Ffmpeg

This is your FFmpeg cheat sheet for video production work, especially if you're building stuff with Remotion. It covers the workflows you'll actually need: converting GIFs to web-compatible MP4s, resizing and compressing videos, extracting audio, and preparing screen recordings for programmatic video. The Remotion-specific section is genuinely useful, it explains when to pre-process with FFmpeg versus using playbackRate, and shows how to calculate speed adjustments to fit demos into voiceover timing. Each command includes the flags you need and why they matter, like why you need yuv420p for browser compatibility or how to handle the atempo limitation for extreme speeds. Basically, copy-paste commands that work instead of debugging codec issues at 2am.
