Short answer: For AI text to video with Seedance 2.5, write duration and aspect ratio first, then the subject and action, then camera movement, then light and sound, and preview at 480p before the final render. A clear timeline in the prompt keeps the clip coherent from the opening beat to the ending frame.
How do I start an AI text to video generation?
Begin with one scene you can judge in a single pass: a product turn, a person walking into frame, or a short building fly-through. State the length and framing before decorative style words so the model knows the shape of the clip.
The Seedance 2.5 AI video generator supports text-to-video with continuous output from 4–30 seconds and resolutions of 480p, 720p, or 1080p. Aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9. Choose the ratio for the platform you will publish to before you refine camera language.
Keep the first draft focused. One subject, one primary action, and one ending pose are easier to evaluate than a multi-location montage. Free credits on sign-up let you run that first preview without committing to a paid plan.
What should a Seedance 2.5 text-to-video prompt include?
Write the prompt in a fixed order so each generation stays comparable when you change one variable.
- Duration and aspect ratio (for example, 12 seconds, 9:16).
- Subject and concrete action (who or what moves, and how).
- Camera movement (push-in, orbit, locked tripod, handheld follow).
- Light, materials, and optional sound (soft window light, polished metal, quiet room tone).
- Ending frame (what the viewer should still see at the last second).
Seedance 2.5 accepts second-by-second story instructions, so split the action into timed beats inside the 30-second limit. Preview at 480p to check pacing and framing, then raise resolution once the timeline works. For reusable prompt structure, use the Seedance 2.5 prompt formula.
When should I use text-to-video vs image-to-video vs first and last frames?
Pick the input mode that matches the control you need. Text alone is fastest for mood and motion tests; a reference image locks appearance; first and last frames pin the opening and closing composition.
| Mode | Best when | What you control most |
|---|---|---|
| Text-to-video | You are exploring motion, camera, and pacing without a locked look | Action, camera path, lighting language, timeline |
| Image-to-video | You already have a character, product, or key art to preserve | Appearance consistency while the prompt drives motion |
| First and last frames | The opening and closing compositions must match a board | Start and end framing, with motion filling the middle |
When a still must stay recognizable, follow the image-to-video workflow guide. When beats need exact second ranges, use the timestamp prompt guide.

Product turntable
Create a 10-second video in 1:1. A matte black wireless earbud case sits on a clean light-gray seamless background. Soft studio softboxes from the left. 0-3s: locked wide shot of the closed case. 3-7s: the case rotates slowly clockwise on a turntable while the camera holds steady. 7-10s: stop on a three-quarter view with the logo facing the lens. No hands, no text overlays, quiet room tone.Person walking into frame
Create a 12-second video in 9:16. A young adult in a navy jacket walks toward the camera along a quiet city sidewalk at blue hour. 0-4s: start on empty pavement and storefront lights. 4-9s: the person enters from the right and walks forward with a calm pace as the camera tracks backward smoothly. 9-12s: hold a medium shot as they stop and look slightly off-camera. Natural street reflections, no dialogue.Building lobby fly-through
Create an 18-second video in 16:9. A modern glass lobby with warm pendant lights and a stone reception desk. 0-5s: begin at the entrance looking inward. 5-12s: move the camera forward at walking speed through the lobby, keeping vertical lines stable. 12-18s: settle on a centered view of the desk with soft bokeh lights behind. Photoreal materials, quiet ambient hum, no people.Ad voiceover-ready product close-up
Create a 15-second video in 4:5. A glass bottle of citrus sparkling water with condensation beads on a sunlit kitchen counter. 0-4s: extreme close-up of condensation. 4-10s: slowly pull back to reveal the full bottle label while a soft breeze moves a linen curtain in the background. 10-15s: hold a clean hero angle with space on the right third for later text. Bright natural light, no on-screen captions, room tone only.Macro gear detail
Create an 8-second video in 16:9. Macro view of interlocking brass gears under a focused warm key light. 0-3s: static extreme close-up of two gear teeth. 3-6s: the gears begin a slow, even rotation. 6-8s: hold as a shallow depth-of-field highlight slides across polished metal. No text, soft mechanical whir optional.Vertical social hook
Create a 9-second video in 9:16. A ceramic coffee cup on a wooden desk beside an open notebook. 0-3s: overhead locked shot. 3-6s: a hand enters frame and lifts the cup slightly as steam rises. 6-9s: return the cup and hold. Soft morning window light, shallow depth of field, no logos other than the blank notebook page.Architectural dusk exterior
Create a 20-second video in 21:9. A low-rise concrete gallery with floor-to-ceiling windows at dusk. 0-6s: wide establishing shot from across the plaza. 6-14s: slow lateral move left to right as interior warm lights become visible. 14-20s: end on a balanced wide frame with the entrance doors centered. Photoreal, calm pacing, distant city hush.Character reaction beat
Create a 12-second video in 16:9. A barista behind a cafe counter notices a customer's order on the screen. 0-4s: medium shot, calm expression. 4-8s: eyes glance to the screen, then a small nod. 8-12s: they reach for a paper cup. Soft overhead practicals, shallow depth of field, no dialogue, gentle cafe ambience.For more scene templates after your first preview, browse the Seedance 2.5 prompt examples.
How do I refine a text-to-video clip after the 480p preview?
Judge the preview against the timeline you wrote. If a beat feels rushed, lengthen that second range and shorten a less important beat. If the subject drifts, simplify the camera instruction and keep the action line unchanged for the next try.
Seedance 2.5 supports up to 50 multimodal references when you later need a locked look, plus local edit and extend modes for finished clips. Stay on text-to-video until motion and pacing are right, then add references only for the details the text cannot hold. Open the Seedance 2.5 generator to run the next 480p preview with one changed variable.
Frequently asked questions
What is the best way to write AI text to video prompts?
Lead with duration and aspect ratio, then subject action, camera, light, and the ending frame. Keep each revision to one changed line so you can tell what improved.
How long can Seedance 2.5 text-to-video clips be?
Seedance 2.5 generates a continuous clip from 4–30 seconds in one pass. Stay inside that range rather than planning a single prompt that needs stitching.
Should I preview AI text to video at 480p?
Yes. A 480p preview uses fewer credits while you fix pacing and framing. Move to 720p or 1080p after the timeline reads clearly.
When should I switch from text-to-video to image-to-video?
Switch when a specific face, product, or key art must stay recognizable. Lock that look with a reference image, then keep using timed action lines for motion.
Can I try Seedance 2.5 text-to-video for free?
Yes. You get free credits on sign-up. Start with a short 480p scene and check the estimated credits before each generation.
