How to cut out parts of a video on Samsung Galaxy: Gallery, Studio and beyond

On a Samsung Galaxy phone, you trim a video in the Gallery app: open the video, tap the pencil Edit icon, tap the scissors and drag the sliders. That removes the start and the end. To cut out a part in the middle, use Samsung’s Studio, which is built into the Gallery, or another editor. If the part you want gone is something you said, a transcript editor removes it by deleting the words.

Menus differ slightly between One UI versions and Galaxy models, as Samsung itself notes (Samsung), so if a button looks different on your phone, look for the same icon.

How to trim a video on Samsung

Samsung’s steps for the Gallery editor (Samsung US, Samsung UK):

1. Open the Gallery app and select the video.
2. Tap the Edit icon (the pencil).
3. Tap the Trim icon (the scissors).
4. Drag the slider bars to set the new start and end.
5. Save.

Samsung lists the video editor for Galaxy S20 models and later. Large or high-resolution videos can take a while to save.

This answers “how to trim a video on Samsung” and “how do I shorten a video on my Samsung phone” when the extra length is at either end. The trim keeps one continuous range. Anything you want to remove from the middle needs one of the methods below.

Cut out the middle with Samsung Studio

Studio is Samsung’s project editor inside the Gallery. It holds several clips in one project, lets you reorder them, and adds text, stickers and a soundtrack. To open it (Samsung US):

1. Open Gallery and tap the menu (three lines) at the bottom.
2. Tap Studio, then Start new project.
3. Select your video and tap Done.

To remove a section in the middle, the dependable method is to keep the two parts you want as separate clips:

1. In the Gallery, trim a copy of the video so it ends just before the unwanted part.
2. Trim another copy so it starts just after it.
3. Start a new Studio project, add both clips in order, and save the movie.

Members of the Samsung Community describe the same trim-two-copies approach for the built-in editor (Samsung Community). It is fine for one cut. For five, it gets tedious.

Auto trim on newer Galaxy phones

Recent Galaxy phones with Galaxy AI have Auto trim in Studio. Samsung describes it as removing pauses or blank parts: it analyses the video and suggests a trimmed version. In a Studio project, tap the scissors icon at the bottom left, preview with Play and tap Apply (Samsung US). Galaxy AI editing tools need a Samsung account and an internet connection and are available on select models running One UI 6.1 or higher.

Auto trim is useful for removing dead air. It decides on its own what counts as blank, though, and it cannot know that the sentence you said twice should go. For that, you need to choose the cut yourself.

Cut out parts with another editor

Any timeline editor on Android can split a clip in the middle: Adobe Premiere’s free mobile app, CapCut, InShot, VN, LumaFusion. The pattern is the same:

1. Import the video.
2. Move the playhead to the start of the part you want to remove and tap Split.
3. Move to its end and split again.
4. Select the piece in between, delete it, export.

Premiere for Android is free for basic editing, needs no account, exports up to 4K and adds no watermark (Tech Advisor). If you just need a clean split, start there. Our CapCut vs InShot page compares two of the most common alternatives.

Remove spoken mistakes by deleting words

For a video of you talking, the parts you want out are usually false starts, repeated sentences and long “ums”. On a timeline you find each one by playing and scrubbing. In a transcript you read it.

slicecut runs on Galaxy phones like any Android phone:

1. Import the clip from the Gallery. The app transcribes the audio; only the audio track is uploaded, to servers in Germany.
2. Tap a word to strike it, or drag across a sentence to strike the line. The cut lands right before the next word.
3. Set every pause in the project to a target length with the pause dial. Pin the pauses that should stay long.
4. Export. The video is rendered on the phone at source quality, without a watermark, and saved to the Gallery.

Unlike Auto trim, nothing is decided for you. You see every word and every pause, and you choose. Nothing is rendered until export, so a struck word comes back with a tap.

Which method to use

What you want to remove	On a Samsung phone

Dead air, quickly	Studio’s Auto trim on supported models
Mistakes and repeats in someone talking	A transcript editor such as slicecut

Tips

• Cut between words, not inside them.
• Leave some pauses in. Talking with no pauses sounds rushed; the typical gap between sentences in talking-head videos is about a third of a second (How long should a pause be?).
• Combining several takes? See how to merge videos on Android.
• On a Pixel or another Android phone, the Google Photos steps are in how to cut a video on Android.
