It will offer list of empires available, pick one number and
enter its number.
Run Stellaris and play your empire with autosaves enabled.
Each time a save game will be generated, map renderer will
try to produce an SVG for it.
When completed, you'll need to convert SVGs to video. This
can be done using Inkscape
and FFmpeg. Use the following
script (for Linux):
#!/bin/bash
SIZE=2160
for f in *.svg; do
inkscape -w $SIZE -h $SIZE $f -o $f.png
done
ffmpeg -y -framerate 10 -pattern_type glob -i '*.png' \
-c:v libx264 -pix_fmt yuv420p timelapse.mp4
What is SVG?
SVG stands for Scalable Vector Graphics. It is a
file format which is used in Internet for representing images
that need to be scaled without scaling artifacts (like maps).
It is supported by major browsers and can be edited with any
vector graphics editor such as
Inkscape.
