01overview
What is Veo 3.1 Lite?
Veo 3.1 Lite is Google's lightweight tier of the Veo 3.1 family and the cheapest video model on Prospolabs. It generates up to 8 seconds per run across text-to-video and image-to-video, with native audio and best-in-class lip sync included at no extra cost. It's built for volume: short social clips, previews, and automated media pipelines where you ship many generations per day without watching the meter.
On Prospolabs you pay per generation in plain USD — no tokens, no subscription, no audio surcharge. Veo 3.1 Lite is $0.03/sec at 720p (retail $0.05/sec) and $0.048/sec at 1080p (retail $0.08/sec), roughly 40% under typical retail. An 8-second 720p clip is $0.24; an 8-second 1080p clip is $0.384. Top up from $5 and the same price applies whether you generate from the Prospolabs UI or the API.
Because Lite keeps Veo's synchronized audio and lip sync in a single call, you get talking-head and dialogue clips without bolting on a separate voice or sync step. When you need higher resolution or more headroom, Prospolabs lets you graduate to Veo 3.1 Fast or full Veo 3.1 using the same account and the same pay-as-you-go billing.
The cheapest video on Prospolabs — audio included
Veo 3.1 Lite is the lowest-cost video tier on Prospolabs: $0.03/sec at 720p (retail $0.05/sec) and $0.048/sec at 1080p (retail $0.08/sec) — about 40% off, with native audio and best-in-class lip sync at no extra charge. An 8-second 720p clip costs $0.24 and an 8-second 1080p clip costs $0.384. There are no tokens and no subscription; you pay per generation in USD and top up from $5. Same price in the UI and the API, and failed runs are auto-refunded.
02capabilities
What Veo 3.1 Lite can do
Text-to-video (T2V)
Describe a scene, action, and style in a prompt and Veo 3.1 Lite renders it as video. Use mode "text" with model id veo-3-1-lite. Pick duration 4s, 6s, or 8s, 720p or 1080p, and a 16:9 or 9:16 aspect ratio for landscape or vertical feeds.
Image-to-video (I2V)
Supply a starting frame and Veo 3.1 Lite animates it with motion, depth, and ambient context while staying faithful to the source image. Set mode "image" — ideal for turning product shots, characters, or stills into short motion clips.
Native audio with best-in-class lip sync
Audio is generated in the same call as the video — dialogue, sound effects, and ambient sound synced to the visuals, with Veo's best-in-class lip sync. On Prospolabs the price is identical whether audio is on or off, so there's no penalty for sound.
Tight control parameters
Steer output with duration (4s/6s/8s, max 8s), resolution (720p/1080p), aspect_ratio (16:9 or 9:16), negative_prompt to exclude unwanted elements, and seed for reproducible results across runs.
Built for high volume
Lite is the lowest-cost video tier on Prospolabs, so batch generation, A/B variants, and automated pipelines stay cheap. Failed runs are auto-refunded, so wasted spend on errors is zero.
03use cases
What people build with Veo 3.1 Lite
Short-form social at scale
Generate vertical 9:16 clips for feeds and stories at 4–8 seconds each. At $0.24 per 8-second 720p clip on Prospolabs, you can produce dozens of variants for a few dollars.
Talking-head and dialogue clips
Best-in-class lip sync plus synchronized audio in one call makes Lite a fit for narrated explainers, character lines, and avatar-style content — without a separate text-to-speech or sync pass.
Product and image animation
Drop in a still via image mode to bring product photos, mockups, or concept art to life as short motion clips for ads, listings, and landing pages.
Previews and drafts before upscaling
Use Lite to iterate cheaply on prompts and timing, then re-run the winner on Veo 3.1 Fast or full Veo 3.1 when you want higher resolution for the final cut.
Automated media pipelines
The async submit-poll-download API and per-generation USD pricing make Lite easy to wire into templated, high-throughput systems that generate clips on demand.
