Sound and video become unsynced when recording

I've been capturing Hi8 tapes via a Sony digital-8 camera using Quicktime's record feature. I've noticed a very big and annoying problem. As the video is recording the sound gradually unsyncs from the video. The sound starts to get further and further behind the video. By the end of a 2 hour tape it's like 5 seconds off. Has anyone else experienced this or does anyone know how to fix it? I know it's not the tapes because they play fine on the camera. The same thing also happens when capturing using iMovie. Please help! Thanks in advance!

Some more info...
I'm importing a series of home movies that were recorded over the course of 20 years using 2 different video cameras. This issue appears to only be happening when I import video from the older tapes (the ones recorded with the first camera). My hunch is that these were recorded with 12 bit audio and quicktime is expecting 16 bit. I'm going to try and re-import an older tape and switch the bit rate on the camcorder to 12 bit to see if that fixes the problem.

The sound and video become unsynchronized when the off-line recording was created.

Hello,
I recorded a 1.30 hour meeting by using Adobe Connect. I want to edit the file and split in small time. So I save the recording in local by clicking "Make Offline". When I play back the file from local, the sound and video become unsynchronized.
Any idea and how to sort it out.
Thanks in advance,
Nicho

As I recall, there is an issue with Windows 8 and the offline recording function. Not sure if you are using Windows 8, but it may be worth trying to do it on another computer.
However, before you go down that road, know that the FLV versions of the meeting recordings are notoriously difficult to edit. If you don't need to have the recordings in a different format, I would recommend that you do the following instead (will be much faster overall).
Take the URL for your meeting recording and add /output/YourNameHere.zip?download=zip. You can name the zip file whatever you want. This will pull the recording source files down to your local computer. Next, browse to a desired location in your Content library in Connect and re-upload that zip file. You can name it whatever you want, and even create a custom URL for it. Once it is uploaded you will have a second version of the same recording on your server. Just re-upload that zip file as many times as needed. You can then edit each version of the recording separately, allowing you to create as many versions of the recording as needed.

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.

Sound and Video are choppy when running on battery

When I try to watch a DVD the video and sound is choppy or if I just listen to a CD or MP3 the sound is choppy. I think that I set all of the power options to maximum performance while on battery but that did not seem to make a difference. Can anyone please help me?
Thanks

I went through an annoying password reset process to post on here, haha, I was experiencing this issue and managed to resolve it for a flash animation I was making that was going to be sent out; thus fixing it for myself wouldn't change things for others. I know this is old, but if anyone is in this position, I hope it helps.
I was using Swish Max for my scenario.
Under the Export Settings, I found that by default it was using SWF Version: SWF8 - when it had the option to go up to SWF10. I changed it to 10, and set the hardware acceleration to Level 1 - Direct.
I exported, and it still didn't work. The music was choppy as heck and terribly inconsistent with speed. I even created a preloader, which appeared to work but didn't resolve my issue.
FINALLY, I kept it at version 10, and found that it had an option that said "Preload Content: Disabled." I set that to "At Preload Frame" and though I had a loading animation setup to do the preloading, I still placed a preloadcontent keyframe at frame 1. Then I set Hardware acceleration to Level 2-GPU and exported.
IT WORKED. The terrible, seemingly non-fixable audio cracking lag was gone and it worked flawlessly.
Hope this helps someone, I originally found this when I was trying to find a fix for the issue.

The latest iMovie do not seem to be working properly. the photos and videos become distorted whenever i attach them to the templates. in one case (Blockbuster Trailer), the video skips thereby making it not in-synch with the music. what should i do?

I wonder if another provider would really be much different? Read some of the other carrier forums - seems to be the same story everywhere.
I'm not disagreeing with you - I've found that I am usually more informed about Verizon policies and procedures than some of the reps in our local store.

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,

Loss of sound and video playback on ENVY X2

Every so often, more often than I would like, my HP Envy X2 loses sound and video playback capabilities; any ideas anybody? The concept of this machine is great and have had it for the past 9 months but this loss of sound and vision is so unpredictable and frustating...

