Local video workbench for 2026
无极工具 Videos packs common media jobs into the browser: compress, trim, convert, screen record, plus GIF, mute, speed, rotate, watermark, merge, and audio/subtitle helpers.
Great for short-form repurposing, social prep, course recording and subtitle cleanup. Local-first by default for speed and privacy.
