Show the interesting part first
Suppose you filmed a chair being restored. The most useful opening might be the damaged seat beside the finished one. A slow pan across the workshop can come later, once the viewer knows why the work matters.
Look through the footage for a question the pictures can answer. How did the stain come out? What fits inside the bag? Why does the hinge fold that way? A specific visual question gives your cut direction without needing an exaggerated promise.
Write for the footage you have
Choose the clips that show the answer. If the important action happens near the edge of a wide shot, a vertical crop may hide it. Ask for the action to stay visible and check the output on a phone. Framing should serve the demonstration, not merely fill the screen.
In Shorty, request a vertical edit from your selected clips. Describe the opening, pacing, necessary text, and ending. You can add a reference when it helps explain the feel, but the reference cannot supply an action you did not record. Keep the claim and the visuals tied to your own material.
Judge the edit without the trend
Watch with the sound off. Is the subject obvious? Is the text readable? Does the last shot pay off the first? Then listen for music or effects that make speech harder to follow. Remove anything that obscures the point.
The best editor for you is the one that can produce this kind of clear result with manageable review. No tool can promise distribution or virality. Try one representative video, request a real correction, and compare the finished version with the effort you put in.
A brief to adapt to your footage
Example direction. Replace the subject, shots, and wording with your own.
Make a 20-second 9:16 restoration video from these clips. Open on the before-and-after view, then show the two actions that explain the change. Keep the hands and seat visible. End on the finished chair. Use plain, short labels where needed.
