Seedance V1.5 Pro Image to Video

Frequently Asked Questions

What is Seedance V1.5 Pro Image to Video?

Seedance V1.5 Pro I2V is Bytedance's advanced image-to-video model that transforms static images into high-quality cinematic videos. It features ultra-fast generation speed while maintaining excellent motion quality, coherent storytelling, and smooth camera movements.

How does the first and last frame control work?

You can upload a starting image (first frame) and optionally an ending image (last frame). The model will generate a smooth video transition between these two frames. If only the first frame is provided, the model generates motion based on your prompt. This feature is ideal for creating controlled animations with predictable start and end states.

What are the supported video durations and resolutions?

Duration: 4-12 seconds with flexible selection. Resolutions: 720p (balanced quality and speed) and 1080p (highest quality). Aspect ratios include 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16, or auto-detect from input image.

How should I write effective prompts?

Describe the motion and action you want to see, not just the scene. Include camera movement instructions like 'slow zoom in', 'pan left', or 'tracking shot'. Mention lighting, atmosphere, and emotional tone. Keep prompts specific but concise. Example: 'A woman smiles gently as wind blows through her hair, soft golden hour lighting, slow camera push in'.

What are common use cases for this model?

Perfect for product animations (bringing product photos to life), social media content (creating engaging video posts from images), storytelling (animating illustrations or concept art), marketing materials (converting static ads to video), and portrait animations (adding subtle motion to photos).
