BackgroundFrame the product,
not the desktop.
Padding, radius, shadow, crop, wallpaper, and motion backgrounds, compositor-style framing so every export looks intentional.

CodexThe problem
Every demo starts from scratch.
Re-doing background by hand on every take
Opening a full editor for a thirty-second demo
Agents that capture clicks but leave the polish to you
The fix
Background is built into the studio, not bolted on later.
01Compositor math
Padding scales from the shorter frame edge so 16:9 and 9:16 cuts keep proportional breathing room.
02Look controls
Radius, shadow, wallpaper, and chrome presets turn a raw share into a product marketing still.
03Motion backgrounds
Subtle animated beds behind the framed take, atmosphere without stealing focus from the UI.
In the studio
The real Screen Beaver UI, Background selected.
Rail, inspector, stage, and timeline, the same chrome you get in the Windows desktop app.
Set up once & you’re done.
Install the Windows app first, then MCP, then your agent.
01 Install the app
Download Screen Beaver for Windows. MCP only works after the software is installed and running.
Microsoft Store → install → leave open
02 Wire MCP
Install the CLI, then point any MCP-capable coding agent at Screen Beaver.
$ npm i -g @screenbeaver/mcp
03 Ship the demo
Background lands on the timeline, export locally.
Same demo. Different finish.
Toggle background on, watch Screen Beaver do the polish work between a raw take and a shippable cut.
