So basically this[0] with a crossfade[1] between frames? Which would be (by stitching examples together)

  ffmpeg -framerate 1/5 -pattern_type glob -i '\*.jpg' -pix_fmt yuv420p -filter_complex xfade=transition=fade:duration=2:offset=2 out.mp4

(1 jpg image per 5 seconds with a 2 seconds crossfade in between)

I was just about to write that exact same command from my flawless recollection of stitching examples together from that wiki! But you beat me to it.

Honestly, I'd love a podcast called "Quinecast" where each episode consists of hosts talking in detail about the ffmpeg flags that were used to create the podcast.

Yeah, although I'd be surprised if this isn't what Shotcut does (it uses ffmpeg).
