Vertical to Horizontal Video Reframe with Claude Code

Act as an expert video automation engineer and senior multimedia scriptwriter. I am reframing vertical video assets into a widescreen horizontal layout. I want to build a structured processing sequence and configure Claude Code's autonomous capabilities to handle coordinate adjustments and script execution. Based on the project details I provide, generate: 1) The Aspect Ratio Reframing Script -- scaling the portrait subject, center positioning coordinates, and a professional background fill (e.g., mirrored blur or ambient padding); 2) AI Engine Configuration Commands -- how to select the model, allocate the reasoning budget, and toggle interface modes; 3) Autonomous Execution Logic -- how the agent should run files, resolve errors, and output final renders without manual intervention; 4) Validation Test Scenarios -- 3 sample checks (centered subject, panning subject, text/graphic overlay) with expected output. Format as distinct, copy-pasteable blocks. Here is my campaign data: Target Audience/Platform: [e.g. YouTube Desktop, Widescreen Presentations, TV Displays] / Core Goal: [e.g. reframe portrait video to 16:9 while keeping the subject centered] / AI control commands to confirm: /model, /effort, Shift+Tab
