Overview

About this model

SD 2 First & Last Frame VIP (Pro) generates video that transitions between two reference images with priority routing. Provide one image as the opening frame, or two images for a complete start-to-end transition. Output resolution is selectable directly on this endpoint — 720p, 1080p, or 4K — via the resolution parameter, and price scales with your choice. Uses the pro model for maximum output quality.

1Scene Transitions: Create smooth video transitions between two distinct visual states for film or social content.
2Before/After Videos: Generate compelling before-and-after transformation videos from two endpoint images.
3Narrative Sequences: Build visual story segments by defining where a scene starts and ends.

Common Questions

Frequently asked

What is the difference between First & Last Frame and Image-to-Video?

First & Last Frame accepts up to 2 images and generates a controlled transition between a start and end frame, while Image-to-Video animates from a single start frame with optional reference images.

What resolutions does SD 2 VIP First & Last Frame support?

Set `resolution` to `720p` (default), `1080p`, or `4k`. Price scales with resolution: $0.30/sec at 720p, $0.675/sec at 1080p, and $1.35/sec at 4K.

Can I use character references in First & Last Frame?

Yes, use @character:<request_id> from a completed SD 2 Character generation, or @omni-character:<char_id> for a trained character.

How does cost scale with duration?

At 720p, a 5-second video costs $1.50 and a 10-second video costs $3.00. Costs scale proportionally at 1080p and 4K.

Do the dedicated -1080p and -4k endpoints still work?

Yes, seedance-2-vip-first-last-frame-1080p and seedance-2-vip-first-last-frame-4k remain fully live, but the base endpoint now covers every resolution via the `resolution` parameter.
