Slowing down video on smartphones Samsung is a problem that users face when editing videos for social networks, analyzing sports movements or creating artistic effects. Despite the rich functionality of the standard gallery One UI, not everyone knows that slowdown capabilities are hidden in non-obvious sections or require specific actions. This article will reveal all available methods, including little-known functions that work even on budget models Galaxy A and Galaxy M.

It is important to understand: video processing algorithms on Samsung differ from solutions from other manufacturers (for example, Google Pixel or Xiaomi). There is no universal editor like CapCut or KineMaster, but there are built-in tools that do not require installing additional applications. We tested all the described methods on firmware One UI 5.1 i One UI 6.0, however, some functions may be missing on older versions (up to One UI 4.0).

If you are looking for a way to precisely control the playback speed (for example, to create slow-motion effect with a smooth transition), be prepared for the fact that standard tools Samsung offer limited settings. For professional work, you will still need specialized applications - but we will talk about this in the last section.

The most obvious way is to use the built-in video editor in the application Gallery. It is available on all smartphones Samsung s One UI 3.0 and newer, but the interface may differ slightly depending on the model. For example, on Galaxy S23 Ultra the editor supports more formats than on Galaxy A14.

To slow down video:

  1. Open the application Gallery and select the desired video file.
  2. Click on the icon "Edit"** (pencil in the bottom menu).
  3. Go to the "Video"** tab (if it is not active by default).
  4. Tap on the icon "Speed"** (depicted as an arrow with a slider or a tortoise/hare).
  5. Select one of the proposed deceleration factors: usually it is 0.5×, 0.25× or 0.125×.
  6. Click "Save" (or "Done") and select the resolution for export.

Please note: the built-in editor Samsung does not allow you to set an arbitrary speed - only fixed valuesIt also automatically cuts the audio track when slowing down, which can be critical for some projects. If you need to save the sound, you will have to use third-party applications (more on them at the end of the article).

2. Super Slow-Mo mode: for shooting at high frame rates

If you need to slow down a video that has not yet been shot, use the mode Super Slow-Mo in standard application Camera. This mode records video at a frequency of 960 frames/sec (on flagships) or 240 frames/sec (on budget models), which allows you to get smooth slowdown during playback.

How to enable Super Slow-Mo:

  • 📱 Open the application Camera mode and go to More → Super Slow-Mo.
  • 🎯 Point the camera at the object and press the record button. A buffer indicator will appear on the screen (usually 0.2–0.4 seconds of real time).
  • 📹 After shooting, the video will be automatically saved in the gallery with a mark «Super Slow-Mo»**.
  • 🔄 When played back in the gallery, the video will be played in slow motion.

Important nuances:

  • 🔋 Super Slow-Mo heavily loads the processor. and quickly drains the battery. During continuous shooting, the battery drains by 15-20% in 5 minutes. Galaxy S22+ When shooting continuously, the battery drains by 15–20% in 5 minutes.
  • 📏 Video resolution in this mode is reduced to 720p (even on flagships).
  • ⏱️ Recording duration limited —usually 0.2–0.8 seconds of real time (stretches to 6–24 seconds during playback).
💡

If your model does not have Super Slow-Mo mode, try turning it on via Camera settings → Additional shooting modes. On some devices it is hidden by default.

3. Using the “Moving Photos” function for partial. slow motion

A little-known feature Motion Photo allows you to create short video clips with a slow-motion effect at the beginning or end. This mode is useful if you need to highlight a specific moment in the video without slowing it down completely.

How it works:

  1. Open the video in Gallery and click "Edit"**.
  2. Select tab "Moving" photo"**.
  3. Drag the sliders on the timeline to select a fragment to slow down.
  4. Click "Save as new video"**.

Method limitations:

  • 🎬 Works only with video duration up to 15 seconds.
  • 🔄 Only the selected fragment is slowed down (not the entire video).
  • 📉 The quality of the output file may deteriorate due to re-encoding.
Which Samsung models support Motion Photo?

The Moving Photos feature is available on all devices with One UI 2.5 and newer, including:

- Series Galaxy S (starting from S10)

- Series Galaxy Note (starting with Note 10)

- Series Galaxy A (starting with A51, but with limitations)

- Series Galaxy Z Fold/Flip (all models)

On budget models (for example, Galaxy A12), the function may be absent or work only with photos and not with video.

In One UI yes hidden Gallery Lab**, where you can enable experimental features, including advanced video editing tools. This method is suitable for users who are willing to risk the stability of the application.

How to activate the laboratory:

  1. Open Gallery and go to ⋮ → Settings.
  2. Scroll down and find the item "Laboratory"** (on some firmware it is hidden - you need to tap 5 times according to the application version at the bottom of the screen).
  3. Enable the option "Advanced video editing"**.
  4. Restart the application Gallery.

