Vibe Video: code-rendered clips squeeze Kling 4.0 on two fronts
After Anthropic released Claude Opus 5.5, creators began using it — with Playwright and FFmpeg — to turn code-written HTML, Canvas, Three.js and GSAP animations into finished videos, a workflow the article calls "Vibe Video." Its strengths are deterministic, addressable frames and low cost (Opus 5.5 API at $4 per million input tokens and $20 per million output tokens), but it cannot render photoreal faces or simulate physics and cannot take reference video as input. On the professional side, Seedance 2.5 offers native 30-second clips and up to 50 multimodal references, Kuaishou's Kling 4.0 added 10-bit HDR, up to 15 reference assets and up to 10 keyframes in late September, and MiniMax H3 is a 33B open multimodal model at 2K/24fps with synchronized audio and video. The article argues general LLMs are capturing the planning stage while dedicated models become rendering engines, leaving Kling 4.0 squeezed between Seedance 2.5 and open-source H3.
It suggests value in AI video may shift toward planning and controllable editing, with code rendering and open weights squeezing closed video models from both sides.
