Which one should you pick?
Pick Kling 4.0 if you need 1080p, clips as short as 3 seconds, or the lowest price for a 720p clip.
Pick Seedance 2.5 if you want cheap 480p drafts, control over sound, photos of real people (after verification), or to edit and extend a video you already have.
Not sure? Run the same prompt on both at 720p for 5 seconds. It costs 29 credits on Kling 4.0 and 39 credits on Seedance 2.5.
