Video and audio not in sync after encoding .mov to flv.

I have a .mov file and am converting it into a .flv file so I canimport the video into flash cs4. When I import the flv., and test the movie/export movie, the audio seems like the video is running slower than the audio. Anyone have an idea why?

Video and Audio not in sync after capture

Hi there,
This is probably a common problem, I have trawled the site but can't seem to find and explanation for it.
I'm capturing vide/audio into final cut pro from my SONY DVR. The video i have streaming into the sony DVR is from a small covert video device which records video/audio onto an SD card. SO I'm running that into the DVR and then DVR is outputting that as DV PAL firewire (uncontrollable device).
I'm capturing the 40 minutes of video as one clip, and when i drag it into the timeline the audio and video are WAY out of sync. Is there a simple reason for why this is happening?
It's almost as if not capturing it right.
I hope someone can help,
Thanks in advance.

It is interesting that you are having this problem. I recently purchased a brand new Mac Pro (a week ago) and I am using Premiere Pro and it is doing the exact same thing. I mean this video and audio is REALLy out of sync. I tried capturing an hour at a time, and 30 minutes at a time. Still, no luck. I was debating on getting Final Cut, but after reading this post I am rethinking not only Final Cut, but using Apple all together. Part of me thinks that it is not a Premiere or Final Cut problem but a Mac OS problem. But hey, what do I know. I only edit for a living.

Video and audio not in sync

Anybody else experiencing video & audio not in sync since upgrading to Lion? I have a MacBook Pro 15-inch, Early 2011 with
AMD Radeon HD 6490M 256 MB graphics. I mostly stream You Tube, Netflix, & news videos and occasionally watch movies I have in iTunes or on DVD, and since upgrading, I've seen out of sync video and audio in every one of these situations. Sometimes it starts out OK and then slowly deteriorates. Other times it just starts out that way and stays that way. Happens with all browsers as well as iTunes and DVD Player. Tried a few Google searches but haven't come across any postings reporting this with Lion, so I thought I would try here. Thanks for any confirmations and/or pointers to a solution if there is one.

Ahh...boom. I have it too. Forgot it was even there. I had it turned off back when running Snow Leopard since it was glitchy. Apparenty, I somehow reenabled it and wasn't even aware it was on since its volume was turned down. After disabling it, all video & audio appears to be in sync.
boom...the sound you'll hear as I nuke it from my system.
Thanks efrancis76 for figuring this out. Much appreciated!

Audio not in sync after encoding to H.264 Blu ray

I have recently been trying to author my first blu-ray and keep running into new problems everytime I think I find a new solution. My new problem is that when I encode my sequence from Ppro CC to H.264 Blu-ray and place the video file and audio file into Encore CS6 the audio seems to be falling out of sync. I tried placing both files into a new PPro sequence and checked the playback and they are also out of sync there.
Things I've tried:
1) I went back and just encoded the audio from the sequence but this time I switched the audio coding to DD 320 bitrate instead of PCM. When I placed this file into the PPro sequence the playback was perfect. However, when I try placing the same two files (video and audio) into Encore they are out of sync.
2) I decided to take the encoded video file and place it back into the original PPro sequence and use it to replace the original video track. The playback again fell out of sync. Since this sequence had the original pre-encoded audio track, I came to the conclusion that it is actually the video that is not keeping up with the audio once encoded.
I am trying to encode to 1920x1080 HD 23.967 fps H.264 Blu Ray. I know I can just encoded to .avi match source and then let Encore do the transcoding, but figuring out this problem is a learning experience for me. Does PCM or Dolby Digital make a difference? What is the best way to do?

It sounds like things went wonky the first time around. Try exporing the whole thing again.
PCM is higher quality. Blu-rays have a lot of room compared to DVD, so I feel it's often the better choice. I'd recommend using DD only when you have to. But considering that I've put 3 hours of HD onto disk and still only filled 17GB, I think it's the very rare occasion when you'll run out of room and have to use DD on Blu-ray.

Video and audio not in sync. Other answers here do not help.

