Seedance 2.0 vs Kling 3.0 vs Veo 3.1
Direct specs and workflow fit for Seedance 2.0, Kling 3.0, and Veo 3.1. See duration, resolution, and credit costs side by side.
TL;DR
Seedance 2.0 gives 8-second 1080p clips at 24 fps for 12 credits. Kling 3.0 produces 4-second 720p at 60 fps for 9 credits. Veo 3.1 yields 5-second 720p with depth maps for 10 credits. Pick Seedance for length, Kling for loops, and Veo for physics.
Core differences at a glance
Seedance 2.0 generates 1080p clips up to 8 seconds from text prompts. Kling 3.0 handles 4-second 720p outputs with strong motion consistency. Veo 3.1 produces 720p videos at 5 seconds and excels at physics simulation.
How each model processes prompts
Seedance 2.0 breaks text into motion tokens then renders frame sequences at 24 fps. Kling 3.0 uses a diffusion backbone that iterates over 50 steps for temporal coherence. Veo 3.1 applies a transformer that predicts optical flow across 30-frame windows.
Seedance 2.0 pipeline
It accepts prompts up to 120 tokens and references a single style image. Output files are MP4 at 24 fps.
Kling 3.0 pipeline
Kling 3.0 requires a 15-second seed clip for reference-to-video runs and exports H.264.
Veo 3.1 pipeline
Veo 3.1 ingests first-to-last frame pairs and returns 720p files limited to 5 seconds.
Concrete input and output specs
All three accept 1080p reference images. Seedance 2.0 returns 8-second clips at 24 fps with 48 kHz audio tracks. Kling 3.0 limits runs to 4 seconds but supports 60 fps. Veo 3.1 caps at 5 seconds yet adds depth maps at 720p.
Users often start with text-to-video to test base motion before moving to image-to-video for reference control.
Where each model fits real workflows
Seedance 2.0 suits short social clips that need quick turnaround. Kling 3.0 fits character animation sequences that repeat motion across shots. Veo 3.1 works for product demos requiring accurate physics like bouncing balls.
