Hi there, I’m a beginner to vvvv, I’ve been reading all the tutorials, and looking around here but seem to have run into a confusing problem.
I have a number of videos collected together in a grid, they are each 256 by 256. My output resolution from my renderer is 1920 by 1080, so I used a Scale x of 0.5625 on the View Transform pin of the Renderer. This makes sure it’s square and the right aspect.
My confusion comes from the Transform node going into the Quad node.
It seems it only works as I think it should when I have the Scale x and Y pin of the transform node both set to 0.5.
But surely it should work set at scale 1? But when I set it at this, each video is displayed way too big on screen which seems bigger than 256 by 256 pixels. I’m confused?
You should scale transform your quads, not your renderer.
So delete the Scale node on your renderer.
Learn your spreads and use the cross node. The table you made is the same as a linear spread, width = 2, spread count = 4.
The scale of your quad would be: 2/4 = 0.5
2 = the scale you need to make 1 quad fill the entire renderer.
4 = the ammount off quads you want in your grid.
0.5 = the x-scale and y-scale for 16 quads in a grid.
The screen resolution has not much to do with this.
Quick question you put my screen resolution in your patch as 1920 by 1096, is this intentionally not the actual size of 1920 by 1080 or are you just testing me ? :)
I tried your method in my patch but it squeezes everything, is this because your Renderer EX9 is set at in x 1024 by 768? and mine is 1920 by 1080
He he, I can see I’m wasting screen space but I don’t know what else to do!
I want to project this at the end onto a wall, I made each video square at 256 by 256 because I read that this was an efficient texture size, and in doing this it means my end result is square. I mean I could add more videos to fill the entire space but I worry that playing back that many will grind things to a halt
You could try the preloader node and use the 75 textures of every clip :P , it´s a good way to make fast scratch with video, if not you can just play the videos with the VLC plugin or FileStream, but this last one is not spreadable.
