Convert GIF to MP4 with script (linux)

How to turn ALL your .gif's in a folder into .mp4's.
Using ffmpeg and shellscript.
(does not remove .gif files)

Install ffmpeg

open terminal and use these commands

sudo apt-get update
sudo apt-get install ffmpeg

Create shell script

Create a new shell script file (just a text file that ends with .sh) in the folder where noita is saving the gifs, i named mine "gif-to-mp4.sh"

Here is the script, paste it into the shell script file, save it and run it with .gif files present in the same directory the script is in:


#!/bin/bash
for i in *.gif;
do name=`echo "$i" | cut -d'.' -f1`
echo "$name"
ffmpeg -i "$i" -crf 16 -pix_fmt yuv420p "${name}.mp4"
done



If you also want the terminal to not close after running the script and some pretty things like script outputting where it is being ran from then you can use my variant:



#!/bin/bash
echo "Script executed from: ${PWD}"
echo " "

BASEDIR=$(dirname $0)
echo "Script location: ${BASEDIR}"
echo " "

for i in *.gif;
do name=`echo "$i" | cut -d'.' -f1`
echo "$name"
ffmpeg -i "$i" -crf 16 -pix_fmt yuv420p "${name}.mp4"
done

echo " "
echo "Press ENTER to close terminal"
echo " "
read


(this of course works for any .gif, not just noita gifs)
(you can change -crf value to lower value for higher quality (max 4), or remove -crf parameter entirely and have .mp4 noita vids that each weigh at 500KB, but quality suffers)
