Why it matters
Most people decide in that window. A great video with a slow start gets judged by the start.
Example
Opening on the burnt pan with “This is why your rice sticks” beats opening on “Hey guys, today…”.
Common mistake
Treating the hook as only the spoken line. The first frame and the on-screen text are part of it, and they have to agree.
How to use it
Write the hook last, once you know exactly what the video delivers, then check all three layers together: the picture in the first frame, the line you say and the words on screen. Each should make the same promise, and the rest of the video has to keep it. If you can, start with the most interesting moment you filmed rather than the beginning of the process.
