How to Create Vertical Video, Use a Teleprompter, and Use AI for YouTube After 50: Step-by-Step Answers

By Shelley Snyder, creator of Fifty Up Health and Beauty. I spent 40 years in the pharmaceutical and biotech industries before I taught myself how to build a YouTube channel from scratch — at 50+, with no film background, using an iMac and an iPhone. Below are the questions I get asked most about vertical video, teleprompters, and AI. The full step-by-step walkthrough, with exact clicks and screenshots, is in my ebook, Creating a YouTube Channel: Segment 2 — Creating a Vertical Video.

Why do I need a vertical video if I already made a horizontal one?

Horizontal video works for long-form YouTube content, but Shorts, Instagram Reels, and TikTok all require vertical orientation. You don’t need to reshoot from scratch — you can bring your existing footage into iMovie and reformat it for these platforms, which is exactly what this segment walks through.

How do I create a vertical video in iMovie?

Bring your footage into a new vertical timeline, then build it the same way you would a horizontal video — trimming clips, adding an establishing shot, layering in your logo, and adding titles and transitions. The mechanics are the same as horizontal editing; the difference is the frame orientation and how your shots need to be composed within it.

What is the Ken Burns effect, and why use it?

A still image sitting on screen with no motion can feel flat or dead. The Ken Burns effect adds subtle movement — the “camera” slowly pans or zooms across the image — which keeps a static photo feeling cinematic instead of frozen. It’s a small touch that makes an establishing shot feel intentional.

Do I need to worry about copyright when adding music to my video?

Yes — and it’s a bigger risk than most beginners realize. Using music that isn’t royalty-free can get your video removed, or more commonly, silently demonetized, meaning it stays up but earns you nothing. This applies to images too, not just music. Platforms like Instagram often recommend trending audio from popular artists, which can make it feel “safe” to use — it isn’t automatically. I use YouTube Studio’s audio library specifically because it lets me confirm a track is royalty-free before I ever use it.

How do I use a teleprompter when filming myself?

A teleprompter app lets you read your script naturally instead of stiffly reciting it from memory or losing eye contact glancing at notes. Write your script, load it into a teleprompter app, and use voice-tracking so the text scrolls as you read. You can also adjust the scroll speed to match your natural pace. The hardest part isn’t the app — it’s keeping your eyes on the camera lens instead of drifting across the screen, especially in horizontal orientation.

Which AI tool should I use — ChatGPT, Gemini, or Claude?

It depends what you’re doing. I use Gemini for video review and script writing. I use Claude for proofreading, business strategy, and figuring out tools I wouldn’t have found on my own. ChatGPT is useful too, especially since it comes free on Mac. None of the three does everything — the right one depends on the specific task in front of you.

What’s the biggest mistake beginners make when using AI?

Being too vague. If your prompt isn’t precise, the AI will fill in the gaps for you — and what it assumes may not be what you actually wanted. Being specific about exactly what you want isn’t optional; it’s the difference between AI saving you time and AI creating more work to fix.
