RimWorld: Create timelapse from Progress Renderer on Linux

Progress Renderer (Steam | GitHub) is a brilliant mod that takes a screenshot once a day, and dumps it into a folder.

The following bash script can be used to generate an mp4 timelapse of the screenshots. Simply specify a region to cut out of the screenshots, and some other parameters, and run the script in the working directory.

#!/bin/bash

###########################

# Video resolution (must be even)
SIZE=2272x1472

# Video FPS
FPS=10

# Region to export
CROP=4544x2944+4064+3360

# Output file
OUT=~/Videos/rimworldvid.mp4

# TMP Location
TMP=/tmp/rimworldvid
