Lunar Clipper

Search millions of Slippi replays. Turn the best moments into video.

A desktop app that imports your Slippi replay collection (Super Smash Bros. Melee), lets you hunt through it for exactly the moments you care about — a specific combo, a zero-to-death, an edgeguard — and renders them out as high-quality clips.

What it does

Point it at a folder of .slp files — a few hundred, or a few million — and build a filter chain to narrow them down. Each filter feeds the next, so you can go from "every replay I own" to "every Falcon knee that killed off the top on Battlefield" and export the result as video.

• Import .slp / .slpz replays in bulk, or drag a whole folder in
• Filter by game metadata — characters, stages, players, connect codes, dates
• Find combos with a combo parser: character-specific sequences (Falcon stomp → knee, Fox upthrow → upair), minimum hits, damage, kill confirms
• Find edgeguards with a dedicated parser that reconstructs the whole sequence — the launching hit, the recovery attempts, the denial — and scores how good it was
• Search frame data directly: action states, positions, stage zones
• Write your own filter in JavaScript if the built-ins don't cover it
• Render video via Slippi Dolphin's frame-by-frame dump + ffmpeg, at whatever resolution your hardware can take, with multiple Dolphin instances in parallel

It's backed by SQLite, so filtering stays fast across very large collections (the author's own database is ~2.8 million games).
