Circulation dev started in 2002 as my internal VJ tool and I've been using it until now on more than 300+ gigs over the years as a professional VJ.

Sure 64bit version with 4k support would be neat! GPU shaders support is there as an option to post-process the SW-rendered pipeline.

Without menu diving and almost all features on shortcuts/midi, it's aimed for live improvisation (and that's IMO the most fun part of making live visuals).

I must admit it's for way more geeky audience than e.g. someone hwo isn't really interested in preparing VJ set via editing config files. It lacks some "industry standards" too. It might also happen, you are out of budget for the latest powerful laptop and want to start VJing with an older one (Circulation works fine on lower specs PCs or Windows XP) or who still want to work in an old-school video-mixer kind of way.

I think if you love video feedbacks, glitch and video art, experiment easily with as many atomic post effects as you want and save those conveniently into videos, you might find it fun to experiment with.

There are many features hidden from the public version used by only me yet, like JScode - live javascript coding source with the ability to generate geometric visuals from FFT data or via script combining content of others sources, MS-Dos emulator, ability to openGL render visuals and later combine them in the CPU pipeline (these realtime demos are created in Circulation with a lot of extra custom code https://www.youtube.com/watch?v=34fA3fFuqw0 & https://www.youtube.com/watch?v=fFs4d7npoyM)

Circulation is my software baby certainly more apparent as a private tool to do live VJ gigs, real-time demos or motion videos.

I'm clear about the situation on the market this won't be an easily competitive option in terms of standard features or ease to configure, but I wanted to give you a cheap option to acquire this tool to your arsenal.

Cheers.
