Editing Guidelines Please remember these guidelines when editing a film article: If a non-film article already exists with the name of the film that you are trying to create an article for, disambiguate and use (film) in the title: Film Title (film) For more information see: Wikipedia:Naming conventions (films) When writing an article about a particular film, the general format should be a concise lead section, followed by a plot summary of no more than 900 words, production details, a cast list, a reception section, and references. Create an Infobox that tells all pertinent information about the film. Article upgrading needed: You can help! WP:IA   Stub to Start-Class Upgrading Instructions for Films Note that instructions for articles on other types of film topics within the scope of WikiProject Films are currently under development.

[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] 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.

I removed the whole section as none of them has sources. BJ^Talk 07:29, 6 December 2006 (UTC)

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] Actors Lip syncing to songs

When watching some TV dramas I've noticed that the actors are lip synching to music in the finale, could someone help put that in. Luckystars 22:35, 1 May 2007 (UTC)

[edit] What is "Lip singing"?

In the lede it states People often get this term mixed up with "lip singing." What is that? there is no article about it and no expalnation of what it is or why someone would confuse the two. Benjiboi 18:18, 1 October 2007 (UTC)

[edit] Lip sync#Lip-synching in music section too long

This section should be broken up with subsections for readability and clarity. Benjiboi 17:38, 20 December 2007 (UTC)

[edit] Merge proposal

I know the two are error-ridden, but I hope that there is a consensus to merge lip sync error into this article. Maybe if the two are combined, the attention that this article gets will improve the former article. --Kannie | talk 01:46, 25 December 2007 (UTC)

I'm mixed on the proposal and Lip sync error is all of how many days old? Perhaps that concept could be developed a bit better to encompass the technical aspects that would seem inappropriate here and then summarized in this article. Personally I would give TVtech some time, a month maybe?, to flush that article out a bit and provide some external links for those who deal in the issue or wish to learn more. My hunch is this article is attracting more pop culture hits so agree that two articles may make more sense in the long run. Benjiboi 02:36, 25 December 2007 (UTC)

[edit] Merge proposal comment

The issue of singers lip syncing their music and the technical lip sync problem experienced in television systems are so diverse that merging everything that comments on one or the other seems unproductive. I personally would like to see the two split into entirely distinct subjects. —Preceding unsigned comment added by TVtech (talk • contribs) 02:12, 25 December 2007 (UTC)

I'll comment here rather than that article for now. It would be quite helpful to introduce more industry related articles and links so anyone interested in that field can learn more even if we provide a short summary. It would be best to expand the article so the general reader can better understand that it impacts their daily life if they ever watch television or related media.
