You also get localized editing, sharp text/interface rendering, and up to 12 reference inputs per generation.
- Unified Multimodal ContextA single run can combine 9 images, 3 clips, and 3 audio files, merging character, motion, camera direction, and sound into one seamless output.
- Built-in Stereo SoundEvery generated clip includes original soundtrack, speech, sound effects, and room tone locked to the visuals. It also supports voice transfer and voice cloning based on reference audio.
