Seedance 2.5 AI Video Generator

15–30s one-take AI video with multi-reference prompts, image-to-video, and @video1 motion transfer. Try 480p at 5s first — credits show on the button before you run.

  • 15–30s one take

    Timed beats inside one export — not a multi-cut timeline

  • @video1 motion, your face

    Reference video supplies pacing — pixels rebuild from @image1

  • 30 / 10 / 10 refs

Job 01 / 02

Recorded run — inputs and prompt match this output.

Packshot used as the Seedance 2.5 start frame for a timed UGC ad

Product still

Output

Timed product UGC (10–15s)

Scenario
Hook, demo, and product hold must live in one vertical take.
Result
Same tumbler stays recognizable across second-level beats.
Settings

Prompt template

Use the tumbler photo as the start frame. Keep the sage ceramic body and wood lid unchanged. 0–3s: hand enters and sets the tumbler on a bright kitchen counter. 3–10s: slow push-in, faint steam, soft morning light. 10–15s: hold on the product, subtle orbit, no on-screen text. One continuous take, no hard cuts. For a 10s export, compress to 0–2s / 2–7s / 7–10s with the same actions.

Job 02 / 02

Recorded run — inputs and prompt match this output.

Lead photo used in the Seedance 2.5 reference run

@image1 identity

Trimmed clip used only as motion reference

@video1 motion

Output

TikTok-style motion on your photo

Scenario
You want the party pacing from a reference clip — not the stranger in it.
Result
@image1 locks who appears; @video1 is motion and camera only.
Settings

Prompt template

@image1 is the only person who should appear — same face, hair, and outfit as the photo. @video1 supplies party pacing and camera path only. Do not copy strangers, rooms, or text from @video1. One continuous take. No text.

Which mode matches your files?

Pick from what you upload — reference video rebuilds motion; it does not keep source pixels.

Photo must be frame one

Packshot or portrait is approved — you need motion and timed beats.

Image to video · Example 1

Photo + TikTok/Reels clip

You want their pacing, your character.

Multi-reference · Example 2

Script or beat list only

Nothing must survive as pixel-perfect frame one.

Text to video · or ref + @audio1

Rendered MP4 already

Fix a stretch or continue the story.

Extend · Video to Video ↓

Do not confuse @video1 with editing an MP4

@video1 reference

Motion, camera, or rhythm only. Output pixels are rebuilt — lock identity with @image1 (see Example 2).

Video to Video / Extend

You already have an MP4. Extend continues from the last frame; V2V patches a time range inside the same file.

What you pay (credits and ~USD) — start with 5s

A No @video1 → output seconds × rate (480p = 10 cr/s · 720p = 22 cr/s).

B With @video1 → (reference + output seconds) × lower rate (480p = 6 cr/s · 720p = 13 cr/s).

Try 480p for cheap proofs; move to 720p/1080p for finals. Images and audio alone do not add reference-video seconds.

5s proof (no ref video)

480p draft · from $1.19

50 credits · 480p

720p · from $2.62

110 credits · 720p

480p is the cheapest identity check — rerun at 720p when it holds.

10s, no ref video

480p draft · from $2.38

100 credits · 480p

720p · from $5.23

220 credits · 720p

10s ref + 15s output

480p draft · from $3.57

150 credits · 480p

720p + @video1 · from $7.73

325 credits · 720p

Typical @image1 + @video1 job.

30s, no ref video

480p draft · from $7.13

300 credits · 480p

720p · from $15.69

660 credits · 720p

Only after 5s proof looks right.

Yearly plans lower your cost per clip on Reeldo

Yearly billing grants 12× monthly credits at about 10× the monthly price (~2 months free). On Max, yearly is about $0.024/credit vs $0.029 on monthly (~17% lower per credit). One-time packs (Popular) run about $0.045/credit — ~48% higher than Max yearly. ~USD below uses Max yearly; monthly subs or packs increase the dollar amount.

Clip wrong? Change one line — not more refs

Seedance 2.5 drifts when @ jobs overlap. Fix the symptom, rerun 5s at 720p.

Face or product morphed

Extra refs or @video1 copied identity pixels.

@image1 (or product) only — say do not copy people, rooms, or text from @video1. Drop unused @images.

Looks like the reference performer

Motion ref not isolated.

@video1 = pacing and camera path only. Match body scale; forbid copying clothes and background from @video1.

Story beats land at wrong times

Vague prompt or fighting refs.

Rewrite contiguous seconds (0–5s / 5–15s / 15–30s). One change per retry.

Burned credits on a bad 30s

Skipped proof pass.

5s @720p first — see cost cards above — then scale length.

Pattern A — timed product (Example 1)

Start frame = product photo.
0–3s hook · 3–10s demo · 10–15s hold.
One continuous take, no on-screen text.

Pattern B — motion on your photo (Example 2)

@image1 = who appears.
@video1 = motion + camera only.
Do not copy strangers or rooms from @video1.
Advanced: five habits that reduce drift
  1. 1. Contiguous second ranges

    Steer phases with 0–5s / 5–15s — not frame numbers or an edit timeline.

  2. 2. One job per file

    @image1 identity/product · @video1 motion · @audio1 rhythm.

  3. 3. Resolve ref fights

    If two images disagree, remove one or name the winner in text.

  4. 4. Lock non-negotiables

    Face, product shape, duration, no on-screen text — spell them out.

  5. 5. One variable per retry

    More refs ≠ more stable. Change one line, rerun 5s.

Already have an MP4 — extend, edit, or regenerate?

Branch 1

Last frame pose is stable; story should continue

Extend — match last frame to the next pass

Chain for >30s total; watch motion continuity.

Branch 2

One stretch fails; rest of the file is usable

Video to Video with seconds + protect list

If output barely changes, rebuild with reference mode instead of repeating the same edit prompt.

Branch 3

Wrong person or product from frame one

New Seedance 2.5 run with tighter @ tags

Editing rarely fixes a bad first frame.

After export

  1. Download & check last second

    Face, product, and motion at the end frame — before upscale.

  2. Upscale when motion is approved

    Do not upscale a draft you will regenerate.

  3. Need 20/25s or another pass

    Open Video Studio — same credit balance.

Use something else when…

When

Cheap 15s motion tests

Seedance 2 Fast → /seedance-2

9 cr/s @720p. Seedance 2.5 is for longer single takes and heavy refs.

When

Several planned cuts in one export

Kling 3.0 → /kling

Multi-shot planning — not one continuous beat prompt.

When

4–8s spoken close-up

Veo 3.1 → /veo

Short native dialogue — not 30s reference-heavy takes.

When

Readable on-screen type or logo

Post-production or MiniMax H3

Seedance will not hold small text reliably.