My audio and video are not in sync in many streams but some are OK.
I do not have any extensions, add-ons and I am using the default theme. I have disabled hardware acceleration. I am now running in Safe Mode and the problem persists.
The video and audio sync for the first few minutes and then they work their way futhter and further apart, usually several seconds out of sync. I don't think this particular situation has been covered in the other posts.

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Video and audio not in sync (ALSA underrun occurred)

Hi, after a recent system upgrade (upgrade log here http://pastebin.com/1gRwexFr), video and sound are not in sync anymore. The problem occurs in mplayer instantly, and in XBMC after a while (the audio is slowly getting out of sync). The error message I get continuously in XBMC is "ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred". The error I get in mplayer is "[ac3 @ 0xf46b40]frame sync error" I did another system upgrade and the problem persists. I'm using Terratec Aureon 7.1 external sound card and linux 3.3.3-1-ARCH. I'm not using pulseaudio, just alsa.
EDIT: I downgraded (sudo pacman -U linux-3.2.13-1-x86_64.pkg.tar.xz linux-headers-3.2.13-1-x86_64.pkg.tar.xz linux-api-headers-3.1.6-1-x86_64.pkg.tar.xz dbus-1.4.16-1-x86_64.pkg.tar.xz dbus-core-1.4.16-1-x86_64.pkg.tar.xz glibc-2.15-7-x86_64.pkg.tar.xz) and the problem seems to be gone. I'm suspecting the kernel upgrade broke it..

See what buffer size you end up with. Start mplayer, and run:
cat /proc/asound/card0/pcm0p/sub0/hw_params

IPod Video and Audio not in sync

My iPod is having some issues with movie playback.
When I transfer long videos like movies, the video will always become faster than the audio towards reaching about an hour into the movie/show eg. the mouth moves, after about a sec then the audio comes out.
I've updated my ipod to the latest firmware/software but to no avail. My movies are all in mp4 format. What should I do?

tried that already. Anyway the mp4 file works fine on my com, the audio and video is sync thruout the whole show on my com

Video and audio not in sync v 7 itunes

since downloading this version when attempting to play previews of tv/movies on itunes the video is slow to play back sort like frame by frame (as well if i buy a tv show). of course the audio is all out of sync as well. the sound is perfect and the picture clear. this never happened in the previous version of itunes... any ideas?

Video is better for me since disabling the Direct3d acceleration as described in the FAQ, but it's still not up to where I'd like it. If I right click on a podcast and select "Show in Windows explorer", and then open the video in another player that supports MP4, like media player classic, or VLC, it plays much better, and it has the screen refresh synchronization that's inexplicably missing from the Windows version of QuickTime.

Video and Audio not in sync problem

One of my videos I converted is out of sync (audio and video). I converted it through videora and nero recode. Any suggestions on what other method I could do. Thanks.

I noticed you have nero recode. Do you have nerovision express? if so, try converting it to an .mpg using the make CD... super VCD option. then convert that file to an .mp4.

Video and audio not in sync, lags in swf.

Hi, I am making a kinetic typography for a class and I am having trouble with lagging audio. There is no problem when I work on it at school, just at home.
The clip is about 2:15 long. Right from the beginning when I export and play as an swf, the video begins but the audio lags and starts a second or two later. This is quite frustrating. Is there anything I can do to fix it? My teacher says it may be my video/graphics card at home but I don't think that's the issue. Any thoughts?

The audio is on a seperate layer on my timeline. How can I set it to stream? Sorry, I'm rather new with Flash.

Video and audio not in synch after 11.6 update

Ive updated to the 11.6 version flash player several times and this out of synch issue has happened every time. In the past I just went back to older version. Now the sites I use (youtube, letmewatchthis.com...ext) wont let me use the older version at all. So once again I updated, and of course I have the same problem. The audio appears normal, but the video is dragging, going into a slowmotion kinda thing. Im using Mozilla Firefox, my cpu is a desktop windows XP service pack 2 Pentium 4 1500 MHz 1.50 GHz 512 MB of RAM (yes I know its a pretty pathetic desktop by todays standard, but its all I got for the moment) Ive went down the list on the troubleshooting page and did all that I could. Deleting browsing history, removing flash cache, disable hardware acceleration. Im all out of ideas. If someone could help that would be splendid.

