Creating videos in slow motion has become the standard for modern mobile filming. The slow motion effect allows you to focus on dynamic moments, making the video more dramatic and cinematic. Owners of Android smartphones often look for ways to activate this feature, since it is built into most modern cameras.
Technically, the slow motion process is based on recording more frames per second than usual. If a standard video is recorded at a speed of 30 or 60 frames per second (FPS), then for slow-mo the camera can shoot 120, 240 or even 960 FPS. High frame rate allows you to stretch out the playback time without losing the smoothness of the picture.
In this article we will analyze all available ways to create slow motion video. You'll learn about the system's built-in tools, third-party applications, and post-processing techniques. We will also touch on technical nuances that will help you achieve the best image quality.
Using the built-in camera mode
Most smartphone manufacturers, including Samsung, Xiaomi, Google and Huawei, integrate slow motion mode directly into the standard camera application. This is the simplest and most accessible method that does not require the installation of additional software. The interface may differ, but the operating logic remains the same for all devices.
To activate the mode, you need to open the “Camera” application and find the corresponding item in the menu. It is usually referred to as "Slow Motion" or the abbreviation "Slo-mo". On some models, such as Samsung Galaxy, this mode may be hidden in the additional “More” menu, which must first be activated.
After selecting the mode, the smartphone screen may divide the image into zones Usually a bright bar on the screen indicates the area where the slow motion effect will be applied, and the rest of the video will remain at normal speed. This allows you to create dramatic transitions between normal time and slow motion.
⚠️ Note: When switching to slow motion mode, the camera may automatically reduce the resolution to 720p or HD to ensure high frame rates. Check the quality settings before you start shooting.
To get a stable result, it is recommended to use a tripod or securely hold the phone in your hands. Sudden camera movements in slow-motion video are much more noticeable and can make viewers uncomfortable. There should be a lot of light, since a high shutter speed requires excellent lighting.
Setting video recording parameters
The quality of the final video directly depends on the selected settings. You can often select the frame rate in the camera menu. The standard values are 120 FPS and 240 FPS. The higher this indicator, the more you can slow down the video, but the more light you will need for high-quality shooting.
Some advanced models, for example, the flagships of the series Sony Xperia or Samsung Galaxy Soffer a super slow-mo mode. In this mode, the camera records a very short period of time at 960 FPS. This allows you to see instantaneous events, such as a breaking drop or a popping balloon, in detail.
It is important to monitor focus and exposure. In slow-mo mode, autofocus may be slower due to high CPU load. It is recommended to focus in advance on an object that will move, or use manual focusing if the camera interface allows it.
☑️ Settings before shooting slow motion
It is also worth paying attention to the file saving format. Some phones save slow motion in HEVC (H.265) format by default to save space. This is a modern codec, but older computers or editing apps may not read it without installing additional codecs.
Third-party applications for slow motion
If the built-in camera of your smartphone does not support the desired frame rate or does not have flexible settings, third-party applications will come to the rescue. They allow you to bypass the manufacturer's software restrictions and gain access to the full capabilities of the sensor.
One of the most popular solutions is the application Open Camera. It is free and open source software that gives you complete control over your shooting parameters. Here you can manually set FPS, ISO, shutter speed and white balance.

- 🎬 Footej Camera 2 - an application that supports shooting in RAW and high quality video, often used by enthusiasts.
- 🎥 Slow Mo Camera - a specialized application designed specifically for creating slow-motion effects with the ability selecting an area.
Using third-party software may lead to increased heating of the device. The smartphone processor works at its limit, processing huge streams of data in real time. Therefore, making long high-resolution recordings through third-party applications should be done with caution.
Why may third-party cameras not work on some phones?
Smartphone manufacturers often block third-party applications from accessing the full functionality of the camera via the Android API. This means that the app may not be allowed to enable high frame rate mode or stabilization, even if the phone's hardware supports it. In such cases, only root access or modified versions of system applications help.
Creating a slow-mo effect during editing
It is not necessary to shoot a video immediately in slow motion. Often, better results can be obtained by shooting a regular video at a high frame rate (for example, 60 FPS), and then slowing it down in a video editor. This method gives you more control over timing.
