WARNING: "-f mp4" selects the best pre-merged mp4 format which is often not what's intended.
Pre-merged mp4 formats are not available from all sites, or may only be available in lower quality.
To prioritize the best h264 video and aac audio in an mp4 container, use "-t mp4" instead.
If you know what you are doing and want a pre-merged mp4 format, use "-f b[ext=mp4]" instead to suppress this warning
