Reference-to-video and full video controls in the Studio
The Studio composer now exposes each model's real capabilities — reference images, keyframes, aspect ratios, resolution, duration, FPS, and audio.
- NewReference-to-video mode: guide a video generation with up to 5 reference images on models that support it (e.g. HappyHorse 1.1).
- NewKeyframe slots: video uploads are now labeled as start/end frames, so you can pin the first and last frame of a generation.
- NewPer-model video controls: aspect ratio, output resolution (720p/1080p), duration window, and an audio on/off toggle — each picker only shows what the selected model actually supports.
- NewFPS control (24/50) on LTX Fast, and durations up to 20 seconds where the model allows it.
- ImprovedThe API playground derives the same video knobs from each model's schema, so Studio and API stay in sync.
