Maidir le LTX-2.3 22B · Extend Video
Glacann sé `video_url` agus `prompt` agus gineann sé leanúint de `num_frames` fráma (9 go 481). Socraíonn `end_image_url` roghnach an pointe ina gcríochnaíonn an síneadh. Coinníonn `match_input_fps` ráta fráma na foinse, cuireann `generate_audio` fuaim leis, agus bíonn `video_size` auto de réir réamhshocraithe. Is féidir leis an aschur a bheith mp4, webm, mov nó GIF.
