Você pode escolher best e digitar

youtube-dl -f 22 http://www.youtube.com/watch?v=3JZ_D3ELwOQ

To get the best video quality (1080p DASH - format "137") and best audio quality (DASH audio - format "140"), you must use the following command:

youtube-dl -f 137+140 http://www.youtube.com/watch?v=3JZ_D3ELwOQ

Answer 3

De acordo com este comentário de glenn-slayden, um formato mp4 com o vídeo mais alto qualidade é obtida da seguinte forma:

I realize this thread is a bit old, but I think the situation has changed somewhat. For my goal:

• first and foremost always take the best available video quality regardless of format;
• but then never let the audio format alone cause you to lose mp4.

Previously, I was using bestvideo+bestaudio/best, but I find the following variant works much better for reducing mkv, (apparently) eliminating webm, but yet still guaranteeing the highest quality video (don't use the --merge-output-format option when using this):

--format bestvideo+bestaudio[ext=m4a]/bestvideo+bestaudio/best 

Notice that, in the first term, the ext filter is specified for the audio but not the video, a technique which I didn't see mentioned in the discussion above. If that seems backwards for my stated goals, that might be because, considering that we're trying to ensure that the video format is mp4, why is the constraint given for the audio?

The key is that each fallback term (separated by the slashes) will fail if any part of its requirement fails, moving on to the next term. When using bestvideo+bestaudio, many cases of getting a non-mp4 container only show up because that format selection unequivocally insists on bestaudio, which may then mean a mixed format. It's because the bestvideo+bestaudio command is too insistent that you get forced out of mp4.

But what if you care more about getting a mp4 container than you do about the audio quality? By insisting on m4a audio first--but then relenting on just that part while issuing bestvideo again--(by using the the format selection above) you essentially express a flexible preference for mp4 over the other containers; you surely do want mp4 if possible, but not at the cost of reduced video quality.

As I said, you may still get some mkv, but they will be greatly reduced in number and only used when required to supply a (supposedly) better video. And so far with this configuration, I haven't seen any webm at all, because something like 248+140 works ends up as mkv.

No último caso, adicionar --merge-output-format mp4 será convertido em mp4, se necessário. Então o comando completo é:

youtube-dl -format "bestvideo+bestaudio[ext=m4a]/bestvideo+bestaudio/best" --merge-output-format mp4
