What does the "Adds video only" statement imply regarding the filmstrip icon in video editing?

The statement "Adds video only" regarding the filmstrip icon indicates that the function is specifically designed to incorporate video clips into your project without affecting other elements such as audio. This means that when you use this feature, it is focused solely on adding video content.

This distinction is essential in video editing since it allows for greater control over the multimedia components of a project. The ability to add video clips without altering any existing audio tracks or additional layers can be crucial for maintaining the intended sound design or audio narrative while enhancing the visual storytelling.

The context of the other options provides insight into why they don't align with the intended functionality of the filmstrip icon. For instance, the notion of creating only audio tracks or enhancing visual effects adds confusion about the icon’s purpose, as it does not involve those aspects. Similarly, the idea of replacing all current footage misrepresents the selective nature of what the filmstrip icon does—this feature is meant to contribute additional video, not supplant currently established work.
