Create the HD Animated GIF Generator

Make a new file called hd-gif and add the following text.

#!/bin/sh

## echo "USAGE"
## echo
## echo "./easy source.mp4 dest.gif FPS RESOLUTION"
## echo "./easy video.mp4 animated.gif 30 480"
## echo

inputfile=$1
outputfile=$2
fps=$3
res=$4
loop=""
[ -z "$5" ] || loop="-loop $5"
txt=$6
palette="/tmp/palette.png"
filters="fps=$fps,scale=$res:-1:flags=lanczos"
paletteops="stats_mode=diff"
paletteops=""
drawtext="
    drawbox=y=ih/PHI:[email protected]:width=iw:height=160:t=max,\
    drawtext=fontfile=/Library/Fonts/AppleMyungjo.ttf:\
    text='$txt':\
    fontcolor=white:\
    fontsize=60:\
    x=(w-tw)/2:\
    y=(h/PHI)+th"

ffmpeg -v warning -i $1 -vf "$filters,palettegen=$paletteops" -y $palette
if [[ -z "$txt" ]]; then
    ffmpeg -v warning -i $1 -i $palette -lavfi "$filters [x]; [x][1:v] paletteuse" -y $loop $2
else
    ffmpeg -v warning -i $1 -i $palette -lavfi "$drawtext,$filters [x]; [x][1:v] paletteuse" -y $loop $2
fi

Make Executable: chmod +x hd-gif

Now you can use your hd-gif script like this: ./hd-gif video.mkv anim.gif 24 480
