Video Combiner: join multiple videos on Windows
Video Combiner is a free portable software program for Microsoft's Windows operating system that you may use to merge multiple videos easily.
Windows users have plenty of options when it comes to the joining of video files on the system. From using the command line to join multiple video files to third-party programs like Cute video Audio Merger or Vidiot.
Video Combiner is a third-party program that is dead easy to use and still very powerful. It accepts many popular video formats as input and may turn these into a single output format.
Note: The free version of the application adds a watermark to the video. You may want to use the alternatives mentioned above instead. We have adjusted the rating accordingly to reflect this.
You may run the portable version of the program directly after you have downloaded and extracted the archive it is supplied as.
To get started, drag & drop video files into the program window to add them to the process. You can click on the add button as well if you prefer to use a file browser to add video files.
Video Combiner supports a large number of input video formats including mp4, avi, mkv, mpg, mov, or flv. One of the greatest strengths of the application is that it accepts different formats; you can add mkv, mp4 and mov files and all of them will be merged into a single output format that you select during setup.
A click on the up and down arrow icons moves the selected video in the list; this is useful if video files are not in the desired order.
The main output options are displayed at the bottom of the interface. There you set the desired output format for the merged video, the screen size and other options.
The screen size setting supports different presets including fit max width, fit min width, or min width & min height, but also a custom size that you need to enter manually. There is also an option to scale videos which ensures that there won't be any black bars in the output video.
Video Combiner retains the original display aspect of every video by default and that may result in black bars if the input videos had different aspect ratios.
The bitrate is set to default when you start the program but it is unclear what it is set to. You may change that to other presets or a custom bitrate instead.
The two final options enable full CPU acceleration on 64-bit systems and let you change the output directly.
Video Combiner supports multiple output formats including mp4, mkv, ts, vob and avi. You can pick any of those.
A click on the combine videos now button starts the merging process. The length of the process depends on several factors including the size and length of the selected videos, their format, and the output settings.
I ran a few tests with several sample video files to test the application. It worked well with single video formats and multiple video formats. The size of the output was usually larger than the size of the input files; four mp4 video files that had a size of about 140 Megabytes were turned into a 240 Megabyte file by the application when I used the default output settings (mp4, fit max height, default bitrate); the output file size dropped to about 140 Megabytes when I switched to fit the minimum height instead.
It may be necessary to test several settings before you find the right one that suits you best. The conversion process was quick but it certainly depends on the input files and output settings as well as the system you run the software on.
The program can be useful to combine multiple video files, e.g. all episodes of a TV show or Holiday videos that you want to combine to create a merged video out of them.
Video Combiner is dead easy to use: just drag & drop some video on the program window and hit convert. Inexperienced users may have some difficulties understanding settings such as bitrate or even output format, but there are only a few and the online help explains most of them.
