“I have a bunch of move videos on my iPhone, and I would like to make a home movie and combine all of them, please let me know the easiest way to do it on iPhone.”

When you are creating a home-made movie, you probably end up with several video clips. In such case, you have to merge or combine videos on iPhone. This article will tell you 6 ways to complete the task quickly. Continue reading and follow the easy methods.

Part 1: Considerations for Video Merging

When merging multiple video clips, it’s important to account for differences in format, resolution, and frame rate to ensure smooth playback and consistent output.

1. Resolution and Aspect Ratio

To avoid unwanted black bars or distorted stretching, ensure all clips share the same frame size and ratio before merging. If your source files vary - such as mixing 4K footage with 1080p, you should upscale or downscale them to a unified resolution. Establishing a consistent target resolution ensures that the final output looks uniform and professional across all devices.

2. Frame Rate (FPS)

Consistency in frame rate is vital for smooth motion playback. Combining clips with different fps (e.g., 24fps and 60fps) often results in jittery playback or 'stuttering' as the software attempts to reconcile the different timing. To prevent this, it is highly recommended to unify the frame rate of all clips to match your project settings before the merging process begins.

3. Video Formats and Codecs

Using a variety of file containers (like .MOV or .MP4) and codecs (like H.264 or ProRes) can lead to export errors or hardware playback issues. For the most stable workflow, you should transcode all source material into a single, high-quality intermediate codec. This minimizes the processing load on your computer and ensures that the final merged file is structurally sound and compatible.

4. Audio Sample Rates

Mismatched audio frequencies, such as mixing 44.1kHz and 48kHz audio, can lead to a gradual "drift" where the sound no longer matches the picture. To maintain perfect synchronization, normalize all audio tracks to a standard sample rate (typically 48kHz for video) before merging. This ensures that the audio remains perfectly aligned with the visual cues from start to finish.

Part 2: 5 Fast Ways to Merge Videos on iPhone with Apps

The iPhone Photos app lets you trim a video easily by its simple editing settings. However, can you combine video clips on iPhone without app?

No. The Photos app cannot combine videos together directly. To put teo or multiple videos together on iPhone, you need to turn to the app for help. Follow the 5 apps in this part, and start merging your videos on iPhone directly.

Method 1: Merge Videos on iPhone with iMovie

iMovie is Apple’s built-in video editor designed specifically for iOS devices, offering a clean, intuitive interface for video editing. One of its most commonly used features is the ability to merge multiple videos on an iPhone, allowing you to combine clips into a seamless, polished final project. With just a few clicks, you can join videos into one. It supports common video formats like MP4 (H.264/AAC, HEVC) and MOV (QuickTime), along with older formats like DV/HDV and ProRes. Since it’s completely free, without ads, subscriptions, or in-app purchases, it has become a go-to tool for iPhone users who want to edit videos quickly and professionally. With full compatibility across all modern iOS devices, iMovie provides a convenient way to trim clips, add transitions, apply filters, and more.

1. Run the free video editor from your home screen, tap the Plus icon, and select Movie to make a new project

2. Then you will be taken to your Camera Roll. Touch the video clips to combine on iPhone and tap Create Movie to put the them on the timeline.

3. Adjust the order and set background music. Once tap Done button at the upper right corner, to export iMovie as MP4. You can find the merged video file in the Camera Roll album on iPhone.

We find iMovie incredibly intuitive for quick merging of video and audio with its seamless integration with the Apple ecosystem. However, we often feel limited by its rigid timeline and lack of advanced features like multi-track editing or granular color grading, which can be frustrating when a project requires more creative precision.

Method 2: Combine Videos on iPhone Using Quik

GoPro users often turn to the Quik app when they need a fast and convenient way to combine videos on an iPhone. What many people don’t realize is that Quik isn’t limited to GoPro owners - it’s completely free for all iPhone users and works with any footage stored on the device. With its simple interface and automatic editing tools, Quik makes it easy to merge multiple clips into a single video without needing advanced editing skills. This makes it a practical option for anyone looking to quickly stitch together videos on an iPhone, whether the clips come from a GoPro, the iPhone camera, or any other source.

1. Create a new project in the video editor on iPhone. Tap and expand the All Photos dropdown on the top and select Videos.

