A YouTube Shorts end frame with the channel large and the subscribe button morphing across a shared edge.
Shorts Subscribe is the last frame of a vertical video, where you have a second of attention and one thing to ask. Keep the channel name short enough to hold one line. The detail line is where an upload schedule belongs, if you actually keep one.
Keep the channel name short enough to sit on one line at vertical size. The detail line is for an upload schedule, new shorts every day, and only if you keep it. The kicker names the surface. The button morphs across a shared edge, so the colour should be visible against the plate.
YouTube Shorts Subscribe 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.
The full four seconds is about right. Shorts loop, so the end card also becomes the frame before the restart, and a viewer who missed it the first time catches it on the second pass.
Not on this comp. It is the subscribe press only. The vertical bell template is the follow-up, and cutting the two together makes a two-beat ask.
