How did you animate that before-and-after image?

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.

# 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))
