More accurate preview from sponsorblock by changing playback speed

Application

YouTube Revanced

Issue

To get more accurate preview when doing sponsorblock submission from YouTube revanced so it will make it easier for the contributors to make better quality segments while the users of sponsorblock get the benefits of better quality segments.

Patch

Let the user set custom playback speed value such as 0.85x, 0.80x or even better to any value.

Motivation

The preview from sponsorblock is not accurate.
When we set at normal playback speed or 1x, the preview you get is late while the opposite happen when the playback speed set at 0.75x. Based on that, the right value to get accurate preview must be higher than 0.75x but lower than 1x.

So by allowing users to set custom playback speed it is possible to get much more accurate preview that will result in better quality segment submissions and much more easier for contributors to make good quality segments that will improve users experience.

SponsorBlock already included a UI to go frame by frame. In combination with a slow playback speed why does this not suffice?

[Marjo-bae]

Sorry for late reply. While the frame by frame is more than enough for cutting visual change, when it comes to cut audio or speech, even at 0.75x playback speed is not enough.

Although the preview from sponsorblock when the video played at 0.75x is close to accurate it is still difficult to cut speech or audio precisely. Often times, after submitting the segment you have to check through browser such as Kiwi browser or Firefox to make sure whether the segment is good or not.

So by having more accurate preview it will help tremendously to cut audio or speech more precisely resulting in higher quality segments and easier process for the contributors when doing submission on mobile phone.
