Sound and Video not sync

Hi I do have a Brand New Samsung PN51F5300 not smart TV hook it to a MC572LL/A Apple TV box, When I turn TV and Apple box after 30-40 minutes video is not syncronize with audio, video is faster, I've called Samsung and sent me a software update (thumb drive) on the mail and I have already updated and problem still remains I have tried hook the TV with another cable systems ( Comcast and Road runner) and and have not had any problems, I've tried to lower the resolution on the Apple TV box but th eonly option I do have is 720p, Tv is fine what can I do to resolve this issue, please help!!!!

I have the same tv and an Apple TV 3 (I dont recall if it is the original or Rev.A) and I get an audio lag through in-tv speakers. I use one HDMI cable for audio and video. I seem to notice it throughout and not just after 30 minutes. I can't figure out a work around. Although, I did purchase a home theater system so I will be using an AVR for audio soon.

[Python pygame] Graphic equalizer - keeping sound and video in sync

Hi!
I'm writing a graphic equalizer in python and I want to use pygame for the video and audio output.
The video display of the moving bars works great, now that I have a correct way to read samples and decode them.
The problem now is: they're way out of sync with the audio playing in the background!
At the moment my code, that draws the bars basically looks like this:
# loop as long as we can get slice of the audio file for the fft
for n_frame in range(0, len(framebuffer), fftframesz):
clock.tick_busy_loop(t_loop)
# t_loop was defined as fftframesz over total_frame_count
# which means in words: t_loop is the amount of FFTs per second - or the cycles of THIS loop
# grab the frames and perform the fft here
...numpy.fft.fft...
# set the new bar heights and draw them
for bar in bars:
bar.update()
# if playback has not started yet, make it so
if not pygame.mixer.get_busy():
musicfile.play()
The way I'm thinking, this should be enough to keep sound and video in sync. Because we know the time that one cycle should take at most,
we can set the clock to tick_busy_loop this time. This way we make sure that the video is not faster than the sound.
But to me it seems that is is the other way round, i.e. that the video is slower than the sound. I already did some timing, but to no avail.
Is there perhaps a more easy, more elegant way to make sure that image and audio are in sync?
Any help is greatly appreciated!

Thanks for your ideas. I assume you mean I should go with a $1200.00 final cut pro software. NOT.
Sure the video will be on myspace and youtube but wether they are noticed or not is not as important as self satisfaction. I can easily split scenes into equal time zones as I said. Then drag them into clips and back all using the same camcorder. Multiple cameras and angles would be nice but this can be done on a low budget and still look good. I guess my original questions were not answered. Is there a way to determine the length of a transition and shorten the clip by that amount. Or the length of a still shot and do the same. Or perhaps they have been answered and the answer is NO WAY, and I am just not hearing it.
I suppose reimporting a video would be great if I could use two timelines like in audio and then blank out what I don't want in the first. But I just don't think this is possible, or is it. I've been reading iMovie HD6 The Manual that should have been in the box. It's a help but doesn't take you from the beginning of a project to the final project. Exporting to imovie or idvd is not an issue. BTW I got the clips in sync as I said by leaving blank spots and placing effects over them. I could insert the proper length video in those spots but that can look silly without transitions. But then again so can transitions. This stuff is very fun and interesting and a great learning experience. If I stop now as you suggest then I am not pushing myself to the limit. But thanks for your reply.

Sound and Video not in sync

Dear Forum,
apologies if I happen to ask something already treated elsewhere (I searched and didn't find)!
I'm having the following problem with my 3rd gen Nano: in movies longer than around 20-25 min sound and image progressively get out of sync. The sound runs ahead of the picture - after around 45 min the shift can be several seconds. The video is encoded with EyeTV (the "iPod best" setting) in H.264 at 640x480, 25fps, around 1.6 Mbps. This should - according to the nano specs - be fine.
Has anyone else come across this?
Does anyone know of a fix?
Thanks very much!!

same issue here.

Audio and video not sync

Hi I'm having trouble with my records, i just shoot two videos for my vlogg and one was fine and the next one the audio is not sync with the video, didnt change any settings so dont understand wha happened. can some one help me fix this. thanks

Using the inbuilt camera on your MacBook Pro can result in audio not syncing with the video, due to the variable frame rate used by the camera.

