Constant Width question

Leaving out the pros and cons of constant width vs constant height I am wondering if the following set-up is possible with any current 1080P projectors:

Setting up the projector for 2.35:1 (say 54 x 127) with an anamorphic lens in place, and proper video processor, and adjusting the proper zoom and focus setting into memory 1 of the projector.

Remove the anamorphic lens and keeping the same throw distance adjust zoom and focus for 16:9 screen 72 x127 and setting into memory 2 of projector.


Could the above be done to automate a constant width setup on a screen 72 X 127 with masking ?

Correct so I get 100% of the panel by scaling and anamorphic lens for 2:35 and also 100% panel for 16:9, and have a constant width setup.

Totally confusing on my part, let me try and clarify

Is it possible to set the projector up with an anamorphic lens and scaler for 2.35 at 54x127 and also set if from the same throw distance, remove the anamorhic lens and adjust via Zoom and other projector adjustements to 72x127 image?

In other words 2 independent settings from the same throw distance:
1) anamorphic lens in place scaling a 54x127 image
2) no anamorhic lens and a 72x127 image

Is the above possible?

Thanks, the above is not possible with a HE compression lens and adjustments?

Thanks again so to do constant width with a 72 x127 16:9 screen I would move a Vertcal Compression lens in place and scale for 2:35 Scope 54x127, and by simply removing the lens from the equation I would have full resolution 16:9 @ 72x127, with no zooming nor scaling required ?.

I understand this is the Constant Image Height forum, is it possible to have a sub forum for the few who are interested in discussing Constant Width or Constant Area?

This is where I am lost why would I need to scale a 16:9 Image for a 16:9 projector on a 16:9 screen?

Correct I think I got it, with VC lens in place scale for scope, with VC lens removed 16:9 without scaling or zooming!!
