Start with a mood
Warm, restless, dreamlike, slightly unwell. Describe the patterns, movement and colours you have in mind for the footage, the background or the text.
Create custom video effects with AI
Describe an effect. Get the code.
Describe the effect you have in mind and new shader code gets written for it. Then adjust the colours, patterns and movement in the preview until it looks like what you meant.
videoFn is a Mac video editor that Claude or ChatGPT can drive. Describe the video, watch it come together in the preview and give notes. If you'd rather fix something yourself, the editor is right there.

analog-static, embers, glow, vignette
Built-in shaders over the supplied cycling and drumming footage. Your agent can also write entirely custom shaders.
Effects nobody made a preset for.
Written from scratch
Rather than nudging a preset, the agent writes new shader code for your effect, checks how it renders and rewrites it from your notes.
Judge it in the video
“Less distortion.” “Keep the title clear.” Effects look different over real footage, so decide in the preview and adjust from there.
Also: animated text, youtube intro and everything else.
Free to make videos. €13.99 to lose the watermark.
Try the strange idea. You can always take the effect off.
