Here's my own video -> gif bash script: https://github.com/montanaflynn/vidtogif

And here's a one-liner using ffmpeg and ImageMagick:

  ffmpeg -i input.mp4 -vf scale=600:-1 -r 5 -f image2pipe -vcodec ppm - | convert - gif:- | convert -layers Optimize - output.gif

Careful, your script and one liner generates a whopping 1.5mb file for a 3s movie.

While gifify generates a 1mb file for a 800 px wide, 20s screencast.

https://github.com/pornel/giflossy helps a lot, and works with unix pipes too, you can try it.

Optimized! :)

Also, gifify has lots of options like compression, resizing, speed, colors..

Of course, in the end, it's only a wrapper to ffmpeg - convert - gifsicle (giflossy).

But it helps a lot in achieving MOVIE -> GIF. In a command line way or programmatic way (i.e., you can write a server that uses it and stream gifs to the client).

Yes I was just looking at your implementation and must say it's better in numerous ways :)

Why are you using that fork of gifsicle? I went to that repo to read the homepage but it was the unchanged gifsicle README.

It does implement support for lossy LZW compression which I assume he's using for this.

Yes giflossy does a very good job at compressing GIFs. Giflossy compression wlil be implemented in gifsicle in the end.

Next, take the Gifify output, upload to gfycat to get a optimised video file. Repeat until convergence.

I immediately thought of it too, it might be fun to do the movify to transform a gif to a movie, command line.

If you want to create a gif that represents the complete video in a short gif loop have a look at https://github.com/marlev/gifserver

"I spent hours googling for a service that creates an animated gif from a video, that represents the complete video. I only found solutions that animated the first 10 frames, the first 30 seconds etc. So i decided to create gifserverthat will represent the complete video with 9 looping frames,no matter how long the original file is."
