How to create an AI video for YouTube Shorts step by step

AI Video & Visuals


YouTube Shorts are one of the fastest ways to grow online today, but creating consistent, high-quality videos can still feel overwhelming. Editing takes time, filming takes effort, and not everyone has the skills to make their content look professional.

That’s where AI video tools are changing the game.

With modern platforms like AI video generators, you can now create short videos without traditional editing using advanced models, customizable formats, and even built-in audio. Platforms like Picsman.ai integrate multiple top-tier AI video models, making it easier than ever to go from idea to publishable short video.

Here’s a simple step-by-step guide to get you started.

Step 1: Choose the right format for your short video

Please set the correct format before generating the video. For YouTube Shorts, always use a 9:16 vertical aspect ratio. This allows the video to fill the screen and feel native to the platform.

You can also choose the resolution. 1080p is best for crisp viewing without slowing down your production.

Step 2: Choose the right AI model

Modern AI tools now offer multiple video generation models (such as Kling, Veo, and Sora-style systems) that are optimized for different outputs.

  • Use the standard model to balance quality and speed

  • If you want more dynamic, high-energy visuals, use the Pro model.

This flexibility allows you to tailor your content depending on your goals, whether it’s quick daily uploads or more sophisticated viral endeavors.

Step 3: Create a short scroll stop script

Short stories don’t need long scripts. In fact, the best-performing videos are often less than 15 seconds.

Use a simple structure.

For example: “Want to create better Instagram videos without editing? Try this AI trick.”

Step 4: Set the time period and generate

Typically, AI tools can generate clips in 3-, 5-, 10-, or 15-second segments. For short videos, shorter clips often perform better because they loop more naturally and capture attention.

you can:

  • Generate multiple short clips

  • Combine them into one fast-paced video

  • Experiment with pacing without manual editing

Step 5: Add sounds and captions

Many AI video tools have built-in sound options. Turn on audio and instantly generate clips with music and effects.

Still, always add a caption. Most users watch without audio. Clear, bold text increases watch time and engagement.

Step 6: Be consistent and test your ideas

The biggest advantage of AI video creation is speed. Instead of spending hours on a single video, you can quickly create multiple variations.

Different tests:

  • hook

  • Topics

  • visual style

Over time, you’ll learn what works and improve on it.

final thoughts

Creating YouTube Shorts used to require editing skills, expensive tools, and a lot of time. Now, with AI-powered platforms that offer multiple generations of models, flexible formats, and fast output, anyone can consistently create engaging videos.

The creators who win today aren’t necessarily the most skilled. They are the creators who can create, test, and adapt the fastest.

AI makes it possible.
