KPop-Pro
Stra.ai
The core module of a K-Pop learning app — bakes the original audio and lyrics onto a user's self-recorded clip and exports a new video.
Visit the site— Where we began
Foreign learners studying Korean through K-Pop weren't satisfied with watching — they wanted to walk away with their own performance video.
— How we worked through it
Customizable lyrics — font, position, style — sit over the user's clip; FFmpeg encoding renders a new video with the original audio. Editor UI and module live together in one Flutter build.
— What followed
Past 500K downloads on Android alone. Our single video module became a core path through the app.
