Hi, I'm Nora. Lately I've been testing AI video tools for short explainer clips.

Seedance 2.5 is the one I keep coming back to: new accounts get free credits on sign-up, clips run 4-30s at 480p, 720p or 1080p, there are 6 aspect ratios, you can feed up to 50 references, and it supports local edits on an existing clip.
