AI First & Last Frame Video Generator

First and last frame video generation is an AI technique that creates a video by interpolating between two keyframes — the starting image (first frame) and the ending image (last frame). The AI analyzes both frames and generates all intermediate frames to produce smooth, natural motion from one state to another.

Several models on our platform support this feature. Wan2.1 First+Last Frame requires both frames. Seedance 1.5 Pro, Seedance Lite, Veo 3.1, and Veo 3.1 Fast all support an optional last frame — you can provide just the first frame or both frames for more precise control.

No. Some models like Wan2.1 First+Last Frame require both frames, but most models including Seedance and Veo 3.1 variants treat the last frame as optional. When only the first frame is provided, the AI generates the motion based on your text prompt alone. Adding a last frame gives you precise control over where the video ends.

Most models accept JPG, PNG, and WEBP formats. For best results, use high-quality images with at least 512x512 pixel resolution. Both the first and last frames should ideally have the same aspect ratio and resolution to ensure smooth interpolation.

Generation time varies by model and settings, typically ranging from 1 to 5 minutes. Standard models process in about 2-3 minutes, while fast variants like Veo 3.1 Fast and Seedance 1.5 Pro (Fast) can complete in under 2 minutes. Higher resolutions and longer durations may require additional processing time.

Credit costs vary by model and parameters selected. Each model has its own pricing based on resolution, duration, and quality settings. You can see the exact credit cost before generating. Premium models like Veo 3.1 Pro typically cost more credits than standard versions.

Yes, videos generated on our platform can be used for commercial purposes. This includes marketing materials, social media content, presentations, advertisements, and other professional projects.

For best results: 1) Use high-quality, clear images for both frames. 2) Keep the visual difference between first and last frames reasonable — extreme changes may produce unrealistic results. 3) Write detailed prompts describing the desired motion and transition. 4) Ensure both frames have the same aspect ratio. 5) Start with shorter durations and increase as needed. 6) Try different models to find which one best suits your specific use case.
