         Alright! I can see that I will have to teach you...

     Okay, so you might think: What the heck is APNG and what are the advantages of it?
           Let me begin with a brief explanation of what APNG actually is:

Messaggio originale di Professor McArtwork:

                            APNG (Animated Portable Network Graphics)

It's an extention to already existing PNG format that adds
a special option for images to be animated like GIFs are!

        Alright, so APNG is just PNG but animated... What's the big deal?
     It actually turns out APNG is a much, MUCH better format than the GIF format is!
          Now let's see the main differences between GIF and APNG formats:

         GIF

             APNG

• An old technology created in the late '80s mostly for web animation for weak Internet connections.
  
  
• Color palette reduced to max 256 colors (or max 255 colors + 1 empty), however this limit can be bypassed with a help of blocks: en.wikipedia.org/wiki/GIF#True_color.
  
  
• Notable noise while applying dithering which sometimes may be unpleasant.
  
  
• Doesn't support partial transparency. The pixels of the animation can either be rendered or not.
  
  
• Because of the limitations, GIFs can be really small in size.

• A new technology of the 21st century that extends the standard PNG format.
  
  
• The file extention is .png which makes it backward-compatible with a regular PNG format. Software unsupporting APNG can still open and treat it like a still PNG frame.
  
  
• True-color palette (16,777,216 colors) without a need to separate the animation into blocks as for GIFs.
  
  
• Supports partial transparency via the alpha channel. This lets you create "see-through-glass" effects.
  
  
• Because of the new possibilities, APNG can be much larger in size than GIF.

            First, render a PNG sequence...

           As you can tell, APNG animations work similar to GIF ones.
           That means it's a sequence of images that are swapping
            with a constant frame rate giving an illusion of movement.


      Our first step is rendering your After Effects project into a sequence of PNG images.

         Select the composition you want to render and press Ctrl+M.
         Click the text that says Output Module and choose the format as "PNG Sequence":
            After that, select the Channels option to "RGB + Alpha".




          Select the output path you want to put your sequence in
        and press the "Render" button located to the right side of the panel.

                    Second, convert the sequence to APNG...

            Now you have your PNG sequence ready to be assembled into an APNG animation.

       To compile an APNG file, download a pack called "APNG Tools":
                    APNG Tools[beta.shibe.host]


         Unpack all files and run the "APNG Renderer" app. A window will pop out:




        Open your folder with previously rendered PNG sequence, select all images
       and drop them into this white area that says "Input files (drop here)":




             Now we have to set the frame rate of the animation. There is a button
         that reads "Delays - All Frames". Click it. A new window will pop out:




    Now listen closely: Here's a lit-- I mean, there are two values that can be modified.
     Leave the first value always set to "1". No, don't touch that! The second value,
       it's "10" by default, is your desired frame rate. Simply change it to any value
            that matches the frame rate of your artwork or anything else.


  We're almost ready! Name your PNG file in the "Output file" and click "Make Animated PNG".
           Your destination file will be located in the same folder where your PNG sequence is located.

                  Disclaimer...

                 APNGs have tendency to render waaaaaaaay too long
                  so a lot of patience is requred!
