Minimal:
Find the strongest opening moment in my footage and start my explainer video with it.
Standard:
Open my explainer video with this. The question, or a surprising fact. Keep the hook under 3 seconds, then go straight into why it matters to them. No intro, no logo, no "hey guys".

Open my explainer video with this. The question, or a surprising fact. Keep the hook under 3 seconds, then go straight into why it matters to them. No intro, no logo, no "hey guys". Put a bold caption on the hook line. Before you cut, list the 3 strongest opening moments in my footage with timestamps so I can pick one.
Why these settings
- People typically decide to stay or scroll in the first few seconds, so the hook gets its own instruction.
- Saying what comes next (why it matters to them) keeps the video moving after a strong open.
- Asking for options with timestamps lets you choose the opening yourself.
Fixes
- Hook starts late. "Cut the breath and the half second before I start talking."
- Wrong moment. "Use the clip at 2:14 as the hook instead."
- The video drags after the hook. "Cut straight from the hook into why it matters to them, no pause."
FAQ
How long should the hook be on an explainer video? About 3 seconds, from the structure we use for this format. By then the video should already be into why it matters to them.
Can Vyra pick the hook for me? Yes. Ask for the strongest opening line. Ask for three options with timestamps if you want to choose.
