* **Split video by chapters**: Videos can be split into multiple files based on chapters using `--split-chapters`
* **Multi-threaded fragment downloads**: Download multiple fragments of m3u8/mpd videos in parallel. Use `--concurrent-fragments` (`-N`) option to set the number of threads used
* Thumbnail embedding in `mp4` is done with mutagen if possible. Use `--compat-options embed-thumbnail-atomicparsley` to force the use of AtomicParsley instead
* Some private fields such as filenames are removed by default from the infojson. Use `--no-clean-infojson` or `--compat-options no-clean-infojson` to revert this
* When `--embed-subs` and `--write-subs` are used together, the subtitles are written to disk and also embedded in the media file. You can use just `--embed-subs` to embed the subs and automatically delete the separate file. See [#630 (comment)](https://github.com/yt-dlp/yt-dlp/issues/630#issuecomment-893659460) for more info. `--compat-options no-keep-subs` can be used to revert this

* youtube-dl tries to remove some superfluous punctuations from filenames. While this can sometimes be helpfull, it is often undesirable. So yt-dlp tries to keep the fields in the filenames as close to their original values as possible. You can use `--compat-options filename-sanitization` to revert to youtube-dl's behavior
For ease of use, a few more compat options are available:
--no-hls-use-mpegts Do not use the mpegts container for HLS
videos. This is default when not downloading
live streams
+ --download-sections REGEX Download only chapters whose title matches
+ the given regular expression. Time ranges
+ prefixed by a "*" can also be used in place
+ of chapters to download the specified range.
+ Eg: --download-sections "*10:15-15:00"
+ --download-sections "intro". Needs ffmpeg.
+ This option can be used multiple times to
+ download multiple sections
--downloader [PROTO:]NAME Name or path of the external downloader to
use (optionally) prefixed by the protocols

between 0 (best) and 10 (worst) for VBR or a
specific bitrate like 128K (default 5)

--remove-chapters REGEX Remove chapters whose title matches the

--no-remove-chapters Do not remove any chapters from the file

**Tip**: If you are porting your code from youtube-dl to yt-dlp, one important point to look out for is that we do not guarantee the return value of `YoutubeDL.extract_info` to be json serializable, or even be a dictionary. It will be dictionary-like, but if you want to ensure it is a serializable dictionary, pass it through `YoutubeDL.sanitize_info` as shown in the [example below](#extracting-information)
