Turning a still photo into a moving video clip takes about a minute with AI: upload the image, describe how it should move, and generate. The trick that separates a good result from a melting mess is what you write in the prompt. Here's the full process with Seedance 2, the prompt patterns that actually work, and what it costs.
TL;DR
- What you'll make: a 5–12 second video animated from a single photo (image-to-video).
- How: upload → describe the motion → set resolution/length → generate. ~150 credits for a 5-second 720p clip.
- Cost/time: about a minute; new accounts start with free credits, so your first clips are free.
- Key tip: describe motion and camera, not the contents of the image — the photo already sets the look.
Step 1 — Pick and upload a good photo
Image-to-video animates what you give it, so the input matters. A clear photo with one strong subject (a person, a product, a landscape) animates more cleanly than a busy, cluttered scene. High resolution helps. Open the generator, choose Seedance 2, and switch to image-to-video, then upload your photo.
Step 2 — Describe the motion, not the content
This is the part most people get wrong. The image already shows what is in the shot, so don't waste the prompt re-describing it. Spend it on how things move:
- Subject motion: "hair drifting in the wind," "steam rising from the cup," "she turns her head slightly and smiles."
- Camera motion: name the move — "slow push-in," "gentle dolly left," "subtle handheld sway," "orbit around the subject."
- Pace and mood: "slow and cinematic," "quick energetic zoom."
A prompt like "slow push-in, gentle wind moving the leaves, soft morning light" beats "a beautiful nature video." Specific motion = controlled motion.
Step 3 — Set resolution and duration, check the cost
Pick 480p / 720p / 1080p and the clip length. The generator previews the exact credit cost before you confirm — a 5-second 720p image-to-video clip is around 150 credits. Higher resolution and longer duration cost more; a short 480p draft costs less. Start small while you dial in the prompt.
Step 4 — Generate, then refine
Run it. If the motion isn't right, adjust the prompt and try again — and because failed generations aren't charged, experimenting is cheap. A reliable workflow: draft on the lower-cost Seedance 2 Fast / 2.0 Mini tier (~105 credits for image-to-video) until the motion looks right, then re-render the keeper on standard Seedance 2.
Common mistakes
- Over-describing the image. Trust the photo; prompt the motion.
- Asking for too much motion at once. One or two clear movements read better than a chaotic list.
- Ignoring the camera. "Static shot" vs "slow orbit" completely changes the feel — always specify.
- Starting at 1080p. Draft cheap, finalize once.
What it costs
One credit pool covers every model, and the cost shows before each run:
| Output (5s, 720p) | ~Credits |
|---|---|
| Image-to-video — Seedance 2 | ~150 |
| Image-to-video — Seedance 2 Fast / 2.0 Mini | ~105 |
| Text-to-video — Seedance 2 | ~300 |
New accounts get free credits to start. After that, the cheapest pack is $29.90 → 3,150 credits (~20 image-to-video clips). See pricing for the full breakdown.
FAQ
How do I turn a photo into a video with AI?
Upload the photo to an image-to-video generator, describe the motion you want, set resolution and length, and generate. On seedance-21.app a 5-second 720p clip costs about 150 credits.
Is it free?
New accounts start with free credits, enough to animate a few photos before paying. See Free Image to Video for the free routes and their limits.
Why does my animated photo look distorted?
Usually too much requested motion, a cluttered source image, or a vague prompt. Use a clean photo and describe one or two specific movements plus the camera.
How long can the clip be?
Length is selectable; longer clips cost more credits. Most people start with 5-second clips.
What's the difference from text-to-video?
Image-to-video animates a photo you upload (more control over the look, ~150 credits); text-to-video builds the whole clip from a prompt (~300 credits). See Text-to-Video AI: How It Works.
