Keep the MP4-to-animated-looping-WebP creator, export timeline edits as animated looping WebP, or compress a selected imported WebP while preserving looping animation with Light / Moderate / Heavy presets plus an auto-fit target.
Browser preview depends on the browser’s built-in decoders. This report shows what the browser claims it can play, plus a quick “did this file load?” probe.
Warcut Studio is a single-file, local-first editor mockup: import media, assemble a timeline, layer overlays (lower thirds + PNG), and export animated WebP with FFmpeg.wasm. It’s designed to be viewport-safe and run in a browser.
The preview viewport is your “workspace camera”. These controls do not change export — they help you see/align things.
