Tietoja: LTX-2.3 22B · Extend Video
Ottaa `video_url`-osoitteen ja `prompt`-kehotteen ja generoi jatkon, joka sisältää `num_frames` ruutua (9–481). Valinnainen `end_image_url` määrittää, mihin jatko päättyy. `match_input_fps` säilyttää lähteen kuvataajuuden, `generate_audio` lisää äänen, ja `video_size` on oletuksena auto. Tuloste voi olla mp4-, webm-, mov- tai GIF-muodossa.
