Davids048andClaude Opus 5.5 f571621ae7 [refactor]: move examples to generate(request) and from_config
Every example calls VideoGenerator.generate with a nested request instead
of generate_video keywords, and passes settings outside the from_pretrained
convenience keywords through VideoGenerator.from_config at their typed
paths. Each request and generator config equals what the keyword call built.

"A robotic arm, primarily white with black joints and cables, is shown in a clean, modern indoor setting with a white tabletop. "
"The arm, equipped with a gripper holding a small, light green pitcher, is positioned above a clear glass containing a reddish-brown liquid and a spoon. "
"The robotic arm is in the process of pouring a transparent liquid into the glass. "
"To the left of the pitcher, there is an opened jar with a similar reddish-brown substance visible through its transparent body. "
"In the background, a vase with white flowers and a brown couch are partially visible, adding to the contemporary ambiance. "
"The lighting is bright, casting soft shadows on the table. "
"The robotic arm's movements are smooth and controlled, demonstrating precision in its task. "
"As the video progresses, the robotic arm completes the pour, leaving the glass half-filled with the reddish-brown liquid. "
"The jar remains untouched throughout the sequence, and the spoon inside the glass remains stationary. "
"The other robotic arm on the right side also stays stationary throughout the video. "
"The final frame captures the robotic arm with the pitcher finishing the pour, with the glass now filled to a higher level, while the pitcher is slightly tilted but still held securely by the gripper."
