There will be signs

The line is the whole personality of the post: "I won't tell anyone when I make it, but there will be signs." TechHalla then shows the signs, a cinematic sequence, and puts the Magnific prompts underneath.

That combination is why it is here. A moody shot with no method is an ad for a mood. A moody shot with the prompts is a method, and the joke — I won't announce it, but here is exactly how — only works if the picture earns the secrecy.

Thirty seconds is enough. Either the signs look like a film someone would hide, or they look like a preset. The prompts let you tell the difference.
