How to download YouTube Videos quickly

I used to use yt5s all the time to rip and remix videos:

now you have to use https://ytdlp.online/

…but it often downloads the functionally useless .webm extension. Like with other bullshit google extensions, you can simply rename from .webm to .mp4 and it may work - but twitter actually rejects it when you try to upload..

I also keep this flag around

yt-dlp -f "bestvideo[ext=mp4][height<=720]+bestaudio[ext=m4a]/best[ext=mp4]/best" YOUR_URL_HERE
