Create a matching Browser Source, keep lyrics out of platform UI, and preview at phone size.
Frequently asked questions
Is 9:16 a TikTok-only feature?
No. It is a canvas ratio. TikTok LIVE is one publishing destination.
9:16
9:16 means a vertical canvas. StreamLyric documents 1080×1920 for TikTok LIVE style scenes. The Overlay still comes from YouTube Music playback, not from TikTok.
