Special Thanks

To Alex for figuring all this out in the first place and writing the script

#!/bin/zsh
set -xe
language=Turkish
model_size=large
filenamefunc () {
for file in input/*; do
echo "$(date) ---------- starting whisper ----------"
whisper --model $model_size "$file" --language $language --task translate --fp16 False
echo "$(date) ---------- starting ffmpeg ----------"
ffmpeg -i "$file" -vf subtitles="$(basename "$file")".srt output/"$(basename "$file" .mp4)"_engsub.mp4
done
}
cleanup () {
for file in input/*; do
rm -rf "$(basename "$file")".srt
rm -rf "$(basename "$file")".vtt
rm -rf "$(basename "$file")".txt
rm -rf "$(basename "$file")".json
rm -rf "$(basename "$file")".tsv
done
}
