Is there a way to control the X & Y skew of a submix? I would need it for doing any sort of 2 or 3 screen projected panorama.

Is there a way to control the X & Y skew of a submix? I would need it for doing any sort of 2 or 3 screen projected panorama.
Set the mix to keystone and play to you hearts content.
(You can do this by going to the mix options window)
X & Y skew is not the same as keystoning. The problem is when your projector is not centered on your screen. The pixels will be closer together on one side, so you may correct the keystoning, but the pixels will not be proportionate. The skew squishes the content to either side to make it look like it's normal(yes... 'squish' is a very complex technical word... note sarcasm of my own choice of words). What video folks will roll their eyes at is that you should have done the math to get a straight on shot. The other is that you lose detail in the image because you sample some pixels and stretch them/squish them.
Sorry Andrew,how you know i can't speack inglish very well.
I'm sure using on mix keystone by manual or by Dmx (is much better) and
X-Y OFFSET (this is the command you need to use)with appropriate value(is possible custom value) together
Blending,you can do many and many wide screens type.
If you have particularly wide screen with linearity problem,you
need to use CURVED TEST where is possible to use a special manual keystone and is possible move linearity of the image in 16 different point.
I done projection in a BALL 3 mt. diameter using 2 mixes in blending
mode succesfully to cover 270° degrease with 2 videoprojector.
You have seen my little movies in the workshop.
Richard have seen my setup in "ANNOZERO" Italian Rai Television show
where used 2 CatV4servers and a 56 meters orizzontal widescreen
and 8 videoprojectors perfectly offsetted and keystoned.

(X-Y image movement) you can use together offset other command
like for example:
1) you can move X-Y the mixes by unlook it
2) you can move center image by unlook it
3) you can adjust image size by SCALE
Another important suggest is to do AUTO ADJUST IMAGE on the monitor
to have the mixes perfectly centered in the monitor.
This important to do it,every new computer and monitor start.
