* VM is upgraded - we&#x27;re back :) *<p>Hi HN,<p>I love new web tech, and was excited to see ffmpeg ported to WebAssembly so decided to build a free tool that uses it to:<p>- Clip&#x2F;trim videos - Overlay text and images - Resize - Create GIFs or convert to a web-friendly MP4<p>All of this done in your browser, without ever uploading a file to a web server! (* Except Safari, it doesn&#x27;t support SharedArrayBuffers)<p>A little more:<p>I&#x27;ve been building a video creation app with my cofounder, and being a 2-man team, we wanted to think outside of the box on an &quot;eng as marketing&quot; strategy.<p>As a techy on a budget, ffmpeg.wasm sounded like the perfect library to make a powerful free tool without requiring a ton of server resources.<p>So we looked up some common tasks people want to do with videos and set out to build a quick tool to accomplish them.<p>I think there&#x27;s a ton more we can build into this - it&#x27;s been about a 2 week project, but thought it was cool enough to do an initial release now.<p>Hope you like it, and have suggestions on what we can improve!

Its amazing what we can do with modern browsers today.<p>Our app plug: 7 years back we did a quick tool to shrink JPG&#x27;s in browser (Again needs Chrome or Firefox) without uploading images to server: <a href="http:&#x2F;&#x2F;shrinkjpeg.com" rel="nofollow">http:&#x2F;&#x2F;shrinkjpeg.com</a>

Awesome idea, it is hard to try for now but it could be very useful. I especially like simple clip and resize feature but can&#x27;t try them right now...

Man I wish WebGPU would come soon so that we could get HW acceleration support for a lot of WASM projects.

&quot;Error establishing a database connection&quot; is what I&#x27;m getting. Hug of death?<p>EDIT: working again now, looks pretty cool!

&quot;You might have come across .mov while working with Apple softwares such as QuickTime, it was introduced in 1998 and uses a top secret compression algorithm. It is often quoted as the catalyst to Apple bringing feature length movie quality to their devices.&quot;<p>This description is absolutely killing me.

I made a similar thing last year that’ll take any gif you throw at it and make a Zoom background compatible video.<p><a href="https:&#x2F;&#x2F;donatstudios.com&#x2F;GifAsZoomBackground" rel="nofollow">https:&#x2F;&#x2F;donatstudios.com&#x2F;GifAsZoomBackground</a>

This is awesome - nice job!<p>Adding the ability to loop the gif back and forth would be great!

I remembered that WASM application cannot use any kind of hardware acceleration. So have anyone tested the website for large videos?

sounds cool. wonder in practice how this will work out with patent encumbered video formats.
