Video

Turn an image into a moving shot, or describe a clip from scratch. Video costs more than images, so it pays to set it up well.

Making a clip

  1. Open the Video tab, or press Animate under an image to bring it here as the start frame.
  2. Pick a model. The picker prices each one for the clip as you've set it up.
  3. Add a start frame (upload, or drag one from your gallery) and, if the model takes one, an end frame. Both are optional for most models.
  4. Describe the motion: what moves, how the camera moves, how it ends. The image already shows what things look like, so spend your words on what happens.
  5. Set the length and resolution, turn sound on if the model has it, and press Generate.
Video is priced per second; the line under Length spells it out. A clip costs far more than an image, so try a short, low-resolution or draft version first. Runs of 10,000 credits or more ask before they start.

Which model

  • P-Video: cheap and quick, with a draft mode. The default, and a good first try.
  • LTX-2.5: good value for animating a frame.
  • Seedance 2.0 and 2.0 Fast: keep characters consistent from up to 9 reference images, or use a start and end frame (not both).
  • Kling 3.0, and Kling 3.0 Omni, which combines up to 7 references with a start frame.
  • Veo 3.1 Fast: strong motion, with sound.
  • FLUX 3 Video: 5–20 seconds with sound, from text or a start and end frame.
  • Wan 2.7: needs a start frame.

Writing for video

  • One continuous moment: no cuts, no new characters arriving from nowhere.
  • Name the camera move (“slow push-in”, “static tripod”, “handheld drift”) and keep most shots calm.
  • Order the action: what happens first, then, and at the end.
  • Enhance rewrites your prompt the way the selected model reads best.
