I don't believe <code>youtube-dl</code> alone will do what you want. However you can combine it with a command line utility like ffmpeg.

First acquire the actual URL using youtube-dl:

<pre><code>youtube-dl -g "https://www.youtube.com/watch?v=V_f2QkBdbRI"
</code></pre>

Copy the output of the command and paste it as part of the <code>-i</code> parameter of the next command:

<pre><code>ffmpeg -ss 00:00:15.00 -i "OUTPUT-OF-FIRST URL" -t 00:00:10.00 -c copy out.mp4
</code></pre>

The <code>-ss</code> parameter in this position states to discard all input up until 15 seconds into the video. The <code>-t</code> option states to capture for 10 seconds. The rest of the command tells it to store as an mp4.

ffmpeg is a popular tool and should be in any of the popular OS repositories/package managers.

<code>youtube-dl</code> supports passing arguments to the underlying postprocessor (tested with version 2017.08.27.1):

<code>
youtube-dl -x --postprocessor-args "-ss 00:13:00.00 -t 00:04:00.00" https://youtu.be/...

This is basically the same as doing the postprocessing with <code>ffmpeg</code> yourself after downloading the file first.

<h3>Native Way (YT-DLP)</h3>
<a href="https://github.com/yt-dlp/yt-dlp" rel="noreferrer"><code>yt-dlp</code></a>, the spiritual successor to <code>youtube-dl</code>, supports this w/ ffmpeg installed.
It will ONLY download the section of video you specify, good for low bandwidth or long videos!
<hr />
<h4>Fastest</h4>
It accepts timestamps or seconds:
<code>yt-dlp.exe --download-sections &quot;*6:02-6:22&quot;</code>
It will only download the section specified (to the nearest keyframe).
<hr />
<h4>Exact Key Frame</h4>
If you need exact start / stop times (albeit slower):
<code>yt-dlp.exe --download-sections &quot;*1:22:22-inf&quot; --force-keyframes-at-cuts</code>
<code>inf</code> means to the end of the video.
<hr />
<h4>Sections</h4>
Download a section titled <code>&quot;03. Symphony No. 6, Op. 68 (Pastoral): III. Allegro&quot;</code>:
<code>yt-dlp.exe --download-sections &quot;03.*&quot;</code>
<hr />
<h4>Multiple Sections</h4>
Download multiple sections:
<code>yt-dlp.exe --download-sections &quot;03.*&quot; --download-sections &quot;05.*&quot; -o &quot;%(title)s-%(section_title)s.%(ext)s&quot;</code>
<hr />
<h5>A Note About Speed</h5>
This method downloads and transcodes pretty slow.
It may be faster to just download the whole video and chop up w/ ffmpeg.
I would definitely use this method for very long videos or very short segments.

For all the lazy guys who don't want to use more than one command, do the following:
<pre><code>youtube-dl https://www.youtube.com/watch?v=MJD39Aja1Is --external-downloader ffmpeg --external-downloader-args &quot;-ss 00:00:10.00 -t 00:01:00.00&quot;
</code></pre>
You can now combine the options of <code>youtube-dl.exe</code> and <code>ffmpeg</code> like choosing the format, removing the video and cutting the audio file etc. (maybe cutting the video file and than converting to an audio file, whatever happens first)
<pre><code>youtube-dl -f 251 https://www.youtube.com/watch?v=MJD39Aja1Is -x --external-downloader ffmpeg --external-downloader-args &quot;-ss 00:00:10.00 -t 00:01:00.00&quot;
</code></pre>
Note: on HLS videos such as on Twitch, you will also need to add <code>--hls-prefer-ffmpeg</code> for this to work.

You can download from the start up to a point without downloading the whole thing and editing. That's half of what this question asks:

<blockquote>
 interrupt the download with <code>^C</code>
</blockquote>

<ul>
<li>I've only tried this with <code>mp4</code></li>
<li>won't work with separate video and audio, you need a format with both. By default ytdl often gets separate video and audio, then merges them. Use <code>-F</code> to see the formats available, and choose an <code>mp4</code> that has both. e.g. <code>-f18</code> or <code>-f22</code> are usually there.</li>
<li>you'll have to estimate from percentage downloaded (which isn't linear; the compression rate varies over time).</li>
</ul>

Yes. It's a hack.

