95GB, so too big
Saved as Flash: Do not see any audio sync problems. Do NOT like the quality (flips back and forth between clear and all pixely (is that a word). 32 MG
Saved as Mpeg: Media Player won't play it (thought Media Player with KL Mega Codec played everything?) (It loads it but doesn't play?); Quicktime won't play it. Windows Media Player just did. Do not see any audio sync problems. Like the video quality. 631 MB.
Saved as Windows Media: Do not "think" there are any audio sync problems; if there are, they are very subtle. Not crazy about video quality. Better than flash video option though still flickers between two types of qaulity (if that makes sense) . 52MB
Any suggestions as to what I should do at this point to meet my stated goal. I assume [share]ing is what I should do? Is there any exporting or any other options I do not know about. Without your help I figure I will Share to MPEG? Not sure why Media Player won't play it and Windows Media Player will?
Any thoughts on the best choice for me? Thanks for your help.

Audio/Video sync drift in Premiere CS5.5, but not in CS6

I have a QuickTime file with the following specs:
Video: H.264, 854x480, 29.99fps
Audio: AAC, 44100 Hz
When I open the file in QT player, or in Adobe Premiere CS6, there is no issue with Audio/Video sync.
However, when I import the file in Premiere CS 5.5, there is a drift in the Audio/Video sync.
Is there something I can do in Premiere CS 5.5 to avoid or fix the drift?
Thanks.

I had a similar problem and these are the steps I took to fix it.
First I deleted the files in "Adobe Premiere Pro Preview Files" for the project in question. I reopened Premiere and it appeared that deleting those files didn't seem to do anything as everything in the project looked the same.
I then disconnected the drive with the footage on it and opened Premiere. When it asked where the footage was, I told it to Offline All. I then went into Preferences > Media and hit Clean for the Media Cache Database. This had to be done because it only cleans the cache for files that are no longer connected with the project (as noted above). I closed and reopened the project, selected everything in the Project window, right clicked and chose Relink Media. I located one file and it relinked the rest automatically.
Now, finally, Premiere is re-conforming all the audio. Hooray!

Audio/Video sync program for Power PC G5

Greetings to ALL, I am attempting to determine if there is a audio/video sync program for my PPC G5 running 10.5.8?
Suggestions would be great because if I cannot locate a program I am at the end of the road for this little project.
Working with a Nikon D7000 and RODE Pro Mic and looking to get the Tascam DR 100MkII recorder if I can figure out how to get things to jell.
Thank You, pc

Even if syncing directly is not practical, iTunes can manage audio files, has many organization features for audio, such as playlists and folders of playlist, and tags that can be applied to multiple audio and video files are supported by it. MPEG4Streamclip offfers a variety of conversion tools that are available for PowerPC for video and will bring videos to work with iTunes. H.264 MPEG4s are the best for iTunes.
And http://www.lemkesoft.com/ GraphicConverter lets you browse Finder folders, which you can tag by month, and year, and even time, in a hierarchy that makes sure you don't do any duplication. Since the Nikon D7000 does write to standard SD cards, you just need a Mac OS X 10.5 supporting SD card reader. Many SansDisk readers supports it.

BUG: Speed Change + Audio Transition = No Audio-Video Sync

BUG: Speed Change + Audio Transition = No Audio-Video Sync
If you change the speed of clips (125%) and make an audio transition between them (power), the audio runs out of sync. The longer the transition, the more out of sync.

Ipod cuts off while playing

Suddenly, my ipod within my iPhone cuts off while playing in the shuffle mode. Most times this occurs while I have it in my pocket and am moving, but I have no idea whether this matters or not. It will either cut off completely or skip to the next song after cutting off in the middle of the previous song. Is there something that I can do to fix this?

I have the same issue. The phone works fine if I am sitting around, no problems listening to hours of music. I ride my bike and have the phone in my jersey pocket and after about 15-30min it starts going into an auto pause mode to the point I can no longer listen. This is very annoying and I think it must have something to do with the motion sensing causing the pauses.

