PROMPT

"Make the enemies approach towards the man. The man standing, lifts his sword getting ready to fight them."

OBSERVATIONS

According to the prompt given to Runway ML Video Generator AI, the motion of the dragons flying and the army walking is perfect, showing how great Runway ML Video Generator AI is at motion physics and depth in the video.

Although Runway ML video generator AI fails at delivering the movement of the main character, which was to lift the sword, we cannot judge Runway ML too harshly for this, as it is very difficult for AI to handle such complex actions.

This example does show why Runway ML is used in real-world applications, such as in the production of the Oscar-winning film *Everything Everywhere All at Once* and segments for *The Late Show with Stephen Colbert*.

OBSERVATIONS

If you heard the above AI video result from Synthesia video generator AI, you must have noticed that the AI avatar said "coma" instead of treating it as a pause while speaking.
