YouTube lets you see 'most replayed' parts in videos

YouTube is rolling out an experimental feature to desktop and mobile users. The service will show you the most frequently replayed parts of the YouTube video you're watching. If the graph has a spike, this portion of the video has been replayed often. 

Video chapters can now also be auto-generated. And those using YouTube on smart TVs and gaming consoles can finally access the feature, which was first launched in May 2020. Video chapters break up videos into sections to make it easier to check out a specific part of the clip you might be interested in.
