Generate a video
Generate a video. Choose the model with `model` (gemini-omni-1.1-flash by default, wan3.0-video, wan3.0-video-prime); resolutions and seconds depend on the model (see GET /v1/models, type video). A character can be given, also as @Name in the prompt; `reference_image` keeps a character, `first_frame` starts the video from an image (for storyboards), and `last_frame` with it sets the final frame. Returns 202 with an id; poll the status. AP is reserved at the start and returned in full on failure.
