I have installed youtube-dl in my 14.04.

I can download video by following command,

$ youtube-dl [youtube-link]

But I want to know how to select available pixel quality of youtube video(i.e 1080p, 720p, 480p, etc).

In software description they said it's possible(shown in image below), but how to do..

    The description above is obsolete. From the man page: "youtube-dl now defaults to downloading the highest available quality as reported by YouTube, which will be 1080p or 720p in some cases." – Jos Jun 21 '14 at 10:08

    Note that YouTube has employed some sort of protection that prevents downloading tools from downloading (or even seeing) the 1080p version, but you can still download all other resolutions up to and including 720p. – thomasrutter Oct 1 '14 at 3:19
  • I know I'm a little late to the party, but here's my experience: askubuntu.com/a/1097056/327339. Use the -f best option. – Gabriel Staples Nov 29 '18 at 17:50

To download a video, you type the URL after the command like so:

youtube-dl 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

To select the video quality, first use the -F option to list the available formats, here’s an example,

youtube-dl -F 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

Here’s the output:

22          mp4       1280x720    (best)

The best quality is 22 so use -f 22 instead of -F to download the MP4 video with 1280x720 resolution like this:

youtube-dl -f 22 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

Or optionally use the following flags to automatically download the best audio and video tracks that are available as a single file:

youtube-dl -f best 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

If you encounter any error during the muxing process or an issue with the video quality selection, you can use one of the following commands:

youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio' --merge-output-format mp4 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

or as Gabriel Staples pointed out here, the following command will typically select the actual best single file video quality resolution instead of video quality bit-rate:

youtube-dl -f best 'http://www.youtube.com/watch?v=P9pzm5b6FFY'

These commands will ensure you download the highest quality mp4 video and m4a audio from the video as a single file or will merge them back into a single mp4 (using ffmpeg in my case). If ffmpeg or avconv is not available, youtube-dl should fall back to the single file -f best option instead of the default.

    Make sure that you do not choose DASH. That will be unplayable! – xyz Sep 13 '14 at 4:21

    I meant DASH Video. I tried to download 4K, but that's all in DASH format (DASH allows youtube to preserve bandwidth). It's radically different it will mostly be unplayable. – xyz Sep 24 '14 at 19:41

    @prakharsingh95 Yeah if anything you might be able to view the mp4 using VLC as VLC allows you to sync the video with a separate file for audio. I haven't tried it though. Have you tried converting the mp4 file from the DASH download to avi format? I think they are similar. – mchid Sep 25 '14 at 5:05
  • 2
    Yes. Dash is of course playable, but you need to mux the streams with something like avconv. Too slow for 4K. – xyz Sep 29 '14 at 8:39

    @AjayKumarBasuthkar Wow, that is an ancient version of youtube-dl. I'm surprised it actually even works! I usually recommend sticking with the Ubunttu repositories for software but for youtube-dl it is almost essential to have the latest and most up to date version. (see next comment) – mchid Jan 26 '16 at 23:48

You can download 1080p using youtube-dl, but you need to do a little extra work. Usually it will only download 720p as its max even if you can see 1080p on youtube.com.

Run with -F to see available formats:

youtube-dl -F https://www.youtube.com/watch\?v\=-pxRXP3w-sQ

171         webm      audio only  DASH audio  115k , audio@128k (44100Hz), 2.59MiB (worst)
140         m4a       audio only  DASH audio  129k , audio@128k (44100Hz), 3.02MiB
141         m4a       audio only  DASH audio  255k , audio@256k (44100Hz), 5.99MiB
160         mp4       256x144     DASH video  111k , 12fps, video only, 2.56MiB
247         webm      1280x720    DASH video 1807k , 1fps, video only, 23.48MiB
136         mp4       1280x720    DASH video 2236k , 24fps, video only, 27.73MiB
248         webm      1920x1080   DASH video 3993k , 1fps, video only, 42.04MiB
137         mp4       1920x1080   DASH video 4141k , 24fps, video only, 60.28MiB
43          webm      640x360
18          mp4       640x360
22          mp4       1280x720    (best)

notice that youtube-dl has labeled the last option 1280x720 as the 'best' quality and that's what it will download by default, but that the line starting with 137 is actually higher quality 1920x1080. Youtube has separated the video and audio streams for the lines labeled DASH so we also need to pick the highest quality audio which in this case is the line starting with 141. Then we run youtube-dl again this time specifying the audio and video:

youtube-dl -f 137+141 https://www.youtube.com/watch\?v\=-pxRXP3w-sQ

and it will download the 1080p video and auto-merge it with the highest-quality audio. It should also auto-deleted the separate downloaded parts. This method is a little extra work, but will get you the best results.

