Runway Gen‑4.5 hits all tiers – 10s shots, smoother cameras land

Runway’s Gen‑4.5 graduated from hype reel to everyday tool: it’s now the default video model for all subscription plans, not a gated preview. That means the same engine we covered yesterday for its 5–10s 720p clips and internal Elo‑board crown is suddenly what casual users see on first load. NVIDIA is amplifying the moment by slotting Runway alongside GPT‑5.2 on its GPU stack promos, signaling that Gen‑4.5 is built for heavy, production‑scale workloads rather than occasional “wow” demos.

Out in the wild, creators are mapping its personality. A cowboy riding through a modern city shows cameras that finally track motion cleanly instead of warping, while dance and neon‑city tests keep avatars, cars, and signage locked across multiple beats. At the edges, metallic snake‑robots and horror‑leaning contortion clips remind everyone the model will still hallucinate when pushed—which can be either a bug or a stylistic feature, depending on how weird your brief runs.

In parallel, InVideo’s new browser‑based Performances engine tackles a different piece of the puzzle: emotion‑true cast and scene swaps that preserve timing and micro‑expressions, hinting at a near‑future workflow where you generate worlds in Runway, then refit the acting without re‑shooting a frame.
