How to make YouTube videos with AI

Generated b-roll is the real win

Most long-form videos stall because there is nothing to show while you talk. A handful of original eight-second clips — the object you are discussing, the place, the process — gives you cutaways that match your script exactly, instead of stock that nearly fits.

• Cutaways that match the specific thing you're describing
• Intro and outro plates in your channel's look
• Chapter transitions and background loops
• Thumbnail-adjacent shots for consistency

Render 16:9 for long form, 9:16 for Shorts

Generate in the shape you publish. A Short rendered natively vertical holds its composition; one cropped from landscape loses the sides where the movement lived. Both shapes take the same prompt, so it costs you nothing to do it properly.

Keep clips short and cut them together

Five to ten seconds per render. For a longer sequence, generate three clips of the same subject from different angles and cut between them — that reads as deliberate coverage, while one long generated take tends to drift.

Match your channel's look

Use the same style and light direction across every generated clip on a channel. Mixed styles make an edit feel assembled from scraps; one consistent look makes generated footage feel like your own camera.

Where not to use it

Do not use generated footage to stand in for evidence, real events, people who exist, or anything a viewer would reasonably assume was filmed. Label it when it matters, and follow YouTube's disclosure rules for synthetic content that could be mistaken for real.

Audio still comes from you

Generated clips are silent. Your voiceover, music and captions come from your editor — which is fine, because narration is where a YouTube video is actually won.