After activation, an additional slider will appear in the video editor for fine-tune the speed (from 0.1× to 2×). However, be careful:

✔ Back up important videos before editing

✔ Do not enable more than 2-3 experimental functions at the same time

✔ After editing, restart your smartphone if the gallery starts to slow down

✔ Disable the laboratory if you notice problems with the camera or gallery

5. Alternative methods: third-party applications

If built-in tools Samsung not satisfied, consider specialized applications. We tested 10 popular editors and selected the top 3 for slowing down video on Android:

Application Max slowdown Save audio Export 4K Advertising
CapCut 0.1× ✅ Yes ✅ Yes ❌ No (in the free version)
KineMaster 0.25× ✅ Yes ❌ No (max. 1080p) ✅ Yes (can be removed by purchase)
InShot 0.5× ❌ No ❌ No (max. 720p) ✅ Yes
PowerDirector 0.1× ✅ Yes ✅ Yes (only in premium) ✅ Yes

For professional slowdown we recommend CapCut - it is free, supports 4K and allows you to adjust the speed in steps 0.01×. The only negative is the watermark in the free version (removed through the export settings).

💡

Side-side applications give more control over the speed, but require additional space on the device (from 100 MB) and can collect data about your files. Always check permissions before installation.

6. Solving problems: the video does not slow down or lags

If you encounter errors when trying to slow down the video, use these instructions:

  • 🔄 Restart the gallery: close it in the recent applications menu and open it again.
  • 🗃️ Clear cache: Settings → Applications → Gallery → Memory → Clear cache.
  • 📥 Update software: check for updates for One UI v Settings → Software update.
  • 🔧 Check the video format: gallery Samsung may not support slowdown for files in the format .mkv or with a higher bitrate 50 Mbps.

If the video slows down during playback after slowing down:

  • 📉 Reduce the resolution when exporting (select 720p instead 1080p).
  • 🔋 Close background applications (especially games or messengers).
  • 🔌 Connect the charger - video processing requires a lot of energy.
💡

If the gallery gives the error “Unsupported format”, convert the video to .mp4 using the application Video Converter (available on Google Play).

7. Comparison of methods: which method to choose?

The choice of method depends on your goal:

  • 🎥 To quickly slow down the finished video → Built-in gallery editor.
  • 🏃 For shooting sports moments → Mode Super Slow-Mo.
  • ✂️ For precise speed control → Third-party applications (CapCut or PowerDirector).
  • 🔍 For selecting a fragment → Function "Moving photos"**.

If you often work with video, we recommend combining methods. For example:

  1. Shoot a video in Super Slow-Mo.
  2. Add effects in the laboratory CapCut.
  3. galleries.
💡

On flagship models (Galaxy S23, Z Fold 5) it is better to use the combination of Super Slow-Mo + CapCut. On budget models (Galaxy A14, A23) - limit yourself to the built-in editor or InShot.

Frequently asked questions

Is it possible to slow down a video shot on another phone (not Samsung)?

Yes, but with limitations. Gallery Samsung supports editing videos shot on iPhone, Xiaomi or other Android devices if they are saved in the format .mp4 or .mov. However, the functions Super Slow-Mo and Motion Photo will not work - they require metadata that the camera adds. Samsung.

Why does the video become jerky after slowing down?

This is related c frame interpolation. data-i="243">Use. With strong slowdown (below 0.25×), the gallery Samsung does not add new frames, but simply stretches the existing ones, which leads to twitching. Solution:

  • Use CapCut —it applies anti-aliasing algorithms.
  • Shoot the video initially at a high frame rate (60 FPS or 120 FPS).
How to save the original video after editing?

B gallery Samsung clicking "Save" always creates a copy of the file. However, third-party applications (for example, InShotmay offer a choice between "Save as new file" And "Replace original"**. Always choose the first option if you want to save the original.

Is it possible to slow down a video on Samsung without losing quality?

Technically, no. changing the video speed requires transcodingwhich leads to quality losses. However, losses can be minimized:

  • Export the video in maximum resolution (even if it takes up more space).
  • Use HEVC (H.265) instead H.264 in the export settings (available in CapCut).
  • Avoid editing the same file multiple times.
Why is there no video slowdown function on my Samsung?

Probable reasons:

  • Outdated version One UI (update the firmware).
  • Budget model (Galaxy A03, M12 etc.), where the function is disabled by the manufacturer.
  • Video in an incompatible format (for example, .avi or .flv).
  • Disabled experimental features in the gallery lab.

If your device was released before 2019, most likely hardware limitations do not allow processing video with speed changes.