What would cause the original I Pad shut itself off while playing games or online? it is not a battery issue or time issue. When I turn it back on it goes to were I was when I was online ,but have to start games over.

The original iPad has a slow processor and only 256 MB of memory so it often runs into low-memory failures.
Double click the home button and dismiss all of the recents - I do that weekly.
Then reboot by holding both the power and home buttons until the apple logo appears, ignore the red slider - I also do that weekly.
Both seem to help to reduce the low-memory faults that occur.

Satellite 2430-S255 turns itself off while playing video clips

My Toshiba Notebook Satellite 2430-s255 turns itself off within 5 minutes whenever I play streaming video clips from web sites using Windows Media Player version 10.0. I uninstall version 10 and used version 9, but there was no difference. Computer has 512 meg memory and 10 gig of extra space on harddisk.
There is no problem when I play DVD using the same software.
Toshiba support has been telling me that cpu is working hard and it heats up to cause this problem. I used fan to circulate the air, but computer still turns itself off.
Can some one help.
Jyotsna

HI Jyotsna,
Any graphics activity will tend to make your notebook run hotter and will therefore need adequate cooling.
Check that your airways through the CPU heatsink are not clogged with dust and debris (lots of threads in this forum about it), and also make sure that there is sufficient air gap under your notebook to allow air to get in to the fan vents.

Lowering bitrate: will it cause loss of audio/video sync?

Hi I own both an ipad 2 and ipod touch 4g. A while back I converted some videos using handbrake and they all became off sync when I play in both ipod and ipad. The original bitrate is 10k ish since its DVD quality, and it was 30fps. I converted to about 5k bitrate @ 29.97fps H.264 format. I was wondering if it going off sync was because of the fps difference or lowering the bitrate?
Since alot of the vids I intend on putting on my ipad 2 are all DVD rips (higher sound quality), but the bitrate are always in the 9-12k range. I tried reconverting that DVD rip with 10k bitrate and itunes gave me a message saying it cannot be added onto ipad.
So I was wondering if theres a solution to this? I don't really want the resulting converted file to be too big (resulting file for a 3min video was 300MB+), but then I want to keep quality + sync. Is it possible to lower the bitrate without losing sync? The program I use are handbrake and formatfactory, both convert perfectly unless converting videos with really high bitrates.

You must mean when you are working in the Viewer, the sync is maintained.
If sync is lost, it is often the result of mismatched audio sample rates. For example, if your sequence is set to 48khz/16 bit and your clip is 32khz/12bit, audio can drift. It will drift even if the audio is 48.001khz.
Only DVCAM locks audio to video. Long captures using consumer equipment are particularly susceptible to drift. One strategy to avoid it is to log the clips on the tape and capture in short segments.
Good luck.

Sound drops while playing DVD

Hopefully I can describe this issue accurately enough for some assistance.
My MacMini is connected to a TV via DVI and a 3.5 audio connection. Recently, when watching DVDs through Front Row, I have been noticing audio dropout during loud scenes in movies. The sound does not go out totally it just reduces, almost like it looses stereo, then jumps back up to normal volume when the scene background noise decreases or stops.
I've also noticed that sometimes the sound is not perfectly synched with the video image, this is rare though and is so slight you can barley notice sometimes.
Any idea why this might be happening? Is there anything I can do with my system configuration to help this?

I'm sorry no-one has been able to help you. I'd say that was rare, but looking back at some of the other threads you've started I can see why you might conclude that Apple Discussions isn't much help!
While I can't help you directly because this is not a problem that is familiar to me, I use a Mac mini (older G4 model) to play TV content (Real media files) on a TV, and Front Row to access and play a ripped DVD library. I don't experience either sound dropout or audio-sync issues you describe, but it does make me wonder what type of files you're playing, and how (without going into details since discussion of ripping methodologies isn't allowed here) the DVD content is put on your system for replay. In other words, my first suspicion would be whether something in the ripping process is causing these problems.
Given that I can't offer a similar experience I realize this isn't all that helpful, but perhaps that might get the ball rolling - with luck!

