Show HN: Open-Source Video Editor Web App
Hey everyone, for the past like six months I've been working on a portfolio project. I got tired of doing easy projects, so I decided to tackle something bigger and more challenging. That's when I came up with the idea of a video editor. This piece of work is intended to showcase my skills and land me a job, but I like to think when working on projects that my idea is so cool that people will like to use it, and I treat every project like a startup idea. Also I havent seen many open source video editors especially on web so that was one of the points why I decided to make that and not something else, but in the end its learning experience and im not expecting much if at all.<p>A bit about the video editor itself:<p>-website: <a href="https://omniclip.app/" rel="nofollow">https://omniclip.app/</a><p>-its free<p>-its open source (MIT Licensed)<p>-its using Webcodecs API for quick rendering<p>-works fully inside browser, client side, no private data is kept<p>-I made some readme with more details, im not expecting contributions but I added bit about it: <a href="https://github.com/aegir-assembly/omni-clip">https://github.com/aegir-assembly/omni-clip</a><p>Features:<p>-Trimming<p>-Splitting<p>-Supports - Text, Audio, Video (mp4) and Images<p>-Clip editing on preview - rotating, resizing, text styling and more<p>-Undo/Redo<p>-Render in different resolutions, up to 4k.<p>Things to know before using this editor:<p>-it is simple editor, but its my main project im working on and improving it.<p>-right now it only works with videos 25 fps and more but not less<p>-only 4 tracks -- its something I could improve quickly but forgot<p>-bug here and there (eg. filmstrip not rendering until timeline scroll moved)<p>-its not working on phones yet (drag and drop API problems)<p>I'd love to hear your thoughts and feedback on it.

Show HN: A web debugger an ex-Cloudflare team has been working on for 4 years
Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. <a href="https://jam.dev" rel="nofollow">https://jam.dev</a><p>It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create).<p>It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer wasn't sure if I meant that it returned an error or if it was unresponsive. So the engineer would be frustrated, I would be frustrated, and fixing stuff would slow to a halt while we went back and forth to clarify how to repro the issue over async Jira comments.<p>It’s actually pretty crazy that while so much has changed in how we develop software (heck, we have types in javascript now*), the way we capture and report bugs is just as manual and lossy as it was in the 1990’s. We can run assembly in the browser but there’s still no tooling to help a non-engineer show a bug to an engineer productively.<p>So that’s what Jam is. Dev tools + video in a link. It’s like a shareable HAR file synced to a video recording of the session. And besides video, you can use it to share an instant replay of a bug that just happened — basically a 30 second playback of the DOM as a video.<p>We’ve spent a lot of time adding in a ton of niceties, like Jam writes automatic repro steps for you, and Jam’s dev tools use the same keyboard shortcuts you’re used to in Chrome dev tools, and our team’s personal favorite: Jam parses GraphQL responses and pulls out mutation names and errors (which is important because GraphQL uses one endpoint for all requests and always returns a 200, meaning you usually have to sift through every GraphQL request when debugging to find the one you’re looking for)<p>We’re now 2 years in to the product being live and people have used Jam to fix more than 2 million bugs - which makes me so happy - but there’s still a ton to do. I wanted to open up for discussion here and get your feedback and opinions how can we make it even more valuable for you debugging?<p>The worst part of the engineering job is debugging and not even being able to repro the issue, it’s not even really engineering, it’s just a communication gap, one that we should be able to solve with tools. So yeah excited to get your feedback and hear your thoughts how we can make debugging just a little less frustrating.<p>(Jam is free to use forever — there is a paid tier for features real companies would need, but we’re keeping a large free plan forever. We learned to build products at Cloudflare and free tier is in our ethos, both my co-founder and I and about half the team is ex-Cloudflare) and what we loved there is how much great feedback we’d get because the product was mostly free to use. We definitely want to keep that going at Jam.)<p>By the way, we’re hiring engineers and if this is a problem that excites you, we’d love to chat: jam.dev/careers
