Kelvin-Helmholtz Instability

[edit]
Original - An animation of a Kelvin-Helmholtz instability arising at an interface between fluids of different densities and speeds
Movie Version - I converted the GIF animation (old tech, we should NEVER be using) to a video. The 5.3 meg file became 1.4 meg, much more friendly to people with slow internet connections and virtually the same quality.
Reason
Illustrates subject excellently and in an eye-catching manner

Comment I suggest you not make self-running GIF animations if you don’t like them. I’m thinking this is already the case. You seem like a programmer, who can get delight by shaving 300 milliseconds off someone’s download time. The present work-around to saving 300 milliseconds is to require readers click that play button. For some animations, that isn’t best. Someone needs to develop the self-running/looping ability for Theora videos and then I wouldn’t be digging in my feet on self-running GIFs. It’s not like I enjoy unnecessarily large files. In fact, I work mightily to reduce the file size of animated GIFs and use every trick in the book to do so. Like using 6-bit gray scale rather than 8 bits if I can’t really tell the difference.

BTW, I fixed the problem here (easily) with the self-running animation displaying properly simply by specifying its thumbnail at the native size of the animation: 479 pixels. The default “100000x260px” specification bound to create problems for a big animated thumb. Whether GIF or Theora, whichever is most desirable for a given use is up to a given editor’s preference, IMO. Personally, I keep all animations (GIFs and Theora) at 400 pixels, which is one of the default standards for Theora videos. Anything larger starts getting bit too large, IMHO.

I’m done here on this issue. I was not prepared to spend much of the day extolling the virtues and shortcomings of Theora, Flash, self-running animated GIFs, and other arcane technology. I was just pointing out that animated GIfs are officially approved for use on Wikipedia. They have their place. You don’t like them. That’s nice.
