RiotGames/leaguedirector — reverse-engineered prompt

Build me a Windows only desktop app for making cinematic videos from League of Legends replays. I want it to detect my game install, connect to a replay automatically, and give me simple controls for replay playback and speed. It should support a free first person style camera, let me lock the camera to a champion or minion, and let me hide or show things like the HUD, health bars, and notifications.

I also want the visual controls people use for montage shots, like field of view, clipping distance, custom skyboxes, shadow direction, fog, and depth of field. Please include a sequencer where I can record keyframed camera moves and visual settings on a timeline, edit them, undo and redo changes, tweak blending, and save or load sequences.

It should be able to export captures as webm or png, and let users customize key bindings. Make it runnable from source with the included start scripts, and feel free to look up current docs online if you need to.
