GIF CONVERTER FULL
You can force the filters to focus the palette on the general picture ( full which is the default), only the moving parts ( diff), or each individual frame ( single). The palettegen and paletteuse filters have many additional options. So a value of 10 will cause the GIF to play 11 times. A value of 0 is infinite looping, -1 is no looping, and 1 will loop once meaning it will play twice.
Control looping with -loop output option but the values are confusing. split filter will allow everything to be done in one command and avoids having to create a temporary PNG file of the palette. Also see the Advanced options section below. 
These filters have many options, so refer to the links for a list of all available options and values.
palettegen and paletteuse filters will generate and use a custom palette generated from your input. The lanczos scaling algorithm is used in this example. scale filter will resize the output to 320 pixels wide and automatically determine the height while preserving the aspect ratio. 
A rate of 10 frames per second is used in the example.
This example will skip the first 30 seconds ( -ss 30) of the input and create a 3 second output ( -t 3). ffmpeg -ss 30 -t 3 -i input.mp4 -vf "fps=10,scale=320:-1:flags=lanczos,split palettegen paletteuse" -loop 0 output.gif Before you start it is always recommended to use a recent version: download or compile.
