O modelu LTX-2.3 22B · Extend Video
Prima `video_url` i `prompt` te generira nastavak od `num_frames` kadrova (9 do 481). Neobavezni `end_image_url` određuje gdje završava proširenje. `match_input_fps` zadržava broj sličica izvora, `generate_audio` dodaje zvuk, a `video_size` prema zadanim postavkama je auto. Izlaz može biti mp4, webm, mov ili GIF.
