At this time, the preloader will only run on YTMNDs where the creator has enabled "Synchronize" in the YTMND creator. When a user accesses a synced YTMND, a flash animation will appear, showing the YTMND logo. The preloader will first load the [[MP3]] with a progress bar showing the percentage of how much the file has loaded. Next it will blink a loading message for the image. Once both files are loaded, the background image will appear, and the preloader will loop the MP3.

=The Basics=
:When you create a site, click the 'Yes' radio button under 'Syncronize'. You can use the Delay to tweak your audio. If the image is trailing your intended audio, or if it losing synch after a couple loops, try increasing this value. (It's in milliseconds, so a value of 100 = 1/10th of a second.). Also, your sound clip must currently be .mp3.

+
;It still doesn't sync for me.

:It's probably going to happen for some people. It still hooks into the traditional method of displaying images, so you'll be susceptable to problems from a bloated OS, low memory, etc, etc.
+
 
+
;Flash? But this is YTMND. Flash is for Newgrounds!
+
:Flash is currently used as an audio buffering and timer/polling utility, with proxying into Javascript. The image is still displayed the "traditional" way, using a .gif or .jpg as a background image. Eventually we're hoping to have .wav support, which will dramatically decrease the filesize and have seamless looping. Also, another benefit of this is better browser compability (whereas the other way uses specific methods for IE and Mozilla/Firefox.)
+
 
+
;Browser compatibility? But it's not working Opera/Safari/KewlBrowser.
+
:Some people are having problems. I *pretend* to be looking into it.
+
 
+
;Why is it crashing in IE?
+
:Not sure, because this was fixed. If you're still having a problem, make a post about it.
+
 
+
;What was that about .wav support again?
+
:The support is actually ready to go, but the problem is a 64-bit compatible conversion utility for the .wav files. If/once that gets going, the download time for .wav loops will be dramatically reduced (about 1/5 the original size), will sound just as good, and will loop seamlessly.
+
 
+
;Isn't this preloader going to create a lot of crappy sites?
+
:No, the user will.
+
 
+
;It just isn't working for me.
+
: If it doesn't work and there's nothing you can do about it, you can disable it by unchecking "Use flash preloader when available" on your options page.

;It sucks!

Synchronization, or sync is the matching of images with audio to improve the impact of both. It is a vital part of many YTMND, but what seems like a simple task can actually be quite difficult. The purpose of this guide is to not only instruct on the basic idea of sync, but to also share the tips and tricks that can only come with experience.

The Building Blocks

Any sync'ed YTMND will require the use of a gif, an mp3 and the Flash Preloader.

The Gif
This guide won't be covering gif creation (will link it when someone makes the page for it), but the MAXIMUM file size that you want your animated gif to be is 3mb.
The Mp3
The sound file has to be in mp3 format because the flash preloader does not yet recognize a wav. While this is disadvantageous due to the short pause the mp3 codec adds to the end of an mp3 file, we'll just have to live with it until Syncan wraps the the .wav support for the preloader.
The Flash Previewer
As easy to use as clicking a checkbox. Check the wiki for the previewer if you seem to be too retarded to handle that.
