Veo 3.1 Lite

Lower-cost Veo 3.1 text-to-video generation with fixed 720p or 1080p output and short duration controls.

Model Overview

Veo 3.1 Lite is the lighter-weight Veo 3.1 video model on Fal. It turns a text prompt into a short video clip with synchronized audio, supporting 16:9 or 9:16 framing and 4, 6, or 8 second durations.

Best At

• Prompt-only short-form video generation.
• Lower-cost ideation when full Veo 3.1 is unnecessary.
• Quick vertical or horizontal clips for social and concept work.

Limitations / Not Good At

• Fewer control surfaces than the full Veo 3.1 family.
• 1080p currently requires an 8 second duration.
• Output is a short clip, not a long-form sequence workflow.

Ideal Use Cases

• Fast concept videos from a written brief.
• Storyboards, social snippets, and motion mockups.
• Early prompt iteration before moving to a higher-cost model.

Input & Output Format

• Input: required prompt; optional aspect_ratio, duration, and resolution.
• Output: generated video URI returned on response.

Performance Notes

• Pricing scales by selected resolution and output duration.
• This Lite variant is meant for cost-conscious iteration, not maximum control.
