[edit] animation
Computer animation is far from the only type of animation to use lip-sync. The article has ben updated to reflect such. --b. Touch 20:42, 7 Jan 2005 (UTC)
- Isn't there a special term for the synching that is done translations of animation? Maybe it's just an anime fan term--I'm not sure. gK ¿? 21:12, 7 Jan 2005 (UTC)
[edit] Audio video Lip Sync
Lip-sync error is a widespread problem and not limited to any specific equipment but occurs anytime the video is delayed more than the audio.
The best explanation I have seen on any of the forums was from the member above who indicated it might take 60 ms audio leading the video to cause a user to notice it. We call that the "threshold of recognition" and it varies from 15 ms for some users to over 90 ms for others. When video delays add up causing a cumulative total greater than your particular "threshold of recognition" it will bother you since in nature audio can never be ahead of the event which produced it and our brains can't process that impossibility. Lagging audio is a natural phenomenon as sound travels about 1 ms per foot so it is much less noticeable.
Unfortunately, however, once that threshold is passed and the lip-sync error is noticed most viewers can detect and are then bothered by much smaller errors in some cases down to a few ms if they are really focusing on it. Some newer Av Amps also offer a compensating lip-sync audio delay but all that I have seen put it in set-up where you can't see the video and hear the audio while adjusting it. Most only have a single delay setting which isn't adequate since things like progressive scan conversion add about 35 ms of video delay so you really need different delays for different sources.
Ironically, the high end displays like LCD, DLP, and Plasma with their video processing requirements and inherently slower displays are often the "straw that breaks the camels back" pushing the video delay beyond that "threshold of recognition" and the larger image size of Hi Deff have made the problem worse.

Your TV (and my HLN617W1) have a video processing time that's longer than most TVs out there. It's specified at 60ms max. That is the threshold where most people will begin to notice the delay. If the source signal also has the video delayed, as it often does, added to your TV's video processing time, you begin to notice the sync issue. So, it's not caused by the TV or the source alone, it's a combination of added delay. Samsung is fixing the sets to lower the delay range down into 40ms, for those customer that complain.
[edit] Singers that have been caught lip-synching
Add: just about everyone who's appeared on Top of the Pops, CD:UK etc!
- Unless it has been covered by a notable source that the signer got caught it should not be added. BJTalk 07:29, 6 December 2006 (UTC)
[edit] Definitely not wrong
I disagree with people who think lipsyncing is wrong. As far as males, including myself, we watch these woman perform to watch them perform, most of the time not for singing. Some pop music is okay, (although that's just my opinion). I really don't care if someone lipsyncs (even if it's my favorite "singer"). The problem I have is when ugly women like Ashlee Simpson (which many people like for some reason) try to dance and lip sync and screw up. Other than that, no big deal whatsoever.
[edit] References
All the accusations of lip-synching by specific performers should be referenced or removed. What we have now is a lot of rumors and guesses (both good and bad guesses). If you can't find a ref to cite to back up the claim—not that there was actual lip-synching, which is usually controversial, but just whether there was a claim of lip-synching—then it should be removed.

Just a note -- I wrote my masters thesis a bunch of years ago about lip syncing and it in cludes many references and sources. Feel free to mine it for documentation. Here is the table of contents -- if you think it is useful, email me through the link on this page and tell me how/where to post the whole darned thing for posterity's sake. http://worldcatlibraries.org/oclc/30709834?tab=details
[edit] Why lip sync?
The article goes into great detail as far as techniques of lip synching are concerned, but there is no section explaining why some artists choose to lip sync. Wikichange 01:45, 24 September 2006 (UTC)
[edit] POV
I don't believe this page should single out Britney Spears. There are many other artists who lipsynch more so than Britney (Duff, Lohan, Lopez. etc...)
