Bash function to convert Video to GIF with ffmpeg

Just add this to your .profile or place it in some function script and source it.

video2gif() {   
    ffmpeg -y -i "${1}" -vf fps=${3:-10},scale=${2:-320}:-1:flags=lanczos,palettegen "${1}.png";   
    ffmpeg -i "${1}" -i "${1}.png" -filter_complex "fps=${3:-10},scale=${2:-320}:-1:flags=lanczos[x];[x][1:v]paletteuse" "${1}".gif;   
    rm "${1}.png"; 
}

There is no simple mnemonic to memorize when converting video, so it is clearly better to have this function somewhere to be able to use like:

video2gif input.mov
