Wan 2.7 Image to Video: the still is the contract (2s, 3s, 4s, 1080p, 15cr)

Wan 2.7 Image to Video is image-to-video. If the label is wrong, every second is waste. Wan animates images with three modes: first-frame to video, first-and-last-frame interpolation, or video continuation, with optional driving audio. Requires an image. Max output 1080p. Durations from 2s to 15s. Credits 15. The still is the contract. The mode is how you spend it.

This is not the Wan 2.7 text-to-video row and not the reference-to-video row. Same generation number, different slugs. The Wan roster lists them separately. Best Wan model is the family ranking. This page is only image-to-video.

Three modes, one still you already approved

First-frame. Your upload is 0:00. The model invents motion forward. Prompt camera and action, not a new background.

First-and-last-frame. You pin both ends. Use this when the product must land in a known composition — cap on, label readable, end card already designed. Interpolation is not a new scene; it is a path between two locked stills.

Video continuation. You extend footage you already have. That is not how you invent the product. That is how you hold a take that is already on-model.

All three assume the picture is right. If the label is misspelled in the still, every mode will spend 15 credits animating the typo. Fix the frame on text to image or an edit model, then come back. The image-to-video tool is the launcher.

Driving audio is optional, not native

audio on this snapshot is empty. The description says optional driving audio — a track you supply, not a soundtrack the model always invents. That is the opposite of a native-audio row. If you needed baked-in dialogue from a silent prompt, this is the wrong Wan. If you have a VO you want the motion to follow, driving audio is the knob.

Do not confuse this with Wan 2.6 Image to Video Flash, which lists audio: false and only 5s / 10s / 15s. 2.7 is the three-mode row at 15 credits, starting at 2s.

2s is the floor; 15s is the ceiling

Durations: 2s, 3s, 4s, then every second through 15s. Happy Horse's floor is 3s. This floor is 2s. Use 2s to see whether the still holds. Use 15s only after the 2s take already has the right motion. Quality settings are 720p and 1080p. Max is 1080p.

15 credits is the catalog price. It is not a reason to skip the 2s test. A wrong 15s clip is a longer wrong clip.

Prompting notes for the family live in the Wan 2.7 prompting guide. Category context: best image-to-video. If you needed the subject restaged in a new world, that is Wan 2.7 reference-to-video, a different slug.

FAQ

Do I have to upload an image?

Yes. requires_image is true. Text-only belongs on Wan's text-to-video slug, not this one.

What is driving audio on Wan 2.7?

An optional track you attach so motion can follow it. It is not automatic native sound. The audio field on the row is unset.

Can I interpolate two stills?

Yes. First-and-last-frame is one of the three listed modes. Both stills should already be approved. The model fills the path; it does not redesign the product.

Why 15 credits instead of the Flash row's 8?

Different spec. This row starts at 2s, runs to 15s in one-second steps, offers three modes, and takes optional driving audio, at 1080p and 15 credits. Flash is the silent 5 / 10 / 15 shortcut. Pick the row that matches the job.
