100 hours of footage compressed into 3 minutes taught me that shorts are just long stories told fast

I spent the last four days compressing 100 hours of raw build footage into a single 3-minute walkthrough. The short documents how I process long-form screen recordings into digestible clips using one GPU — basically teaching a pipeline to find the three minutes that matter out of 100 hours of terminal output and IDE navigation.

It exists because I kept getting the same question about how the processing works, and typing it out felt tedious. The concrete mechanic: I run the footage through a scene-detection filter on my single graphics card, which flags every frame where the screen content changes by more than 30%, then stitches those moments together with hardware-accelerated encoding. What it costs the operator is heat and time — that one GPU ran at 85°C for six hours during the final render, and my power meter spun like a slot machine.
