Veo 3.1 Fast generates videos in 30-45 seconds and costs 100 credits (~$0.92). It's perfect for quick content, social media posts, and testing ideas. Veo 3.1 Quality takes 45-60 seconds, costs 250 credits (~$2.31), and produces higher quality videos with better detail, consistency, and realism. Use Quality mode for professional content, ads, and when you need the absolute best results.

Frame control lets you upload 1 or 2 images to guide your video generation. Upload 1 image and the video will center around that image, animating it with your prompt. Upload 2 images and Veo 3.1 creates a smooth transition from the first frame to the last frame. This is perfect for consistent character videos, product animations, or creating videos with specific start and end points. Images must be JPG/PNG format, max 10MB each.

Fallback mode (+200 credits) automatically switches to a backup model if your prompt is rejected due to content policies or if generation fails. This increases your success rate from ~85% to 99%. If you're creating important content and can't afford failed generations, fallback mode is worth it. Credits are automatically refunded if both models fail.

The seed (10000-99999) is used for reproducible results. If you generate a video with seed 42069 and like the result, you can use the same seed again with a similar prompt to get consistent style and composition.
