An oversized notification bell that rings when the alerts button beneath it is pressed.
Aimed at people who already subscribed and still miss uploads. The bell loses about a third of its swing each half cycle, which is what a struck bell does. Use it as a follow-up to a subscribe prompt rather than a replacement for one.
The kicker addresses people who already subscribed, SUBSCRIBED ALREADY?, and the button labels are the before and after. The detail is the reason: so you never miss an upload. The bell rings when the button is pressed, and it loses about a third of its swing each half cycle, which is what a struck bell does.
YouTube Bell Vertical is built at 1080 × 1920, a 9:16 portrait frame, the shape Reels, TikTok, Shorts and Stories fill from edge to edge, and runs 4 seconds at 30 frames per second. It arrives in 0.9 seconds, holds for 1.9 and clears in 1.2, so cue it a beat before the moment it labels. Export it as an MP4 for a timeline or a feed, a GIF where video will not embed, or a MOV with an alpha channel to lay it over footage with nothing behind it. Renders go up to 4K, and the free plan exports at 720p with a watermark.
No. It assumes the subscribe has happened and asks for the next step. Use it after a subscribe card, or on its own for an audience you already have.
Because at vertical scale the bell is the message. A small bell beside a button is decoration; a bell that fills the top of the frame and rings is the point of the clip.
