Seedance Image to Video Workflow

Why start from an image

Seedance image to video works from a frame you already control. That is useful when the subject cannot be described reliably in words: a specific product, a real face, a brand-owned set. The model keeps the composition and animates it, so you spend the prompt on motion instead of describing what the picture should contain.

Seedance 2.0 accepts an image in the studio picker, and the 2.5 Pro variant also lists image input. The difference is what happens after the first pass: 2.0 adds Retake, Extend, HDR Upscale and Video Reframe, while 2.5 adds native multishot for connected scenes.

Step 1: prepare the frame

The still sets the ceiling for the clip. Before uploading:

• Match the delivery ratio. A 16:9 image for a 9:16 clip will be cropped or padded. Crop first.
• Use enough resolution. A soft source stays soft after upscaling.
• Keep one clear subject. Two competing focal points make motion ambiguous.
• Check the light direction. It is easier to extend existing light than to invent a new source.
• Avoid baked-in text. The model may warp lettering as it moves.

If the frame needs cleanup, do it before generation. Editing a still is faster than repairing a clip.

Step 2: describe only the motion

With an image uploaded, the prompt should answer four things:

1. What moves. Hair, fabric, steam, a hand, the camera.
2. How it moves. Direction, speed and rhythm.
3. What stays still. The product label, the subject's pose, the horizon.
4. How light changes. A shadow crossing the set, a slow shift in intensity.

A compact example: "Steam rises from the cup, the curtain drifts left to right, the camera pushes in slowly, the cup and saucer stay fixed, warm light stays constant."

Notice that the prompt never re-describes the cup. The image already did that.

Step 3: choose the model

Use this split:

• Seedance 2.5 when the clip needs more than one connected shot, or when native audio matters.
• Seedance 2.0 when the shot needs a retake, an extension, an HDR upscale, a different frame, or a square/wider delivery size.
• Seedance 2.0 Fast for cheap motion tests before committing to a final pass.

The comparison guide breaks this down shot by shot.

Step 4: generate a draft at 720p

Test the motion at the lowest useful tier. A 720p draft on Seedance 2.0 Fast is listed at $0.03 per second, which is 3 credits per second at the studio's $1 = 100 credits rate. A five-second test costs about 15 credits. Once the motion is right, move the selected take to a higher resolution or finish it with the edit tools.

Do not upscale a clip whose motion you have not approved. Resolution is the expensive part of the workflow.

Step 5: finish, don't reroll

When the motion is close but not correct:

• Retake fixes the section that moves wrong.
• Extend adds time when the action ends early.
• HDR Upscale lifts the selected clip to a 4K HDR delivery.
• Video Reframe adapts the same take to another aspect ratio.

This is where the image-to-video workflow saves the most credits. Regenerating changes everything; a targeted edit changes one thing.

Common problems and fixes

Problem	Likely cause	Fix
Subject morphs	Motion prompt is too broad	Name what stays still
Camera drifts	Several moves in one line	Keep one camera instruction
Colors shift	New light was invented	Say the light stays constant
Crop cuts the subject	Ratio mismatch	Crop the source before upload
Motion looks rushed	Pace not stated	Add "slow" or a beat reference

FAQ

Which models support image-to-video?

Seedance 2.0 supports image-to-video in the studio. Image input is also listed for the Seedance 2.5 Pro variant; confirm the option for your selected model before uploading.

Can I use a photo of a real person?

You need the rights to any reference image you upload, including a person's likeness. Credit packs include a commercial license for generated clips, but the upstream model license and your source-image rights still apply.

Should I prompt the subject again?

No. Describe the motion, the camera and what stays still. Re-describing the subject wastes prompt space and can push the model away from the source frame.

Can I change the aspect ratio after generating?

On Seedance 2.0 Pro, Video Reframe changes the frame. Otherwise, crop the source image to the target ratio before generation.

Conclusion

Prepare the frame, prompt only the motion, draft at 720p, then finish with the Seedance 2.0 tools or move to Seedance 2.5 for connected shots. Open the generator with your still and check credit pricing before a longer batch.
