Video to ASCII Art
For whatever reason, I'm fascinated with ASCII Art. I guess it's because it reminds me of old school computing and hacking.
I was curious today if I could create animated ASCII Art from a video. It turned out to be pretty easy.
- Step 1*: I took a very short and simple video of myself on my phone. I took a video selfie and emailed that to myself.
- Step 2*: I used Adobe Premier, to convert the ~.MOV~ file from my phone into a series of ~.jpg~ files. Each frame of the video is being converted to a still frame.
- Step 3*: Each frame of the video is converted from a ~.jpg~ file to an ASCII art ~.txt~ file. I used an awesome tool called jp2a to do the conversion. This is the actual command I used to do the conversion.
jp2a
find . -type f | sort | xargs -I xxx jp2a --width=200 xxx --output=xxx.txt
- Step 4*: I then used ~cat~ to concatenate all of the text files and separate them with ~pre~ tags. At this point, I have a very simple html document with every frame of the animation inside of it.
- Step 5*: The last step here was to animate the frames.
(function() {
var pres = document.querySelectorAll("#images pre");
var len = pres.length;
for(var i = 0; i < pres.length; i = i + 1) {
pres[i].style.display = 'none';
}
var a = 0;
window.setInterval(function() {
pres[a].style.display = 'none';
pres[(a + 1)%len].style.display = 'block';
a = (a + 1) % len;
}, 40);
}());

The basic approach was to hide all but one of the ~pre~ tags. Then there is a timer that's running regularly to change which ~pre~ tag is showing.
You can see the final html document

- Step 6*: The last step here was to create a real gif. Since I don't know how to convert animated plain text into a gif, I just took a screen capture and rendered it as a gif. This is finale result:
