Bulk converts movies for my jellyfin server. Converts them all into a universal h.264 mp4 aac web format that should (theoretically) run on any device. It accepts any FFMPEG-capable format, and it will automatically skip conversion if the output file already exists, to save time.

jellyfinConversion.sh

#!/bin/bash

shopt -s globstar

src_dir="MoviesSource"
dest_dir="Movies"

mkdir "$dest_dir"

for f in "${src_dir}"/**/*.*; do
    name=${f##*/}
    ffmpeg -n -i "$f" -c:v libx264 -preset slower -pix_fmt yuv420p -movflags faststart -c:a aac -ar 44100 -b:a 256k -f mp4 "${dest_dir}/${name%.*}.mp4"
done

This script is EXTREMELY slow. I made this for my own purpose to create high quality web-ready videos. I do not recommend using it unless you have a small library / a very powerful PC.

If you can avoid using it, do so.

Do not use this for non-english shows. Im working on a separate script for remuxing anime
