Name the job of the insert
An insert can show an object, establish location or make a sequence easier to follow. It can also be purely illustrative. Decide which role it serves before choosing it. If the viewer could reasonably mistake stock footage for the actual event, add context or use another visual. Attractive motion is not a reason to introduce false evidence.
Review automatic suggestions as drafts
Submagic documents both automatic B-roll and selecting or uploading media. A suggested clip still needs a relevance and rights check. We do not adopt the help page’s accuracy or virality claims. Match the visual to the specific sentence and inspect whether it changes the apparent meaning rather than simply sharing a keyword.
Keep a small asset record
Record the origin, permission or applicable license and the version used. A subscription does not automatically settle every use, person, logo or redistribution question. For important commercial uses, check the relevant terms or obtain qualified advice. This guide is an editing workflow, not legal clearance for a particular asset.
Check entry and exit timing
An insert that begins too early can appear to illustrate the previous claim. One that stays too long can hide a demonstration. Review both transitions with the spoken sentence and captions visible. Remove the insert when it does not make the point clearer. A clean uninterrupted source shot can be the more useful choice.
Prefer a precise label to a false illustration
If the speaker describes a hypothetical workflow, an original simple diagram labelled as an example may be clearer than stock footage of an unrelated company. Do not imply the stock subject is the customer or place discussed. A visual can help without pretending to document an event. Keep that distinction visible in the script, edit notes and any caption that might otherwise create an unintended factual association.
