How to slow down video on Xiaomi phone: full instructions

Xiaomi’s current smartphones, powered by MIUI shells or the new HyperOS, are powerful multimedia centers capable of processing high-resolution video content. Often users are faced with the need to change the speed of the video playback, whether it’s a training video where the speaker talks too fast or a workout recording that requires detailed analysis of movements. Standard tools provide flexible tools for managing timeline, but they are not always obvious to the beginner.

In this article, we will take a closer look at all the ways you can slow down video streams, the built-in functionality of the gallery, the capabilities of popular video players, and the specialized camera settings to create a slow-mo effect, and understanding these nuances will allow you to fully control the media content on your device.

Whether you’re using the Redmi budget model or Xiaomi’s flagship, the way you work with media files is the same, but it’s worth considering that CPU performance can affect the smoothness of playing highly compressed video files in slow motion.

Use of built-in video player in the Gallery

The standard Gallery app in Xiaomi smartphones is equipped with a fairly advanced video player, which is often ignored by users in favor of third-party solutions. To take advantage of its features, you need to open the desired video file and click on the screen to appear control menu. In the lower right corner or in the menu “More” (three dots) hides the button for settings speed.

Once you activate the speed menu, you'll see a slider or set of presets that can change the playback tempo, and you can both speed up content for quick viewing, and slow it down for detailed study, and it's important to note that the built-in player is optimized for the codecs used by the phone's camera, so playback will be as smooth as possible.

However, it is worth remembering the technical limitations: if the video has high resolution (for example, 4K) and high bitrate, software slowdown can cause slowdowns on devices in the mid-range segment, this is due to the fact that the processor has to decode the frames with double or triple frequency.

• 📱 Open the video in the Gallery app and tap the screen.
• ⚙️ Click on the “More” icon (three dots) or find the speed icon (often looking like a speedometer).
• 🐌 Choose a value less 1.0x (for example, 0.5x or 0.75x) slow down.
• ▶️ Enjoy browsing at a modified pace using a slider for fine-tuning.

⚠️ Note: In some versions of the shell MIUI The speed change function can be hidden in the Player Settings menu, which is only available when the screen is horizontal. Be sure to turn the device to fully access the functions.

If the standard interface doesn’t offer the right options, your firmware version may have region limitations, and then consider alternative methods described below that work more consistently on custom builds.

Configure third-party video players (VLC, MX Player)

When the standard gallery isn’t enough, Google Play’s specialized apps come to the rescue, with VLC for Android and MX Player being the leaders in the niche, and these apps have their own decoders, allowing them to handle heavy files where the system player can choke.

In VLC, speed control is implemented through an equalizer or a separate menu. When playing a video, click on the speaker icon or three dots in the corner, then select Speed. Here you can not only select preset values, but also manually set an exact ratio, for example, 0.65x. This is especially useful for learning foreign languages or dance bundles.

The MX Player offers an even more flexible interface. In playback mode, call the control menu and find the "Playback Speed" option. A unique feature of this player is the ability to adjust the speed separately for audio and video, although for most tasks synchronous change is enough. Also available is the "Playback" function, which, combined with slowing down, provides a powerful tool for analysis.

Using third-party software has its advantages: these applications are often updated and receive support for new compression formats faster than Xiaomi system components, and they allow you to save speed settings for specific files or types of content.

Creating slow-motion video through the camera (Slo-mo)

If your goal is not just to watch, but to create new content with a slowing effect, you will need a Slo-mo mode in the Camera app.This mode records high-frequency video (usually 120 or 240 frames per second), and then programmatically stretches the time, creating a smooth and cinematic effect.

To activate, open the Camera app, go to More and select Slo-mo. It is important to provide excellent lighting before shooting, because at a high frame rate, the matrix captures less light per individual frame. Lack of light will lead to digital noise and lubrication of movement.

After you shoot, you can edit the slowdown area. Open the video in the gallery, click "Edit" and find a timeline that shows normal play zones and deceleration zones, and you can move the boundaries of those zones, choosing which moment to slow down and which to lose in real time.

