SOURCE: Sound/Video delay

Lip-sync error is a widespread problem caused when video is delayed and audio arrives too soon. Widespread enough that three different manufacturers make dedicated products to address it, in fact (see review link below for those three). It is present to some extent in essentially all broadcasts and DVD?s. If you have a recently acquired DLP, LCD or plasma display it may have added enough additional video delay to make it noticeable but lip-sync error comes from MANY sources starting at image capture and continuing through post production and broadcast or DVD encoding and it is cumulative. There is usually enough lip-sync error in broadcasts and DVD's to cause a negative impact on viewer perception (Research done at Stanford showed this.) Many people don't consciously notice it until it gets very large because it's such an unnatural phenomenon ( audio can't come before the action causing the sound in the real world) we apparently subconsciously avoid looking at the faces and seeing the lips move "after" the sound from them is heard. A study at Stanford proved this causes negative viewer perception even for those who don't notice it so this is something we all need to notice as you already have. For those reading this who haven't noticed it, take a close look at the LIPS - force yourself to overcome your natural avoidance mechanism that keeps you from looking at the lips - and you will see lip-sync error you never noticed before. I think you will be amazed that you could possibly not have noticed it before. You will be seeing what JC is seeing. I even see it now on CRT TV's and am amazed I never noticed it so it's very obvious some avoidance mechanism is at work. And back to JC?s solution: I'd recommend one of these digital audio delay units. That way you can correct for ALL cumulative lip-sync error no matter what its source might be. Any one of these units reviewed will correct it ALL. With any one of these units you can adjust for perfect lip-sync at the start of each DVD or broadcast and not disturb the image you are watching during that fine adjustment. I have had a Felston DD340 since 2004 (three generations earlier than the DD740 covered in the review) but it still has the most important feature of all these units from these three different manufacturers which is their "plus and minus" buttons on their remotes that allow you to tweak the delay while watching your material without upsetting the video your are watching. My av receiver has a built in delay of 80 ms which isn't even enough audio delay to offset the video delay my plasma display adds but even if it were it isn't practical to adjust it for the changes in lip-sync error from program to program and DVD to DVD since it overlays the screen with menus when making the delay adjustment. With my DD340 (and any of the units reviewed) all you have to do is press the plus or minus button until you get perfect sync. Here is the review I mentioned: [URL="http://www.audaud.com/article.php?ArticleID=3011"]

I have a sony tv plus soundbase connected by hdmi.on bbc and when watching dvds the sound does not sync.it is fine for all other channels and sky.I have used optical cable but there is no diff.


I had a look at a Soundbase manual, but it doesn't seem to be the cause of the problem. So it might be in the DVD player sound selection options. Since you have not specified any model numbers I can't go deeper into the problem.

Why does the picture from my vcr vibrate on my new vizio smart TV


Because the Vizio TV isn't capable of dealing with the unstable sync from a VCR.

There's no real solution to this from a TV manufacturer's perspective. In the era of flatscreen TVs they're all designed for the nice stable synce from DVD players, TV broadcasts, TiVos and PVRs, games consoles etc. VCRs are yesterdays technology.

You can spend some money on an external Frame Store Sync Stabilizer, but it will cost quite a bit (more than a DVD Recorder, for example). So it might be better to have those tapes transferred to disc either professionally or by buying a used DVD recorder and doing it at home.

Lip sync


Vizio HDTV- Lips out of sync

Anyone with a new Vizio E601i-A3 60" or 70" HDTV that is having audio "Lips out of sync problems" with a cable or satellite box.

On Comcast cable boxes (or others), here's what you need to do: FIND MENU for AUDIO or HDMI setup on CABLE BOX or Satellite Box.

FOR COMCAST

1. Turn on TV and have Cable box Turned OFF.

2. Press MENU on COMCAST REMOTE.

3. Go to AUDIO Setting OR HDMI Setting. (On cable or Sat. BOX)

4. Change setting from Auto to L-PCM. (Turn off cable box to exit)

This should resolve any "out of sync" lips to picture after commercials on HD channels.

*This is a handshaking issue from the cable box to the Vizio E601i-A3

The audio and video are not in sync


Are the movies you're watching store purchased DVDs? Sometimes with downloaded movies, the audio and video are just out of sync.

If they're store bought, it's possible that you've got a delay set in your receiver. Consult your receiver's operating manual to see if there's a "delay" option.

It's also possible that you're hearing that delay in the TV speakers.

If you've got the audio coming through the receiver AND the tv, you'll hear a slight delay when the audio's traveling from the DVD player to the television itself. This could happen "sometimes", if the tv volume is on, and not happen when the tv volume is off.

Sound doesnt sync up from direct tv to the speakers


hi, are you trying to get sound from your TV through your home sound system? I'm not quite sure what you mean about "direct TV" thing if that is a specific term. Please ellaborate.
If you have a line (audio) output on your TV then it could be easily connected to an auxillary line input in your sound system controller. hope this helps..

You will not only have better found, you will fix the speaker buzz problem.

Optical output on tv through dvd home cinema out of sync


Up front, i copied this from another site, so kudos to the OP there if this works for anyone...

Hi,
This same problem had been bugging me when I bought my LE37B650, everyone suggested adjusting the delay time on my AV amp but unfortunately mine does not have this function.

Anyway I finally fixed the problem using the following steps

Before you start make a note of your menu settings as you will have to reset them after this procedure

Turn off the TV then press Info -> Menu -> Mute in sequence then turn the TV back on again. This will get you into the secret Service Menu. Go straight to the AUDIO page of the menu. Don't be tempted to fiddle with things in service menu cos you can end up in a right old pickle!

In the AUDIO page you willl notice that there is a time delay set for the internal speakers of 100ms but for some reason this is not set for the external output so all you need do is dial in a 100ms delay there and that should sort the problem. Well it fixed it for me.

Note that as soon as you enter the service menu, all your other standard menu settings are lost and the screen will be set to dynamic for some reason so you have to go through and change everything back after you have done this.

Hope this Helps

This would suggest that you CAN fix the problem with an analog amp.

Also interested to see if a 2 year old thread is alive!
