Lip sync not good

These are some pretty lame answers. Atmospheric conditions???
Lip-sync error is always present to some degree because there is NOTHING in the video and audio signals to define when they were ever in sync. Most people look away from the faces and lips since it is impossible in the real world (sound can't come before the event that creates the sound) and our brains can't reconcile the contradiction of reality. That's why most don't notice it. But when video is delayed and audio arrives too soon and it's so bad you can't look far enough away to ignore it - then - it's in your conscious and you see small errors you never noticed before. You can't un-ring the bell but you don't even know it happened and think something changed in your equipment. Even when it goes back to normal you still see it because your defense mechanism to the impossible is broken. The only true fix is to delay audio to match the video delay and several companies make devices to allow doing that via a remote. (Alchemy2, Felston, Primare, etc.) You need a remote and a way to tweak the delay because it changes between every source and even between programs on the same channell. Again because there is NOTHING in the signals to define when they wereEVER in symc. Google LipSync Error Correction and you will see what I am saying. A study at Stanford 25 years ago proved it causes viewers to have the same impression of the characters (whose lips they are looking away from) as we have about people who don't make eye contact: That they are more agitated, less convincing, less successful, etc. For that study Google "Reeves and Voelker Audio Asynchrony" and I'm sure you will find it as it is often quoted.

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.


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


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

I seem to have a delay between the lips moving and the sound coming out of the tv how can this be fixed

Welcome to Digital TV. Not much you can do about it. Unlike analog video where the A/V was in perfect sync, digital video moves much slowwer that its audio cousin, hence the latency. Save for installing an expensive audio delay device, you will unfortunately just have to get used to it.

It's the nature of the beast. The TV has to process the digital video bitstream more than the receiver has to process the audio so the result can be a gradual lagging of the video behind the sound...

Some receivers have a sound delay control which you can use to try to sync them up. You didn

I have a Yamaha RX V800 AV Receiver is their an lip sync adjustment for internally with this amp.

This monster has a lot of built-in opportunities to tune or mis-tune the sound but nothing to deal with the effect you're addressing.

A discussion of lip sync:

  • There is extensive use of audio and video signal processing circuitry with significant delays in television systems. Particular video signal processing circuitry which is widely used and contributes significant video delays include frame synchronizers, digital video effects processors, video noise reduction, format converters and MPEG pre-preprocessing.
  • The video monitor processing circuit may delay the video stream. Pixelated displays require video format conversion and deinterlace processing which can add one or more frames of video delay.
  • A video monitor with built-in speakers or line-out may not delay sound and video paths by the same amount of milliseconds. Some video monitors contain internal user-adjustable audio delays to aid in correction of errors.

    I am having lip sync issues with my led tv when using my Kenwood VR-407.

    Therre is serious time delay issue in the processing of the audio and the video section. It is possible that the time delay circuit could be aggravated within the processor IC. It is important to use a test signal to clarify. If the TV is working fine with all other inputs and cable then you must check your kenwood for sync issues. I think this will require very professional attention and may be beyond the scope of this forum. Good day

    I have a JVC G40 DVD home theater system and when I play DVD's the voice and picture don't match up. Specifically, Peoples lips move and then a second later what they say is do I fix this?

    When viewing on Digital TV:-
    Sometimes Audio and Video signal can not be transmitted simultaneously due to additional process time for the video signal compared to that of the audio signal.
    Often video signal takes more time than the audio signal to convert from analogue signal to digital signal in the Digital TV.
    It may result in mismatch of the picture and sound.
    In the TH-G30/40's HD AV Sync menu, you can adjust the audio signal delay for simultaneous AV signal transmission
    1. Delay time can be varied in 10msec steps.(0 to 300ms)
    2. Delay time is different between TV Brands.
    So you need to adjust the delay time for correct lip-sync.
    The adjustment is listed in the instruction book page12

    I have a philips DVD home theatre system HTS8100. Its fine except that NO dvds play in synch. I have checked them on my normal DVD player & they are fine. The synch button on the remote sometimes fixes...

    Synch problems on Philips machines can be caused by the video output setting.

    Usually there are 3 options for video output:
    • PAL
    • NTSC
    • AUTO
    PAL & NTSC force playback in that setting, regardless of DVD format, and sometimes cause a time delay in the conversion.

    Try changing this option to AUTO. IF you have a modern TV, it should allow both PAL & NTSC playback.

    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=""]
