I Built a Free AI Pipeline for YouTube Shorts Using FFmpeg

I set a constraint before I had a plan. No subscriptions. No credits ticking down in the background. No platforms deciding how many videos I was allowed to make this week. If I was going to produce YouTube Shorts at any real volume, it had to run locally, it had to be repeatable, and it had to cost nothing beyond the machine I was already using. That requirement stripped the landscape down fast. Most “AI video tools” disappeared the moment you looked closely. What was left wasn’t polished. It wasn’t friendly. But it was honest. _Raw utilities. _ Things that do exactly what you tell them and nothing more. That’s how I ended up back at FFmpeg- not as a last resort, but as the only thing in the room that wasn’t trying to meter my output... and that could surprisingly be used by any AI model I threw it at. The Constraint That Actually Mattered I wasn’t trying to build a better editor. I was trying to solve something much narrower and more stubborn. I wanted a way to generate YouTube Shorts
