Description

When exporting a ~16-minute recording on Windows 11 at either 1080p or 4K, Cap rapidly consumes all available VRAM and system RAM. This immediately causes the application to freeze or the entire display to go black. Critically, once this happens, the Cap process becomes completely unkillable (Task Manager and taskkill fail), forcing a hard reboot.

As a workaround, I attempted to manually concatenate the raw .mp4 and audio fragments into a single file, but discovered that the cursor overlay is not baked into the raw segments.

Export should complete within normal memory limits. If export fails, the app should gracefully crash and remain terminable without locking up the OS.

Is there any method to extract or render the original recording files with the mouse cursor included? I just need a reliable way to salvage these 16-minute recordings

Reproduction

1. Record a session for approximately 16 minutes on Windows 11.
2. Open the recording in Cap.
3. Start export at 1080p or 4K.