• 🎥 Launch the Camera app and go to “More” mode» → «Slo-mo».
• 💡 Make sure the scene is well lit (daylight or studio lighting).
• 📹 Press the recording button and perform the action you want to capture.
• ✂️ In the gallery, edit the beginning and end of the slowdown effect on the timeline.

Files shot in Slo-mo take up significantly more space in the device’s memory, a minute of this video can weigh as much as 5 minutes of normal recording, and it is recommended to regularly clean the memory or transfer such files to the cloud.

⚠️ Not all Xiaomi models support 240 entry FPS. Budget devices may limit resolution when slowed down to 720p, while the flagships write in 1080p or 4K.

Speed Editing in Video Editor Applications

For more complex processing, such as creating a smooth transition between normal and slow speed ramping, built-in tools may not be enough, and mobile video editors like CapCut, InShot or KineMaster come to the rescue, enabling you to work at speed at the professional editing level.

In CapCut, you just import the video, select the desired snippet on the timeline, and select the Speed tool. Here you can use Curves, which allows you to create (castom) graphs of speed change, so that the video slows down smoothly at the climax and returns to normal tempo just as smoothly.

When exporting such a video, it's important to get the right parameters. If you slow down a video that was originally shot at 30 FPS, the program will have to generate intermediate frames (interpolation), which can lead to artifacts, so to slow down the editor qualitatively, it's better to shoot the source material in 60 FPS.

Using professional editors opens up access to the optical motion compensation function, which artificially creates missing frames at a strong deceleration, making the picture incredibly smooth even at a normal 30 frames per second.

Problems with desynchronization of audio and video

One of the common problems with slowing down video on Xiaomi smartphones is the desynchronization of sound and image. When video stream slows down programmatically, the audio track also needs to be stretched. If the processing algorithms fail, the sound can start to stutter or lag behind the speaker's lips.

Built-in players usually do this well using key-saving algorithms. However, third-party applications may experience codec conflicts. If you notice that when you slow down, the sound has become similar to the voice of a robot or disappeared altogether, try changing the audio output in the player settings.

Converting video to a format with more standard parameters (e.g. H.264 instead of H.265/HEVC) can solve the compatibility problem, and it’s worth checking whether power saving mode is on, which can limit the processor resources needed to process real-time audio.

• 🔊 Check the audio output settings in the player app (e.g. switching to AudioTrack).
• 🔄 Try converting the video into a format MP4 (H.264) slow down.
• 🔋 Turn off the “Energy Saving” mode while viewing heavy files.
• 🎧 Use wired headphones for diagnosis: sometimes Bluetooth codecs add extra latency.

⚠️ Note: When slowing down the video below 0.5x The original audio track is often unreadable, and in professional editors, in such cases, the sound is completely turned off or replaced with a musical accompaniment.

Effects of deceleration on battery charge and heating

The process of decoding and re-rendering video in slow motion requires active computing resources. The graphics processor (GPU) and video core work with increased load, which inevitably leads to increased power consumption and heating of the smartphone case.

This is especially noticeable when watching high-resolution (4K) video through third-party players with image enhancements enabled. The device can significantly heat up at the top of the case where the processor is located. In summer or when using cases with poor heat transfer, this can lead to trotting (decreased performance) and video jerks.

To minimize heat, it is recommended to reduce the brightness of the screen and close the background applications. If you plan to watch slow-motion videos for long periods, for example, to analyze sports equipment, it is better to connect the device to the power source, but monitor the temperature.

💡

Use Game Turbo even for video players. Add the player app to the list of games in the Security app, which will prevent the system from limiting processor performance and shutting down the network, which will ensure stable playback without jerking.

Understanding your Xiaomi’s thermal limitations will help avoid sudden screen shutdowns or lags at the most important point of view.Flagship models handle load better thanks to more advanced cooling systems.

💡

Slowing down video is a resource-intensive operation. For stable performance in 4K and slowing down above x2, it is desirable to have a smartphone with a Snapdragon 7-series processor or higher and a minimum of 6 GB of RAM.
