How to make slow-motion video on Xiaomi Redmi 8 Pro

Creating cinematic videos in slow-motion format has become available to every owner of a modern smartphone, and the Xiaomi Redmi 8 Pro is no exception. The built-in image processing software algorithm allows you to capture moments that the human eye usually does not have time to notice in real time, opening new horizons for creative shooting of sports moments, falling objects or just beautiful landscape details.

However, despite the apparent simplicity of the MIUI interface, many users have difficulty finding the right settings or do not understand why the final video does not look like it does in commercials. Features and resolution play a key role here. In this article, we will discuss the entire setup process in detail so that you can get the most out of the camera capabilities of your device.

It is important to understand that the quality of the final file depends on the lighting and stability of the hands. Redmi 8 Pro is equipped with optical stabilization, but software interpolation of frames requires certain conditions for correct operation. We will consider not only the standard mode, but also hidden nuances that will help to avoid blurring and artifacts.

Preparing the camera for shooting in high resolution

Before you go directly to slow motion, you need to make sure that the basic camera settings are set correctly. Often users ignore the pre-cleaning of the lens or the aspect ratio settings, which ultimately affects the image quality.

Go to the camera settings via the gear in the upper right corner of the interface. It's worth checking the default video resolution here. Although slow-motion mode has its own settings, the general system settings affect color processing and dynamic range. Make sure that the HDR option for video is enabled if it's available in your firmware version.

Always wipe the camera lens before shooting slow-motion video, as when slowed down, even small scratches or dust become very noticeable on the final video.

There is a common misconception that slow-motion requires manual switching, and in fact, Xiaomi's automatic algorithms often do better, especially in good lighting, and the key is to give the system a couple of seconds to focus before it starts.

Search and activate Slow Motion

The camera interface in the MIUI shell may vary depending on the Android version and regional firmware, but the logic remains the same. On the main screen of the shooting, you need to find a menu of additional modes, usually indicated by the words "More" or an arrow down in the bottom dashboard.

In the list that opens, look for an icon that says "Slow motion" or "Slow motion." If you don't see it on the first screen, scroll through the list of modes left or right. In some versions of MIUI, this mode can be hidden in the "Profi" subsection or require you to download additional components on the first run.

  • πŸ“Ή Open the Camera app on the home screen.
  • πŸ“‚ Click on the "More" menu at the bottom of the screen.
  • ⏱ Select the "Slow Motion" option).
  • βš™οΈ Click on three points or a gear inside the mode to adjust the frame rate.

When you select a mode, look at the top of the screen, and it should show you what you're doing, like 120 or 240 frames per second, and it's the numbers that determine how smooth and slow your video is going to be, and the higher the value, the slower the slowdown, but the lower the resolution.

Frequency setting and permissions

The key to creating a quality slow-motion is the right frame rate. Redmi 8 Pro supports recording at different speeds, and each mode has its own resolution limitations. 120 fps (frames per second) is considered standard, which gives a fourfold slowdown when played on the screen 30 fps.

For a more dramatic effect, you can choose 240 fps, in which case each second of real time is stretched by 8 seconds of video, but it is worth remembering that as you increase the speed of shooting, the sensitivity of the matrix decreases, which means that 240 fps requires significantly more light than 120 fps.

Resolution is also a compromise. Often when choosing the maximum frame rate, the system automatically reduces the resolution to HD (720p). If you want detail over super slowing, you better choose 120 fps in Full HD. This will provide a clearer picture without losing smoothness.

Photography techniques and work with light

Slow-motion video relentlessly reveals lighting flaws. What looks normal in a normal shoot can turn into a noisy and dark spot in slow-motion. Basic principle: the faster the recording speed, the brighter the lights should be. Try to shoot in the afternoon outdoors or in well-lit areas.

Camera stabilization is critical. Even microscopic hand shaking as time slows down turns into a violent shaking of the frame. Use both hands to hold your smartphone, press your elbows against your body, or encircle the device against a stationary object. Ideally use a tripod, especially if you're shooting a static object in motion.

⚠️ Attention: When shooting under artificial light (lamps, chandeliers) at high speed, there may be flickering or stripes on the screen. This is due to the frequency of alternating current on the network. Try to use natural light or adjust the flicker frequency in the camera settings.

Focusing is another important aspect: the camera must "understand" what to focus on before the action begins. Press the screen at the point where the main movement will occur to capture focus and exposure, which will prevent the focus from "breathing" and the brightness jumping at the most critical moment.

Comparison of time-lapse modes

To better understand the difference between the available settings, let’s look at their specifications in a comparative table, which will help you quickly navigate which mode to choose for a particular scene.

As you can see from the table, the 240 FPS mode requires you to sacrifice resolution and light for maximum smoothness. 120 FPS mode is the β€œgolden mean” for most use cases of the Xiaomi Redmi 8 Pro. Standard video does not give a slowdown effect, but allows you to use the full potential of the sensor.

Why 240 FPS video may look less clear
At 240 frames per second, the array reads information at a very high speed, which causes each individual frame to receive less light, which leads to the need for software-based brightness (ISO), which increases digital noise and reduces overall picture detail.

Editing and saving slow-motion videos

Once the video is recorded, it automatically stores it in the gallery, but it often happens that the slowdown is applied to the entire video, not to the key point. The built-in MIUI editor allows you to adjust the deceleration points. Open the video in the gallery and click "Change".

You'll see a graph on the timeline that shows the playback speed, and you can move the sliders to determine which part of the video is going to play at slow motion and which is going to play at normal speed, and that creates a professional acceleration and deceleration effect in one clip.

Remember, processing these videos requires processor resources. If the phone gets hot or slow after shooting, let it cool before editing or exporting. Keep the final files in their original quality so you don't lose the parts when you recompress.

⚠️ Attention: The slow-motion video format may not be supported by some older TV models or PC video players.If the video is not played, convert it to standard. MP4 using a video converter, but this can remove the effect of variable deceleration.

Frequently Asked Questions (FAQ)

Why is slowing down video going dark?
This is because of the short shutter speed of each frame, and at a high frame rate (120/240 FPS), the array doesn't have time to capture enough light, so you can only shoot in bright daylight or use additional light sources.
Can I shoot slow-motion in 4K on the Redmi 8 Pro?
Unfortunately, the technical specifications of the Redmi 8 Pro processor and sensor do not allow you to combine 4K resolution and high frame rate. The maximum that the device is capable of in this mode is Full HD at 120 frames or HD at 240 frames.
Where are the slow motion files stored?
All videos are saved in the standard Gallery folder. In the file manager, the path usually looks like Internal Storage/DCIM/Camera. Files have a standard.mp4 extension, but can weigh more than regular videos of the same duration.
Why is the sound in slow-motion video distorted or absent?
When the audio track slows down, it also stretches to become a low-frequency hum. Many smartphones automatically turn off 240 FPS audio recording or heavily filter it to avoid discomfort. For 120 FPS, the sound is usually stored, but can be muted.

The quality of slow-motion video is 90 percent dependent on the amount of light in the scene, and without good lighting, even the most powerful processor can't produce a clear picture.
