Subject motion
Prompting advice: Your text prompts can absolutely help drive the movement in a clip, but try to describe what's happening (e.g. "the dog runs across the field") rather than conversationally asking for motion ("e.g. please make the dog wag its tail"), as asking will fail to produce the motion you're looking for.
In-platform advanced controls: To make a specific in-shot element move with any Gen-2 prompting mode, try Motion Brush (video tutorial).
Camera motion
Prompting advice: Writing camera controls in your text prompt ultimately won't achieve what you're looking for, as text prompts largely dictate what a shot contains — you can imagine this as "what the camera is looking at" — rather than what the invisible camera "filming" your generation is doing. Thus, please opt for the below advanced controls to achieve camera motion.
In-platform advanced controls: To define a set camera motion for a shot in Gen-2, try Director Mode. While there's no current method to hold the camera totally still, a lower Single Value Motion value can often help keep the shot more steady than a higher value.
