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.

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
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.
