Samsung S25 AI Video Editor: Features, How to Use, and More

Samsung’s Galaxy AI promises to automate highlight reels on the Galaxy S25, but the toolset is split between what ships at launch and what arrives later. This guide walks through Auto Trim, the free period, and how to navigate the Gallery app’s Studio editor.

Auto Trim feature: Creates instant highlight reels from videos on Galaxy S25 · Object Eraser for videos: Expected with One UI 7.1 update (2025) · Galaxy AI availability: Free on Galaxy S25 series until end of 2025 · S25 series launch: January 2025

The table below distills the six key specs you need to know about the S25’s AI video editing capabilities, from software version to free access duration.

Does the Samsung Galaxy S25 have an AI video editor?

Yes—the Galaxy S25 series ships with a dedicated AI video editor built into the Gallery app. Samsung calls the new workflow “Studio,” and it’s designed to automate the parts of video editing that most people skip because they take too long.

What is Galaxy AI?

Galaxy AI is Samsung’s umbrella brand for on-device machine learning features across the S25 series. For video, it powers Auto Trim, which Samsung UK describes as AI that “extracts key scenes to create instant, auto-generated videos and reduce editing time.” The same AI pipeline handles photo editing, text summarization, and real-time translation.

Which S25 models support the AI video editor?

The AI video editor works on all three S25 models: the base S25, S25+, and S25 Ultra. According to Samsung US Support, the feature is part of One UI 7.0 out of the box and does not require a separate download.

The pattern: Samsung is pushing AI editing to the entire S25 line, not reserving it for the Ultra. The trade-off is that more advanced tools like Object Eraser for video are still in development, meaning early adopters get Auto Trim now but will have to wait for the full suite.

Does the Samsung Galaxy S25 have AI features?

Beyond video editing, the Galaxy S25 packs a wide AI arsenal. Auto Trim sits alongside Audio Eraser, Circle to Search, AI Select, and ProScaler, as listed in Samsung’s UK buying guide.

List of AI features on Galaxy S25

• Auto Trim (video highlight reel)
• Audio Eraser (remove background noise from video audio)
• Object Eraser (photo, video version expected later)
• Circle to Search (Google integration)
• AI Select (context-aware actions)
• ProScaler (upscaling in games and apps)

How AI enhances video editing

Samsung US Support explains that Auto Trim “removes unnecessary parts such as pauses or blanks.” The AI analyzes each clip’s motion, speech, and pacing to keep only the engaging moments. You can then adjust the length with a custom slider or let the AI choose a short or long reel format.

“Auto Trim analyzes selected footage and automatically generates a short or long reel with key scenes.”

The implication: Samsung is aiming to make video editing as easy as taking a photo. The AI handles pacing judgment, which traditionally requires experience. For casual creators, that means a finished clip in under a minute. For power users, the manual editor remains fully accessible.

Does the Samsung S25 have an AI photo editor?

Yes, the S25 includes an AI photo editor for object removal and background edits. The video editor follows a similar design philosophy but focuses on temporal editing—trimming, merging, and applying effects.

Difference between AI photo and video editor

The photo editor uses generative fill to remove objects and adjust backgrounds. The video editor, by contrast, works on the timeline: it cuts, reorders, and applies filters. Samsung Canada Support documents the manual tools (Trim, Transform, Flip, Decorations, Filter, Audio), while the AI layer adds Auto Trim and the upcoming Object Eraser for video.

Photo editing tools available

Photo AI tools include Object Eraser, Shadow Eraser, Reflection Eraser, and background generation. These are separate from the video editor but share the same Galaxy AI infrastructure.

What this means: If you need to edit a photo, the AI tools are mature and available now. Video AI is catching up—Auto Trim is strong, but video object removal is still months away.

How to edit videos in Samsung S25

Editing a video on the S25 breaks into two paths: the AI automated route (Auto Trim) and the manual route (Studio Video Editor). Both start in the Gallery app.

Using Auto Trim to create highlight reels

1. Open the Gallery app.
2. Tap Menu (three lines or dots at the bottom) and select Go to Studio. (Samsung YouTube guide)
3. Tap Start a new project.
4. Select one or more videos. Or tap Search > Shot types > Video to filter clips. (Samsung US Support)
5. Tap the Auto Trim icon (located at the bottom left of the editing screen).
6. Choose a reel length: Short or Long, or drag the Custom length slider.
7. Preview the result by tapping Play. If happy, tap Apply.
8. Add Text, Stickers, Draw, or Audio if desired.
9. Tap Save movie to export. (Samsung US Support)

Manual editing with Samsung Video Editor

For full manual control, open Gallery, select a video, and tap Edit. The classic editor offers Trim, Transform, Flip, Decorations, Filter, and Audio tools, as documented by Samsung Canada Support. You can reorder clips by touching and holding, then dragging—a workflow identical to the older Galaxy models.

Applying AI effects and filters

After Auto Trim, you can apply AI-driven effects: Background blur, Portrait video, and Auto color grading. These are one-tap enhancements that adjust lighting, skin tones, and depth. They work on the trimmed reel just as they do on manual edits.

“Users can reorder clips by touching and holding a clip, then dragging and dropping it.”

How do I activate Samsung AI and is it free?

Galaxy AI is active by default on the S25 series. There is no separate toggle to enable the video editor—it appears in Gallery automatically. But you may want to check your AI settings and understand the pricing.

Activating Galaxy AI on S25

Open Settings > Advanced features > Galaxy AI to see the full suite. You’ll need to sign in to a Samsung account on first use. No payment method is required during the free period.

Samsung AI pricing and free period

As of the S25 launch, Samsung UK states that Galaxy AI is “free until end of 2025.” This applies to all supported Galaxy devices, including the S25 series. Samsung has not announced any paid plans beyond that date.

Future plans for Galaxy AI access

It remains unclear whether Samsung will charge a subscription or introduce a tiered model. TechNewsTT suggests that the company is evaluating options, but nothing is confirmed. Users who buy an S25 in 2025 get at least one year of free access.

“Samsung’s AI video analytics speeds photo search and video editing.”

TechNewsTT – Third-party analysis

The catch: The free period gives Samsung time to prove the value of AI editing. If users rely on Auto Trim daily, a paid tier would be an easy upsell. Until then, you can use all features without worrying about cost. Samsung must decide whether to monetize as a subscription or bundle it into future phone prices.

For anyone buying an S25 in 2025, the choice is straightforward: use the AI video editor freely for the first year, and keep an eye on Samsung’s announcements for 2026. If you need Object Eraser for videos, you’ll have to wait—but Auto Trim is ready and remarkably effective right now.
