So you have several video clips waiting to be combined into a single file, is there a simple utility to stitch together all the clips? At fast speed and original quality? If you are bothered by articles recommending complex editing software, you have come to the right place.

Before we walk you through the easy solutions to merge videos together on Windows 10, macOS and iPhone, there are several aspects worth noting:

  • The source video clips might have different aspect ratio and resolutions;
  • Your videos come from different resources and are varied in formats, such as MP4, MOV, VOB, MTS, ISO…

No matter you have clips from iPhone, DSLR, GoPro, DJI, DVDs, ISO files, a series of MTS, ripped chapters, this guide will help you to combine videos into one without quality loss.

VideoProc can also cut out your unwanted slices of a clip and merge the remaining segments into one video so that you can get your favorite parts of any footages joined. This is very helpful when you wish to remove a few seconds or minutes of dead time at the beginning of your video, or unpleasant phones/drones/GoPro camera droop at the end. Or you just want to get a shorter video with smaller file size for storage space-saving, sharing to YouTube, Facebook, Instagram, etc.

2. Windows Movie Maker

Though discontinued several years ago, Windows Movie Maker is still loved by many people for its lightweight video editing features. If you still have Windows Movie Maker on your computer, you can use it to merge videos together.

Step 1. Launch Windows Movie Maker, or download the archived version from website you trust.

Step 2. Select multiple videos and drag and drop them into the working area.

Step 3 (Optional). Rearrange the videos clips so that the combined video will playback in the sequence you like. You need to click on a clip and drag it to the spot you like.

Step 4 (Optional). Trim and remove unwanted sections from a certain video clip.

Trim Videos Before Combining Them into One
  • Under Video Tools tab, click Edit.
  • Click on the clip, and tick Split.
  • Click on the section you don't want, and hit Delete from your keyboard.

Step 5. Under the Home tab, go to Save movie, and choose an output setting. You can only save the video as MP4 or WMV. We recommend MP4 as it is widely compatible.

iMovie is the default video editing suite for beginners, and it is pre-installed in Mac. If you somehow deleted it previously (sure, it is a large storage hog), you can reinstall it from AppStore.

iMovie Tricks

If your video clips are in different resolutions, iMovie will adopt the resolution of the first video you dragged into timeline. Let's say you have one video in 1920x1080, another in 960x540, and you want the output video to be 1920x1080, make sure you drag that video firstly into the timeline. You can later rearrange it to other place, not necessarily in the beginning.

The drawback is, the output video will have poor quality if you upscale low resolution video clips. In that case, don't forget you can resort to Method 1 to merge videos at high quality, regardless of resolutions.
