# New AI: v3.1.11

We’ve updated our AI to version 3.1.11 in RADiCAL Core. Changes include:

- Improved fidelity (detail) and stability.
- Expanded input tolerance by allowing for a wider range of camera angles and aspect ratios.
- Fixed a common issue that produced a “hunching” effect in certain videos.

We recommend you continue to observe best practice, despite greater input tolerance and stability:

1. Single actor: **[details](/content/faq/recording-environment-people/index.html)**
2. Full body visibility (don’t leave the frame): **[details](/content/faq/recording-environment-people/index.html)**
3. Good calibration: **[details](/content/faq/recording-environment-people/index.html)**
4. Aspect ratio: 4:3 (landscape): **[details](/content/faq/recording-environment-people/index.html)**

**Fast updates:**

Note that results you have previously produced using an older version of the AI can be updated with a single click from the right-hand sidebar in your scene.

**Studio:**

The AI update will be rolled out to RADiCAL Studio in due course (check announcements).
