What frame format is better to choose on Xiaomi: a detailed guide of 4:3, 16:9, 1:1 and 21:9

Xiaomi’s smartphone frame format is not just an aesthetic choice, but a strategic decision that affects the quality of the shot, social media compatibility and even post-processing capabilities. With the development of cameras in the Redmi, POCO and Xiaomi’s flagship 14/13 Ultra range, the number of available formats has grown: classic 4:3 and 16:9, square 1:1, cinematic 21:9, and in some models even 18:9 or 2.35:1.

In this article, we’ll look at the unique features of each format using specific Xiaomi models, including the impact on resolution, viewing angle, and artifacts when shooting. You’ll learn why 4:3 remains the standard for photographers when 16:9 loses 21:9 in video, and how to circumvent format restrictions through manual settings. And also a compatibility test with Instagram, TikTok and YouTube to help avoid clipping when posting.

What is the format of the frame and how it affects the shooting

The format of the frame determines the ratio of width to height of the image. For example, 4:3 means that for every 4 units of width there are 3 units of height.

  • πŸ“ End file resolution: With the same number of megapixels, 16:9 will give you less pixels in height than 4:3.
  • πŸ‘οΈ Viewing angle: wide formats (21:9) can crop the top/bottom of the frame, narrowing the vertical view.
  • 🎬 Platform Compatibility: Instagram Stories requires 9:16, YouTube recommends 16:9.
  • πŸ–ΌοΈ Post-processing: 1-1 square is easier to fram, but limits the composition.

On Xiaomi smartphones, the format is selected from the camera menu – usually in the Settings β†’ Photo / Video format. However, in models with Leica optics (for example, Xiaomi 13 Ultra), additional profiles are available, where the format may depend on the chosen shooting style (Leica Authentic or Leica Vibrant).

⚠️ Note: In Pro mode, some devices will lock the format to 4:3, even if the main menu is different, due to the limitations of processing algorithms. RAW.

Comparison of frame formats on Xiaomi: pros and cons

To choose the best format, compare them by key criteria: Below is a table with characteristics for popular Xiaomi models (data is relevant for MIUI 14/15 and HyperOS firmware):

For example, on the Redmi Note. 12 Pro+ filming 4:3 You'll get it. 9248Γ—6936 pixels, and in 16:9 β€” only 9248Γ—5208. The difference 20% pixel height is critical if you plan to crop the photo later or print it in large format.

Which format is best for photos on Xiaomi

4:3 is the gold standard for three reasons:

  1. Maximum resolution: Xiaomi sensors are optimized for this ratio. For example, 8192Γ—6144 is available on the POCO F5 Pro at 4:3, and 8192Γ—4608 is available at 16:9.
  2. Frame flexibility: You can always trim 4:3 to 16:9 or 1:1, but not vice versa.
  3. Fewer artifacts: When shooting at 16:9 or 21:9, the camera programmatically crops the frame, which can increase noise in dark areas.

The exception is social media, and if you only post photos on Instagram, a square 1:1 will eliminate the need to cut the shot manually, but remember, on Xiaomi 12S Ultra, up to 35% of pixels are lost in this format, compared to 4:3.

In the models with 108 MR sensor (e.g. Redmi Note) 11 Pro+) shoot 4:3 real 12000Γ—9000 pixels, and in 16:9 β€” only 12000Γ—6750. The difference is noticeable when the photo is increased by 200% more.

The best format for video on Xiaomi

For video, the format choice depends on the publishing platform:

  • πŸ“Ί YouTube/VK Video: 16:9 (full-standard HD/4K). Xiaomi. 13T Pro, it's in compliance with the permit. 3840Γ—2160 (4K).
  • πŸ“± TikTok/Instagram Reels: 9:16 (Vertical video. This format is often hidden in the Xiaomi camera menu – you need to enable it through Settings. β†’ Video format β†’ Vertical.
  • πŸŽ₯ Cinematic video: 21:9 (For example, for black stripes, but keep in mind that the POCO X5 Pro in this format video is recorded with permission 3840Γ—1648 β€” It's not real. 21:9, circumcised 16:9.

