Sound delay After I record a video, in playback the sound is not in sync with my lips. Every video I record the words are delayed.

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 is a cumulative problem with potential errors entering at any stage in the broadcast chain where video is delayed and an equivalent audio delay is not added to counteract it. It can occur during post production, broadcast (at many stages), and even in disc mastering - and finally your TV may add more video processing delay (especially if HD or 4K TV) making it worse. The only way to correct it completely and have perfect lip-sync is to adjust (or shift) the audio relative to the video at the final output stage. That can fix lip-sync error no mater where it came from.

Since it has been documented that lip-sync error - even when not consciously noticed - causes viewers to perceive the characters and story as "less believable" , many cinema enthusiasts use external delay boxes made by companies like Alchemy2, Felston, Primare, etc.to intercept the audio and delay it to match the video perfectly via remote control.

I use a Felston DD740 and contrary to what the industry believes I can detect lip-sync errors down to the millisecond. I mean when I adjust the DD740 and achieve what looks perfect moving it a ms either direction looks "off". Most viewers will never see "perfect" lip-sync if they aren't performing such an adjustment while viewing.

Getting it "close" - perhaps within 30 or 40 ms - will allow most viewers to ignore it but the study done at Stanford showed the negative impact was still present.

The current theory to explain this is that our brains - even subconsciously - can't process the impossibility of sound before lip-movement and we look away from the lips to avoid the impossible and in doing this we form the same opinion of the characters as we have of people who don't make eye contact with us. Ironically "we" are the ones not making eye contact with the characters in order to avoid the impossibility of sound before lip-movement.

You can run your own test to prove this: Force yourself to focus intently on the lips and you will see lip-sync error you never noticed before. You were ignoring it because it was below your "threshold of recognition" and looking away could conceal it.

After the cable change and adjustment you didn't notice lip sync error because it was probably below that threshold but something ( a digital video effect in the broadcast possibly) boosted it above your threshold and you noticed it again. The only way to eliminate the negative impact is to look for the error and adjust it out.

Most AV receivers and some recent TV's offer a fixed audio delay to correct lip-sync error and that can usually get it close enough that most people won't consciously be bothered but masking the problem like that doesn't eliminate the negative impact on the characters and story.

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.

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:

http://en.wikipedia.org/wiki/Audio_to_video_synchronization

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.

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

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.

This is because of low light and low frame rates in the camera. It records the sound on time but the picture delays. In the camera's video menu, choose a higher frame rate to help this a little. Honestly though, If you want to shoot better video get a video camera.

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.

what are the connections supported on your pioneer player? i suggest try to isolate problem, change the type of cables, like RCA or HDMI cables.