Hi Brumage,
I saw your post regarding the sound and video issues and I will be happy to help. Do you get any error messages when this happens? Have noticed if it is a particular site like YouTube or program that you are using when the issue occurs or does it occur on all programs? When you restarted the Envy X2 does the issue go away?
I would start by suggesting that you make sure all updates have been installed through HP Support Assistant and Windows Update.
What operating system are you running? What is your product number?

When I watch a movie in iTunes of Apple TV (2gen) and I want to move it few seconds/ minutes and more backwards then it like "losing its mind",
the video jumps forward (a lot forward) and the sound stays the same, so ther is mismatchment between sound and video.
What can i do to solve this problem?
Thank you!

Am I the only one suffering this issue with the video transcoding?

Sound and video are choppy since installing Flash Player 11.3

I'm having a problem here! Since I updated Adobe Flash Player 11.3, the audio and video are all choppy when I play Adobe Flash game apps in Facebook! Even when I disabled hardware acceleration, the sound and video are STILL choppy! Even I watch a YouTube video and the sound and video are a bit choppy! There's DEFINITELY some sound issues in Flash Player 11.3! I'm using Firefox 13 in Windows XP SP3. I'm wondering if you have any answers for the sound issues in FP 11.3.

Onboard sound and video IRQ prob

Well I have norrowed down a prob I believe is with the sound and Video using the same IRQ.
Both are using irq 16...
Why windows would put them on the same irq is beyond me.
Is their a way to change this?
Mobo is KT4 ultra with c-media sound
video is geforce4 ti 4200
System keeps rebooting when in games.
I just did a fresh install and installed drivers and bleh same thing.
I also turned off plug and play in bios. which microsoft recommends.
Any help would be great
r00t 3:16

Well considering their is a alot of IRQ's and half of them aren't in use you would think ms would not assign a video and sound to the same irq.....
At any rate. Im not sure what games you play but most games check to see if your sound card is working before it loads.
So that won't work.
I didn't have any problem with this system until I formated and redid everything I should of just stayed with it as it was.
Then the sound was on irq 16 and the video went to irq 128?
Thats right 128....
I didn't have to disable APIC either.
Although I did however have plug n play support disabled in the bios.
I also installed all drivers and devices before I added the service pack.
Maybe ill just get a different sound card.
Who knows.
But at any rate IRQ 5 is reserved for sound cards from what I read online. Unless you have a SB series they like irq's 7 or 9....
Anyways ill let everyone know what I did then.

Sound and video problems?

ok here is the deal, i got all the latest drivers for my system.
i got the
MSI 875P NEO LSR mainboard
p4 3 ghz with HT
with 1024mb ram
160 gb s-ata
geforce fx 5600 XT/256 mb
soundblaster live 5.1 sound
when i play heavy games like HALO or Need for speed my sounds and video works not correct BUT it should not be a problem because my amd 1800+ with gforce ti 4200 did better
i think it's the mainboard but does ANYONE has an solution or the same problem?
o yeah my system reboots sometimes when i put new hardware on it (had it with my USB modem 4 ADSL)

This sounds like it is your PSU giving troubles. What wattage is your PSU, and what are the 3.3v, 5v and 12v ratings on the PSU? (You can find out this info on the sticker that is attached to the PSU)

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

The mini dvi on the MacBook will only support video, in order to get audio you'll need to a cable from the sound out port to the sound in port on the TV.

How do you get sound and video from a macbook pro (before 2010) onto a 2010 toshiba 40" tv?

Any help on connecting a macbook pro (late 2009) to a 2010 toshiba 40" for both sound and video? I have the mini-hdmi cable, but have no idea about running sound through the tv. I can use the headphone jack, but don't know where to connect it to on the back of the tv. Am I supposed to change any settings on the tv or computer to allow the sound to go through the tv? thanks for any help.

You need a stereo mini to RCA break out cable.

[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.