Critical detail: when shooting at 21:9 on most Xiaomi smartphones, stabilization is disabled (except for flagships with OIS), this is due to the fact that the stabilization algorithms are not optimized for ultra-wide formats.

⚠️ Note: Xiaomi 12 Lite and other models with Mediatek Helio when shooting video in the video 4K 21:9 can appear greenish in dark scenes. This is a processor bug, fixed only in the MIUI 14.0.5+.

Check out the MIUI version (update if necessary)

Turn off HDR (it can amplify artifacts at 21:9)

Use a tripod (stabilization works worse in wide formats)

Hidden format settings on Xiaomi: how to unlock additional options

Some Xiaomi models have undocumented formats available, such as the Xiaomi 11T Pro, which can be activated 18:9 (for older monitors) or 2.35:1 (anamorphic cinematic standard).

  1. Activate Developer Mode (7 times click on the MIUI version in Settings β†’ About Phone).
  2. Turn on USB debugging and connect the phone to the PC.
  3. Use it. ADB-Adb shell settings put global camera_hal3_enabled 1 This will unlock advanced camera settings, including additional formats.

After the reboot, the camera menu will see the option β€œAdditional formats”, but be careful: on Redmi devices with Snapdragon 6xx, these formats can work unstable, causing the processor to overheat during long shooting.

What happens if you reset your camera settings after activating hidden formats?
All non-standard formats will disappear, but they can be returned by re-entering. ADB-However, on certain devices (e.g., commands, POCO M4 Pro) this results in a reset of the colour profile in the factory.

How the format of the frame affects night shooting and HDR

When shooting in the dark or with HDR on, the frame format plays a critical role. In wide formats (16:9, 21:9), Xiaomi algorithms can:

  • πŸŒ™ Increase noise: Due to frame trimming, the sensor uses fewer pixels for exposure.
  • 🎨 Color distortion: at 21:9, white balance can shift to the cold side (especially on the Redmi Note 10 Pro).
  • ⚑ Reduce brightness: in HDR-mode 4:3 grant 0.5-1 EV more dynamic range than 16:9.

Tests on the Xiaomi 13 Pro showed that when shooting nightscapes at 4:3, details in the shadows are 20-30% better than in 16:9. This is due to the fact that the Sony IMX707 sensor in this model is physically optimized for a ratio of 4:3.

πŸ’‘

For night photography, always choose 4:3, which minimizes noise and keeps details in the shadows. At the very least, use 16:9, but turn off HDR if the shot is too dark.

FAQ: Frequent questions about frame formats on Xiaomi

Can I change the format of the video while shooting?
No, all Xiaomi models have a format fixed when recording starts. If you need to switch (for example, from 16:9 to 9:16), you have to stop recording, change the format in the settings and start again. Except for models with HyperOS (for example, Xiaomi 14), where in some modes dynamic aspect ratio change is available.
Why is there no 16:9 or 21:9 formats in Pro mode?
In manual mode (Pro) most Xiaomi smartphones are only available 4:3, which is because RAW processing algorithms (including Leica profiles) are optimized for full sensor use, and cropping a frame at 16:9 or 21:9 will result in data loss, which is contrary to the logic of β€œprofessional” shooting.
Which format is best for document shooting?
For scanning documents, the optimal 4:3 or 1:1 (if the document is square). In these formats, minimal distortion at the edges, and the resolution is enough for text recognition. Avoid 16:9 - it will crop the top/bottom of the page. Xiaomi also has a dedicated Document mode in the camera menu, which automatically selects the format and adjusts the perspective.
Why are there black bands at 21:9 when watching TV?
Black bars appear because most TVs support a maximum of 16:9. The 21:9 format is wider, so the player adds stripes at the top and bottom (letterboxing).To avoid this, either trim the video to 16:9 in the editor, or turn on Just Scan mode in the TV settings (if it supports 21:9).
Can I make a picture of the frames in 1:1 format?
Technically, but it's suboptimal. 1:1 cuts the edges of the frame, so when you take a panorama, you lose some of the overlap between the shots. For panoramas, you'd better use 4:3 and stitch them up in Google Photos or PTGui. Xiaomi also has a built-in Panorama mode that automatically selects the optimal format.
