If you make a lot of gifs and like to mess with a lot of values, it might make sense for you to do it graphically. Different source material calls for different settings, and I try to keep the final output as small as possible. Gifsicle -colors=256 -delay=4 -loopcount=0 -dither -O3 *.gif > animation.gifĪnd then tweak the parameters from there. Sometimes I cheat on the command line here, and just look at all the pictures with Preview or Image Viewer and delete the ones I don’t need.įinally, use gifsicle to wrap it all up into an animated gif.

Then go through and remove the images at the start and the end that you don’t want in the final gif.

In case you used any other format to output them, I use one line of imagemagick’s mogrify to convert them: You now should have a directory full of stills. You can put them into whatever directory you want of course.įor some reason the I don’t have the gif89a video output driver installed on my OS X computer, so I instead use png or jpeg in the place of gif89a up there. The next bit says to output gifs (that’s gif89a into the directory called “gif”.

-endpos is the end position of the clip, in seconds.

What follows is the H:MM:SS timestamp of the beginning of the clip you want. It’s set to null, because there’s no sound.

You’re just looking for a timestamp, so you can do this in any video player. Isolate the segment of video you want to clip out.

On Mac OS X, first install the Homebrew package manager, and then install these programs withīrew install mplayer imagemagick gifsicle

Sudo apt-get install mplayer imagemagick gifsicle On Ubuntu (or most anything Debian-based with large enough repositories - these are common programs) it should just be a matter of Make sure you have the programs installed. So I’ve worked out a process that uses the command line and requires only the programs mplayer, imagemagick, and gifsicle. But because I don’t always have access to a bunch of graphics software, and because I might be using my Ubuntu or OS X box, it’s nice to have a process that works with widely- and freely-available free software command line tools. Sometimes I see a few seconds of a video I’m watching and I think that it’d make a great animated gif. HOWTO: Create an animated gif from a video with command line tools
