Made a config file at the same location where `youtube-dl` stores its.

~/.config/youtube-dl/config.yt-dlp:

    --restrict-filenames
    --output '%(title)s.%(ext)s'
    --ignore-errors
    --embed-subs
    --all-subs
    --format 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'
    --embed-thumbnail
    --audio-quality 0
    --add-metadata
    --xattrs
    --xattr-set-filesize
    --prefer-free-formats
    --geo-bypass
    --no-mark-watched
    --console-title
    --no-warnings
    --downloader aria2c
    --downloader-args '-j 16 -s 16 -x 16 -k 1M'

Only the last 2 lines are pertinent here but I am including my entire config because it serves me very well.

And my ~/.zshrc alias:

    alias ytdl="yt-dlp --config-location ~/.config/youtube-dl/config.yt-dlp"
