Key strengths

  • Use one prompt-only workflow when you want a quick text-to-video draft without preparing source media.
  • Upload one image for direct image-to-video generation, or multiple images when the prompt needs visual anchors.
  • Edit an existing video with a text instruction when you want to transform source footage without rebuilding the scene from scratch.

Best use cases

  • Character beats, atmospheric scene tests, short social clips, and visual storyboards.
  • Reference-heavy concepts where the prompt should point to several uploaded images with IMAGE_REF tags.
  • Fast video edit passes for creators who already have a source clip and need a directed transformation.

Prompt and workflow tips

  • For reference-to-video, insert tokens like <IMAGE_REF_0> and <IMAGE_REF_1> so the prompt clearly binds to each image.
  • Keep the action focused on one movement or edit instruction per generation.
  • Use video edit mode when the source clip already has the timing and composition you want to preserve.
