Changing Movement Speed During Movement?

[Pinspot]

Hi everyone,

 

I wanted to find out if it is possible to change the speed of movement from point A to point B. I know right now if I want to set a speed I just change the speed with the wheel. Lets say I set a light to take 3sec to get from point A to point B so I program this and the light takes 3 sec. Now my question is during those 3sec is it possible to change the speed where the light starts out moving fast toward point B but ends up slowing down just before it gets to point B. I know that when you program a light it moves at a constant speed from point A to point B but I want to be able to change that speed during those 3sec. Im using a Fatfrog to do this.

 

Thanks

The best method for this would be to program the movement as a single-shot chase. First you need to decide how many steps you're going to require to make a smooth movement. The simplest implementation of this will be for a 2step chase.

 

S1 - Original Position

 

C2 - Step1 - Three quarters of the way to new position

C2 - Step2 - In new position

 

Set the second memory up as a chase, continuous crossfade, set the Shots to [1] and Position to [Fade]. Play with the speed control to obtain a reasonable speed for the fade.

 

If you've got generic (HTP) fades happening at the same time as this movement, you'll need to program them at 50% of their end value in Step1 and at their end value in step 2.

 

 

Hope this makes sense

you could also do this with memories. Making a memory with postition A and a memory with position B. On the playback x fader is a fade override control with wich you can slow down or speed up fading time during the fade itself. Don't know if this also works on the ltp fade time though.
