Jerky movement when using Enttec USB Pro

Postby JR Roughley » Thu Oct 25, 2007 8:53 pm

Hi Guys

I am using Enttec DMX Pro

All works well! Except when I want to move the image around on the screen like I would a moving light beam. The movement is not very smooth even with DMX smoothing at 255.

Any ideas if I can get smoother movement any other way.

Thanks

Hello,

Be sure that you right patched arkaos on your dmx console, all the position channel are in 16bits, then use smooth movement on your console.

best regards

Hi guys.

There is a factor that you have to take into consideration, when moveing visuals around the screen and the jerky movement.

the problem is that Dmx 0-100% is really calculated in hexadesimals. and that is 0-255. so the the ratio of pixels horizontaly or verticaly in the movement. so an image crossing the screen will always run jerky as a screen of 1024 x 768. 1024/255 = 1hexadesimal = 4pixels. or something like that.

thats why some people are asking for a timeline in arkaos. for smoother movements and timeings for effects.

I hope this is correct. and it helps.

cheers
