Wan 2.6 Image to Video Flash: the still is the contract (5s, 10s, 15s, 1080p, 8cr)

Wan 2.6 Image to Video Flash is image-to-video. If the label is wrong, every second is waste. The description is "Ultra-fast image-to-video conversion with Wan 2.6 Flash technology." Requires an image. audio is false. is_fast is true. Durations are only 5s, 10s, and 15s. Max output 1080p. Credits 8. Silent, fast, three lengths. The still is the contract. Speed is not a reason to animate a frame you have not approved.

This is not Wan 2.7. 2.7 starts at 2s, offers first-and-last-frame and continuation, and takes optional driving audio at 15 credits. Flash is the 8-credit mute shortcut. The Wan roster is where they sit next to each other. Do not mix the slugs.

Flash is silent on purpose

audio: false is the useful fact. There is no native dialogue, no multilingual mouth, no soundtrack you forgot to request. You will not get a talking presenter because the prompt mentioned a line. You will get motion on the still, quiet.

If the brief is a talking SKU, leave. Happy Horse 1.1 is the native-audio first-frame row. If the brief is a mute product push for a feed that will get VO later, Flash is correctly cheap: 8 credits, 1080p, 5 / 10 / 15.

Do not prompt "add voiceover" and expect the flag to flip. The flag is the row.

Three lengths, not a continuous slider

supports_durations is 5s, 10s, 15s. There is no 6s, no 8s, no 2s test. A 5s generate is the draft. 10s is the default ship length. 15s is the hold. Cutting a 15s Flash take down to 6s in an editor is fine; paying for 15s because you wanted 6s and the slider felt adjacent is not.

Quality settings are 720p and 1080p. Max is 1080p. Aspects are inferred from the still you send — lock the crop on the image before you generate. The image-to-video tool is the launcher.

Requires an image. A text prompt with no file is a different category. Text-to-video vs image-to-video if you do not own a frame yet.

Eight credits is for a locked still

Ultra-fast is for iteration on a picture that already survived review. It is not for discovering whether the bottle is the right bottle. Do that at 1–3 credits on a stills row. Then spend 8.

A wrong 15s Flash clip is still a wrong clip, just a faster one. Speed hides waste until the bill. Approve the frame. Pick 5s. If the motion is the motion you wanted, then 10 or 15.

Best image-to-video is the category ranking. Best Wan model is the family. This page is only Flash: mute, 5 / 10 / 15, 1080p, 8 credits, image required.

FAQ

Will Wan 2.6 Flash generate speech?

No. audio is false. Score or VO the clip after, or pick a native-audio image-to-video row.

Can I run 8 seconds?

Not as a listed duration. Choose 5s, 10s, or 15s. Trim in an editor if you need a length between those three.

Is Flash the same as Wan 2.7 image-to-video?

No. 2.7 is 2s–15s in one-second steps, three modes, optional driving audio, 15 credits. Flash is ultra-fast, silent, 5 / 10 / 15 only, 8 credits.

Do I need to upload a still?

Yes. requires_image is true. This row will not invent the product from text.
