# Seedance 2.5 prompts: a guide for product and brand video Name every reference, time every beat, put the sound where it happens. Eight Seedance 2.5 prompts for product and brand video you can copy. 21 Oct 2026 · 10 min read · Models · By Sloosh Web page: https://sloosh.ai/blog/seedance-2-5-prompts A good Seedance 2.5 prompt does three things. It names every reference by number and job ("@Image 1 is the product"). It plots the clip as timed beats in whole seconds, like `0-3s:`. And it writes sound into each beat: dialogue in quotes, sound effects in ``. One camera move per beat. Lock the label. ## Key facts - **Clip length:** 4 to 30 seconds, in whole seconds, in one run. - **Output:** 480p, 720p or 1080p, in auto, 21:9, 16:9, 4:3, 1:1, 3:4 or 9:16. - **References:** ByteDance allows up to 30 images, 10 videos and 10 audio clips ([TechNode](https://technode.com/2026/07/31/bytedance-launches-seedance-2-5-video-generation-model/)). Sloosh Studio takes up to 30 images, 10 videos (each at least 2 seconds, 30 seconds in total) and 10 audio clips. - **Sound:** on by default. Turning it off can change the price. - **Frames:** start and end frames are optional, but can't be mixed with reference images. - **In Sloosh:** the default video model in Studio. Specs on the [Seedance 2.5 docs page](https://sloosh.ai/docs/seedance-2-5). ## Why does your first Seedance 2.5 clip fall apart? Your first clip looks great for four seconds. Then the bottle grows a second dropper. The label turns to soup. A cut you never asked for lands at second nine. The model didn't know which image was the product, so it improvised. You packed three actions into one beat, so it cut to fit them in. You asked for on-screen text in words alone, and it spelled the way models spell. Each one has a fix you can type. ## What's new in Seedance 2.5? ByteDance released Seedance 2.5 on July 31, 2026. It makes a 30-second clip in a single run and takes up to 30 images, 10 videos and 10 audio clips as input ([TechNode](https://technode.com/2026/07/31/bytedance-launches-seedance-2-5-video-generation-model/)). Thirty seconds is a full ad: hook, demo, payoff, end card. On 2.0 you stitched two 15-second clips and hoped the light matched. ## What does a good Seedance 2.5 prompt look like? Four blocks, in this order: **The structure** ```text [Roles] @Image 1 is ... @Image 2 is ... @Video 1 is ... [Premise] One sentence: subject, place, event, style, camera. [Beats] 0-3s: visual, camera, action, sound. 3-7s: ... [Locks] What must stay exact. What to leave out. ``` Only subject and event are essential, per [ClipDance's guide](https://clipdance.ai/blog/seedance-2-prompts-guide). The rest is steering. Timing works in ranges (`0-3s:`), exact moments ("at the 5-second mark") or relative cues ("after 3 seconds"), all in whole seconds ([BytePlus](https://docs.byteplus.com/en/docs/modelark/seedance-2-5-prompt-guide)). Leave no gaps between beats. ## How do reference images work in Seedance 2.5? References are numbered in the order you add them. Give each one a role line and say what must not change, like the first line of prompt 1 below. Seedance reads `@Image 1` as a pointer to that exact file. In Sloosh, tagging depends on where you write ([tagging docs](https://sloosh.ai/docs/tagging)): - **Seedance Spaces:** upload to the form, then type `@` to insert `@Image 1` or `@Video 1`. - **Studio:** `@` lists your Elements, so you write `@red-sneakers`. - **Editing a clip:** the clip you edit is `@Video 1`. Keep it to 1 to 8 subjects, with reference videos of 5 to 10 seconds. BytePlus says that range generally works better, and stability can drop past it. ## How do you add audio, dialogue and music? Sound is on by default. Write it into the beat where it happens. | Sound | How to write it | Where it comes from | | --- | --- | --- | | Dialogue | "I need to talk about this bottle." with the speaker named. The 2.0 guide and ClipDance use {braces} | BytePlus 2.5 examples, Sloosh docs | | Sound effects | | Sloosh docs, BytePlus 2.0 guide, ClipDance | | Music | (low warm synth pad) | BytePlus 2.0 guide (full-width （ ）), ClipDance | | Captions you want | 【SALE ENDS SUNDAY】 | BytePlus 2.0 guide, ClipDance | | Things you don't | No subtitles.

BytePlus warns the same prompt looks visibly different on 2.5, and its 2.0 guide says 2.0's support for precise timing is unstable, so re-test old 2.0 prompts and write them by shot number. Draft on 2.0 Fast, finish on 2.5 or 2.0. ## What do Seedance 2.5 Spaces show about structure? Two Sloosh Spaces run on Seedance 2.5, and both are built on timed beats. [Love Story Trailer](https://sloosh.ai/spaces/love-story-trailer) turns two photos into a 20-second film. Seconds 0 to 9 play your real moment, up to the "yes". Seconds 9 to 20 cut into a movie trailer in the genre you pick. [Birthday Blockbuster](https://sloosh.ai/spaces/birthday-blockbuster) opens on cake and candles (0 to 10s), then explodes into a blockbuster starring the birthday star (10 to 20s). Two acts and a hard turn at a fixed second. Steal it for an ad: the problem for 8 seconds, the product for the rest. ## When is Seedance 2.5 the wrong model? **You need 4K.** Seedance 2.5 tops out at 1080p in Sloosh. Use Seedance 2.0 or MiniMax H3. **You need exact words on screen.** Put the words in an image reference, like prompt 4, or add them in your editor. **You're testing ideas.** Run Seedance 2.0 Fast at 480p, then rerun the winner on 2.5. **You need one exact frame to move.** Use it as a start frame, and drop the reference images: the two can't share a run. ## Can you run Seedance 2.5 from Claude or ChatGPT? Yes, through the Sloosh MCP server on every plan, from Claude, Codex or Cursor, or from ChatGPT in a Business or Enterprise/Edu workspace. Your assistant quotes the clip, runs it and hands back the result. See the guide to [generating images and video in Claude, ChatGPT and Cursor](https://sloosh.ai/blog/generate-images-in-claude). ## Name it, time it, hear it Name every reference. Time every beat.
