Because both Google Veo 3.1 and ByteDance Seedance 2.0 run inside Muvi Studio, you never have to pay for two separate subscriptions. You simply route each scene to the model that handles it best.

- Pick ByteDance Seedance 2.0 when your shot requires extended scene duration (4 to 15 seconds), ultra-wide or custom aspect ratios (21:9, 4:3, 1:1), or multi-character reference locking via Omni-Reference (up to 9 image anchors).
