DaVinci Resolve — export the same edit for YouTube, LinkedIn, and Shorts

Overview

One source edit, three platform-specific exports, optionally automated with Python. The core principle: let Resolve's AI Smart Reframe do the reframing for you — do not manually keyframe Position for every clip when you change aspect ratio. Then save custom render presets so the next video is a one-click affair.

This skill also covers two merged JTBDs: auto-generating subtitles and batch-rendering with the Python API.

When to use

Symptoms:

• Need to ship the same video to YouTube + LinkedIn + Reels/Shorts/TikTok
• Need a vertical version of an existing 16:9 edit
• Need to add captions/subtitles to your video
• Want to automate "render this and that and the other" with a script
• Have multiple timelines to render in series and do not want to babysit Resolve
