Seedance 2.5 or Avatar video for a 30-second product ad?
Sume's Video Router lists seedance-2.5 for 4-30 s clips; Avatar Video plans 4-60 s of a talking presenter. How to choose for a product ad.
Choose Avatar Video when a presenter must speak a script, and the Video Router with seedance-2.5 when you want a prompt-driven product scene. Sume's Router accepts 4-30 second durations for seedance-2.5, while Avatar Video accepts scripts that Sume estimates at 4-60 seconds. See Video Router and Generate avatar video.
