Samsung’s One UI ecosystem has evolved into a sophisticated mobile workstation, leveraging hardware acceleration and machine learning to streamline video post-production. For users looking to combine or merge videos on a Samsung phone, the process no longer requires heavy desktop software. By utilizing the native Gallery app and the integrated Samsung Studio, you can achieve professional-grade results with minimal manual input.

Method 1: Using the Native Gallery Editor (Quick Merge)

For a rapid stitch of multiple clips, the native Gallery application utilizes a streamlined interface optimized for speed. This method is best for automation-focused workflows where time-to-output is the primary metric.
1. Open the Gallery app and navigate to the folder containing your footage.
2. Long-press on the first video to enter selection mode, then tap the additional videos in the order you want them to appear.
3. Tap the Create button (often represented by a "+" or found in the "More" menu) and select Movie or Video.
4. The editor will automatically place the clips on a timeline. Here, you can drag and drop clips to reorder them.
5. Tap Save to render the merged file. Samsung’s AI-driven encoder will optimize the bitrate to ensure the final output retains high-fidelity resolution while managing file size.
Method 2: Leveraging Samsung Studio (Advanced Automation)

With the introduction of One UI 6.0 and higher, Samsung introduced Samsung Studio, a project-based editor that allows for more complex layering and AI-assisted transitions.
1. Access Samsung Studio via the App Drawer or the Gallery "Drawer" menu.
2. Start a new project and import your video assets. Studio allows for multi-track editing, which is essential for complex merging involving overlays.
3. Use the "Auto-align" feature if available, which uses AI to sync audio peaks between clips—perfect for multi-cam setups.
4. To enhance the merge, tap between two clips to add AI-generated transitions. These transitions analyze the edge frames of both videos to create a seamless visual flow.
5. Export your project. You can choose between H.264 or HEVC (H.265) formats for maximum efficiency in storage and sharing.
AI Implementation Score: Video Merging on Samsung
To help you decide which tool fits your workflow, we have analyzed the efficiency of Samsung’s internal tools based on our Smart AI Fix benchmarks.
| Metric | Gallery Editor | Samsung Studio | Third-Party AI Tools |
|---|---|---|---|
| Processing Speed | High | Medium | Variable |
| AI Scene Detection | Basic | Advanced | High |
| Automation Level | 8/10 | 7/10 | 9/10 |
| Final Render Quality | Lossless | Optimized | Compressed |
Pro Tip: AI Frame Interpolation

When merging videos with different frame rates (e.g., 30fps and 60fps), Samsung’s neural processing unit (NPU) works in the background to interpolate frames. To ensure the smoothest playback, always set your export settings to match the highest frame rate of your source clips. This prevents "jitter" and ensures the AI-driven motion smoothing can operate effectively across the merged timeline.
By mastering these native tools, you eliminate the need for data-heavy third-party applications, keeping your metadata secure and your hardware running at peak efficiency.
