Luma Dream Machine Prompt Builder

Luma Dream Machine prompt builder

Luma Dream Machine shines when prompts describe believable physics and a clear camera move. This builder structures your idea into Luma’s preferred shape — subject, environment, physics descriptors, camera, and start/end hints — and produces a clean, copy-ready prompt.

How it works

The builder joins your inputs into a single cinematic sentence in the order Luma parses best:

subject + action with physics + environment + camera move + start→end hint + style

Luma’s differentiator is physical realism, so naming the physics (“the ball bounces with natural momentum”, “fabric drapes and sways”) gives the model concrete motion to simulate. The optional start/end hints describe the first and last beats of the shot to guide keyframe planning.

Tips for better Luma clips

• Name the physics. “Water cascades and pools” or “sparks scatter and fade” guides Luma far better than “cool effect”.
• One camera move. A single trajectory (orbit, push-in, static) keeps geometry consistent; combining moves causes warping.
• Describe the arc. Telling Luma how the shot starts and ends gives motion a direction across the clip.
• Keep it short and re-extend. Generate 5-second beats and use Luma’s extend feature rather than asking for one long, motion-heavy clip.
