Made with this app
How it works
Seedance 1.5 Pro is a text-to-video and image-to-video app built on ByteDance's Seedance 1.5 Pro model, producing clips from 4 to 12 seconds at resolutions up to 1080p. It is designed for creators who need production-ready video with native synchronized audio baked in, precise control over the final frame, and the flexibility of seven aspect ratios. Whether you are animating a still image or generating video from a written prompt, this app delivers cohesive motion and sound in a single generation pass.

What you can make
Social content with built-in audio
Seedance 1.5 Pro generates native synchronized audio alongside the video, eliminating the need for a separate sound design step. Create short social clips where ambient sound, music-like texture, or on-screen action audio matches the visuals from the first frame to the last.
Seamless scene transitions
The end-frame control feature lets you define exactly where a clip lands visually, making it straightforward to stitch multiple generations into a longer sequence. Useful for brand videos, narrative shorts, or any project where visual continuity between shots matters.
Vertical and widescreen format testing
With seven aspect ratios available, you can generate the same concept in portrait for Reels, square for feeds, and landscape for YouTube previews without re-prompting from scratch. Compare how motion and composition read across formats before committing to a final cut.
Animating product or concept imagery
Feed a static product photo or illustrated concept into the image-to-video mode and receive a polished 1080p clip with synchronized audio. Ideal for e-commerce demos, pitch deck animations, or turning client mood-board images into moving references.
High-resolution archival quality clips
At 1080p, the output is suitable for use in broadcast-adjacent contexts, print-to-screen transitions, or anywhere a 480p proxy would look soft. Generate up to 12 seconds of footage in a single run to reduce the number of generations needed for longer deliverables.
Prompt ideas to try
- A slow aerial drift over a foggy Japanese cedar forest at dawn, soft ambient wind sound, golden light breaking through the canopy, 12 seconds, cinematic wide format.
- A ceramic coffee mug on a marble countertop, steam rising in soft curves, warm kitchen background slightly out of focus, subtle morning ambience audio, 6 seconds.
- An architect's hand sketching a floor plan, the lines gradually transforming into a 3D rendered building exterior, pencil-on-paper sound, 8 seconds, vertical format.
- A vintage neon sign flickering to life in a rain-soaked alley at night, reflections rippling in puddles, low urban hum audio, 10 seconds, 1080p.
- A field of tall grass bending in synchronized waves under a dramatic overcast sky, low rumbling wind audio, wide aspect ratio, 12 seconds.
- Close-up of a vinyl record spinning, needle dropping into the groove, warm crackle audio synced to the moment of contact, 5 seconds, square format.

Tips for better results
Describe audio cues explicitly
Because Seedance 1.5 Pro generates native synchronized audio, including sound descriptors in your prompt, such as rain on glass, crowd murmur, or mechanical hum, gives the model context to align audio with the visual action rather than producing generic ambience.
Use end-frame control for sequences
When building a multi-clip sequence, define your end frame carefully so each clip hands off cleanly to the next. A consistent subject position, lighting angle, or color palette in the end frame reduces jarring cuts when you assemble the final edit.
Match aspect ratio to platform early
Choose your aspect ratio before finalizing your prompt. Motion that reads well in widescreen can feel cramped in portrait, and vice versa. Picking the right ratio upfront saves credits by avoiding re-generations solely to reframe the composition.
Extend duration for complex motion
The 4 to 12 second range gives you meaningful control over pacing. For slow reveals, gradual lighting changes, or multi-step actions, push toward 10 to 12 seconds. For snappy product cuts or loopable social content, shorter durations around 4 to 6 seconds tend to feel tighter.
When to choose this app
Choose Seedance 1.5 Pro over Seedance 2.0 Mini or LTX-2 Pro when your project requires native synchronized audio without a post-production audio pass and when 1080p output is a hard requirement. Compared to Seedance 2.0 Fast, this model prioritizes visual and audio fidelity over turnaround speed, making it the better fit for client-facing deliverables, polished social campaigns, or any clip where audio-visual sync is part of the creative concept.
Frequently asked questions
Can I use both text and an image as input at the same time?
Seedance 1.5 Pro supports text-to-video and image-to-video modes. In image-to-video mode your uploaded image anchors the visual starting point, and your text prompt guides the motion, style, and audio. You use one mode per generation rather than combining both inputs simultaneously.
How does end-frame control work in practice?
You supply an image that represents where you want the clip to conclude visually. The model uses that target to guide motion across the clip's duration, helping ensure the final frame matches your supplied image closely. This is especially useful for creating bridging shots between two pre-defined scenes.
Is the synchronized audio always present, or can I turn it off?
Native audio is optional. If your workflow requires a silent video, for instance when you plan to add a custom voiceover or licensed music in post, you can disable audio generation and receive a clean video-only file.
What happens if I request a duration longer than 12 seconds?
The maximum single-generation duration is 12 seconds. For longer sequences, the recommended approach is to use end-frame control to chain multiple generations together, maintaining visual continuity across clips in your editing timeline.
Which aspect ratios are available and how do I choose?
Seven aspect ratios are supported, covering common formats from vertical mobile to ultrawide cinematic. The right choice depends on your delivery platform. Vertical ratios suit Reels and Shorts, standard widescreen fits YouTube and presentations, and square works well for feed posts and thumbnails.
Does resolution affect how motion is rendered, or only the output file size?
Resolution affects perceptual detail in fine elements like hair, fabric texture, and background depth, not just file dimensions. At 1080p, motion in these fine areas reads more clearly than at 480p, which can make a difference in close-up product shots or detailed environmental scenes.
Which AI model powers this app?
This app runs on Seedance 1.5 Pro, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
