Video files - Gemini-Loboto3/RE2-Mod-SDK GitHub Wiki

Mod-sdk provides support for custom video files and mp4 compression for optimized size. In order to create compatible files, use ffmpeg and convert your movies by using the following command line:
ffmpeg -i test.avi -preset veryslow -vcodec libx264 -acodec aac test.mp4 -hide_banner
In order to make the new videos visible to the game, you will need to modify movie.xml to reflect wherever your video files are located.

Do not embed video files into 7z archives, they will not work and the game will complain about missing files or incorrect file access.