    thank you very much, didn't know about 137+141 – whitesiroi May 5 '15 at 14:48

    Your example and others present easy choices for the audio - that is, for high quality, choose the one with highest bitrate value. I recently however found myself faced with a choice between DASH audio , opus @160k or DASH audio 126k , audio@128k (44100Hz), 1.79MiB or DASH audio 127k , m4a_dash container, aac @128k (44100Hz), 1.94MiB. I had to choose but am uncertain about quality, or perhaps compatibility. – user643722 Jun 10 '15 at 12:13

    The best thing about youtube-dl is that it is multi-platform. This solution doesn't just work on Linux, but also on Mac and Windows. Thank you! – Antony Jun 2 '16 at 23:19

    Nowadays this is the default, but only if you have avconv (libav) or ffmpeg installed to do the file conversion. For Windows, you want to set --ffmpeg-location in %APPDATA%\youtube-dl\config.txt to the directory where avconv/ffmpeg is installed. If you've got a low-end system you might want -f bestvideo[fps<=30]+bestaudio in there as well, to avoid 60fps video. – GreenReaper Apr 6 '18 at 22:16
  • WARNING: You have requested multiple formats but ffmpeg or avconv are not installed. The formats won't be merged. – ACV Dec 10 '20 at 14:14

To select specific resolutions, you can specify the size and audio quality so they get selected automatically - so for 480p:

-f 'bestvideo[height<=480]+bestaudio/best[height<=480]'

with bestvideo[height<=720]+bestaudio/best[height<=720] for 720p etc. This can added to config file at ~/.config/youtube-dl/config (or even /etc/youtube-dl.conf) so you don't get oversized downloads:

mkdir ~/.config/youtube-dl
echo "-f 'bestvideo[height<=720]+bestaudio/best[height<=720]'" >> ~/.config/youtube-dl/config

You can use --ignore-config if you want to disable the configuration file for a particular youtube-dl run.

Please note that fairly often it will have to download a separate video and audio steam and merge them.

For more examples see youtube-dl's doucmentation.

    I had an issue where different segments of the same video had different format codes for the same resolution (e.g. hls-1476 for video 1 of 2 and hls-1665 for video 2 of 2 where both were 540p) so I couldn't just use "-f hls-1476" or "-f hls-1665" or I'd get "ERROR: requested format not available" Your command examples helped me retrieve what I wanted. – ssnobody Jan 22 '17 at 21:37

Some of the other options to download the best quality videos other than that mentioned here depending on your convenience is given below:

Download best mp4 format available or any other best if no mp4 available

$ youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'

Download best format available but not better that 480p

$ youtube-dl -f 'bestvideo[height<=480]+bestaudio/best[height<=480]'

Download best video only format but no bigger than 50 MB

$ youtube-dl -f 'best[filesize<50M]'

Download best format available via direct link over HTTP/HTTPS protocol

$ youtube-dl -f '(bestvideo+bestaudio/best)[protocol^=http]'

How to get the best video quality available.

This answer here, with the most votes, should be right to give you the best video quality available, but....it's not. bestvideo+bestaudio seems to choose only the best video and best audio of the options that are video only and audio only, then it merges the two together. Note that this also appears to be identical to the default behavior of youtube-dl. However, on the video I was looking at, the best quality was a single, pre-merged file that was already in a format with combined video and audio. The bestvideo+bestaudio option did NOT choose this best quality 720p file because it was looking only for separate video and audio files. Details below.

Solution? Have it grab the best single file which contains both video and audio in one instead, with this:

youtube-dl -f best https://youtu.be/FWGC9SqA3J0

In short: use the -f best option, NOT the -f bestvideo+bestaudio option!

Proof:

Notice that row 22 says "(best)" to the far right of it. This is the only option which offers hd720 quality, which is the best quality I can get when watching this video in a web browser on YouTube. It is the clearest and has the best definition. When I use either of the commands recommended by the top answer:

youtube-dl -f bestvideo+bestaudio https://youtu.be/FWGC9SqA3J0

OR:

youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/bestvideo+bestaudio' --merge-output-format mp4 https://youtu.be/FWGC9SqA3J0

I end up with a video that is both lower quality/lower resolution, and has a larger file size. I don't understand it exactly, but the -f best option is definitely the only one that truly gives me the best resolution.

