I modified that script that animates agif thumbnails.
Click on options in the top right corner and paste this shit into your User JS.
$('document').ready(function () {
var animateGif = function () {
if ($(this).children('img.post-image').attr('src') != '/static/spoiler.png')
$(this).children('img.post-image').attr('src', $(this).attr('href'));
}
$('div.file').children('a[href*=".gif"]').each(animateGif);
$(document).on('new_post', function (e, post) {
$(post).find('div.file').children('a[href*=".gif"]').each(animateGif);
});
});
It should animate all of the apng thumbnails on this board.
Fuck yeah, APNG.
It isn't working for me!
How feasable would it be to install Mozilla's modified libpng in place of the default one onto your own computer? This could possibly make image viewers support apng.
Hahaha
mp4s and webms
So, /apng/. The other day I saw someone posting a soundless webm. Now this triggered my autism something fierce, so I went about trying to convert it to an apng. I opened up my trusty terminal emulator and converted the webm to a png image sequence using avconv (ffmpeg). I then assembled the image sequence into apng using apngasm. The result was a terrible, steppy mess. Like it lingered on each frame for too long. No matter how I adjusted the framerates, I just couldn't get it right. I tried again with a much, much shorter mp4 and the result was the same, so it's likely not the length.
/apng/, what's the best way for a humble GNU/Linux user like myself to convert a short video clip to an apng without using gif as an intermediate step? The gif format just fucks with the quality and is better left out of the process.
APNG plugin for GIMP
I'll show you how to get this old plugin running on GIMP 2.8 for Windows 7 x64.
First you need to get the required files:
http://www.mediafire.com/download/ubme5oy751zw0zh/gimp-apng-0.1.0.win32.zip
The zip contains 2 files:
>file-apng.exe
>file-apng.ui
These files need to be copied in specific folders, the following paths assume you did a default installation of GIMP. If you didn't , it shouldn't be hard to locate them.
file-apng.exe
C:\Program Files\GIMP 2\lib\gimp\2.0\plug-ins
file-apng.ui
C:\Program Files\GIMP 2\32\lib\gimp\2.0\plug-ins
IMPORTANT: Please pay attention to this last path, notice this goes into the "32" folder, this is NOT the same folder were you copied the first file.
You will need to navigate to :
C:\Program Files\GIMP 2\32\lib\gimp\2.0
THEN CREATE the "plug-ins" folder
THEN PASTE file-apng.ui inside that folder.
Next we'll see how to use it to load and export APNG files inside GIMP.
we'll continue this later tonight
APNG is the animated extension of the PNG format. It has many advantages over GIF that you may not be aware of.
PNG
-has far better compression than GIF due to not being locked down to a proprietary compression scheme
-is not limited to 256 colors (GIF actually isn't either but file sizes explode because you lose compression past that)
-is not limited to ~50 frames per second due to calculating frame display times in 10 millisecond increments; APNG has much finer frame rate control
APNG is especially good at traditional 2D animation. WebM, a video format, animates like most videos with heavy image compression over every frame and is able to achieve very small file sizes at the expense of visual fidelity. In contrast, like AGIF, APNG has the advantage of outright discarding visual information that doesn't change from one frame to another ("alpha channels") while being a lossless format. APNG also provides superior file sizes compared to WebM's lossless animated-supporting image format sibling, WebP.
/apng/ banners
Wouldn't it be snazzy if we had some animated PNG banners for this board?
Any thing on ajpgs?
I would really like to know
anime is bad for you
anime apngs
anime pangs
APNG is only dead because chrome doesn't support it
How do we get the botnet to support apng?
Spooks.PNG
You know I was think for the 31st of this month we can get some scary GIFs and convert them into PNG.It be pretty nice to spoiler them and freak people out.
What do you say Anons?
APNG Tools
SO YOU WANNA MAKE APNGS?This thread is for tools of the trade. Here are some tools I have found useful so far.
http://gif2apng.sourceforge.net/
Convert your decrepit old GIFs to glorious APNGs.
http://vdubapngmod.sourceforge.net/
VirtualDub mod for APNG dumping and loading support. Allows you to create APNGs from AVI files. If you're planning on using a frame rate that GIF doesn't support you should start here! VirtualDub usually doesn't make the most optimized GIFs or APNGs so that's where GIMP and other optimizing tools come in.
http://registry.gimp.org/node/24394
GIMP GAP plug-in for opening and saving as APNGs.
I haven't gotten this damn thing to work properly myself but as I use GIMP regularly for making GIFs I imagine it would be extremely useful for those that can get it working.
http://sourceforge.net/projects/apng/files/APNG_Optimizer/
Optimizes your APNGs. Doesn't quite do it as efficiently as GIMP GAP but you take what you can use.
http://sourceforge.net/projects/apngasm/
Sort of useful tool for assembling from individual image files, could really use a visual display though; there's currently a funded kickstarter project to build one from it
https://www.kickstarter.com/projects/374397522/apngasm-foss-animated-png-tools-and-apng-standardi
http://littlesvr.ca/apng/
A nice list of APNG tools, haven't gotten around to evaluating them all yet.
We live in a world surrounded by plebs.
Plebs who save every god damned image as a jpeg and don't think twice about it.
Plebs who think webm's with no sound are the perfect replacement for gifs.
Why? Why does the world not know? PNG is there to save them from their sins, yet they pay him no mind. Why do they hurt the great png so?
APNG from videos
Testing some APNG from videos.
