Seedance 1.5 Pro: animate a still, then edit it properly

You already have the frame - a product shot, a still from a shoot, an image you generated a moment ago - and want up to 12s of movement out of it, at 720p, 480p or 1080p.

The clip you need fits inside 4s to 12s, and you can wait about 60s for it.

You need 16:9, 9:16 or 1:1 - no other image-to-video model here accepts as many natively.

You want sound generated with the picture instead of added on the timeline.

Cost is what decides it: nothing else here generates from a still for less than 5 credits.

Where it runs out: ByteDance built this endpoint to animate a still rather than to generate one, so there is no prompt-only path into it. Clips stop at 12s; Kling v3 Pro goes to 15s if you need one shot to run longer. Resolutions are limited to 720p, 480p or 1080p, and the higher ones cost more credits. Nor the quickest: PixVerse V6 answers in about 45s against this one's 60s.

Most generators hand you a clip and stop, which leaves you downloading files and re-uploading them somewhere else to make anything of them.

In REQO the Seedance 1.5 Pro result lands next to your screen recordings and uploads, about 60 seconds after you attach the still. Pick the aspect ratio before you generate (16:9, 9:16, 1:1); afterwards it is a crop.

The AI Studio (talking avatars, text-to-video and AI images) and the AI clip tools (background removal, chroma key, face touch-up, noise cancellation, auto cleanup, auto b-roll, auto-zoom) are Pro features. Generation includes 100 credits a month plus top-ups.
