carykh demonstrates a script that speeds up the silent parts of a video while leaving speech at normal speed, to condense lectures and similar footage. It later became the Jumpcutter tool.
Referenced as the origin of automatic silence-skipping video editing and as a comparison for similar tools.

Time code to the cliffnotes: this video Basically instead of speeding up the entire video by 2x for a speed review, he created a script with variable speeding, where the silent bits are speeded up much faster than the talking bits, which means that the end result is much shorter.
Reminds me of the tool presented in [1], which also shows some interesting applications. Apparently an improved version is now being sold on its own platform [2], but the original Python script is still available on Github [3]. [1] this video [2] [LINK] [3] [LINK]
A YouTuber (carykh) made a video where he explains an algorithm he made to automatically process lecture videos by speeding up, condensing and removing parts of the video. this video
