Niwo Render Everything · montageai bundle Build a Niwo short-video asset bundle from any content the user can provide—PDF, paper, URL, Word, chat, or a finished script. Finalize the narration with the user, download real images and B-roll, trim clips with ffmpeg, write content.json and manifest.json, then deliver a zip the user uploads to Niwo Video Studio (https://niwo.studio/video-studio) for rendering. Requires downloading files to local disk, shell access with ffmpeg and ffprobe, and zip. Use when the user wants to turn any material into a short video, or asks to gather footage and stills to match a narration.
