This is a must-try program, especially if you are passionate about digital video and video editing. Mixing video is that operation that is seen on television especially when watching music videos, when one fades the image and begins to see the next one, gradually entering the foreground.
Programs that mix videos in this way are the famous Virtual DJs or Epic DJs that are not free at all.
In this case, however, we are not talking about a mixer program, which treats videos as if it were music, but of (experimental) software that allows you to mix different videos, live or real time, even from different sources and without audio.

The ideal use of GL Mixer would be to unify the filming, live, made with different cameras, during an event or a live concert in a single video.
Basically, if you had different shots, you could unify and mix, in real time, by mounting a single video that uses and exploits the different shooting angles.
GLMixer can mix a series of videos and images in such an easy way that allows any user to mix different movies.
Even if you are unlikely to be dealing with live concert footage, it can be fun to try GLMixer using the videos you have on your computer now and see what you can do by mixing them.
GL Mixer is free, still in beta, for Windows, Linux and Mac and installs normally.
After opening it, you can see an empty sphere inside which the videos are loaded.
From the Sources menu you can add a series of " media files " that are on your computer or even video streamed live from a video camera or webcam, and you can decide, in real time, how they should be viewed on the screen .
The circle in fact represents a kind of visual orbit and by placing the videos inside they overlap while moving them with the mouse outside they are excluded.
If you change the way you view the arrangement of the videos graphically, putting them, for example, in 3D levels, you can realize how easy it is to mix the different movies and overlay them.
Each of the 3 views allows you to dynamically and easily manipulate one or more sources differently.
If you don't try, it's probably difficult to understand what I'm talking about.
A simple practical example would be to upload four videos and arrange them on a grid so that all four are visible at the same time.
You can then try to change the transparency, to overlay only a part of the video, to move an "off screen" video, to display only a section, to rotate, resize and zoom.
Various effects can be applied, such as adjusting saturation, brightness, color, adjusting the alpha channel, applying a mask, adding noise, applying filters such as relief, sharpness, blurring and inverted color.
You can also group several videos together and work on them at the same time.
However, each operation, modification and effect is visible in real time in a separate window which, ideally, should be displayed in full screen on an external monitor or in a projector.
The sore points are two: you cannot save a video but only the project (which always opens with GL Mixer) and the sound in the video sources is ignored, therefore no audio is heard.
GLMixer is a lot of fun to use and can also be useful in certain circumstances.
It deserves to be tried because it is free and because it is really easy to use.
To mix videos, on Windows, the only free program that comes to mind is the ideal Windows Movie Maker for editing .
If you are looking for something different, I remember, in other articles, the best programs to mix music like a dj and also the YouTube video mixers which, however, are far from giving a real mixing effect.
