Show HN: Edit videos faster by automatically removing silences

#1

Post by shahahmed »

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!

Instead of cutting out the silence spots, why not speed them up? If the presenter is silent b/c they are drawing something on the board (like in a lecture), then the result will feel a choppy.

that's a good idea. we'll try adding that, but i still think there are a lot of situations of "dead air," like between takes or long pauses.

Whoa. For years I've been seeing YouTube videos that seem to just teleport choppily around what I assumed were silences. I always assumed there was a standard tool that everyone used to do this. I can do the equivalent thing to a podcast episode in like 5 seconds in Logic. The notion that people have been doing this by hand is staggering, but kudos to you for finally coming along and filling this niche.

Can I ask what tool / plugin you use to do this in Logic?

I'm pretty sure of seeing an ad for such a plugin more than 5 years ago. Is it now built in into most editors such as Final Cut Pro?
