Runway vs Seedance (Dreamina)
Trailers & marketing · checked · Compare different tools
Seedance (Dreamina) is the stronger pick for most game devs (82 vs 56). How we score
How they differ
How each one works, from its own docs.
Less a single model than a production suite: its own Gen-4.5 and Aleph editing plus many third-party models, an agent and a timeline. Luma is the closest suite rival. Kling, Seedance and Flow centre on their own models.
Best for: Trailer and social-ad production where you generate, edit and assemble shots in one place. Also mood reels and concept frames.
Uses very large reference sets to keep characters, style and sound consistent across long multi-shot clips. Kling and Flow take fewer references. Runway and Luma host Seedance as one model among many.
Best for: Turning character sheets, key art and voice-over into 15–30 second trailer or ad cuts with consistent characters.

Runway
- Artificial Analysis Video Arena AA-Video-T2V-Silent v2.1 (text-to-video, no audio): Runway Gen-4.5 (720p) #24 of 32
- Artificial Analysis Video Arena AA-Video-I2V-Silent v1.0 (image-to-video, no audio): Runway Gen-4.5 (720p) #25 of 81
- UD Same six prompts run through Veo 3.1, Gen-4.5 and Kling 3.0. Gen-4.5 was rated the clear winner for camera control, motion brush and character consistency across shots, second for realistic humans (good lighting, stiff arms), and behind Veo on prompt adherence. It also lacks native audio.
Seedance (Dreamina)
- Artificial Analysis Video Arena AA-Video-T2V-Silent v2.1: Dreamina Seedance 2.5 #5 of 32
- Artificial Analysis Video Arena AA-Video-T2V v2.1 (with audio): Dreamina Seedance 2.5 #5 of 30
- Artificial Analysis Video Arena AA-Video-I2V-Silent v1.0: Dreamina Seedance 2.0 720p #6 of 81
- Artificial Analysis Video Arena AA-Video-I2V v1.1 (with audio): Dreamina Seedance 2.5 #3 of 23
- YouTube: Dan Kuda AI, 'I Tested 3 AI Video Generators: Which Keeps Character Consistency?' Seedance 2.0 won clearly: dynamic scenes, natural motion and the character locked across every clip. Downsides: slowest (about 15 min per clip in explore mode), about 3x Kling's credit cost, and only 720p output needing an upscale per clip.
- YouTube: Ans, 'I tested Seedance 2.0 vs Kling 3.0 vs VEO 3.1' Seedance 2.0 won almost every one of 10 prompts (action, multi-cut dialogue with lip sync, emotion close-ups, prop interaction). Flaws: one clip with three hands, and a New York drone prompt came out looking like a Chinese city.
