Have you ever come across a situation in which you were watching videos, but constantly had to find and open a new one after finishing the previous one? While this sounds like a simple task, it can also be very annoying and time-consuming especially when you just want to view your content in one go without interactions. This kind of situation can also occur when you are creating a video, but probably end up with many different files, (for instance, when you are creating your own movie). No matter the reason, there will come a time when you need to combine or merge videos. Therefore, we will introduce video mergers in this guide, and we will also show you a comprehensive guide on how to merge the videos by using one of the software tools.

Part 1: What is MP4 Joiner & How to Choose MP4 Joiner?

Video merging is the process of combining multiple videos into one single video. Merging videos is useful if you are working on a project (for instance, an advertising video or a movie). It is also useful when you want to make a compilation of your videos for whatever possible reason. Therefore, an MP4 joiner is essentially a video merging software or SaaS (software as a service) that allows you to combine your videos. While it should primarily allow you to merge your videos, it should also have other characteristics. The following characteristics are what you should consider if you want to know how to choose mp4 joiner software;

  • The software should be multi-platform. You should not be forced to switch to another operating system for the merging job.
  • The software should support multiple file formats, including 4K videos (4K videos are the new standard of HD videos).
  • The software should incorporate video editing features.
  • The software should support batch processing, for faster video conversion if you have multiple files.
  • The software should preserve the original video quality.

Part 2: Six Best MP4 Joiners

While there are dozens of MP4 joiners available, from which most of them are free, we have rounded up a list of the best mergers that you can use for merging videos. Here is the list;

1. Leawo Video Converter Ultimate

This is by far your best bet for video merging. According to a Cnet Editor, “Leawo Video Converter Ultimate is a competent software, greatly enhanced by its ability…” because it integrates an advanced but very easy to use video editor. The tool gives you the ability to convert any video for playback on diverse devices, such as playing H.265 on Xbox One. In this case, Leawo Video Converter Ultimate will also allow you to merge videos, even if they are in different formats. It is also important to note that this software is built with support for over 180 formats, which makes it a perfect free avi/mpeg/wmv/mp4/flv video joiner.

2. Free Video Cutter Joiner

As the name suggests, Free Video Cutter Joiner is freely available and is conventionally used in cutting and merging videos. You can easily cut large video files and remove unwanted parts such, and you can also merge and combine various video files. It also supports multiple file formats, which also include FLV video. While this is all great, this software is a lightweight application and it lacks many features that come on most video converters. You also cannot edit your videos, and neither can you convert them to other video formats. This software is available on both Windows and macOS.


3. FaaSoft Video Joiner

FaaSoft is also another powerful free video joiner, that allows easy merging of videos together. You can combine videos of different formats, and merge videos and audios in similar formats. However, this software is not so user-friendly. Moreover, it does not support many file formats, which means your options will be limited if you wish to merge rarer file formats. This software is available for use on Windows and macOS.


4. iDealshare VideoGo

This software allows you to convert media files to playback anywhere you like. It supports many video formats, from SD and HD but it does not fully support 4K formats. Just like Leawo Video Converter, the application also comes with its own editor, which includes quite a variety of operations. It allows you to trim the selected video, crop, adjust brightness, contrast, and saturation, add text and picture watermark, and manage existing subtitles or add your own. In this case, iDealshare VideoGo can also merge your videos. It may meet your needs but it comes at a price because this software is not free of use. It is also multi platform, and it works on both macOS and Windows.


5. Apple iMovie

iMovie is a powerful video-editing program that among other things is primarily built to turn your iPhone-recorded video footage into stunning movies. It can also merge your videos, just as long as the format is MP4, MOV or the few other video formats supported. Because of Apple’s strict policies, you cannot merge other formats like FLV videos and the likes. Moreover, you have to be in the Apple ecosystem to use this software. While the interface is simple, this software is also not an easy software to use for newbies, and you will have to fiddle around with it to know how it works.


6. Cledio

If you prefer not to download and install apps, you can do the conversion job in the cloud directly from your web browser. Clideo is such kind of service, an online tool that you can use to merge videos. As with all online video converters, you will need a strong and steady internet connection for uploading and download videos. You should also know that the free version has a limiting maximum file size of 500 MB, but the good thing is the service offers paid tiers (Clideo Pro) if you wish to convert larger files. Clideo Pro will cost you $9 per month for unlimited videos, or $72 per year for unlimited videos.

Part 3: How to Merge/Combine MP4 Files with Leawo Video Converter Ultimate

We introduced Leawo Video Converter Ultimate as the best video merger because it has a lot more rich features which you can learn about from the product page. Therefore, download and install this software on your computer to do the merging job. The software is available for Windows and macOS, and below are the conversion steps for your reference.

Step 1: Import the source videos

Click on the “Add Video” icon to import the videos or directly drag them to the main menu. If your videos are stored on a disc, insert the corresponding disc into your disc drive and import them. Once the videos have been imported, then you can see them on the list.


Step 2: Select the desired output format

According to your needs, there are multiple output formats to choose from. Click the “MP4 Video” box, and from the drop-down list, select the “Change” option. On the Profile window, select a format of your choice under “Format” (You can choose normal, HD and even 4K for the quality).


Step 3: If you need, edit the videos

Click the video editing icon which is placed next to each video, to enter the editing menu (you can trim, watermark, convert 2D videos to 3D etc).


Optional: Adjust video parameters

Click the “Edit” drop-down box instead of “Change” in the main menu. It includes “Video Codec”, “Bite Rates”, “Resolution”, “Frame Rate” and “Aspect Ratio”. Adjust them accordingly. You can also adjust the audio parameters.


Step 4: Start merging the videos

Return to the home page, where you should find a “Merge All Files to One” button on the top right corner. Make sure all the files have been added to the list of the video converter. Then, click the “Merge” button and you will be required to set the “Save to” route. Finally click the “Convert” icon to start the merging process.


You can use any of the six video mergers that we recommended above. While each one of them has its own advantages and disadvantages, we think Leawo Video Converter Ultimate is the best tool to use in this case. That is because it has a lot more features, and its just so easy to use.
