Multi-Track Non-Linear Timeline & Kdenlive MLT XML Interchange

Edit across multi-track video/audio lanes with ripple/roll/slip trimming, 12 keyframed visual/audio filters, and lossless Kdenlive MLT XML project import/export.

How it works under the hood: Verified by binary MP4/WAV/PNG/XML inspection gates (packages/platform-ssot & pnpm test:studio-io).

Overview

Browser video studio where you open your own clip, preview filters, save still frames and short clips, and search a subtitle file. A hosted processing service is in development.

Why it was built

Managing large video libraries usually means waiting minutes for media indexing, fighting fragile transcode pipelines, and jumping between separate apps just to compress, trim, upscale, or find a spoken quote.

Why it helps

Compresses, trims, joins and checks your own videos with nothing to install, and the files never leave your device.

What you can do

Live browser studio with a split-screen preview and instant clip export
Compress, trim, join, contact-sheet and loudness tools that run on your device
GPU upscaling, overlap splicing and scene indexing in private early access
