{{DISPLAYTITLE:{{spmono|vd}}}}
A very personal Windows Batch script for the downloading of videos from YouTube, Twitter (and maybe some other sources) to a local place (here in this case is <code>D:\<wbr />_<wbr />W<wbr />M<wbr />D<wbr />\</code>) using a locally stored up-to-date Net<wbr />scape-styled {{spmono|coo<wbr />kies<wbr />.<wbr />txt}} (here in this case, it is located at <code>D:\<wbr />Omni<wbr />gena<wbr />\<wbr />coo<wbr />kies<wbr />.<wbr />txt</code>) that automatically produced by {{spmono|yt<wbr />-<wbr />dlp}}. It requires the following software to be properly set up in {{spmono|%PATH%}} (here in my case is <code>C:\<wbr />_<wbr />c<wbr />\</code>):
* [https://github.com/yt-dlp/yt-dlp-nightly-builds/releases/latest/download/yt-dlp.exe {{spmono|yt-dlp}}]; and
* [https://github.com/yt-dlp/FFmpeg-Builds/releases/latest/download/ffmpeg-master-latest-win64-gpl-shared.zip {{spmono|ffmpeg}}].
By default, the script takes the input URL and tries to download the best matching video track of a resolution ''up to but not more than'' 4K with the best audio track it finds, merges them into one file using the suitable container that {{spmono|yt-dlp}} deems, and names the final output as ‘{{spmono|[yymmdd] title of the video (ID of the video).ext}}’, where ‘{{spmono|yymmdd}}’ in the square brackets of the beginning of the filename stands for a 6-digit date string converted from the timestamp, upload date, release date, or modified date of the video—whichever the source has defined and comes first, followed by the title of the video and then ends with the video’s ID wrapped in brackets. For most of the YouTube videos these days, this means it will return a filename similar to the one exampled below:
<div style="margin-left: 1.625em;">{{spmono|[241008] Visit the Falkland Islands—Stanley from the Skies (9gqvkyF-CDA).webm}}</div>
The ID of the video saved in the brackets of the ending part of the filename is pretty useful when it comes to videos downloaded from YouTube sources, where it can be put at the end of the following incomplete URL to recreate its source link; I cannot be certain, however, that this little trick is equally applicable on videos downloaded from other websites.
<div style="margin-left: 1.625em;">{{spmono|https<wbr />:<wbr />/<wbr />/<wbr />www<wbr />.<wbr />you<wbr />tube<wbr />.<wbr />com<wbr />/<wbr />watch<wbr />?<wbr />v{{=}}}}</div>
The script accepts switches listed as follows to control the maximum desired resolution of the video to be downloaded:
* <code>'''-l'''</code>: if applied, the script will remove all the resolution restrictions and try to download the best (highest) resolution of video it finds;
* <code>'''-m'''</code>: if applied, the script will try to download the video with the highest resolution that is ''under'' 4K;
* <code>'''-s'''</code>: if applied, the script will try to download the video with the highest resolution that is ''under'' 2K, which normally means ‘1080p’; and
* <code>'''-ss'''</code>: if applied, the script will try to download the video with the highest resolution that is ''under'' 1080p, which normally means ‘720p’.
Apart from these quality control switches, there is a special <code>'''-t'''</code> switch that is dedicated to Twitter video downloading, which, when applied:
* the naming pattern will change into ‘{{spmono|[yymmdd] display name of the Twitter user (UID of the Twitter user) Tweet ID.ext}}’, similar to the example shown below:<br />{{spmono|[241115] Sky News (SkyNews) 1857335821038211072.mp4}}
* a text file bearing the same name as the video will be saved alongside, in which the link to the Tweet, the full content of the Tweet, the timestamp of the Tweet’ publication, and the timestamp of the downloading of the Tweet’s video are recorded in the format of the example shown below:
<div style="margin: -0.5em 1.5em;">

</div>
* the saving location (of the video and the text) will be changed to a subfolder named <code>_twitter</code>; and
* the quality switches will be ignored since the resolutions of the videos on Twitter are normally low enough.
The script also accepts the following switches to append the main download command with their corresponding patches if applied:
* <code>'''-ws'''</code>: appends <code>--write-subs</code> to the main command;
* <code>'''-was'''</code>: appends <code>--write-auto-subs</code> to the main command;
* <code>'''-en'''</code>: appends <code>--sub-langs "en.*"</code> to the main command; and
* <code>'''-srt'''</code>: appends <code>--convert-subs srt</code> to the main command.
Lastly, if <code>'''-k'''</code> is applied, then the script will extract the video’s audio track and save it alongside in its original format, provided the current directory is writable—yes, the ''current path'', ''not'' the save location prewritten in the script, as an intermediate random file will first be written there and then be deleted shortly after.

When extracting the audio track using <code>-k</code>, its metadata will be stripped by default, unless the double {{spmono|k}} switch (<code>'''-kk'''</code>) is applied instead of the single one.

==The batch==

==The {{spmono|yt-dlp}} configuration files==
These files shall be put into <code>%<wbr />App<wbr />Data<wbr />%<wbr />\<wbr />yt<wbr />-<wbr />dlp</code> with no extension attached to their filenames.

==And a bash translation==
The following bash script is translated by ChatGPT 5.1. And since it is to be used on Linux, the configuration files above shall, then of course, be modified first (the paths, obviously) and then put into <code>~<wbr />/<wbr />.<wbr />con<wbr />fig<wbr />/<wbr />yt<wbr />-<wbr />dlp<wbr />/</code>.

There are some trivial differences between the following bash script and the above batch one; they are intended by design, and will therefore not be aligned in the future.

Both scripts use <code>'''-k'''</code> to extract the audio track, but on Linux, the metadata of the extracted audio track will be ''kept'' by default. Only when another switch, <code>'''-c'''</code>, is separately applied, will the script cleanse the metadata from the audio track. And, there is an added switch, <code>'''-a'''</code>, exclusive to the bash script, independent of and prioritised over <code>-k</code>, that, when applied, the original video will be deleted, leaving only the extracted audio track. (Still, <code>-c</code> is needed for the removal of metadata.)
