LinearBlur — primitive for transitions (glsl)

For AI agents: find the right skill in one call — curl -s "https://skills.varg.ai/api/search?q=<what the person wants>" returns the matching use case and the best skills with install commands, as markdown (Russian works too). Full index: https://skills.varg.ai/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the use-case page.

Both shots soften into a heavy blur, crossfade, then pull back into focus on the next

• Install: npm install gl-transitions
• Registry: gl-transitions · Framework: glsl · License: MIT
• Docs and preview: https://gl-transitions.com/editor/LinearBlur
• Source: https://github.com/gl-transitions/gl-transitions/blob/master/transitions/LinearBlur.glsl
• Example: https://skills.varg.ai/previews/lib-gl-transitions-linear-blur.mp4?v=50548 (Rendered by varg from the library’s own code (GL Transitions · rendered by varg))
• Time: Seek-safe. Time is an input, so frame N always renders the same. Drop it into a render as it is.
• Runs: local render, free
• Aspect: any

Prompt that renders it frame-exact

Add the "LinearBlur" transition from GL Transitions (by gre, MIT; https://gl-transitions.com/editor/LinearBlur, GLSL source https://github.com/gl-transitions/gl-transitions/blob/master/transitions/LinearBlur.glsl) between two calm scenes, or into a title card: 0.9 s, ease-in-out. A softer alternative to a plain dissolve that also hides mismatched framing. Remotion: npm install gl-transitions @gl-transitions/remotion @remotion/transitions, then a <TransitionSeries.Transition> with presentation={glTransition({ name: "LinearBlur", params: { intensity: 0.1 } })} and timing={linearTiming({ durationInFrames: 27, easing: Easing.inOut(Easing.cubic) })} (27 frames at 30 fps). HyperFrames: draw the GLSL on a full-frame WebGL canvas over the cut, with the outgoing and incoming frames as the from/to textures, and compute progress from the composition time, clamp((t − cutStart) / 0.9, 0, 1) through the easing; never from requestAnimationFrame or a timer, so every frame renders the same. ffmpeg's xfade can't run GLSL. intensity is the blur radius (0.1 default; 0.04 subtle, 0.2 heavy).
