FFmPEG-this

FFmpeg, but you'll actually use it.
_{Professional video editing, AI tools, and downloads — all in an interactive CLI menu. No commands to memorize.}

Why This Exists

FFmpeg is powerful. FFmpeg is also this:

# Crop to 9:16 portrait
ffmpeg -i input.mp4 -vf "crop=iw*9/16:ih:(iw-iw*9/16)/2:0" -c:v libx264 -crf 23 -preset medium -c:a aac output.mp4

# Extract audio as MP3
ffmpeg -i input.mp4 -vn -acodec libmp3lame -ab 320k output.mp3

# Compress to 25MB for Discord
ffmpeg -i input.mp4 -c:v libx264 -b:v $(( 25*8192/$(ffprobe -v error -show_entries format=duration \
-of csv=p=0 input.mp4 | cut -d. -f1) ))k -pass 1 -f null /dev/null && ffmpeg -i input.mp4 -c:v \
libx264 -b:v ... -pass 2 output.mp4

# Add subtitles... good luck
