Veo 3.1 4K Update Key Points

Industry Significance of Veo 3.1's 4K Update

The biggest highlight of this update is 4K resolution output, making Veo 3.1 the only mainstream AI video generation model currently supporting 4K output. In comparison, OpenAI Sora 2's maximum resolution remains at 1080p.

For professional creators, 4K means:

• Cinema-grade quality: Suitable for commercials, promotional videos, and other commercial productions
• Large-screen playback: Can be displayed without quality loss on TVs, projectors, and other large screens
• Post-production flexibility: 4K footage can be cropped while maintaining 1080p+ clarity
• Future compatibility: Meets streaming platforms' increasingly higher quality requirements

Veo 3.1 4K: Three Major Upgrades Explained

Upgrade One: 4K Resolution + Enhanced 1080p

Veo 3.1 uses advanced AI upscaling technology – it's not just simple pixel interpolation, but deep learning-based detail reconstruction. This means 4K output delivers:

• Sharper texture details
• More natural edge transitions
• More realistic lighting effects

Upgrade Two: Native 9:16 Vertical Video

This is a feature short-form video creators have been waiting for. Previously, creating vertical videos required:

1. Generating 16:9 horizontal video
2. Manually cropping to 9:16
3. Losing significant frame content

Now, Veo 3.1 natively supports 9:16 vertical output, allowing creators to compose directly for platforms like:

• YouTube Shorts
• TikTok / Douyin
• Instagram Reels
• Xiaohongshu (RED) videos

Upgrade Three: Enhanced Ingredients to Video

The "Ingredients to Video" feature has also received major upgrades:

Real-world Testing: When calling the Veo 3.1 API through API Yi (apiyi.com), even with short prompt descriptions, the generated character expressions and movements are noticeably more natural than before. Character appearance consistency across multiple shots in narrative scenarios has improved significantly.
