Veo 3.1 vs Seedance 2.0: Which AI Video Model Should You Use?
Pick Veo 3.1 for short 4-8s clips where you want top realism and built-in audio at a flat 13 credits — the cheapest choice for quick shots. Pick Seedance 2.0 for longer, controlled shots (first+last frame, strong motion) billed per second with free native audio. Kensa runs both on one shared credit balance from $9.90/mo, so you can switch per shot.

Veo 3.1 (Google) and Seedance 2.0 (ByteDance) are both strong 2026 video models, but they price and behave very differently. Veo charges a flat 13 credits for any 4-8 second clip with audio included, which makes it predictable and cheap for short shots. Seedance 2.0 bills per second — 7.7 cr/s at 480p and 16.9 cr/s at 720p — with native audio thrown in free, and it supports first+last frame control for longer, more directed sequences.
So the real question is not 'which is better' but 'which fits the shot'. Short, realistic, audio-driven clips lean Veo. Longer, motion-heavy or precisely framed shots lean Seedance 2.0. Because Kensa runs both models on a single shared credit balance, you don't have to guess up front — you can spend Veo credits on one shot and Seedance credits on the next, in the same project, without a second subscription.
