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].

On the about page you mentioned that you raised instead of continuing on the bootstrapped path. What made you pull the trigger? My first impression when I checked out the landing page and product was: this is a perfect bootstrapped SaaS product idea to grow to meaningful ARR with a small team of 2-3 + some hired help for things like customer support.

[This is Julia, the cofounder/CEO] We bootstrapped for 8 months and grew to about 100k of MRR before raising money. I wrote a blog post about this decision https://www.kapwing.com/blog/why-we-decided-to-raise-money-f... . tl;dr is that 1) It's a competitive domain, so we felt we needed to grow our team quickly to stay relevant 2) There's a lot of technical challenges with video editing in the browser + cloud, so we n…

Awesome! Thanks for sharing. I personally believe big ambitions lead to a more interesting journey, as well as having the ability to have more impact at scale. Impressive MRR!

Earlier quoted context omitted.

I think it's a gradient -- one extreme is that you have a recording with multiple takes and several long pauses as you're reading a script, in which case you want to streamline the clean up process. But I think it's a creative decision to make the cuts extremely tight and jumpy, not for everyone!

Or you have multiple camera angles and you switch between them to hide the cuts. Like they've done in movies forever. People started doing jump cuts in youtube videos and for some reason we're stuck with it.

>Or you have multiple camera angles and you switch between them to hide the cuts. Like they've done in movies forever.

Not exactly. Most movies use https://en.wikipedia.org/wiki/Single-camera_setup, so even though there might be cuts to different camera angles, each angle actually comes from different takes. The goal of different angles isn't really to cut out pauses/fillers, it's for stylistic/cinematography reasons.

>People started doing jump cuts in youtube videos and for some reason we're stuck with it.

Probably because setting up multiple cameras and lighting them is cost prohibitive for low budget videos on youtube?

If it's the type of video where cutting silence automatically is viable, I wish they would just write out the transcript. You can read what they're saying in a fraction of the time it takes to watch a video, and often internalize it better.

I think we'll display a transcript like this eventually, but I still believe the timeline should be the core driver of control

Weird. I edit a lot of videos but this is basically not something I have ever needed. The natural cadence of speakers is more valuable to me.

If you watch YouTube you'll notice there are lots of folks who edit out silences and disfluences. It really depends on what kind of video you're making :)

Congrats on the launch Shah! I can tell you stayed up late giddy for this launch :D. As another peer building for video creators, I am delighted to see more efficiency features like this released.

This approach was the one I tried first also (I also tried the frequency one fwiw, which has its own, worse drawbacks). But using loudness runs into issues if the source loudness isn't (relatively) even across the entire source media. Using a single sensitivity setting like this would be a problem if:

* recording gain is set to automatic, and there are sudden changes in noise floor like wind (if recorded in 24-bit or lower)

* crew adjusts gain partway through recording (big no-no but happens)

* talent/host moves in and out of microphone sweet spot

* talent/host adjusts themselves in a squeaky chair during silence or transition-to-silence (or coughs, or breaths loudly, or ambulance goes by...)

If you apply the edit w/ a single sensitivity and something like the above is true, it would cut in the wrong place. Unfortunately, you would have to watch the entire show, skipping to boundaries with your full attention to know that ever got a cut wrong.

I don't know if any other apps do this but there are plenty of Japanese youtube channels that do this This one in particular is the one where I was introduced to the style but it certainly wasn't the first to do this. https://www.youtube.com/c/%E6%9C%89%E9%9A%A3%E5%A0%82%E3%81%... To be clear, they aren't just cutting out silence, they are cutting them to the point that it's a style and the speech pattern, particular…
