Why creators use Seedance 2.5 Flash

Flash keeps what makes Seedance 2.5 useful for short-form, one coherent shot that holds motion, lighting and subject identity for up to 30 seconds with sound generated in the same pass, while turning a render around in about half the time.

That speed and the lower per-second price make it the Seedance to iterate with: try a few versions of a hook, a product shot or a scene, and keep the full Seedance 2.5 for the take where the last bit of detail matters.

What you can make with Seedance 2.5 Flash

•High-volume short-form clips for TikTok, YouTube Shorts and Instagram Reels, where speed and price matter more than 1080p.
•Drafting and testing prompts quickly before a final render on the full Seedance 2.5.
•Long single-shot product or demo clips up to 30 seconds, with sound in the same render.
•Reference-led clips that match a product, character or style, using up to 10 images and 5 videos.

Seedance 2.5 Flash FAQ

What is the difference between Seedance 2.5 Flash and Seedance 2.5?

Flash takes the same kinds of input and holds the same long single shots, renders in about half the time and costs less per second. The full Seedance 2.5 keeps a little more detail on complex scenes and offers 1080p, which Flash does not.

Does Seedance 2.5 Flash generate sound?

Yes. Turn audio on and dialogue, ambience and sound effects are generated in the same pass as the picture, at no extra cost.

Does the price change with resolution or clip length?

Yes. Seedance 2.5 Flash is priced per second of video, 480p costs half the per-second rate of 720p, and a longer clip costs more at that rate. The exact price is shown on the button before you generate.

Can I use my own images or videos?

Yes. Use a start frame and optional end frame, or upload up to 10 reference images and 5 reference videos. Reference mode and start/end frame mode cannot be combined in the same generation.
