LED step up to colour? how to get it smooth

Hi,

Are you setting the colour before they fade up or is the colour changing to the new one in the cue where they fade? If this is the case you can use the Mark function to set the colours on the units before they come up with the intensity.

Hi Dan

Thanks for your speedy response, we have auto marked the cues, so the colour changes happen on the previous cue.

The problem is when we want to have the LED's fade up/down to/from lower intensity, there is a very stilted fade up/down rather than a smooth transition. 

Is there anything we can do, or is it an issue with the fixtures? We're using Chauvet Slimpar Tri 12 LED lights.

Ah, I see. I'd have thought if you were getting a smooth fade with the wheel you should also get that from the cue as the calculations are essentially the same.

These units have no intensity control so Eos basically calculates the RGB values based on the colour and the virtual intensity your setting. If you're working with very low intensities you may get some variation in colour as the individual LEDs drop out. The only other comment is that they are only 8 bit, so there are only 255 steps for each colour which isn't a huge amount really you will likely see stepping at lower intensities.

I am  having exactly the same issue. As we are not using  them above 30% so I put a Curve on the intensity  to go 0-35 = 0%-100% this has helped. Moral of the story less than top of the range LEDs that do not have a theatre mode are not worth using in a theatre show. Will not make this mistake again.
