Developer creates Node script to render React Native Skia animation into video

The developer of the XNeuronal Android app needed to convert the app's animated brain visualization into a timed video. Traditional methods like screen recording or motion design tools were impractical or inaccurate. The solution involved creating a Node.js script that imports the app's existing geometry and drawing logic. This script renders the animation on a canvas and streams the frames directly to ffmpeg for video creation. The approach avoids duplicating code and maintains perfect synchronization with the app's visuals.
