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. 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)

...Ahh, I was confused because I would click on the image and didn't see any animation! What I did not realize was that I was seeing a JPG "thumbnail!"

This flipping effect is a good demo technique! Will make a note of it!
