PRO NEW video v1.1.0 HyperFrames

Beat Lyrics

Beat-synced lyric videos for the vertical feed.

Builds a lyric video that actually lands on the beat. Upload a track and its lyrics, and the skill detects tempo and sections, times each line, and animates type that reacts to the music. Vertical is the default, with a landscape version for YouTube and artist pages.
