# Cut a Steam trailer from your gameplay

Turn recorded gameplay into a paced Steam trailer cut.

デモは近日公開。コンテンツチームが収録し次第、ここにループ映像が入ります。

実行イメージ

Cut a Steam trailer from my last playtest recording.

Summer does not have a gameplay-capture or video-cutting tool connected yet, so I cannot pull frames from a recording or assemble a cut.

Coming soon: once a capture tool ships, this preset records Play mode directly and hands the footage to a trailer-cut workflow.

実行する

Claude DesktopClaude CodeCursorCodexCLI

1. 1Open Claude Desktop with the Summer Engine MCP server connected (see /mcp if it is not connected yet).
2. 2Paste the prompt below and send it.
3. 3Watch the agent call the Summer Engine MCP tools, then check the result in Play mode or the generated files.

Coming soon

Summer's MCP surface has no gameplay-capture or video-editing tool yet, so an agent cannot record or cut real footage end-to-end. Once a capture tool ships, this reuses summer\_screenshot for stills and adds real recording.

Cut a Steam trailer from my recorded gameplay: pick the strongest 30 to 60 seconds, pace the cuts to the hook-build-payoff structure Steam trailers use, and export it at 1920x1080.

If Summer Engine is not connected yet, connect it first: read https://www.summerengine.com/mcp, install and set up Summer, then run this.

Not connected yet? [先に Summer Engine MCP をセットアップ](https://www.summerengine.com/ja/mcp), then come back and run this preset.