Sound and videos not working

Hello,
I bought my HP laptop almost a year ago for my first year of university and recently the sound has been stopping and starting.
The sound sometimes works fine, but other times it works to begin with but then within the space of a few minutes it stops and won't work again until I shut my laptop off and turn it back on again.
When the sound won't work, neither will any youtube videos or iTunes songs, they stay on 00:00 and don't play at all.
I've tried all the help given on this link: http://h10025.www1.hp.com/ewfrf/wc/document?cc=uk&lc=en&docname=c03257712#N432 but to no help. My computer is all updated, the speakers say they have no new updates, and all my anti virus software says my computer is protected and under no threat.
When doing all the stages on the link above, the Step 2 'change stystem sounds' part says that 'the device is being used by another application' when checking each individual speaker, even though I have nothing else running. So I am a little confused at what else could be running.
I have read a few of the help posts given for this type of problem and apparently deleting the audio speakers from device manager hasn't been very helpful for some people and I am wary of deleting things and making matters worse.
If someone could please get back to me to help I'd appreciate it. If not I'll have to go into PC World to get it fixed, as my laptop is still under warranty and should not be having problems after less than a year of use.
Thanks

Hi,
Try the following.
Open windows Control Panel, open Windows Update, select 'View update history' in the left hand pane and then select 'Installed updates' link in the following window.
Locate update KB2962407, right click it and select Uninstall. When done, restart the notebook, open windows Control Panel, open Windows Update and select 'Check for updates'. You'll see the update you just uninstalled being offered again - right click and select 'Hide Update'.
After this you may or may not need to delete and reload the Audio driver - if you do, the procedure for using recovery manager to reinstall Software and Drivers is detailed in the document on the link below.
Recovery Manager - Windows 8.

Please help with audio and video not syncing.

I'm using Encore 3, and have already authored a DVD a month ago without a glitch. The following are the same steps I used, but this time around, the video and audio in Encore are not syncing.
Here's what I've done.
1) I export my Final Cut projects to .mov using the following settings (Share > Master File).
Format: Video and Audio
Video codec: H.264
Resolution: 1920x1080
Audio file format: Quicktime Movie (AAC)
Include chapter markers: Unchecked
Roles as: Quicktime Movie
2) I run the .mov file in Compressor using the "Disc Burning" preset.
3) I then import the .ac3 and .m2v files that Compressor created into Encore.
4) In Encore, I select both files and go to New > Timeline.
In the Timeline window, the durations on both are the same. But I don't understand why the audio and video are not synced when I preview or when I burn a test DVD. The audio comes in just a tad late.
Video Clip:
Source In: 00;00;00;00
Duration: 00;02;33;29
In-Point: 00;00;00;00
Out-Point: 00;02;33;29
Audio Clip:
Source In: 00;00;00;00
Duration: 00;02;34;00
In-Point: 00;00;00;00
Out-Point: 00;02;34;00
What's puzzling is that two of the 10 videos I've import to Encore are synced perfectly -- same export settings from FCP, same settings Compressor.
Please help.
Thanks!
Mark

Hi Mark.
Do you have any situations where there is more than one video file in a timeline?
Secondly - why are you using H264 HD files for a DVD? This is using lossy compression to make the H264, which is in turn then scaled & even further bitrate reduced for M2V.
I would give it a try rendering an SD video file for use in Encore - not the H264 - and starting out with Dolby Digital or LPCM audio, not AAC.
As with all DVD authoring programs, Encore works best with DVD compliant assets - which you are most definitely using - but I still think you are over-complicating things by using H264/AAC at all.
Eliminating this may help.

Photo Booth - audio and video not syncing

I was making some videos on Photo Booth and the audio doesn't start playing until 5 seconds after the video starts! Do you know if there is any way to fix this or is it a software issue? I have tried resetting the computer but it didn't help.
Thanks for your help!

In Photo Booth, right-click on the video and either Export or Reveal in Finder. Either way, then open and play it with QuickTime. Is audio and video still out of sync?

Audio and Video not syncing

I paid for a movie and I can't watch it on either iTunes or QuickTime and, yes, I tried most of those helps in that FAQ post. I say most because this is the most advanced comp money could buy so I do NOT need hardware OR software updates, seeing how I did the latter before finally giving in to ***** at you. Yes I am mad. I'm highly annoyed. I paid money I could ill afford to spend on a movie I really was looking forward to watching ("A Dog's Breakfast" starring David Hewlett) only to find that it won't play!
Or rather, it plays, but the video skips and is out of sync with the audio. The help files in the "support" tap and the "Help" sections of both programs have been supremely unhelpful. Either refund me my money, or tell me how to fix this so I can watch this. Why people say Macs and Apple are better than Windows, I'll never know. At least with Windows you know you'll get screwed over.
I realize this flame-ish piece has no made me popular and will likely be ignored, but I've earned it, dammit. Multiple times iTunes even CRASHED MY LAPTOP when I tried to make it play the movie. Blue screen of death!! Considering this laptop is less than six months old, that is not something I was expecting to see!
So, please, either tell me how to get a refund or how to fix that damned program so it shows my movie.

