Excels at

  • Clip lengths up to 15 seconds — longer than the Veo family allows
  • Optional native audio, priced separately from silent generation
  • Reference-to-video for subject consistency across shots

Signal

Use when

  • Longer narrative shots that would need stitching on other models
  • Sequences reusing a consistent character or product
  • Cinematic motion where clip length matters more than raw speed

Avoid when

  • Quick cheap drafts — Veo 3.1 Lite is far cheaper per second
  • Prompts written in languages other than Chinese or English