There are many apps for editing on Android. The market leaders are KineMaster, CapCut i VN Video Editor. These apps have a function for changing the speed of a clip (Speed Ramp). You can select a specific section of video and smoothly change its speed.
The main advantage of post-processing is the ability to smoothly slow down only at the right moments. For example, a runner might be running at normal speed, but when he jumps, the video smoothly slows down and then speeds up again. This is called “speed ramping” and looks very professional.
| Application | Processing type | Difficulty | 60/120 FPS support |
|---|---|---|---|
| CapCut | Post-processing | Low | Yes |
| KineMaster | Postprocessing | Medium | Yes |
| Open Camera | Shooting | High | Depends on the phone |
| Standard Camera | Shooting | Low | Yes (automatically) |
When slowing down the video in the editor, it is important that the source material was shot with a reserve of frames. If you shot at 30 FPS and try to slow down the video to 50% speed, the app will be forced to complete intermediate frames (interpolation), which often leads to artifacts and “jerky” images.
Technical requirements and lighting
Shooting in slow motion is an extreme load for the hardware of a smartphone. The camera sensor must read information at enormous speed, and the image processor (ISP) must instantly process this data and write it to memory. This is why many phones do not allow you to shoot slow motion in 4K resolution.
Light is the key factor for success. As the frame rate increases, the exposure time for each frame decreases proportionally. If at 30 frames per second the matrix “sees” light for 1/30 of a second, then at 120 frames it only sees 1/120 of a second. This means that four times more light is needed.
⚠️ Warning: Shooting slow motion in low light will result in digital noise, blurred moving objects and loss of detail. Try to shoot during the day outdoors or in bright studio light.
It is also worth considering the amount of free memory. High frame rate videos take up significantly more space. One minute of recording in 960 FPS mode can weigh several gigabytes. Make sure you have enough free space on your device before you start filming.
Use memory cards with a high speed class (U3 or V30) if your phone supports recording to an external SD card. This will prevent the recording from being interrupted due to a lack of recording speed.
Common problems and their solutions
Users often encounter the fact that video in slow motion plays at normal speed when sent to instant messengers. This is due to the fact that WhatsApp, Telegram and social networks, when compressing videos, often ignore metadata about slowdown and average the frame rate.
To preserve the effect, it is better to first edit the video in an editor, export it as a regular file (where the slowdown is already “sewn” into the frames), and only then send it. Or use the Document function in Telegram to transfer the file without compression.
Another common problem is audio desynchronization. When you slow down too much, the sound also stretches out and becomes low and booming. In professional editing, the sound in such areas is usually removed or replaced with music and sound effects.
⚠️ Attention: Camera interfaces and operating systems are constantly updated. The location of the buttons and menu names may differ from those described in the instructions. Always check the current settings in the “Help” section of your device or on the manufacturer’s official website.
The quality of slow motion depends 90% on the amount of light. The brighter the lighting, the cleaner and smoother the picture will be, regardless of the phone model.
FAQ: Frequently Asked Questions
Why is my slow-mo video so dark?
This is due to the short exposure time of each frame. The camera simply does not have time to “catch” enough light. There is only one solution - add more lighting or shoot only in bright daylight.
Is it possible to make slow-mo from a regular 30 FPS video?
Technically, you can slow it down, but the quality will be low. Jerks will appear because there are not enough frames for smoothness. Modern AI algorithms in editors can smooth this out, but the perfect picture will not come out.
How much space does 1 minute of 960 FPS video take up?
The file size greatly depends on the resolution and codec, but on average, a minute of super slow-motion video on a flagship smartphone can take up from 500 MB to 2 GB of disk space space.
Why is there no sound in slow motion?
When recording at a very high frame rate (usually above 240 FPS), the microphone is often disabled in software, since the audio stream is not synchronized with the video stream. Sound has to be added during editing.
Which phone captures slow-mo better?
Sony smartphones (Xperia series) and Samsung flagships (Galaxy S series) are traditionally considered the leaders. They offer the best stabilization and support for 4K resolution at high frame rates.
