Check the link you posted -- it explains in all detail how to use the plugin. Quote:
"Simply add the plugin (.cslist) to the object from which you want to render (such as an Empty). You do not need the shader source files to use the plugin, they are included to enable people to change the plugin functionality if they want. The images will be saved to the "VaM\Saves\VR_Renders" folder. You can leave filename empty to use an automatic timestamp as the filename."
It renders a bunch of images, which you then have to combine to a video -- and this process is explained on the same site as well. Quote:
"You can merge the rendered image sequences to videos using Avidemux (GUI) , FFmpeg (command line) or another program of your choice.
Avidemux is probably easiest, you just drag and drop the first image in the sequence (xxx_000000.png) into the Avidemux window, alongside your recorded audio WAV file. You can also combine several different sequences into a single video by dragging in each one (assuming they are the same frame rate). From there you can set your encoding options, add additional audio and also apply various post-processing filters. Set your frame rate under Filters -> Change FPS. Typically you may want to encode in x265 or x264 codec to MP4 muxer, choose your bitrate quality level (CRF), and for very high resolution VR content (4K and above) you may need to set certain options like "IDC Level" (higher) and under tuning "fast decode" to make sure your video looks great but can also play back smoothly without lag.
For FFmpeg, you need to place the exe file into the "Saves\VR_Renders\" folder. Basic command line usage is as follows:
ffmpeg -framerate 60 -i output8k/output8k_%06d.jpg -i music.mp3 -c:v libx265 -tune:v fastdecode -level:v 6.2 -crf 20 output8k.mp4
"
It's all there in the link you posted, and I think it's a very detailed explanation on how to use the plugin.
