Bug 449887

SUMMARY
***
YouTube chapters allow video creators to break their videos into sections. This helps with watch times and SEO (more on chapters here : https://support.google.com/youtube/answer/9884579?hl=en).

The format of video chapters can take on different forms, so long as they start with 00:00 and indicate the title of the chapter.

Example 1: 
1. Intro 0:00-1:08
2. Break it off 1:09-2:45
3. Cable of love 2:45-4:38
4. Flowers 4:39-5:50

Example 2:
00:00 - 00:34 | Intro
00:34 - 01:41 | Downloading the shared library file and importing to Penpot
01:41 - 02:24 | Quick overview of library file
02:24 - 03:22 | Importing the avataaars shared library in a Penpot file
03:22 - 04:04 | Overview of components


Typically, when I create chapters, I rely on the Guides that I created in Kdenlive and manually enter them in. That said, it would be great if there was an option in Kdenlive to automatically export chapters for YouTube. This could be done using the name of the guides as chapter titles and using the space between two guides as the duration, OR chapters could be created using the timeline's in-and-out points (similar to how you can save Timeline Zones in the Project Bin).


ADDITIONAL INFORMATION
***
In their 21.12 release, Shotcut introduced the chapters export in the format used to make chapters for YouTube: https://www.shotcut.org/blog/new-release-211221/

It is also possible to import and export chapter markers on Handbrake. Handbrake accepts chapter markers in .csv, .txt, .xml, and .tsv.
