48'x18'

 You need to fit the resolutions aspect to the real world aspect you get to the screen.

48 x 18 is an aspect of 2,667:1 which means:

1200px height multiplied by 2,667 is 3200px width. This would need to be the total stage resolution: 3200 x 1200.
This results in an overlap of 33,28% respective 639px.

Your images have an aspect of 2,222:1, which won't fit to the screen you have.
If you would have a standard screen of 16:9, you would still won't be able to fit images with a different aspect. The stage would need to have the 16:9 aspect anyway, if you need to fill the screen. The same is true for blended screens.

Therefor you don't use the images / video aspects/resolutions as the basis for the stage, but the real world screens resolution.

@dusx thanks appreciate your help.. ive been using isadora since v1 on MAC.. so im in a world of hurt now with the giant rework

@demetri79

Unfortunately those actors are all supplied directly from the Apple core libraries and are not available on Windows. Most of what I see are video effects and you may be able to find some ffgl FX (or better GLSL) that are similar for Windows but you'll need to find replacements one way or another to get the patch up and running again on your PC.

I have a patch i made on mac which uses lots of CI and QC actors.. i moved my patch to my new beastly PC and realizing there are like 40 actors missing all CI and QC.. is there a way to get those somehow working on PC or am I out of luck and have to find equivalent (ish) replacements and rebuild the whole thing? I mean if it was a small patch no big deal.. but this thing took me years to build and is massive.. thanks

@dusx Awesome!

the manual for vs 4?

 It's nearly ready to be released. Very soon :)

For now the v3 manual covers most things and we have videos for a number of the missing topics. Beyond that we are always happy to answer question here.

@juriaan 

Thanks. I'd not discovered the Comparitor actor, I'll have a play with that, I can see this being useful for me moving forward. I've managed to get the right effect by limiting min and max values in the Control Watcher value parameters (0-8) then putting it out through a value changed actor with a min change of 5 and through toggle to switch effect bypass on and off when knob passes 8. Seems to work consistently. 

I have downloaded Isadora 4. I have found the manual for vs 3. Where can I find the manual for vs 4?

Thanks!

@dusx Thank you for the assistance. I will look into the display properties to adjust which image is "left" and which is "right."

BLENDING

The default belnding mask looks like this:

I have been adjusting the blend curve, trying from the gamma view and the x-y view. I can get the blend to be very smooth and provide a nearly perfect gradiation of the brightness between the two projectors. However, when this is set well, that is when I can see the distortion mentioned above.

@ainsleyphillips

Try to use a 2 Comparators, one with the mode set to gt (greater then) and the other to lt (lower then)

If you want to include the value 8, use 'le' (less and equal then) and 'ge' ('greater and equal then)
