Model deep-dives
Sora 2 (OpenAI)
What it is: OpenAI’s newest video+audio model with stronger physics, realism, and controllability than prior systems now packaged in the Sora iOS app (invite-only at launch, US/CA). Clips in-app are ~10 s; all downloads carry a visible moving watermark and embed C2PA provenance metadata. Cameos let consenting users appear in others’ creations, with revocable permissions.
Why it’s different:
- Physics-aware motion + better object permanence.
- Native audio (dialogue, SFX, music) aligned to visuals.
- Safety stack: prompt/output moderation, blocked public figures, teen safeguards, watermarking/provenance.
Best for: premium ads, explainers, pre-vis, and social creation where realism + audio sync matter most.
Modes: Text‑to‑Video and Image‑to‑Video are both available (including in Sora 2 Pro). Users can upload their images to create videos from those images; audio is generated by default (can be muted if needed).
Example prompt (marketing):
“Vertical 9:16, 10-second smartwatch teaser; macro knit and sapphire glass, neon rim light, ‘Smarter. Faster. Better.’ kinetic text at 0:06, whoosh + bass hit on each word; studio reflections; end logo lockup.”
Veo 3.1 (Google/DeepMind)
What it is: Google’s upgraded cinematic video generator with native sound effects, ambience, and dialogue now adding granular control layers. Public entry points include Gemini, Google AI Studio, and the VosuAI Veo 3.1 image-to-video experience at. Clips remain ~8 s by default, tuned for high-fidelity polish.
What’s new in 3.1:
- Ingredients: combine up to three reference images to anchor character, environment, and props simultaneously.
- Match your style: upload a dedicated style reference image and have Veo mirror the look across outputs.
- Add / Remove Object + Outpainting: Nano Banana-style scene editing to inject new elements, erase distractions, or expand beyond the frame without leaving Veo.
- Character Controls: drive facial expressions or full-body performance, turning the model into an animation “buddy.”
- Reimagine motion: sketch motion paths so objects follow precise trajectories.
- Camera Control: steer shots with timeline keyframes (the 4:13 demo sequence showcases pan, tilt, and push control).
Strengths:
- High prompt adherence, cinematic texture, and now fine-grained motion/camera direction.
- Native lip-sync/music alignment plus reference-driven styling for franchise consistency.
Limitations: ~8-second defaults and availability/paywalls via Google tiers.
Best for: storytellers needing polished beats with director-level control over style, character performance, and camera motion.
Example prompt (dialogue + pathing):
“16:9, two friends at a ramen bar; shallow depth-of-field, steam in foreground; warm tungsten; draw motion path for a passing waiter; subtle room tone + clinks; one-line dialogue: ‘We did it.’ Natural lip-sync.”
Runway (Gen-4 & Gen-4 Turbo)
What it is: A creator platform (web) for generation and editing. 2025 brought Gen-4 (consistency across scenes/characters) and Gen-4 Turbo (fastest model, all plans). Pricing spans free → enterprise; credits convert to seconds.
Strengths:
- Continuity/consistency across angles (ref images).
- Video-to-video restyle, expand-video, editor, integrations.
Limitations: realism has improved but still trails Sora/Veo at the bleeding edge; audio is workflow-added, not native model audio.
Best for: social creators/teams needing an all-in-one pipeline (prompt → edit → export) and rapid experimentation.
Example prompt (social ad):
“Square 1:1, coffee cold brew pour over ice in slow-motion; macro bubbles, condensation; airy summer palette; end with bold price tag; fast cut rhythm 120 BPM.”
Wan 2.5 (Alibaba ecosystem)
What it is: The latest Wan iteration seen across Alibaba-linked portals, described as producing 10-second 1080p, 24 fps clips with synchronized audio (text-to-video and image-to-video). Public materials frame 2.5 as a preview/next step beyond earlier Wan 2.1. (Note: branding and access may vary by portal/vendor.)
Strengths: swift short clips with native audio; pragmatic for social spots and quick teasers. Kuaishou’s Kling 2.5 Turbo is a parallel China-market rival focused on speed and cost useful context when comparing ecosystems.
Limitations: English-language docs are sparse; global access and terms vary.
Best for: short, audio-synced clips where turnaround and cost matter more than ultimate fidelity.
Example prompt (teaser):
“10-sec 16:9 sneaker hero shot; rotating tabletop; glossy reflections; electro whoosh on 0:03 swoop; end tag ‘Drop Friday.’”
PixVerse
What it is: A freemium AI video platform (web/app/Discord) popular with indie creators. Multiple model versions (e.g., v4.5 → v5 in listings), daily credits, and styles (realistic, anime, 3D). Great for fast social clips; no native model audio.
Strengths: easy onboarding, generous free credits, quick viral-style videos, anime focus.
Limitations: shorter/variable durations; watermarking on free; realism/physics below top tier.
Best for: hobbyists/social creators and anyone testing AI video for free.
Example prompt (anime short):
“Vertical 9:16 anime dance loop under neon signs; parallax city lights; cel-shaded; energetic camera push-ins; three-beat pose cycle.”
