What is the best quality audio and video from this Youtube video?
I would like to download a youtube video with the best video quality and audio quality.
Based on this answer, I would like to pick the best video and best audio, then merge them together.
However, I'm unsure which one will be the best choice.
The -F command gave me the following information
249 webm audio only DASH audio 54k , opus @ 50k, 8.60MiB
250 webm audio only DASH audio 68k , opus @ 70k, 10.98MiB
171 webm audio only DASH audio 123k , vorbis@128k, 19.82MiB
140 m4a audio only DASH audio 131k , m4a_dash container, mp4a.40.2@128k, 23.65MiB
251 webm audio only DASH audio 132k , opus @160k, 21.46MiB
160 mp4 256x144 144p 110k , avc1.4d400c, 30fps, video only, 6.48MiB
278 webm 256x144 144p 119k , webm container, vp9, 30fps, video only, 15.64MiB
242 webm 426x240 240p 219k , vp9, 30fps, video only, 16.57MiB
133 mp4 426x240 240p 275k , avc1.4d4015, 30fps, video only, 14.96MiB
243 webm 640x360 360p 409k , vp9, 30fps, video only, 25.87MiB
134 mp4 640x360 360p 520k , avc1.4d401e, 30fps, video only, 26.78MiB
244 webm 854x480 480p 749k , vp9, 30fps, video only, 37.32MiB
135 mp4 854x480 480p 975k , avc1.4d401f, 30fps, video only, 38.80MiB
136 mp4 1280x720 720p 1343k , avc1.4d401f, 30fps, video only, 52.98MiB
247 webm 1280x720 720p 1509k , vp9, 30fps, video only, 65.66MiB
17 3gp 176x144 small , mp4v.20.3, mp4a.40.2@ 24k, 13.90MiB
36 3gp 320x180 small , mp4v.20.3, mp4a.40.2, 41.49MiB
18 mp4 640x360 medium , avc1.42001E, mp4a.40.2@ 96k, 68.85MiB
43 webm 640x360 medium , vp8.0, vorbis@128k, 96.53MiB
22 mp4 1280x720 hd720 , avc1.64001F, mp4a.40.2@192k (best)
I assume
247 = best video available. However, I'm not sure what 1509k mean?
After selecting this, Mediainfo told me that the video has 477kb/s. Was I doing something wrong?

Please read the youtube-dl documentation:
By default youtube-dl tries to download the best available quality, i.e. if you want the best quality you don't need to pass any special options, youtube-dl will guess it for you by default.
Note that if you have a specific requirement regarding video and audio codecs or formats used, you should set the format:
You can also use a file extension (currently 3gp, aac, flv, m4a, mp3, mp4, ogg, wav, webm are supported) to download the best quality format of a particular file extension served as a single file, e.g.
-f webmwill download the best quality format with the webm extension served as a single file
YouTube will offer VP9-encoded video and Opus-encoded audio when querying a WebM format; these are the itags starting with a "2". As these are way more efficient (i.e., offer better quality at the same size) than the H.264- and AAC-encoded video and audio streams starting with "1", you could choose -f webm for any download.
Also, there are more options for querying the format.

I have read the document, but after checking the overall bitrate from the command without any option, the downloaded video was only 477kb/s, so I thought I did something wrong since -F tell me that there is 720p 1509k. Choosing 247 as a video also gave me the same result, Is this mean that 477kb/s cause from VP9?

The bitrate that is indicated by the-Foption is only a rough indication of the targeted bandwidth, but has little to do with the actual video bitrate that you get once you've downloaded everything. You can expect there to be huge variations. The 247 format should still be the “best" one in this case.

I have read the document, but after checking the overall bitrate from the command without any option, the downloaded video was only 477kb/s, so I thought I did something wrong since -F tell me that there is 720p 1509k. Choosing 247 as a video also gave me the same result, Is this mean that 477kb/s cause from VP9?

The bitrate that is indicated by the-Foption is only a rough indication of the targeted bandwidth, but has little to do with the actual video bitrate that you get once you've downloaded everything. You can expect there to be huge variations. The 247 format should still be the “best" one in this case.

@Albin Video: Highest possible resolution and bitrate Audio: Highest possible quality (I'm not sure if opus 160k and mp4a.40.2 192k is similar?)
