Veo 3.1 First & Last Frames Guide

Frames guide the opening and ending; they do not guarantee a pixel-for-pixel match. Review both endpoints and the movement between them before using the result.

First & Last Frames mode is for shots where the opening composition or the transition between two specific images matters. It accepts one or two images.

• One image: use the image as the starting point and describe how it should move.
• Two images: use the first and second images as the shot endpoints and describe a plausible path between them.

Use Reference Images instead when the main goal is to preserve a character or product identity without locking the first and last compositions.

Prepare the images

For one-image animation, choose a sharp source with a clear subject and enough visible space for the requested motion. A tightly cropped subject has less room to move.

For a two-image transition, make the frames compatible:

• keep the main subject recognizable;
• avoid unexplained wardrobe or product changes;
• use camera angles that can be connected naturally;
• keep lighting changes intentional;
• match the selected output aspect ratio.

The model can interpret a transition, but it cannot infer a coherent story from two unrelated frames without guidance.

Generate a one-image shot

1. Open the video generator.
2. Select First & Last Frames.
3. Upload the starting image.
4. Choose the model, duration, resolution, and aspect ratio.
5. Describe the subject motion and camera behavior.
6. Check the displayed credit cost and generate.

Example:

Begin from the uploaded frame. The leaves move in a gentle breeze while the
subject looks toward the window. Medium shot, slow camera push-in, stable face
and clothing, natural restrained motion.

Generate a two-image transition

Upload the starting frame first and the ending frame second. Write the prompt as a path:

Begin on the first frame. The camera moves slowly through the doorway as the
light changes from late afternoon to evening. End on the second frame with the
sign centered and the camera at rest.

Useful transition language includes:

• “begin on” and “end on”;
• “the camera moves toward”;
• “the subject turns gradually”;
• “the light changes from … to …”;
• “keep the same subject, clothing, and environment.”

Choose duration and aspect ratio

Veo3o1 exposes 4, 6, and 8 seconds where the selected combination supports them. Use a shorter duration for one clear action and a longer duration for a gradual transition. If the two frames need several unrelated events to connect, split the concept into separate shots.

Choose 16:9 for landscape delivery and 9:16 for mobile-first vertical delivery. Auto can be useful where supported, but an explicit ratio gives you a clearer target when both source images share the same composition.

Troubleshooting

The ending does not resemble the second frame

Reduce the visual gap between the two images and describe the transition more directly. Check subject, angle, lighting, and background continuity.

Motion feels unnatural

Remove competing actions. Ask for one subject movement and one camera movement at most.

The first image changes immediately

Start the prompt with “Begin from the uploaded frame” and repeat the details that must remain stable.

The transition is too abrupt

Use a longer supported duration and describe a gradual change. If the frames are unrelated, create an intermediate shot rather than forcing one generation to solve the entire sequence.

Before submitting

• Confirm image order.
• Confirm the destination aspect ratio.
• Check that the action fits the duration.
• Keep the prompt and frames visually compatible.
• Review the exact credit reservation.
