I made this mostly to make content creation faster.

When recording a youtube video/ podcast. there's alot of downtime (silence) while looking at scripts or getting the correct item to display. So I made a webapp to automatically cut and stich the video back together then I can further edit in davinci resolve.

But I recently found out that this is crazy good for rewatching lectures or meeting recordings, No need to render, just drop the video in and watch it right away.

30min lecture can be watched in 12min!

I even added auto generation of subtitles to make studying lecture /meeting better.

Best of all everything runs locally, even the AI is running local models.

Hope HN finds this useful like it did for me!

Cool service, difficult to use website. On my iPhone random videos kept full screening as i scrolled down and the site was almost unreadable with Firefox dark mode on (I’m reading at night).

Ah I didn’t consider phone usage haha. Didn’t expect people to edit video using phones. It theoretically should work. But I’ll take a look and see if it’s fixable.

Might be less people using the tool on the phone and more folks discovering your site via socials etc. the homepage at least needs to be responsive.

Yea that’s a great point!

It should be mobile friendly now. I did do some quick tests. While the format support on mobile is super limited. It actually runs AI extremely efficient. Crazy how powerful phones gotten these days.

If it's 100% private as you state n your website, it would be opensource.

Not necessarily - if it works offline (without internet), that also satisfies the "privacy" requirement for many of us.

Not necessarily - software can collect data offline and then send a payload at a later time.

It definitely can! However that is easily verifiable. First is that. You can see in the network tab that nothing is uploaded Second is that you can just close the tab before enabling internet. It’s not possible to send payload if the webpage is gone.

Either way I’m not collecting video information. It’s gonna bankrupt me just on storage fees given how videos are so large

Funnily enough. It was open source. But I had to close it because it was getting in the way of my implementation velocity. I can always open source it again. But there’s a decent chunk of work to clean the code up with keys etc. Also when it was open source I got 0 PR it was mostly just ppl filing bugs which makes me think my audiences don’t really care, and I could just save time if close source it

I'm a bit confused, why is this 100% local web video editor asking for a login when exporting a video?

2 reasons!

Most important reason is to link membership.

Second is to prevent abuse for some of my features. Think of it like my poor mans recaptcha.

I can see why you were confused. Local in this case really meant there’s no uploading of videos. Render, editing, processing all done on your computer. Which also meant that speed of the app could vary depending on if you use it on your Apple Watch vs gaming pc. Hope that helps!

Hey, I've built a very similar tool aimed at creating shorts! Would love to potentially collaborate.

Cool! Link?

Is this lossless? Or does it re-encode the video (resulting in a loss of quality)?

Lossless! I think that was one of my biggest pet peeves on why lots of video editors would re-encode.
