 **Insta360Convert GUI** is a user-friendly desktop application designed to extract multiple defined perspective views (defined by pitch, yaw, and Field of View) from 360° equirectangular videos and export them as video clips or image sequences. It's a versatile tool for photogrammetry, VR content creation, visual effects, and various other video production workflows. This application supports English and Japanese user interfaces.
 
 **⚠️ Important Prerequisites: This application requires Python (3.9 or newer) and FFmpeg to be installed on your system, along with Tkinter (8.6 or newer, usually included with Python). Please see the "Requirements" section below for details.**
