The corner watermark that swells into a subscribe prompt, then retracts, the way the real one behaves.
YouTube Corner Watermark is the least intrusive prompt in the set, which makes it the one you can leave on for a long take. It has no cursor because the real control expands on its own. Two fields only: the label and the colour, because a watermark that carries copy is no longer a watermark.
Two fields only. The label is SUBSCRIBE or its equivalent, and the colour is red or your brand. A watermark that carries more copy is no longer a watermark, so resist the urge to add a reason. Let it swell and retract on its own.
YouTube Corner Watermark is built at 640 × 360, a 16:9 landscape frame, the shape of a YouTube video, a stream layout and most editing timelines, and runs 3 seconds at 30 frames per second. It arrives in 0.7 seconds, holds for 1.3 and clears in 1.0, 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 real corner watermark expands on hover and on its own timer, without a click, so the animation swells and retracts by itself. A pointer would misrepresent how the control works.
It sits in the same corner, so use one or the other. If your channel has the branding watermark switched on, this overlay would sit on top of it.
