Mu LTX-2.3 22B · Extend Video
A’ gabhail `video_url` agus `prompt` agus a’ gineadh leantainn de `num_frames` frèam (9 gu 481). Bidh `end_image_url` roghainneil a’ suidheachadh far a bheil an leudachadh a’ crìochnachadh. Bidh `match_input_fps` a’ cumail ìre frèam an tùs, bidh `generate_audio` a’ cur fuaim ris, agus tha `video_size` auto mar bhun-roghainn. Faodaidh an toradh a bhith mp4, webm, mov no GIF.
