SFX Picker - Cozer Motion SFX Library

148 curated sound effects across 10 categories, purpose-built for motion graphics, UI animations, and editorial video. Every file lives under assets/sfx/ in this repository and is ready to use in HyperFrames, ffmpeg pipelines, After Effects, or browser-based HTML compositions.

Before you start

Read references/catalog.md in full before picking any sound. It contains every filename, category, and recommended use case. Never invent a filename or path.

Step 1: Identify the visual moments that need sound

Map the animation to a list of keyframe moments. For each moment, state:

• What moves (element name, transform)
• When it moves (time in seconds from the composition start)
• The emotional intent (punchy, soft, glitchy, mechanical, organic)
