Choose one action worth showing
Do not squeeze the whole catalogue into one short video. Choose a property people can see in use: a folding bag, an adjustable lamp or packaging being opened. Describe the idea in one sentence. If that is difficult, narrow the subject before filming.
Break the idea into four shots
A useful sequence is situation, action, detail and next step. For an organiser: a cluttered desk, items being sorted, a close-up of the compartments and the finished arrangement. This is an editing example, not a universal sales formula. Show the real outcome and do not conceal important conditions.
Write pictures and words separately
Make a simple table with the shot number, what appears and what is said or written. A fastening may be shown while a brief caption explains its operation. Avoid filling the screen with a verbatim transcript. Make the key idea understandable without sound and use captions or subtitles for the explanation.
Capture enough material to edit
Stabilise the phone, prepare the product and clear the background. Record a little before and after each action. Film several takes of a difficult movement. Review the footage before wrapping: are fingers hiding the detail, is there glare, and does the item stay in frame?
Review the video as a complete answer
Show a draft to someone who has not read the script. Ask what it demonstrates and where to find the product. Check caption readability in the publishing preview and listen to the audio. If you use third-party music or clips, check that you have the rights needed for the intended use. Keep a clean edit and the original files.
