How do I decide which moments in my video need sound effects?
Last updated September 26, 2026
Start with what viewers need to notice, understand or feel. Important actions, changes of location and reveals are useful candidates. A cut or movement does not automatically need an effect.
Watch the sequence and pick its main moments before adding sound. For a product demo, that might be opening the case, activating the product and showing the result. Give those moments a clear role, then decide whether quieter background detail would help connect them.
The invideo agent inside invideo Editor can analyse the video and place sounds around visible events. A useful brief is: “Emphasise these three moments and keep the smaller movements subtle.” You can review its choices and remove anything that distracts. The aim is a clear sequence of emphasis, rather than equal attention on every action.