Further question: if you do want the separate video and audio formats, could you download part of each separately (using <code>^c</code> as here), and then merge them manually? I don't think it willl work for some formats.

This is to add to all the answers that involve <code>--postprocessor-args</code>.
I have a work around to the problem pointed out by @antgiant, that <code>--postprocessor-args</code> is applied to each post processor, outlined here (<a href="https://github.com/ytdl-org/youtube-dl/issues/26863" rel="nofollow noreferrer">https://github.com/ytdl-org/youtube-dl/issues/26863</a>). This could cause your arguments to be applied more than once resulting in unexpected behaviours, such as cutting your video shorter than it should.
I would make a comment to the original answers but I don't have enough reputation for that. To work around this you must set up youtube-dl to use a default config file, and specify all post processes you'd like to apply to the video/audio but one other post processes to use in the command line with <code>--postprocessor-args</code>. The goal is that there is only one post process for <code>--postprocessor-args</code> in the command line, so that it is only applied once.
For example, my config file specifies the <code>--ffmpeg-location</code>, <code>--audio-format</code>, and <code>--audio-quality</code>. So that in the command line, I would only use <code>-x</code>.
<pre><code>youtube-dl -x --postprocessor-args &quot;-ss 00:57.50&quot; &quot;URL&quot;
</code></pre>
Of course, this would work with any post process in the command line, so long as there is only one, and that the rest is hidden in the config file. To make a config file simply make a folder in your %appdata% called youtube-dl and create a config.txt there with all your parameters.
This is my first post at Unix &amp; Linux Stack Exchange, please don't hesitate to point out any mistakes.

This will download a video from 0-1:22 (slightly differences can arise because of keyframes). It can also download whole videos, just omit the time interval in that case.

For example, download 10 seconds from <code>07:35</code> to <code>07:45</code>:
<pre><code>yt-dlp --download-sections &quot;*07:35-07:45&quot; https://www.youtube.com/watch?v=vidid

And based on speed it looks like it's not done in post.

Here a clean batch script that will do the job nicely,
it should be easy to port this to linux as well.
ffmpeg.exe and youtube-dl.exe should be somewhere in %PATH%,
or just add the full path to the both commands in the script.
<pre><code>@echo off
rem
rem Download a part of youtube video
rem
rem Parameters :
rem 
rem &quot;%1&quot; = quality, &quot;-f18&quot;, &quot;-f22&quot;, ...
rem &quot;%2&quot; = youtube video &quot;url&quot;
rem &quot;%3&quot; = starttime &quot;HH:MM:SS&quot;
rem &quot;%4&quot; = duration &quot;HH:MM:SS&quot; (to capture 1 minute 00:01:00)
rem &quot;%5&quot; = outputfile &quot;my-part.mp4&quot;

youtube-dl &quot;%1&quot; -g &quot;%2&quot; &gt; urls.tmp
rem read the first line of the file &quot;urls.tmp&quot; in the variable &quot;url&quot;
set /p url=&lt; urls.tmp
ffmpeg -ss &quot;%3&quot; -i &quot;%url%&quot; -t &quot;%4&quot; -c copy &quot;%5&quot;
del urls.tmp
</code></pre>
In linux you can use this command:
<pre><code>ffmpeg -ss &quot;starttime&quot; -i $(youtube-dl &quot;url&quot; &quot;quality&quot; -g) -t &quot;duration&quot; -c copy &quot;output-file.mp4&quot;
</code></pre>

I am using Ubuntu, and the <code>youtube-dl</code> command is working absolutely fine.

However, now I want to download only a portion a video that is too long. So I want to download only a few minutes of that video, e.g. from minute 13 to minute 17.

Is there any way to do that?

How to download portion of video with youtube-dl command?

我使用的是Ubuntu，youtube-dl命令运行得非常好。但是，现在我只想下载一段太长的视频。所以我只想下载几分钟的视频，例如从13分钟到17分钟。有什么办法吗？
