Veo 3.1 Fast - Image to Video

Veo 3.1 Fast is Google's advanced AI model offering higher quality and more control. Key differences: manual aspect ratio selection (vs auto-detect), optional audio generation (vs always included), longer prompt support (1000 vs 800 chars), and different duration options (4s/6s/8s vs 5s/10s).

Use Veo 3.1 Fast when you need high-quality output, specific aspect ratio control, or want flexibility with audio. Use Wan 2.5 for budget-friendly generation with automatic audio included and when you want the aspect ratio to match your source image automatically.

Veo 3.1 Fast supports common image formats including JPG, JPEG, PNG, and WEBP. For best results, use high-quality images with clear subjects and good lighting.

Unlike some models that auto-detect aspect ratios, Veo 3.1 Fast lets you manually choose: 16:9 for landscape (YouTube, web), 9:16 for portrait (TikTok, Instagram Stories), or 1:1 for square (Instagram posts). This gives you full control over output dimensions.

No! Audio generation is optional in Veo 3.1 Fast. You can toggle it on or off based on your needs. With audio enabled, you'll get synchronized sound effects and ambiance, but it costs extra credits. Without audio, you get a silent video at lower cost.

Describe the type of motion you want to see. Include details about camera movement (zoom, pan, tilt), object movement, lighting changes, atmospheric effects, and animation style. For example: 'slow camera zoom in, gentle breeze moving the leaves, golden hour lighting with soft shadows.'

Veo 3.1 Fast supports three duration options: 4 seconds, 6 seconds, and 8 seconds. Choose based on your content needs and budget, as longer durations cost more credits.

Veo 3.1 Fast offers two resolution options: 720p for faster generation at lower cost, and 1080p for high-quality, professional-grade output. Both resolutions support all aspect ratios.

Pricing is based on resolution, duration, and audio: 720p with audio (30 credits/second), 720p without audio (20 credits/second), 1080p with audio (40 credits/second), 1080p without audio (30 credits/second). For example, a 4-second 720p video with audio costs 120 credits.

Veo 3.1 Fast typically generates videos in 20-60 seconds, depending on the selected duration and resolution. The model is optimized for speed while maintaining high quality.

Yes! You can upload the same image and generate multiple videos with different animation prompts, aspect ratios, or durations to explore various creative directions.

Use high-quality images with clear subjects, good lighting, and interesting composition. Images with depth, foreground and background elements, and distinct subjects tend to produce more dynamic animations.
