Seedance: direct with references

Use Seedance when you want to guide a clip with a mixture of text, images, video, and audio references.

Starter prompt:

Keep the subject identity and wardrobe consistent. Begin on a tight portrait, orbit left through the rain, then reveal the full dance pose. Natural body motion, cinematic lighting, no cuts, no text.

Google Flow: build a connected world

Use Flow when one character or location needs to remain recognizable across several shots.

Starter prompt:

Use the same astronaut in every shot. Move from the amber desert into the observatory, then finish at the blue shoreline. Match the suit details, lens language, and time of day.

Runway: control the camera

Use Runway when the source image is already strong and you mainly need a polished commercial camera move.

  • Open it: Runway
  • Best for: products, portraits, campaign shots, and clean image-to-video tests
  • Access details: Runway free-plan details
  • Free-plan note: the starter credits do not renew, and free video exports include a watermark

Starter prompt:

Slow clockwise orbit around the chrome sneaker. Keep the product shape perfectly stable. Controlled studio reflections, shallow depth of field, subtle lime light trail, premium commercial finish.

Pika: make the effect the hook

Use Pika for fast transformations, swaps, additions, and playful visual surprises that read quickly in a social feed.

Starter prompt:

The velvet chair bursts into glossy cherries and silk ribbons while the small robot reacts. Fast opening transformation, playful physics, crisp final composition, no camera shake.

Luma: make a still feel cinematic

Use Luma when the image has atmosphere, depth, fabric, water, weather, or environmental movement.

  • Open it: Luma Dream Machine
  • Best for: natural motion, cinematic scale, mood, and dreamlike scenes
  • Access details: Luma free AI video generator
  • Free-plan note: free outputs are watermarked and intended for personal, non-commercial use

Starter prompt:

Slow push toward the traveler across the mirror ocean. The translucent fabric moves in a gentle crosswind and reflects in the water. Moonlit haze, natural cloth physics, quiet cinematic scale.

The test that saves credits

Do not send five unrelated ideas into five tools.

  1. Choose one strong 4:5 image.
  2. Write one six-second motion idea.
  3. Generate three variations in the tool that matches the job.
  4. Keep the most stable result.
  5. Add names, captions, logos, and CTA text later in your editor.

Always ask the video model to preserve subject identity, product shape, composition, and color. Add only one camera move and one environmental motion per test.
