Using Any DVD Converter

Download the video clips you want to join. If you are trying to merge multiple YouTube clips together, you'll need to download them to your computer first. Visit keepvid.com and enter the addresses for each of the videos you want to download. Select the highest quality MP4 format video from the download options to download the file to your computer.
Install Any DVD Converter. You can download the free version of Any DVD Converter from anvsoft.com. You can also use the free version of Any Video Converter from the same company, and the process will be exactly the same.
Start Any DVD Converter. Start your trial if prompted when using the free version. You'll be taken to the Convert Video tab of the program.
Add the video files that you want to merge. You can drag and drop files into the main frame, or you can click the "Add Video(s)" button and browse for video files on your computer. It may take a few moments to add large files.
Click and drag videos to reorder them. The combined file will be in the order that the videos are listed in, starting with the top of the list.
Adjust the length of the clips you want to use. Click the Scissors button next to the clip you want to edit. A new window will open, allowing you to skip to the exact spot you want. Set a new start point for the clip by clicking the "[" button, and the "]" button to set an end point.
Select all of the video clips. Once you're satisfied with the order and the length of the clips, select all of the files in the list. You can do this by holding Ctrl/⌘ Cmd and click each one, or you can press Ctrl/⌘ Cmd+A.

Right-click on the selected clips and select "Merge all files". The videos will be merged together, with subsequent videos indented beneath the first clip. Select the first video in the list before proceeding.

Select your output format. Click the Output Profile drop-down menu at the top of the window. Select the device that you are planning on playing the video on. If you're going to play the video on a computer, or want it to be compatible with the most devices, select "Customized MP4 Movie (*.mp4)".
Set your output folder. Click the folder icon in the Output Folder line in the right sidebar. Make sure "Basic Settings" is selected to see the Output Folder button. Select a folder that you can easily access and find your merged video file.
Adjust your output settings. The wrong settings could lead to a bad file or could cause Any DVD Converter to crash. Adjust your settings before you start the merging process.
Start the converting and merging process. Right-click on the top file in the list and select "Start Converting". Any DVD Converter will begin merging the clips into a file in the location and format you specified.[1]
Merge small batches at a time to prevent crashes. Any DVD Converter can get overloaded with too many clips. If you're having problems merging many different clips together, it's recommended that you do them in small batches and then join the batches together.Method 2 of 2:
Using Avidemux

Download and install Avidemux. Avidemux is a free, open source video editing program, and you can use it to merge clips of any length into a single video file. You can download Avidemux from fixounet.free.fr/avidemux/.

Open your first video clip in Avidemux. Launch Avidemux and click "File" → "Open". Browse for the first video clip you want to use.
Append the second video clip. Click "File" → "Append" and select the second video file. After you select it, it will be added to the end of the first video clip.
Repeat for additional clips. You can keep using the "Append" command to add more clips to the end of the video file. You can't easily adjust the order later, so make sure you add them in the order you want.

Save the new file. Click "File" → "Save" and save your new video file. It will be saved in the format of the original video. The encoding process may take a few minutes to complete.[2]
