Test the story without pictures
Play the opening and listen without watching. Can you tell what the viewer will learn, and does each section answer a distinct question? If not, revise the script before replacing footage. A faceless video generator can assemble a draft, but attractive scenes cannot rescue an unclear promise. For this tutorial, write the promise in one sentence and compare every section against it.

Match each claim to a visual
Watch again with sound. Pause whenever the narration names a tool, place, action, or result. Does the image illustrate that point, or is it merely related to the topic? Replace misleading or repetitive shots with material you have permission to use. If a claim needs proof rather than decoration, show a relevant demonstration or source instead of generic footage.

Check the viewer-facing finish
Review captions, audio balance, pacing, and the opening on a small screen. Correct names, numbers, and technical terms in captions; listen for clipped words or music that masks speech. Finally, inspect the exported file itself. Do not assume the preview and the final file are identical, and do not upload until the whole video plays as intended.
