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.

About a year ago we started on spinning off PowerSync as a standalone product that is…

Hi HN! I made Beatsync, an open-source browser-based audio player that syncs audio with millisecond-level accuracy across many devices. Try it live right now: https://www.beatsync.gg/ The idea is that with no additional hardware, you can turn any group of devices into a full surround sound system. MacBook speakers are particularly good. Inspired by Network Time Protocol (NTP), I do clock synchronization over websockets and use the Web Audio API to keep audio latency under a few ms. You can also drag devices around a virtual grid to simulate spatial audio — it changes the…
