Edit videos faster by automatically removing silences
Our team is filled with technologists and creators, and when we record and edit videos, 80% of the time is spent chopping up the video, removing silences, and picking the right takes. So we decided to build a tool that did that for you — or at least get you there most of the way! Our initial implementation is somewhat naïve and uses a user configurable silence threshold that just reads in volume levels. In the future, we’d like to use a frequency-based approach that focuses on the human voice. We’re also open to ideas, so let us know if you have any!

In plain words
This tool automatically removes silent sections from videos to speed up editing work. It uses a configurable volume threshold to detect and cut silences, reducing the manual chopping and organizing that typically consumes most of video editing time. The creators built it to handle a common workflow pain point for video producers and are planning to add voice-detection capabilities in future versions.

BeepThatOut2025 · beepthatout.com · ▲108Hi all, my friend and I have built an AI-powered (whisper) editor for youtubers, podcasters, and video editors, that should cut down manual editing time by a lot. It's 'a bit' more than just a whisper wrapper, because you can configure a lot: - what kind of profanities to filter - add your own words (i.e. 'covid') to prevent demonetization on platforms like youtube - adjust the transcript in the editor like in google docs - readjust the position of each word - use 1000Hz beep, silence, or your own sound and more. You can export your work as audio, video, or as an .xml project for popular…
Remove Silence from Videos with Ffmpeg2022 · github.com · ▲38There was recently a Show HN for a program that lets one remove silence from video files [0]. I was almost certain that ffmpeg could do this... But after searching for it, it turned out I was wrong: ffmpeg can't do this out of the box, and also can't read input from an EDL file [1]. So I set out to write a solution, as simple as possible: produce a list of select filters that are applied to video and audio, and retain only the non-silent parts. The 'silencedetect' audio filter detects silences, and produces timestamps for when silences start and end. So one can pipe the output of that to a…
