O modelu LTX-2.3 22B · Extend Video
Sprejme `video_url` in `prompt` ter ustvari nadaljevanje z `num_frames` sličicami (od 9 do 481). Neobvezni `end_image_url` določa, kje se razširitev konča. `match_input_fps` ohrani hitrost sličic vira, `generate_audio` doda zvok, `video_size` pa je privzeto nastavljen na auto. Izhod je lahko mp4, webm, mov ali GIF.
