I'm a relatively long time Max/MSP user but have only recently begun working with Jitter.

I am having issues with a seemingly simple patch. The effect I want to achieve is a continuous shift through the color spectrum, from red to orange to yellow to green, etc.. and back to red. I want to play this on a fullscreen mode and/or record this to a movie.

I implemented the following patch based on the helps/tutorials. It works but there is some "jumpiness" to it at certain moments, that also translates into the movie if I record it. I have tried to detail & comment the patch to make it easier to diagnose - you can change the rate of rotation through the colors and this jumpiness seems to occur at any/all rates.

Any ideas on how to make this color shifter work more fluidly would be well appreciated.

off the top of my head you could do this with some basic Jitter effects on the video stream:

•trying [jit.slide] with low up/down setting

•or if you are feeling a little more fancy dig out the gaussian blur from Andrew Benson's video processing patch tutorials.

these should smooth the jumpy changes that happen when rendering the values in [jit.lcd] - I'm not noticing jumpiness on the longer timescale settings in yr patch.

let me know if there get you somewhere...

•or if you are feeling a little more fancy dig out the gaussian blur from Andrew Benson's video processing patch tutorials.

also have a look at the jit.gl.render erase_color, it will be light on cpu then lcd

Thank you very much for your suggestions. I will let you know how they worked out as soon as i get a chance to test them out.
