Hi!
I have a Constant Image Height projection system with a 2.35:1 aspect screen running in 1920x1080 resolution (Linux, nvidia).
Watching native 2.35:1 movies works great since the only thing projected outside the screen is the black bar (subtitles are moved up in video calibration).
However, some directors, like Christopher Nolan, thinks that switching AR between 2.35.1 and 1.77:1 is a great idea. Obviously, with my 2.35:1 screen, the 1.77 content is projected outside the screen which looks very crappy.
I then have two options:
1) Crop everything outside the 2.35:1 screen area (1920x816)
or
2) Scale the 16:9 image down so that the height fits inside my 2.35:1 screen
For most movies, 2 would be the way to go. But in this particular case, I would like to do 1).
In Windows, I solved this by adding a custom resolution 1920x816 and then by using video calibration I zoomed the image so that it would take up the whole screen width. The stuff outside the 2.35:1 frame would then be cropped automatically.
In Linux however, it seems that adding a 1920x816 modeline does not work. My projector rejects it and shows me "No signal". I guess that in Windows, the driver is actually sending out a 1920x1080 picture to the projector but allowing the OS to use 1920x816 only. Linux does not do this.
So I am thinking, is it somehow possible to "add" black bars to videos that have narrower aspect than 2.35:1?
Thanks in advance for your help!
