A project can now be a clip: Setup has a Video switch with a length, a frame rate and presets that set the canvas too (Instagram story, reel and feed video, TikTok / YouTube Short, Square loop, Full HD clip). The preview renders the whole clip, shrunk to a memory budget, and loops it with play/pause and a scale; Save As... renders it again at full size and pipes the frames into ffmpeg as .mp4, .mov, .mkv, .webm or .gif, with a progress window that can cancel. --duration, --fps and --video-preset do the same from the command line. Effects learn about time through FrameTime and Effect::renderFrame, which falls back to render, so nothing that holds still changes. Channel split now sways, shakes and rolls a tracking bar down the picture in a video; its motion params are marked forVideo() and hidden in a still project, and a still renders byte for byte as before. renderFrames starts every frame from the same seed and renders the still stages ahead of the first moving one only once. The version moves to 0.6.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
