Build me a desktop app for creating nice-looking screen recordings for product demos. It should be a free, open-source alternative to something like Screen Studio, focusing on the core features that make those videos look polished.

The most important feature is the ability to record the screen or a specific app window and have an automatic, smooth zoom that follows my mouse cursor to highlight what I'm doing. It should also apply a subtle motion blur during pans and zooms to make it look really cinematic. I'll need it to capture both my microphone and the computer's system audio.

After recording, I'll need some basic editing capabilities. Let me trim the video, crop the frame to hide parts of my screen, and add simple annotations like text or arrows. I also want to be able to replace the boring desktop background with a solid color, a gradient, or a custom wallpaper image. When I'm done, it should let me export the video in different aspect ratios and resolutions.

Let's build this as a cross-platform app using Electron with React and TypeScript.
