FFmpeg.guide is a GUI for creating complex commands - It has autocomplete with documentation embedded right in the UI, my goal was to make this feel somewhat like an IDE for FFmpeg. Finally, it does static analysis on your graph to make sure they're correct.
Hey PH, I've been hacking away on this tool to help me make and debug very complex filtergraphs and excited to launch it for everyone to use. I love how an IDE helps me write code faster and correctly by suggesting autocompletions and catching errors, so I wanted to do the same by making an IDE for ffmpeg commands. It's been a lot of fun hacking on this project, hopefully it helps you save a lot of time.
