Only this structure is invisible to those who haven't watched the video yet. How will they know, for example, that the league starts at 30:00?
You don't need many timestamps, just for the main sections and Factions.
Timestamps solve the problem of a huge video because they allow you to break it down into several small parts, on a topic that interests a person.
For example, a person disagrees with a particular change and can quickly find arguments about it.

Thank you, Nargott and Uriel Septim X, for the constructive feedback about timestamps for the main sections. Now I think the arguments about the four-hour video review will no longer be valid. Everything can be found easily and quickly.

My friend, write the timestamps in the description of the stream, then people will be able to find the review of a Faction by the code (I would do it that way, but you have more experience, so decide for yourself).

Uriel Septim X, I went to your YouTube channel and, to my disappointment, didn't find a single timestamp under the videos. Some mod reviews don't even have a download link. Therefore, the statement "I would do it that way" is not applicable in this situation. If the channel owner does not indicate timestamps in their videos, they have no right to demand this from other channels. Once again, thank you for the idea of timestamps for key mod changes.

But a brief summary wouldn't hurt (and for more details, you can watch the video).

I wouldn't mind if you, as the forum administrator, watched the video and created a brief summary for everyone who wants it. They say that brevity is the soul of wit; unfortunately, I am not talented, but I think you, as the person who suggested this, know a thing or two about this difficult task. We would appreciate your help with this sensitive issue.
