The Short Answer: Native Audio and 4K vs 15-Second Multi-Reference Takes
Because both Google Veo 3.1 and ByteDance Seedance 2.0 run inside Muvi Studio, you do not need two separate subscriptions. You route each scene to the model that suits it.
- Pick Google Veo 3.1 when the scene needs photorealism, careful lighting and native synchronized dialogue or ambient sound. It generates 4, 6 or 8 second clips at 720p, 1080p or 4K, which suits commercial B-roll and short dramatic takes. Veo 3.1 Fast offers the same options for cheaper drafts.
- Pick ByteDance Seedance 2.0 when the shot needs a longer duration (4 to 15 seconds), more aspect ratios (21:9, 4:3, 3:4 and 1:1 as well as 16:9 and 9:16), or reference locking with up to 9 images, 3 videos and 3 audio files. Seedance 2.0 requires the Pro plan; Seedance 2.0 Fast is available on all plans.
Many productions use both: Veo 3.1 for hero close-ups with sound, Seedance 2.0 for continuous wide takes and character storytelling.
