How to Make Vertical Videos with Google Veo 3 for TikTok & Reels

Short-form content thrives on vertical video. Whether you're creating for TikTok, Instagram Reels, or YouTube Shorts, a 9:16 format is essential to grab attention and fill the screen. But what if you're using powerful AI tools like Google Veo 3 to generate your content? Let’s walk through how to easily create vertical videos with Veo — and why AI platforms like Doitong make the process even faster.

Why Video Orientation Matters

A common mistake creators make is generating stunning AI videos — but in the wrong aspect ratio. Horizontal 16:9 videos might look cinematic, but they don’t perform well on mobile-first platforms like TikTok or Reels. Cropping them later often cuts off key visuals or ruins the composition.

That’s why it’s best to generate your AI videos in vertical format from the start.

Two Ways to Create Vertical Videos with Veo 3

1. Crop or Reframe Horizontal Output (Not Ideal)

If you already have a horizontal Veo 3 video, you can use a video editor to crop it vertically. This works, but you may lose important parts of the scene — especially if the subject isn’t centered.

Pro tip: Use blur padding or dynamic zoom tools to reduce the loss of visual quality.

2. Generate Vertical Videos Directly on Doitong

The easiest and most professional way? Just use Doitong’s built-in Veo 3 integration and choose the vertical aspect ratio (9:16) before you hit generate.

Whether you're using:

• Text-to-Video (write a prompt)

• Image-to-Video (upload a product or reference image)

…you can simply select “vertical format” during the setup process, and the AI will generate visuals composed specifically for TikTok, Reels, or Shorts.

No cropping needed. No guessing.

Bonus: Add Voiceovers and Music

Once your vertical video is generated, you can enhance it directly on Doitong by adding AI voiceovers in 32+ languages — or let the platform automatically generate synchronized audio and sound effects during the video creation process. Whether you want lifelike narration, ambient soundscapes, or cinematic audio design, it’s all built-in.

This means you can go from idea to polished short-form video in under 10 minutes, fully optimized for mobile viewing on TikTok, Reels, or Shorts.

Creating vertical AI videos no longer requires extra editing steps. With tools like Google Veo 3 and the intuitive workflow on Doitong, you can generate content that’s already formatted and ready for social platforms. Whether you're posting a product teaser, a storytelling clip, or a creative experiment — start with vertical in mind, and let the AI handle the heavy lifting.
