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 so…

this is super useful insight for us, thank you for sharing. yeah another product we're working on is "auto audio leveling", which I hope solves some of this, but we'll see.

and yes, I was very excited, thank you for checking it out, Van!

Isn't this a basic function in Audacity (for audio)?

in Audacity you can use Truncate Silence, which is pretty similar. Though obviously just for audio tracks, and I find it a missed opportunity that there isn't a live preview with a slider

I believe there is (or was) a product used by TV stations which would semi-automatically re-edit a movie to fit in a specific amount of time, mostly by removing the start of end of a cut where not much was happening on the audio or video. Assuming I'm not completely imagining that, anyone know what it's called?

The single-level approach is what Recut does too, and it tries to take a guess at a threshold with clustering but it's not always perfect. Maybe a better way to go would be a dynamic noise gate or kalman filtering or something.

Vidbase is looking awesome btw! I bet it's going to be huge. It looks like you've paid an insane amount of attention to the details.

Very nice! As someone who wrote a native tool to do pretty much this (Recut / getrecut.com) it's super impressive to see it done in a web browser. The editor feels very fast and fluid. Doing it natively was hard enough, and recently I've been rewriting Recut with Rust + Electron so I have an idea of how much work it was to get it working well :sweat-smile: Keep up the good work y'all!

Hi Dave, I just found out about your tool from this post and it looks amazing! I was about to download it to try it out but I'm now hesitant to try (and possibly later purchase) if it's being rewritten in Rust + Electron rather than a native Mac app. I wouldn't want to wake up one day and find a great native app has been replaced by an Electron app after paying $100 for it. Unless you were planning on Electron for Windows and keeping the Mac app native?

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.

I think it can depend a lot on the style you're going for, but also on what kind of video it is.

With multiple speakers at once, I think removing a lot of silence can make it sound pretty unnatural.

As a solo person speaking to a camera, or recording a screencast, when I'm not perfect out the gate (read: I repeat each line like 6 times), I've found it easiest to take a breath and leave a pause between each take. After that, the editing is pretty straightforward, just cutting out the silences and keeping the good takes.

Some people are super comfortable on camera and can just talk for a few minutes and it's done... or memorize a script and knock it out... but sadly I'm not one of those people. Even with upfront planning, I'm more like "record 45 minutes to make a 5 minute screencast" so removing silence automatically is a huge time saver.

Honestly the constant jump cut style of editing feels so unnatural to me... I'd rather watch someone takes pauses and not be taken out of the moment.... I'm sure this has applications particularly in advertising/marketing but it's not without outs issues.

Hey! The current plan is to offer both versions, at least until the Rust/Electron app is at feature parity with the Mac app. In any case, the Mac app will continue to work, and you wouldn't be forced to switch versions.

On the Rust/Electron side, all the heavy lifting is done in Rust-land, and so far, it's going pretty well. It's not all roses of course - it takes a bounce or two to start instead of launching instantly, and it seems there's not much to be done about Electron's baseline memory usage or size on disk.

(I went down a crazy rabbit hole of compiling Chromium/Electron to see if there were things that could be stripped out, because I honestly don't need much, but realized that is a very large undertaking. Possibly another day. Some kind of "Electron Lite" would sure be awesome...)

But in general I'm spending an inordinate amount of time paying attention to performance. It was my main concern with the Electron platform. So far I've got playback on par, and stuff like loading files, silence detection, and drawing waveforms is actually faster than the Mac version. It feels snappy.

I use final cut to edit videos. Two things I haven't figured out how to do is to automatically that I would love an automatic solution to:

1. Cross fade the audio between clips, without crossfading the video, if the sound is available past the cut point. I think its pretty much 90% of the time that I would want something like that.

2. I have clips from a gopro that had a selfie stick that made a loud clicky sound from rattling that peaks above regular audio. Some way to lower the volume on that clicky noise without having to manually go through and do it for each click.
