VEO 3.1 AI 영상 생성

VEO 3.1 is Google DeepMind's third-generation text-to-video model and the production successor to VEO 2. Unlike Sora's variable-length clips, every VEO 3.1 generation is a fixed 8 seconds — the model is optimized for that exact window, which makes it a strong fit for social formats and product loops.

All three variants — Lite, Fast and Quality — share the same core: 8-second 720p output, 16:9 or 9:16 aspect, native synchronized audio, and three input modes (text-to-video, image-to-video with a single first frame, and first/last frame control where you supply both endpoints and the model interpolates the motion between them).

The three tiers trade quality for cost. VEO 3.1 Lite is the gateway at 24 credits per clip — useful for storyboarding, mood-board iteration and animatic-style work. VEO 3.1 Fast at 45 credits is the everyday workhorse with materially better physics and lighting. VEO 3.1 Quality at 90 credits — exactly double Fast — is the flagship: best texture detail, most coherent character motion, and the right pick for hero shots and final deliverables.

VEO is particularly strong at outdoor scenes, natural light, water and wind, and on-camera dialogue with lip-sync that holds up. It is weaker than Sora 2 Pro for indoor cinematic lighting and weaker than Seedance for stylized animation. First/last frame mode is unique within the VEO family on FlyAIgh — it gives you a guaranteed start and end pose, which is invaluable for tight editorial cuts.

On FlyAIgh, all three VEO 3.1 variants are available on every plan without a separate Google Cloud account, API project or quota request. The credit cost is the only difference between Free and Pro tiers.
