This is a good starting point to study the basic structure of a video mixer in gem but can be / should be modded when you want to make a serious use of it. Remember also that the slider that goes into the 3rd inlet of has to be scaled between 0 and 1. IMPORTANT: Pix_mix just works with same size images or movies. Here we have two video players, one video mixer and the "output"
These are the basic elements you need to make the simplest two channel video mixer in gem: (not counting the VHS´s, dvd players, video monitors and so.) In pd it´s very practical to "emulate" that classic setup, one of the first benefits it´s that you can get rid of all that expensive hardware and do exactly the same function for a quarter of the price of a deccent video mixer. Modern video mixers have more inputs, more outputs, different mixing modes and effects. Into a VJ setup, it used to be a very important piece, because that was the machine that allowed to mix in a creative way video content from vhs´s dvd´s video cams, ipods, laptops w video output or any other device with a compatible output. basically, this machine combines the two inputs into a single output. A video Mixer it used to be a "hardware" machine.
One of the first things you can do with GEM it´s a "video mixer".