Some basic information is necessary.
Captured it from what to what with what for what with what sequence settings in what program and using what cam.
I think you understand that without some detail how can we guess at what the problem is.

Audio and Video not sync (1ms difference) help.

Hi Guys,
I used an external recorder to record the audio of a training session. Since the results of that audio is much clearer than the echoy audio from my video camera, I decided to use it.
But I find it hard to match the video and audio together, even using Pluraleyes. There's a slight mis-sync in the audio/video no matter how I tried to shift them in the timeline (+/- 00.00.01s). Is there any way to be more precise than what I did?
Please help thanks!

Photo Booth: Audio and Video not syncing in the same time frames, really annoying

That's the problem.

Same problem here.
1. Reset ACLs
2. reset PRam reset SMC
3. repaired permissions
4. repaired disk
No issues found.
Reinstalled Mountain Lion....
issue is persisting.
FML
Machine seems to be running fine otherwise. Just happened to notice it when I tried to reord a short video of some guitar. Way out of sync. Horrid.
I made a new user account and the issue is continuing.
The only thing I haven't done is is completely wiped the drive and started fresh. Such a pain in the a## to do this. IDK. Definitely wasnt happening on snow leopard.

Audio and Video not synced P205-S6337

The audio on my P205-S6337 runs about 3-5 seconds behind the video. I have checked on the Toshiba downloads and upgrade pages and found nothing that addresses this problem. Any ideas from all you more computer savy folks out there? Thanks in aadvance for any pointers.

Um ... some useful data?
OS/CPU/RAM/GPU/vRAM ... version of PrPro ... and other programs or plugi-ins/3rd-party apps involved ... footage type/codec/wrapper ... such things would be very useful.

Audio and video not in sync. went back to previously finished projects and they too are not in sync. What could be the problem?

URGENT- DOING MEMORIAL VIDEO sound and video are off when sent to iDVD

I watch the video in iMovie and the sound and video are in sync. When I send to iDVD, the two are no longer in sync. I have made changes to the iMovie project since my last DVD burn. With the initial burn, there were no sound issues.
I've tried all of the following:
1. closing and reopening iMovie and iDVD
2. resending from iMovie to iDVD
3. readding the clip and removing the original clip from the iMovie project
4. restarting my computer
The only things I have not done are the following:
1. redownloading the original video clip from my camcorder
2. recreating the project
3. trying a different project to see if that one has the same audio/video issue (this will be my next step)
#2 above is literally so intense as I have a lot of editing on this. To make it clear to you, I have video footage of a memorial.... and after the memorial I chose little 20-30 second clips here and there. I don't have audio with those clips -- just iTunes music overlay.... so, those I don't need to worry about sound coinciding.... just the 30 minute clip that is the actual memorial service.
This is time sensitive.... it is a memorial video and I don't have time to redo the thing from the beginning, especially considering how long it took me to find those 20-30 second clips of the post-memorial.
Please help!

Yes... I had seen that.... and, yep, have the latest software.... and even rebooted my machine thinking that maybe it hadn't been restarted since the update (can't remember how long ago the update was).
I did a test run with a mobile size (it takes over an hour when I share with iDVD, which has been annoying with all my attempts to "fixing") file sharing with media browser and still the sound was not matched.
I started another project alltogether in iMovie and it does not have the sound issue when sent to iDVD....
I can copy and paste the more difficult editing I did between the "bad original copy" and my "do-over"... but, it seems to not copy exact length of each clip (it decreased it by a second each clip on the ones I copied over but that is weird since it did copy over the slowed % I had on the original) ..... see the more complex editing I have has the sound silenced and I have music overlay on that....
I have many more to go... and can't copy text directly from one project to another... in fact, there is a lot you can't just copy over.... I have to redo the music, special effects etc. This is not going to be a walk in the park if I can't find a way to make my "bad original copy" work.
Still looking for more suggestions (than to start all over), but will have to start over if I spend too much time making the one I have work.... then it becomes more sensical to just start over. I have quite a bit of time in the original, but if I can copy and paste the clips, that takes a majority of the work out.... but, if any of my copy and pastes somehow "corrupt" the sound sync on the portion that isn't silenced and music overlaid, then, there is a lot of work having to recreate all my edits from scratch.
