Whenever we have big construction projects at work, I export footage from our CCTV system and time-lapse it.
But then one time I wanted to put two videos side by side. Difficulty that they were both variable frame rate (a quirk of the NVR, but meant that played at constant rate they wouldn’t line up).
It ended up with 5 copies of ffmpeg running at once. Because the most efficient way to create this monstrosity was 2 copies that stretched their input videos to 25fps (by duplicating frames), piped into two that ran the time lapsing, and both outputs into a 5th that assembled the video into one frame and encoded it.
I think you’d struggle to represent that level of kerfuckery in a GUI, to be honest.
I’ve done some truly horrible things with it.
