Veo 3.1 Lite
Google · AI videoVeo 3.1 Lite is Google's cost-efficient video generation model, built for high-volume applications while still delivering strong visual quality and natively synchronized audio. It supports text-to-video, image-to-video, and smooth transitions when you provide both a start image and an end frame—making it a practical choice for YouTube Shorts, TikTok, and automated pipelines where cost per second matters.
Unlike the full Veo 3.1 tier, Lite omits some premium capabilities such as multi-reference “ingredients” guidance and video extension, and it does not offer 4K output. It remains a strong fit when you want dialogue, sound effects, and ambience generated together with the picture, without paying flagship rates.
VidMachine exposes Veo 3.1 Lite as a selectable video model in project settings so you can prioritize it for budget-friendly runs, pair it with full Veo 3.1 as a fallback, or mix it with other providers in your model priority list.
Key features and benefits
Native synchronized audio
Every output includes audio aligned to the visuals—speech in quotes, sound design, and environmental ambience—so short-form clips feel complete without a separate audio pass. Describing dialogue and sound in your prompt still yields the richest results.
Text-to-video and image-to-video
Generate from a detailed text prompt alone, or animate a start frame image with motion and audio guided by your prompt. Portrait 9:16 workflows match typical short-form social formats.
Start and end frame control
When you supply both a starting image and an ending image (last frame), the model can interpolate between them for smoother continuity across scenes—useful for continuous transitions in multi-scene projects.
720p and 1080p output
Lite supports 16:9 and 9:16 aspect ratios at 720p or 1080p. Note that 1080p requires an 8-second duration on the API; shorter clips use 720p so generation stays valid and cost-predictable.

Use cases and applications
Veo 3.1 Lite suits creators and teams producing many short clips per week: social posts, ads, variants for A/B tests, and automated batches where native audio and good motion matter but flagship pricing does not.
Product and marketing teams can iterate quickly on vertical video from existing key art (image-to-video) while keeping spend under control. Start/end frame workflows help bridge consecutive scenes when you plan transitions ahead of time.
Agencies balancing quality and margin can standardize on Lite for volume tiers and reserve full Veo 3.1 for hero assets or shots that need reference-image consistency or extension.
Why this model
Choose Veo 3.1 Lite when you want Google's audio-visual quality at a lower credit rate than full Veo 3.1, and when you do not need reference-image stacks or segment extension.
If your project already uses image models for start frames and narrator or captions elsewhere, Lite integrates cleanly: you pay per second of generated video at VidMachine's listed rate for this model.
How VidMachine uses it
Add Veo 3.1 Lite to your project's video model priority (alone or with fallbacks). We call it through our video pipeline with your scene prompts and start frames, using the same duration heuristics as other Veo-class models where applicable.
Credits are charged per second of output according to the model's rate on our pricing and billing docs. Combine with other video models in priority order to balance cost, speed, and quality.
What you should know
How does Lite differ from full Veo 3.1 on VidMachine?
Lite is priced lower per second and omits features such as multi-reference guidance and video extension. Both support strong image-to-video and native audio; full Veo 3.1 is the better fit when you need those extra controls.
Why might my clip be 720p instead of 1080p?
The provider requires 8-second duration for 1080p. Shorter scene targets map to 4s or 6s clips, which we send at 720p so the request stays valid.
How are credits calculated for Veo 3.1 Lite?
Video generation uses credits per second of output for this model. See the Pricing page and credits documentation for the current rate.