2. Choose the video clips that you expect to merge, and tap Add button to open them in the project screen.

3. At the bottom, you can find Effect, Music and Tools for decorate the movie result. After editing, tap Save to save the combined video.

We think Quik is highly efficient for rapid editing, allowed us to join and create polished videos in minutes. However, we were frustrated by the limited manual control over fine details and the occasional stability issues when processing high-resolution files. Overall, it is a good tool for quick social media updates.

Method 3: Edit Videos Together on iPhone via Videoshop

Videoshop stands out from iMovie by offering a more feature-rich editing environment. Among its most practical capabilities is the option to merge multiple video clips into a single file, making it easy to combine footage into a smooth, cohesive video directly on your device. It gives iPhone users access to a wider range of tools, effects, and customization options. While many of its core functions are free, some advanced features and creative elements require in-app purchases. Even so, Videoshop remains a popular choice for users who want more flexibility when editing on an iPhone.

1. Start the video editor app and tap the Plus icon to access your Camera Roll. Select the first video clip to add it to the video editor.

2. You can edit the video clip with the tools on the top and bottom menu bars. Then tap the Plus icon to add other video clips.

3. After editing each video clip, tap the Share icon at the upper right side to open the save your video screen. Choose your favorite destination or tap Save to Camera Roll to export the result.

Videoshop can be called one of the best apps for combining videos on an iPhone. It performs well in maintaining the video quality. However, while the interface is beginner-friendly for quick cuts, we noticed that it can feel a bit cluttered when diving into advanced settings.

Method 4: Merge Videos with Adobe Premiere Clip on iPhone

Adobe Premiere Clip is a lightweight, free video-editing app designed for quick, everyday tasks. As long as your iPhone is running iOS 8.1 or later, you can use it to combine different video clips into one without paying for a subscription or unlocking extra features. Its straightforward interface makes it accessible for any iPhone user who simply want to combine multiple. Whether you’re stitching together travel footage or creating a short montage, Premiere Clip offers an easy way to merge videos directly on your iPhone.

1. Open the free video editor app, and start a new project by tapping the Plus icon. Select On my iPhone and choose the video clips you intend to edit together.

2. Choose Automatic or Freeform mode when prompted. If you want to customize the combination, select the latter. Hold and drag the video clips on the timeline to rearrange them.

3. When it is done, tap the Share icon and select Save to Camera Roll or upload it to Dropbox, YouTube and more.

Note: If the merged video is too large, you need to compress videos on iPhone to fit the upload requirements of different platforms.

We found that while the app's clean interface makes it incredibly simple to quickly join clips into a 'social-ready' movie, the 'Automatic' mode often cuts footage too aggressively, leaving us with a sequence that feels disjointed. In addition, the lack of advanced transition options can be a problem for more detailed work.

Method 5: Use VivaVideo to Merge Videos on iPhone

VivaVideo is a versatile video-editing platform available across multiple operating systems, and its iOS version brings many of its popular features to iPhone and iPad users running iOS 9.0 or later. You can use it to merge videos into one with ease, giving you a straightforward way to combine footage into a smooth, continuous sequence. It also provides many transitions and templates for you to enhance video visual effects.

2. Modify each clip until you are satisfied, and enter the video save screen.

3. Choose your favorite resolution and save it to your Camera Roll or share it to social networks.

We found that VivaVideo offers a highly intuitive, 'one-tap' merging experience on iPhone, making it easy to stitch clips together with stylish transitions and trendy templates. However, we also encounter lag or sudden crashes when processing longer projects. The app can be installed from the App Store at no cost, though certain advanced tools and effects are only available in the premium version.

Part 3: Tips for Merging Videos on iPhone

Tip 1. Standardize Orientation

Merging vertical and horizontal clips usually results in unsightly black bars. To ensure a consistent full-screen look, use the Rotate or Crop tools to unify the orientation of all clips before you hit merge.

Tip 2. Quality and Sync Maintenance

Mismatched frame rates can cause stuttering playback or audio drift. For the smoothest results, unify your clips to a consistent resolution and frame rate to keep the visuals sharp and the audio perfectly in sync.

Tip 3. Smart Compression

Merged files often balloon in size because they export in uncompressed or high-resolution formats. Use a compression tool after merging to reduce the file size for easier sharing while maintaining the best possible visual balance.
