The procedure for creating a set of Ferret gif images would be the same see the documentation of gifsicle or other tools for how to use them to create the animation.ġ. One such tool is gifsicle, free unix-based software that works well for creating animations from a set of gif images. NOTE: In order to properly display, it is necessary to have backing store enabled for the Xserver.ĥ.1.2 Note on using a set of gif images to make a movieĪn easy way to make movies from gif files using third-party tools to generate an animation from a set of gif (png) images. Ye s? repeat/l=1:12/animate/loop=5 (shade sst go fland) Given LOOP=n, the entire animation sequence will repeat n times. In a Ferret session, display an animation with the command, yes? REPEAT/ANIMATE NOTE that starting with Ferret v6.6 HDF movies are no longer available. A series of gif images can also be animated, see Ch5 Sec1.2 below.įormerly we had a method using an HDF file type. One can animate "on the fly" in an interactive sesion, or a sequence of Ferret plots can be stored and then animated. To know more about how it works, you can check the repository.There are two modes for animating in Ferret. Video2gif video2gif -ts 10 -te 1:10 -s 400x200 -d 3 -fr 10 input.mpegįfmpeg + gifsicle ffmpeg -ss 10 -to 1:10 -i input.mpeg -s 400x200 -r 10 -f gif - | gifsicle -optimize=3 -d 3 > output.gifĪs you can see, it is not that hard to use ffmpeg+gifsicle, however, if you do this conversion frequently you may consider using my script. Set duration for each gif frameĭuration is defined by hundredths of a second, so 3 is equivalent to 0.03 second.įfmpeg + gifsicle ffmpeg -i input.mpeg -f gif - | gifsicle -optimize=3 -delay 3 > output.gifįewer frames generate smaller gifs, with the expense of making it choppier.įfmpeg + gifsicle ffmpeg -i input.mpeg -r 10 -f gif - | gifsicle -optimize=3 > output.gif Note: as in the previous example, argument position matters.

Default: 10.Įverything you do with video2gif you can do with ffmpeg and gifsicle. d, -gif-frame-duration delay/duration of each Gif frame in hundredths of a second. te, -end-time time position from video to stop gif. ts, -start-time time position from video to start gif. Those are all the options available in video2gif: video2gif However, if like me, you don't like to install random libraries and their dependencies in your main system, or maybe you just find this command too hard to remember, keep reading and I will tell you a bit more about it. If you are not interested in hearing about this tool, here is a simple command that does the job: ffmpeg -i -f gif - | gifsicle -optimize=3 > This script provides a set of options through a simple interface and, in case you don't have those libraries installed, it does everything inside a docker container. Some time ago I created a helper to convert videos to gif using ffmpeg and gifsicle.
