A savegame visualizer for Paradox Interactive's Europa Universalis IV that renders the political map mode over time as a configurable video using ffmpeg.
- Change
config/default.jsto match your game path and output preferences. See configuration for details. node app.js [path to your uncompressed save file]
Make sure EU4 is installed in the specified directory and ffmpeg is in your path. You can use ffmpeg to produce a gif: ffmpeg -ss 00:00:00.000 -i out/video1.mp4 -pix_fmt rgb24 -r 1 -t 00:00:10.000 output.gif
- Use a recent version of Node.js. Tested with 6.5.0, but should work in older versions.
- Should work with every version of EU4 (last tested with 1.19.)
- Make sure that the save file and the installed EU4 version match (otherwise provinces are not colored correctly)
- Mods that change the map are supported: change the appropriate paths in the configuration.
Change config/default.js to match your game path and preferences.
| Key | Description | Options |
|---|---|---|
| EU4_PATH | Absolute path to EU4 directory | Default is Windows x64 Steam directory |
| map.width | Width in pixels of output frames | Integer |
| map.climate, map.countries, map.definition, map.history, map.provinces | Relative path from base directory to data files. | Do not change in unmodded environment! |
| map.colors.sea, map.colors.wasteland | Colors used for oceans and wastelands respectively | Any RGB value in the format {red: int, green: int, blue: int} |
| map.colors.overrides | Colors by tag that should be used instead of default colors. | Format: 'TAG': {red: int, green: int, blue: int}. Use 'NAT' for Natives/uncolonized provinces. |
| video.framesPerPart | Split video in parts of X frames. By default, save2vid will split the output video into parts of fixed size to prevent a limitation of ffmpeg on Windows. | Integer. Default is 250. |
| video.parallelize | If multiple parts are produced, parallelize their creation. This will use significantly more resources, but reduce the processing time on more powerful systems. | true / false(default) |
| video.outputPath | Function that will be invoked to generate the name of video parts. | Will be invoked with the part's index as single argument. |
| video.options | Function that will be invoked to determine the options supplied to ffmpeg via videoshow. | Will be invoked with the map width as single argument. This allows to scale the video accordingly. See videoshow documentation for more options. |
