Viko

What it does

Viko is a free, open source video editor that runs entirely in your browser. Unlike cloud-based editors, it processes everything locally with ffmpeg.wasm - your footage never leaves your device. It offers a frame-precise multi-track timeline with keyframe animation, color grading, chroma key, and captions, and fully offline MP4 export. No downloads, no accounts, no subscriptions, no watermarks. Projects and media stay in IndexedDB, making Viko the privacy-first choice for creators.

  Open-Source Video Editor Web App2024 · ▲588

  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…

  VidStudio, a browser based video editor that doesn't upload your filesApr 2026 · vidstudio.app · ▲301

  Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it. FFmpeg…

  Vididoo – Client Side Only Ffmpeg Video Editor2022 · vididoo.vercel.app · ▲20

  I revamped an old project I had done in Web Assembly (WASM) with the Media Bunny library, a JavaScript library for reading, writing, and converting video and audio files directly in the browser. Media operations are way faster and more performant. You can now easily perform operations like cut, merge, resize, and compress videos, extract or replace audio, blend tracks, add watermarks, control speed, crop, apply grayscale, and convert images to video, all running smoothly right in your browser.

  I made an open-source video editor2025 · github.com · ▲36

  It's an open source video editor designed for motion effects and versatility. developed with electronjs / TypeScript, FFmpeg, Litjs. I'm currently focusing on making it easier to edit long-form videos. Specifically, adding subtitles to podcast episodes or creating short-form content from YouTube videos. And I’m also developing several extensible utilities. For example, recording video with a floating webcam—similar to Loom—or using LLMs to make cut editing easier. To make all this possible, I believe the first step is to build a versatile, general-purpose video editor. Demo :…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
