Image to Video — First & Last Frame

Upload a first frame (required) and optional last frame—two still images, not a multi-image board. Describe motion between them and generate video with Seedance 2.0 or VEO 3.1.

  • First frame required · last frame optional (two slots only)
  • Seedance 2.0 & VEO 3.1 — not the same as Multi-images to Video
  • Motion prompts up to 4,000 characters; ~500 enough for most shots
Two frame slots: start (required) + end (optional)
JPEG, PNG, or WebP frame uploads
Seedance: adaptive ratio + optional last-frame mode
VEO 3.1: 16:9 or 9:16 · 4 / 6 / 8 seconds

Models

Which models support Image to Video?

Dashboard → Image to Video. Both models animate from your uploaded first frame (and optional last frame)—they do not accept arbitrary multi-image reference boards here.

Inputs

What do you submit?

You provide up to two still images with defined roles—not a gallery of multiple reference images.

Frame uploads

What makes good first and last frames?

Because the model interpolates between defined start/end stills, frame quality and alignment matter more than prompt length.

Frame tip — first frame example

Strong first frame

Use a sharp, well-lit still with clear subject separation. The first frame is always sent as first frame (start)—it anchors identity, pose, and composition.

Frame tip — last frame example

Optional last frame for known endings

Upload a last frame (last frame) when you know the exact end composition—product fully revealed, door open, logo centered. Skip it when you only need motion from a single still.

Frame tip — aligned frame pair

Align perspective and lighting

Match scale, camera angle, and color temperature between frames to reduce morph artifacts. Keep the subject in similar positions when using both frames.

Prompting

Motion prompts for frame-based video

First frame only (no last frame)

Describe camera and subject motion explicitly: “Static product on table; slow orbit clockwise; soft studio light; shallow depth of field.” One clear camera verb works best.

First + last frame pair

Keep the prompt about transition: “Smooth morph from closed box to open box with product visible; maintain label readability; gentle ease-in-out.” Let the frames define start/end.

Camera path language

Use plain verbs: dolly in/out, pan left/right, orbit, crane up, handheld drift. Example: “Slow dolly-in on portrait; background bokeh; golden hour rim light.”

When to use this tool

Image to Video vs other tools

Image to Video is “defined start/end stills → motion clip.” It is not Text to Video (words only) and not Multi-images to Video (many references without frame roles).

Examples

Replace with your best first/last frame workflows to build trust from search.

Single-frame dolly

Only first frame uploaded; motion from prompt.

Box open reveal

First and last frame define closed → open states.

Portrait subtle move

Anchored face with gentle camera drift.

Product orbit

Studio product still with orbital motion.

FAQ

Is Image to Video the same as Multi-images to Video?

No. Image to Video uses exactly two frame roles—a required first frame and optional last frame. Multi-images to Video accepts 1–9 reference images without first/last roles and only supports Seedance 2.0.

Do I have to upload a last frame?

No. Only the first frame is required. Without a last frame, describe motion in your prompt (camera move, subject action).

What file types can I upload?

JPEG, PNG, or WebP still images in the frame upload slots.

Which models are available?

Seedance 2.0 and VEO 3.1 from the model picker. Settings differ: Seedance uses adaptive aspect ratio; VEO requires 16:9 or 9:16 and fixed 4/6/8s durations.

What happens if I forget the first frame?

The dashboard shows “First frame image is required” and blocks Generate.

When should I use Text to Video instead?

When you have no still frames yet and can describe the full shot in text only.

How long can my prompt be?

Up to 4,000 characters; the UI recommends around 500 for most shots.

Can I use outputs commercially?

Commercial usage depends on your plan and terms. Review pricing and policies before shipping at scale.

Animate from first & last frames

Upload your start still, optionally your end still, describe motion, and generate.
