Hello, I have some questions about dimmer curves.
If I do not select a curve, which curve does EOS use by default?
Which Curve is best for Fresnel lights like a Mole 5k, 2k or 1k? What curve is best for a Source Four Pars and which Curve is best for regular house hold light bulbs?
I tried the Incandescent curve on our lights and it lowered their intensity quite a bit, What is that Curve meant for? I am starting to think maybe it's for emulating an incandescent and shouldn't be applied to them but I am interested in finding out what the actual answer is.
The curves is to bend a transaction between 2 states after your will.
A example: I have along slow fade from black and a lot of LED lights. They go bright fast and in a slow fade you get the feeling it…
A curve is how a value reacts to your input.
I think the default is zero = zero and full = full and a straight line between the two.
you can use curves for all sorts of things
running a flicker or a stagger over the entire cue (or part of) as the lights fade (easier than building an effect and a follow on.
changing the start value if (for instance) the units only start to eminate light at 40%
changing the way LED units fade
snapping out shutters
etc etc . . . .
look at the non dim at full and non dim at 50 curve and see that they do just what they say.
They're easy to edit too, copy one to another and input values at other values (I cant remember the syntax but sure someone else on here will get back to you/ tell me where Im wrong ) ;)
A example: I have along slow fade from black and a lot of LED lights. They go bright fast and in a slow fade you get the feeling it jumps on and the last bit not much is going on. To get a smooth fade I applied a curve to that cue where the start is slow (Think it is curve 902)
If you do not mix a lot of fixtures types (LED, incandescent and so on) where you feel the way they fade relative to each other you do not normally need curves.But if you run LED and incandescent in sidelights as a example you may want to apply a curve to the LEDs so they do not fade on faster then the incandescent.
All this should be done before programming starts. What happen to you is that you applied a curve that is slow in the start as a incandescent light to your incandescent lights, making them slower and there fore at low values giving out less light.
The "non"curve is giving out 1:1 all the way. when the input say 10% the output will say 10% to. A slow start curve may say in 5% out 1%; in 10% out 5%; in 20% out 12%; in 30% out 26% slowly catching up to In 100% out 100%. (In what you say the level of the channel is, out is what the dimmer/fixture actually get)
Here is a video on curves https://youtu.be/OUpPa5JY1M4?t=147
I think you're both saying that the curve is only supposed to affect the light when it's transitioning through fades. (We have a problem with some lights flickering unintentionally, someone suggested I change the curves to fix the flickers.) So I changed the curves for our lights all to incandescent and there was a tremendous drop in light output, even when set to 100% the lights were not as bright as they are with no dimmer curve set. So now I'm wondering what is that profile actually meant to do? I took a peek at it in the curve tab and the line does eventually reach 100% there, so I'm confused.
if the curve reaches 100% the output with curve and without curve should be the same if the intensity is set to 100.
can you check if there is a proportion set in Patch>Attributes? that could make the channel not reach 100% even if Live display says 100.
i don't think a curve can solve any flickering when there is no transition happening.
Thanks for your help. I didn't have a proportion set but I took a look at the Incadescent Curve after you explained it and saw that the Input/Output was really low. 60% on the Console was only 38% on stage.
I'm starting to understand. Thank you
