Depending on your Xiaomi model, the options available may include:

• 🎥 720p (HD) — Minimum quality, suitable for saving space
• 📺 1080p (Full HD) — Optimal balance of quality and file size
• 🖥️ 1440p (2K) — Available on flagships (Xiaomi 13 Pro, 14 Ultra)
• 🎬 2160p (4K) — Maximum quality, requires a lot of memory
• 🔄 Auto - Automatic selection (not recommended due to instability)

Note: on some models (e.g. Redmi Note 11) when selecting 4K Option 60 may be missing. FPS. This is due to the limitations of the Qualcomm Snapdragon processor in budget smartphones.

💡

If the list does not have the necessary permission, check if the mode is turned on. HDR10+ or LOG These modes often limit the formats available.

2. Additional settings: frame rate and bitrate

Resolution isn't the only thing that affects video quality (FPS) And bitrate. On Xiaomi, these settings are sometimes hidden in the submenus.

To find them:

1. Open the chamber. → Go to video mode.
2. Touch the icons ⚙️ (Or the sleeves in the upper corner.
3. Select Video Settings or Resolution and Frame Frequency.
