Well, there is no true anamorphic project available and I doubt there ever will be, so what you need is to use MPC-HC and use the the numeric keyboard to adjust the aspect ratio (num8 to stretch, num2 ti shrink vertically) until the picture fills the screen - it won’t actually add resolution, of course, but it will make sure the AR is correct in anamorphic projection and you use all the light emmited by the projector). Alternatively, in VLC, you can set the cropping to crop off the black bars and then set the AR to whatever the AR of your projection is before the anamorphic stretch.
Thanks for the input yall. It was more a thought than anything. Ive been in the market for a new projector and have seen the anamorphic lenses starting to pop up in the HT market along with projectors that sort of emulate “constant image height” by scaling the 810 lines of vertical resolution to include all of the llight possible, making for a brighter image. I was just wondering if there was a fairly easy way to convert the current MKV file into a scope source and then let the projectors zoom feature stretch it back out into a 2.39:1 image. Just a thought.