Can you try out latest 10.3 build to see if that works for you? It should work on most sites.
Where can I find direct downloads of Flash Player 10.3 for Windows or Macintosh?

Video and audio not synchrone with apple tv after update mountian lion on macbook pro

i have a problem with my apple tv. after i bought and instaled mountain lion on my mac book pro i have trouble with apple tv and my laptop. when my laptop conects with apple tv most of the time my wifi doesnt work on my macbook but on my apple tv it stil does work. when it does work and i play a movie of my own by using itunes the first second the video and audio is synchrone but after that audio is at normal speed but the video gets behind. and i am getting sick of it. does sumbody reconize the problem and can help me with this problem?????

Same issue here- I can airplay my amazon prime library just fine from my iphone 5 but on my macbook- (mavericks, 15 inch 2013 retina with quad core i7, nvidia 650 M and SSD) it just sputters and lags.
I have noticed web video is considerably worse than local content, giving me pauses of up to 2 or 3 seconds in which video stops but audio continues in the amazon player. Youku video, however, seems relatively stable. Our subscription speed is 25 mbps, so that should be plenty to stream SD video from Amazon and doesn't account for why it would be nice and stable from the iphone, but not the mbp.
Playing light, locally hosted steam sidescrollers like Limbo is better but gives periodic drops in framerate on the Tv. when mirroring the framerate remains steady on the MBP screen.
Games airplayed from my iphone seem relatively stable, though with a noticably lower framerate on the TV than on the phone.
It seems these issues have abated considerably since yesterday's Apple TV update, but are still curious nonetheless and I'm not sure that the update yesterday was specifically meant to address those issues or if I'm just getting a time with less network interference now.
Comcast recently installed a new router/modem/phone combo, replacing our old separate modem and router setup. I'm going to test if putting the network on a different channel helps.

Video and Audio not synced on .mov file in final cut, but perfect in QT!

I recently just captured a miniDV tape onto final cut. I captured it in 23.98fps. After I captured it and opened it up in final cut's sequence, the video and audio was not synced at all. it's way off and even when i try to move the audio around on the timeline and get one voice synced up, about a minute into the video it's off again.
i tried opening the video in quick time under the captured scratch folder, and when it plays in quick time, it's perfect. there is no sync problem at all. only when i open it in final cut is there a problem.
does anyone know how to fix this or what is going wrong?!
HELP ME

well i mean we recorded it in 24PA, which is what we've been doing for this project of ours. And when we go to capture in final cut we choose the Advanced Pull Down setting. So in the end, our video is in 23.98 fps.
I just thought I'd mention that just to give more details. idk if it's helpful or not

Why is Audio out of sync after encoding?

I have encoded a 60 minute film using separate video and audio files -- quicktime for picture, AIFF for audio. In the DVD Studio Pro project, they are perfectly in sync. But in the encoded DVD they are playing out of sync by over 1 second.
I've encoded the same movie with different versions of the soundtrack several times before with no problems.
Anyone have any ideas of what has happened and how to fix it?
The Quicktime and the AIFF were on different drives when I was building the project. Could this have had any effect?
Using DVD studio pro v4.0.2
Powerbook G4 Mac OS X (10.3.9)

Nope, I am a strong believer if it ain't broke do not fix it, and personally I loved 10.3.9 - in fact I say away from updates unless absolutely needed and then I bring them onto different machines. Unless something changed in your system, I would try standrad troubleshooting (repair permissions and delete prefs) and A.Pack the audio
Not to say I do not have machines running Tiger, but Tiger (particularly some of the newer versions) I find to be a PITA - around 10.4.6 or so there are weird security things happening which messes up installing software. In fact I just zeroed out my tiBook, and did not add some software that I forgot about until after 10.4.8 was on and it does not install. I would have to zero things out again. Install the software over 10.4.1 and then try again.
Unless you want the Universal Suite (which is good for most things except DVD SP which has issues) nope, no Tiger none of the new stuff, unless you have a few machines to play with
