How to Put Two Videos Together: 11 Ways to Combine Videos

So you have two or more video clips and want to put them together quickly and easily. Merging videos can be tricky when clips come in different formats, resolutions, or devices, or when some footage needs trimming or cropping.

The good news is you do not need complicated editing software. This guide will show you step by step how to put two videos together and how to merge or combine videos on Windows 11/10, macOS, and iPhone. Using the methods here, you can combine clips from iPhones, DSLRs, GoPros, DJI drones, DVDs, ISO files, MTS folders, or ripped chapters into one seamless video without losing quality.

Putting Two Videos Together: Common Challenges

Before we walk you through the easiest ways to merge videos on Windows 11/10, macOS, and iPhone, it helps to be aware of a few common challenges:

• Your video clips may have different resolutions or aspect ratios. This can make the merged video look stretched, show black bars, or have uneven quality.
• Videos from different devices may use different formats like MP4, MOV, VOB, MTS, or ISO, which can sometimes prevent them from opening or merging correctly
• You might need to trim/crop some clips. If not, extra parts or awkward cuts could show up in the final video.

Don’t worry! The methods in this guide handle these differences smoothly, so you can merge or combine videos from different devices and formats without worrying about compatibility or quality loss.

Method 2. Use 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 MKV, MP4, AVI, and WMV 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. 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. (Optional)

• Click on the section you don't want, and hit Delete from your keyboard.

Step 6. When it finishes processing, all the video clips you have added will be merged into one MP4 video.

Method 3. Use QuickTime

QuickTime Player always surprises us of what it can do, and this time, it is the video file merging feature. You can also use QuickTime Player as a video merger. Follow the steps below to put together multiple videos into one.

Method 4. Use Avidemux

Avidemux is open source, and its UI is archaic. If you are using a 32 bit Windows, and have video files other than MP4 format, then Avidemux can be used as a temporal solution to merge videos together.

Step 1. Launch Avidemux, and click File > Open to add the first video.

Step 2. Click File > Append, or use the shortcut key Ctrl+A to add another video.

Step 3. Repeat Step 2 to add multiple videos.

VLC is one of the most widely used multimedia players with broad support for multiple formats and codecs. In addition to playing media files, VLC has many hidden functions, such as acting as a video merger. Besides using VLC from the command line to merge videos, you can also use the Wizard to transcode multiple videos. Follow the steps below to add together videos with VLC media player.

Step 1. Open VLC and go to "Media > Open Multiple Files…" from the top menu bar.

Step 2. Click the Add button to load the videos you want to merge to the program. Then click Convert in the drop-down list of Convert / Save in the lower right corner.

Method 6. Use FFmpeg

FFmepg is also a great tool which can help you with merging multiple video files. But quite unlike the applications above which only want you to input the files and will do the rest of the jobs, FFmpeg will require you some a little more professional skills. If you are new to this project, I will not recommend it for you at all. Anyway, here are the steps to make FFmpeg merge videos with the same codec in folder.

Step 1. Create a text file (for example, filelist.txt) and list the media files you want to merge, one per line:

• file 'input1.mkv'
• file 'input2.mkv'
• file 'input3.mkv'
• file 'input4.mkv'
• file 'input5.mkv'

Step 2. Run the following command. The merged file will be output.mkv.

• ffmpeg -f concat -i filelist.txt -c copy output.mkv

Tips: How to Merge Videos with Different Codecs

Step 1. Run the following command:

• ffmpeg -i input1.mp4 -i input2.webm -i input3.mov -i input4.avi -i input5.flv \ -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0][3:v:0][3:a:0][4:v:0][4:a:0]concat=n=5:v=1:a=1[v][a]" \ -map "[v]" -map "[a]" output.mkv

Step 2. [0:v:0][0:a:0] corresponds to input1.mp4, [1:v:0][1:a:0] to input2.webm, [2:v:0][2:a:0] to input3.mov, [3:v:0][3:a:0] to input4.avi, and [4:v:0][4:a:0] to input5.flv

Step 3. concat=n=5:v=1:a=1[v][a] indicates 5 input files and outputs 1 video stream and 1 audio stream named [v] and [a]

Step 4. -map "[v]" -map "[a]" output.mkv maps [v] and [a] to the final MKV file
