def on_queue_update(update):
    if isinstance(update, fal_client.InProgress):
        for log in update.logs:
           print(log["message"])

result = fal_client.subscribe(
    "fal-ai/vidu/q2/video-extension/pro",
    arguments={
        "video_url": "https://storage.googleapis.com/falserverless/model_tests/video_models/output-3.mp4"
    },
    with_logs=True,

const result = await fal.subscribe("fal-ai/vidu/q2/video-extension/pro", {
  input: {
    video_url: "https://storage.googleapis.com/falserverless/model_tests/video_models/output-3.mp4"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
