Send animated PNGs to any LLM — every frame, not just the first

Steps

1. Install peepshow

   npm install -g peepshow

2. Run on the APNG

   Format auto-detected from extension + content.

   peepshow ./tutorial.apng

3. Feed frames to your LLM

   Drag the frame folder into Claude / ChatGPT or pipe the JSON to an API.

   peepshow ./tutorial.apng --emit json | jq '.frames[].path'

Why it works

APNG is the modern animated image format — losslessly compressed, supports transparency, widely used in tutorial assets and animated UI documentation. LLM vision APIs don't read it as motion. peepshow's format probe extracts every frame, drops near-duplicates, and emits a JPEG sequence.

When it helps

• Documentation hosted as APNG (technical tutorials, UI walkthroughs).
• Animated logos / loading states you want analysed.
• Asset archives where the source is APNG and conversion to MP4 isn't desired.

Pitfalls

• Transparency channel is dropped on JPEG export — pass `--format png` if you need it.
• Some APNG encoders use non-standard chunks; peepshow falls back to ffmpeg's apng decoder.
