I can't figure it out.

It's an Animated PNG created with AviSynth and VirtualDub APNG Mod. Below is the script I used, Loop=delay and AssumeFPS=speed, load the script and save to apng. I chose to to it this way because not all browsers support apng. If a apng is not supported by the browser (for example Chrome) then the user just get a side-by-side comparison. I could of used GIF but the quality is limited. Reel.Deal 19:39, 16 September 2015 (CEST)
# Single frame RGB32 source
o = last.Loop(25)
# Processing
o2 = o.ChannelMixer()
# Combine
Left = o.Subtitle("Before") ++ o2.Subtitle("After")
Right = o2.Subtitle("After") ++ o.Subtitle("Before")
Stack = StackHorizontal(Left, Right)
# Output
Return (Stack.AssumeFPS(30))
You can probably do more advanced stuff with APNG Assembler or APNG Anime Maker. I also used APNG Optimizer. Reel.Deal 19:55, 16 September 2015 (CEST)
