If you are the owner of a TV or smartphone Xiaomi and stumbled upon the settings on a mysterious parameter XFF (Or Xiaomi Film Frame, which is probably the question of what it is and why it is needed, and it has been appearing in the firmware of the brand’s devices since 2022, but the official documentation about it is not. As a result, users either ignore the feature or turn it on at random – which is not always right.

In practice. XFF — This is a proprietary development by Xiaomi, designed to improve video playback through dynamic frame processing. It works differently than standard frames. HDR It's called Dolby Vision, and it can improve the quality of the image, and it can worsen it if you don't set it up properly:

What is it? XFF Xiaomi: A Technical Explanation

XFF (Xiaomi Film Frame is a video post-processing technology that analyzes each frame in real time and applies dynamic correction to it. HDR, which works with fixed brightness and contrast parameters, XFF It adapts to the content of the scene:

• 🌑 In dark scenes, she raises the level of detail in the shadows without highlighting the light areas.
• ☀️ In bright shots (such as beach scenes) reduces overexposure by preserving cloud or sand textures.
• 🎭 When watching movies with frequent lighting drops (thrillers, action films) smooths out sharp transitions between frames.

The technology uses machine learning algorithms trained on thousands of hours of video from different genres, according to Xiaomi engineers, XFF Especially effective when viewing content in resolution 4K low bitrate (e.g. streaming services) where standard image enhancement techniques often yield artifacts.

It is important to understand that XFF — It is not a replacement for Dolby Vision or HDR10+, It's an extra layer of processing, and it can run on top of these standards, but it sometimes conflicts with them. XFF Dolby Vision on some models of Xiaomi TVs is observed excessive color saturation.

What devices Xiaomi has on XFF

Function XFF Xiaomi has been in firmware for a relatively recent time, with first mentions dating back to 2022, and is now available on the following types of devices:

On older models (e.g. Mi) TV 4S or Redmi Note 10 functions XFF It was only added to devices with MediaTek Dimensity 9000 processors.+ Qualcomm Snapdragon 8 Gen 2 and later, because the technology requires significant computing resources to process video in real time.

To check if your device supports XFF, Go to the image settings (on the TV) or the player settings (on your smartphone) and look for the Xiaomi Film Frame or Dynamic Frame Improvement. If it is not, your model is not compatible.
