I didn’t want to install the junk-ware that came with the time lapse camera I bought and I figured there had to be an easy way to do it with ffmpeg. Turns out there is. This assumes you have a series of images that look something like “foobar0099.jpg”
One problem I noticed is that if you are missing an image in the sequence the video will stop when it doesn’t find the next image in the sequence. The easiest fix is to rename all the files with a batch re-namer like NameChanger.
