How they differ
How each one works, from its own docs.
Built on Google's Veo and Omni models around a shot workflow (frames, ingredients, extend, Scenebuilder). Omni adds chat-driven edits of uploaded footage. Kling and Seedance are single-generator rivals. Runway and Luma are multi-model suites.
Best for: Storyboarding and producing short trailer sequences shot by shot, keeping characters consistent with ingredient images.
Works from video and times sounds to on-screen action. ElevenLabs and Stable Audio make SFX from text only; Suno and AIVA focus on music.
Best for: Fast sound passes for trailers, gameplay capture and cutscenes, plus ambience loops and foley drafts.

- Artificial Analysis Video Arena AA-Video-T2V-Silent v2.1: Gemini Omni Flash 1.1 #8 of 32

- UD Veo 3.1 was rated best on prompt adherence (87% vs 72% Runway, 68% Kling, quoting a 'Pixflow' benchmark) and praised for native dialogue/SFX/ambience in one pass, saving time on narrated clips; but it sometimes produced an 'AI face' and had the wrong number of fingers in 2 of 5 generations. Recommended for marketing and narrated content.
- YouTube: Dan Kuda AI, 'I Tested 3 AI Video Generators: Which Keeps Character Consistency?' Veo 3.1 'disappointed me completely': unnatural motion, the character barely held to the references, extra first/last-frame steps, same cost as Seedance for worse results, and a rooftop-sniper scene was blocked by safety filters. Verdict: skip it (in Runway).
- YouTube: Ans, 'I tested Seedance 2.0 vs Kling 3.0 vs VEO 3.1' Veo 3.1 came third on most of 10 prompts (poor fight choreography and dialogue scenes, odd extra actions, wrong product colour), with one good POV/weather result; the tester notes Veo is limited to 8 s per generation.
- Android Police: 'I tried Gemini Omni, and I wasn't ready for how futuristic it felt' Hands-on with Gemini Omni (Gemini app, paid tier): templates, a physically accurate camera-sensor explainer, photo-to-video with lip-synced singing, and conversational edits that kept continuity. 'I went in skeptical, and I came out thoroughly blown away.'
