The free AVI MPEG WMV MP4 FLV Video Joiner is a Windows program that combines multiple video files into a single file for uploading to websites or for watching on a computer or mobile device.

The installation file comes as a free download. The Windows Setup Wizard walks you through the simple software configuration steps and adds the program to your applications menu, as well as giving you the choice of adding it to your Start menu, taskbar and desktop. To launch the video joiner, click the icon on your Start screen or just press the Windows key and type in the program name.

While the Free AVI MPEG WMV MP4 FLV Video Joiner doesn't come with any added features, it does what it promises in an extremely efficient way, using CUDA support from your graphics card to join videos up to 350 percent faster than CPU processing alone. The program also uses Microsoft DXVA technology to speed up processing, although to use either of these technologies, your computer needs a fairly new graphics card. Older machines could end up processing videos at the same slow rate as with other software.

Another benefit of omitting any unnecessary features is that the Free AVI MPEG WMV MP4 FLV Video Joiner has a simple, uncluttered interface that doesn't require any training. It supports dragging and dropping files into the editing panel, so you can drag files from anywhere on your computer to the video joiner and create a new video quite easily. You can even drag files from Dropbox or OneDrive if you have those folders installed on your desktop. Of course, if you just want to add videos in the usual way, you can search for them by clicking "Add Videos" in the program interface. If you're adding a large number of videos from a single folder, either method works very quickly.

After adding a selection of videos to the joiner, you can arrange them in the desired order by dragging them or by clicking Move Up or Move Down. This feature lets you create a playlist of videos to match your mood or join a series of clips into a full video. If you accidentally add a wrong video, you can remove it by clicking Delete, or you can remove all videos from the application by clicking Clear. If an unexpected problem occurs, you can access the help menu directly from the program interface by clicking Help, or you can view the program logs by clicking Log.

After you join a series of videos together, you can make sure your output video plays correctly by clicking Play in the program interface. This feature saves a little time by eliminating the need to open a separate application just to play your joined videos.
