Export MP4 with karaoke & effects baked in

Drop your own video, audio track, and .lrc lyrics file — then export a custom karaoke MP4. Karaoke animations, filters, and visualizers are all rendered into the final video.

Plays the full clip in real time — karaoke, filters & audio all captured.

This demo loads the exported extension runtime from the compiled build and attaches it to the visible local video, matching how the extension controls supported videos after install.