Here's some screenshots from a tutorial video I was watching showing electronic circuit diagrams in the video. Notice how the latter one is much higher quality and more legible (click on each image and compare the tiny font in a zoomed-in view):

  1. Using the lower quality -f bestvideo+bestaudio option accepted here as the right answer (OR just using the default option: youtube-dl https://youtu.be/FWGC9SqA3J0):
  • enter image description here
  • Notice how fuzzy the icons are at the top, and how difficult to read are the open window and tiny words within it!
  • This is significantly worse than the quality I get when watching online at YouTube directly in the browser.
  • This option also takes up more memory for some reason: the video is 18.0 MB, and it took longer for my system to download and re-combine (audio + video) than the -f best option below, which only had to do one download and no recombining since it was already one file.
  1. Using the higher quality -f best option which I recommend:
  • enter image description here
  • Notice how much clearer the small icons at the top and small font in the window are!
  • This is the identical resolution to what I get when watching in the highest resolution possible directly in the browser on YouTube.
  • This option also takes up less memory for some reason: the video is 14.8 MB.

A bash wrapper script that prompts for the format, which includes all available renditions, including audio-only, video-only.

Accepts both absolute youtube URLs and video IDs.

#!/ usr/bin/env bash
# Download youtube video with desired quality

# youtube-dl accepts both fully qualified URLs and video id's such as AQcQgfvfF1M

url="$*"

echo "Fetching available formats for $url..."
youtube-dl -F "$url"
read -p "Please enter the desired format id: " FORMAT

## download the video
youtube-dl -f $FORMAT -g "$url"

## stream the video with mpv (no local file created)

I am a disk saver, so I download videos of the format 1280 x 720,
because 4k videos takes more size of my hard disk.
So I add youtube-dl in ~/.bashrc file like given below

Setting a work -

open terminal and type

  • nano ~/.bashrc
    now go to very bottom of the file and add given below command
  • alias yt='youtube-dl -if best'
  • save file by pressing Ctrl o then press Enter
  • exit file by pressing Ctrl x
  • and last run command source ~/.bashrc in terminal

Experiment -

Open terminal and type
yt https://www.youtube.com/watch?v=puPUJlV1-W4
It will start downloading video with the best quality.

Explanation -
Bash allows us to define aliases which act like shortcuts to bash commands
in our case we define alias as -
alias yt='youtube-dl -if best'
where yt is the shortcut command for 'youtube-dl' which gives relief
our fingers to type long command.
You can write anything at the place of yt.
I set a flag -i in youtube-dl -if best
which means

It will Continue on download errors, for example to skip unavailable videos in a playlist

Here is an explanation of streams/formats for anyone new to youtube-dl.

Some video sites, such as youtube, offer not only different resolutions of video to download, but have options in youtube-dl called formats to download video and audio separately. For the case of youtube, it will only offer the highest quality video and highest quality audio separately. Here's an example output of using -F flag to show all formats available:

So there's a lot of different formats, but some are labelled "audio only" or "video only". If I selected to download one of those formats by using the specified format code such as with -f 137, I would really get either an audio file or a video file with no audio, which is usually not what you want. If I had ffmpeg installed and specified both video and audio formats with -f 137+140, then youtube-dl would download video and audio and afterwards combine them together into one video file.

If you don't have ffmpeg installed, youtube-dl will by default select the highest quality format that has both audio and video. This maxes out at 720p (and is usually specified by format code 22 so you would download with -f 22). If you do have ffmpeg installed, youtube-dl will be able download the real best quality video (1080p or better if available) and best quality audio, and after downloading mux (combine) them together into one video file so this is what I recommend.

Summary: install ffmpeg and then you will be able to simply do youtube-dl [youtube url] without any flags to get the best quality video and audio automatically in one output video file.

youtube-dl's idea of best is not perfect. Take this example for instance :

The following command:

youtube-dl -f 137+251  https://youtu.be/Xj3gU3jACe8

produces far better results than this usage:

youtube-dl -f 18  https://youtu.be/Xj3gU3jACe8 (marked as best)

There seems to be further bugs as trying to specify the height filters to limit to 1080p doesn't work. It still downloads the 4k variant (which notably is not that marked as best either)

youtube-dl -f "bestvideo[height<=1080,ext=mp4]+bestaudio[ext=m4a]" https://youtu.be/Xj3gU3jACe8

  • Actually, the height filter works fine, you just got the syntax wrong. It's not [height<=1080,ext=mp4], but [height<=1080][ext=mp4]. Works like a charm here. – iGadget Jan 26 at 11:47
  • This is not the fault of youtube-dl but the best it can do with the formats provided if you do not have ffmpeg installed. See my answer. – qwr Feb 20 at 11:48
