Izmanto `video_url` un `prompt` un ģenerē turpinājumu no `num_frames` kadriem (9 līdz 481). Neobligāts `end_image_url` nosaka, kur beidzas paplašinājums. `match_input_fps` saglabā avota kadru ātrumu, `generate_audio` pievieno skaņu, bet `video_size` noklusējuma vērtība ir auto. Izvade var būt mp4, webm, mov vai GIF.
