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.
Why Hacker News points people here: Referenced as the origin of automatic silence-skipping video editing and as a comparison for similar tools.

“instead of speeding up the entire video by 2x for a speed review, he created a script with variable speeding”
Variable-speed script that speeds up silent parts of 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.

Algorithm to automatically condense lecture videos
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
“Reminds me of the tool presented in [1], which also shows some interesting applications.”
Earlier similar tool with interesting applications
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
