+- Video quality:
+    - Specify `-f bestvideo+bestaudio` to download the best video format and best audio format and (by default) merge them. This is the default, but only as long as "ffmpeg" is installed. If it's not installed and this option is not specified, it may instead download a lower quality format.
 - Download audio from video: `youtube-dl -c --extract-audio --audio-quality 0`
     - `--audio-format <format>`: Audio format, like "mp3", "wav", etc. Defaults to "best".

 - Common warnings and errors:
     - "*WARNING: Requested formats are incompatible for merge and will be merged into mkv.*": The best quality video and audio are different formats and will therefore be merged into an MKV file. This is completely fine.
     - "*ERROR: [...]: YouTube said: Unable to extract video data*": Try to open the video in an incognito browser to check what's up with it. If it requires you to log in, you may need to specify cookies and possibly your user agent. To specify cookies, log into a browser (Firefox or Chrome), export the cookies to file using the "cookie.txt" extension, and specify the cookie file for youtube-dl with the `--cookie <file>` option (see [How do I pass cookies to youtube-dl? (youtube-dl)](https://github.com/ytdl-org/youtube-dl/blob/master/README.md#how-do-i-pass-cookies-to-youtube-dl)).
