It's tough because most web animation is traditionally done with the palette limitations of GIF in mind.

Web Entrepreneur 03/22/16 (Tue) 02:16:14 No.411

So how did you say i could reduce the palettte colors and also create lossy png or apng files? Preferably using GIMP but any method is welcome

I get that it beats the point to an extent but also it still is better than gif due to transparency handling

Web Entrepreneur 03/22/16 (Tue) 07:23:08 No.412

This is real easy in GIMP. Just go to Image -> Mode and switch the color profile to RGB and then back to Indexed. You'll be presented with a dialogue to choose how many colors you want to use and what kind of dithering if any. GIMP's APNG plug-in could be better though so you may need to export your image sequence and then assemble it with something else like apngasm.

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.

Web Entrepreneur 03/04/16 (Fri) 04:53:29 No.402

GIMP already has a modified libpng for APNG support which I'm guessing is probably the same thing that Gecko browsers use? On a Linux system I imagine you could just take one of those and put it in the proper directory. Might be trickier on a Windows system.

Although either way your image viewer is still going to need some code in it to actually make use of the libraries.

Web Entrepreneur 03/04/16 (Fri) 06:54:07 No.403

Some Linux distros already come with apng-patched libpng out of the box, mostly Gentoo- and Arch-based, maybe Mageia too. Not Ubuntu.

The problem is patched libpng only provides some additional functions, some new API. It can't force image viewers to call those functions.

So someone need to write new code for image viewers too.

mp4s and webms Web Entrepreneur 12/28/15 (Mon) 23:00:16 No.365 [Reply]

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.

I usually use the Windows GUI version but I think you may have the syntax wrong for the command line version. According to the sourceforge page you would do it like this, with a space instead of a slash between the two frame delay components:

apngasm 25.png 0*.png 1 25

Web Entrepreneur 12/31/15 (Thu) 15:32:54 No.375

I just realized I don't see any options for how to set the frame delay for a specific set of frames in the command line version of Apngasm. Seems like you have to set them all at once, whereas the GUI version lets you pick and choose.

Web Entrepreneur 01/03/16 (Sun) 02:32:41 No.376

I figured it out. Avconv does something fucky when it dumps the frames. I just tried again with another short webm and got the same laggy result. Then I ran the frames through GIMP before assembling the apng and it worked perfectly.

>I just realized I don't see any options for how to set the frame delay for a specific set of frames in the command line version of Apngasm.

If you have frame5.png and frame5.txt with delay=3/25 inside, that text will override the command line, but only for that particular frame.

If you specify 1 25 in the command line, all frames will have 1/25 sec delay except for 5th frame, it will have 3/25 sec delay.

Yeah that definitely doesn't make me want to use the command line version over the GUI version. I wish there was a GUI version for Linux instead of just Windows.

APNG plugin for GIMP krystal4lyfe!wE9OORZ9Gw 10/27/15 (Tue) 20:08:21 No.312 [Reply]

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

Unfortunately this plug-in (or GIMP itself) seems to still have some notable issues for APNG creation. One of which is that currently GIMP does not allow as fine of frame display control as is possible within APNG. Take a 60 FPS animation for instance. Converting this to frame display time, each frame should have 16.666… ms display. However, since GIMP's frame display only measures at the millisecond level, this must be rounded to 16ms or 17ms, creating some notable speed discrepancies.

Another option the APNG plug-in could really use is the ability to "use delay above for all frames", as the animated GIF export function has. This is useful for when you want to change the display time for all the frames in an animation at once.

Finally, it seems that you have to perform this Layer to image size step on every single undersized frame after optimizing the layers for differences or you end up with these annoying uncropped blank areas (that should be alpha channel transparency but aren't) on the margins of the undersized frames. Here's a comparison of an APNG assembled with apngasm and that same APNG opened with GIMP, optimized, and then re-saved with the APNG plug-in. I'm not sure why it's happening but additionally GIMP seems to be altering at least one of the colors in the process.

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.

VirtualDub usually doesn't make the most optimized GIFs or APNGs so that's where GIMP and other optimizing tools come in.

Well, as for the "JPEG is best for game screenshots" comment, that really depends on the game. If you're talking about a 2D game chances are very high that PNG is going to provide the superior file size in addition to being lossless. It's a matter of how objects are colored and animated that gives PNG the edge. If it's a 3D game though then yes JPEG will usually get the point of the image across the same while saving a lot of space. In a 3D game the colors of something from frame to frame can differ much more radically due primarily to lighting systems.

It is actually possible to do lossy PNG however, so JPEG may not be better in as many situations as one might think.

http://pngmini.com/lossypng.html

How all this relates to animated PNGs is that you're going to have a big file if you try to animate something with a lot of colors and little consistency between frames. A genuine video format like WebM, MP4, AVI, etc. is basically the animation equivalent of JPEG.
