A search bar animation is a short clip of a search field typing a query by itself and then sending it, as if someone were searching for it on screen. Editors use it to introduce a topic, to pose the question a video answers, or to make a joke out of what somebody would search.
This maker draws the field in the style of a search engine without copying any of them: a rounded field with a magnifier, a blinking caret and an arrow button in your accent color, with no company's logo. The query types at an uneven, human pace, a mouse pointer clicks the button, and three placeholder results shimmer in underneath.
Short searches read best, because the viewer has a second or two to take them in. A long one still works: once it reaches the end of the field it scrolls, the way a real search field does, so nothing spills out of the bar.