Movies lose audio/video sync as they progress

I've got a lot of old VHS tapes I'm transferring to DVD-R. I play them on my VHS player connected to DAC-100 converter that goes into iMovie. From iMovie I burn the video either with Toast or iDVD. Either way, a lot of the DVD-R's have the audio out of sync with the video, and some don't! They are synced when I play them back in iMovie before burning.Sometimes the sync on the burnt DVD-R is ok at the beginning but slowing goes out of sync so by the end of the video it's way out of sync. So, what's one to do?? I hate to waste the time & discs but it seems there's no way to know for sure how a DVD-R's going to turn out until you burn it and play it.
And, while I'm at it, the latest version of iMovie HD makes the clips all about an hour long. I prefer them shorter(like in the older versions), but I can find no preference to set a length.
Help!

I have been bitten by the sync problem as well, and have spent most of this week trying to troubleshoot it. FYI, I've been doing video conversion and editing on PC's for years, but recently moved to OSX, a Datavideo DAC-100 (Firewire DV analog capture device) and the iLife tools.
And before anyone asks, I use 16 bit audio capture. I've verified this by looking at the file that are generated. I've also looked at all the iMovie sync FAQ's on the Internet. Audio sync problems and I are old enemies.
Here's what I've found:
While the video is in it's original DV file captured by iMovie, the audio sync is perfect. I've done a 3 hour capture, and the sync was fine all the way through.
When and where the sync goes bad is when the audio is extracted from the DV file, whether by manually extracting the audio in iMovie, converting the DV to another format (including another DV file), or 'sharing' the movie to iDVD. I belive this is because the DV file format tightly links the audio to the movie timeline. When the audio is extracted, it is associated to the video only by the length (in time) of the two files. And either the audio is slightly time compressed, or the video is slightly time expanded. I suspect the audio is slightly time compressed.
I've created a predictable test case with my video, where i can capture a 15 minute block of video. At the end of the file the audio sync is perfect while in the DV format , and is ahead of the video by about 1.5 seconds after extracted.
A simple workaround would be to use a sound or video editing package that allows you chop the audio when it goes silent and to stretch the remaining audio to match the length of the video. VirtualDub and CoolEdit for the PC used to be able to do this. I've tried doing this with Quicktime Pro with no success, though. I'll keep looking for a decent OSX program to try to do this with.
This does, however, only work around the problem, not identify where it is, or fix it.
I think I've also determined that this is a problem in the standard OSX DV stream capture API, not in the conversion process of Quicktime from DV audio to whatever.
I used BTV Pro (http://www.bensoftware.com/), a shareware/capture tool that can handle DV streams on my test case. The results were EXACTLY the same as under iMovie. I believe that BTV uses OSX's standard APIs for accessing DV streams from firewire.
Additionally, I've extracted the audio from the test DV using a non-apple DV codec (ffmpeg), and reimported it to iMovie and Quicktime. It is identical to the bad sync audio that iMovie extracts.
This leads me to believe that it's a problem with either the DAC-100's DV streams (which is set to the OSX dip switch settings) or OSX's DV capture API.
I then installed Avid Free DV (http://www.avid.com/freedv/index.asp), a free stripped down version of a high end OSX video editing package, and successfully captured the 15 minute test case, exported it to a DV file (using both the AVID and Apple DV codecs), imported the resulting DV file into iMovie, and extracted the audio. The extracted audio synced perfectly with the video in iMovie at this point.
Just to make sure that Avid didn't just 'fix' a bad DV file, I did another test capture from iMovie, and imported the file into Avid Free DV. The resulting video had the expected sync problem, which was expected since Avid uses Quicktime for importing and exporting video.
This points the problem squarely at the Apple capture APIs, as I believe that AVID uses its own. For some reason, the files generated by iMovie/BTV exhibit the sync problems when the audio is extracted in all cases, while files generated by Avid Free DV do not.
I still don't know what the issue is with OSX/iMovie and my DAC-100. I also know that not all DAC-100 users have the problem, nor do all iMovie users with their equipment. This could be a codec incompatibility with the version of firmware on the DAC-100 with OSX, a bug in the cap
