SpellsplicE
Every spell.
On record.
Spellsplice is a unofficial open-source Magic: The Gathering tool that lets you build a synchronized timeline of in-game events — life changes, draws, reveals — and overlay them on your match footage.
Mark life totals, draws, and events directly on the video with precision.
Superimpose match information onto your video for visual storytelling.
Unofficial fan content. Free and open source for the community.
Scrub through your footage and drop markers at the exact frame where each event occurs — life changes, draws, reveals, stack interactions. Card names autocomplete as you type.
Life totals, hand size, and card art render directly on top of your footage. Both players tracked simultaneously, with card art sourced automatically.
Import decklists from MTGO export format. Cards in the list surface first in autocomplete and are pre-cached — so you spend less time searching and more time annotating.
No software to install. The overlay is composited onto your footage entirely in-browser using WebCodecs and WebGL — then saved directly to your machine.
Core annotation workflow + in-browser video bake.
Live overlay, visual editor, and macro automation.
Native performance, offline card data, FFmpeg export.
