What Seedance 2.5 does well

Seedance 2.5 is ByteDance's current video model and the one Kreavo uses most for UGC ads. Its standout feature is length: a slider from 4 to 30 seconds in one-second steps, where most models stop at 10 or 15. It outputs 480p, 720p or 1080p and supports six aspect ratios, including 21:9; when you start from an image, the clip follows that image's framing. Sound comes out of the same generation: voices, ambient noise and product sounds you describe in the prompt. Every recent Seedance 2.5 render we checked carries a generated audio track. Kreavo also offers Seedance 2.5 Edit, a video-editing mode that follows a source clip and lets you attach up to 9 reference images to swap the person or the product in an existing video, on selections from 1 to 120 seconds.

• Text-to-video and image-to-video in one model
• Any duration from 4 to 30 seconds
• 480p, 720p or 1080p output
• Sound generated with the video: dialogue, ambience, product sounds
• Aspect ratios 16:9, 4:3, 1:1, 3:4, 9:16 and 21:9
• Seedance 2.5 Edit: edit an existing video with up to 9 reference images

Seedance 2.5 vs other models on Kreavo

Against its own family, Seedance 2.0 Fast+ ($0.60 to $3.00) is the budget option for 4 to 15 second clips at 480p or 720p, and Seedance 2.0+ ($0.80 to $9.00) adds 1080p in the same range. Against other vendors, Kling 3.0 ($1.40 to $5.60 per clip) also generates sound but stops at 15 seconds, and Kling 4.0, Wan 3.0 and Grok Imagine also reach 30 seconds. Because everything runs in one Kreavo account, the same product and influencer can be tested across all of them.
