Veo 3.1 Lite is the lowest-cost tier of Google's Veo 3.1, released in March 2026. It is prompt-only: image inputs are rejected, so every clip starts from text. Each request returns a fixed 8-second clip in 16:9 or 9:16 at 720p, 1080p or 4K, billed at a flat rate per generation. Prompts can be up to 4,000 characters. It is the simplest way to get Veo footage when you do not need frame control or reference images.

Best for

  • Generic B-roll and establishing shots
  • Testing Veo prompt ideas at low cost
  • Automated text-to-video pipelines
  • 4K background footage for web pages

Prompting tips

  • With no image input, describe the look fully: color palette, era, lens, time of day.
  • Every clip is 8 seconds, so plan an action that fills that time.
  • Set aspect_ratio: 9:16 for vertical platforms; the default is 16:9.
  • When you need to start from an image, switch to Veo 3.1 Fast.
