 - 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's geo restricted, try using a VPN or the [geo bypass options](https://github.com/ytdl-org/youtube-dl#geo-restriction). If it requires you to log in, you may need to specify cookies and your user agent. You may be completely out of luck.
