My JVC RS2000 arrives on Monday, and I'm playing around with madvr in the meantime. I'm focused in particular on the devices portion of the setup, and was looking for a little help.
I have a 2.40 screen, and through madvr will only be watching blu rays and 4k discs (ripped to a server). The RS2000's native panel resolution is not the normal UHD resolution, but is instead 4096 x 2160. I have a panamorph DCR anamorphic lens, which I would like to leave in place all the time. My goal is to have madvr scale everything to 4096x2160, eliminate the top and bottom black bars on all 2.35 - 2.40 movies, and take into account the DCR (vertical compression) lens, so that I do not have to resort to using the JVC's various anamorphic scaling modes on top of madvr, to keep all movies in their original aspect ratios.
First step (I assume---correct me if I am wrong!) is to create output resolutions in the Nvidia control panel for 4096x2160 at 23, 24, 25, 30, 50, and 60hz. Next, I set LAV to use DXVA2 copyback so that I can enable black bar detection.
Where I could use some guidance is in madVR itself. Specifically, I need guidance on the "screen config" and "display modes" parts of the devices tab, and the "zoom control" tab under processing:
1) Under display modes, most people just specify 2160p23, 24, 25 etc. Because of my custom resolution, do I need to specify 4096x2160p23, 4096x2160p24, etc.? I assume yes.
2) Under screen config, I check "anamorphic lens" and "define visible screen area by cropping masked borders," but then what do I put in as the anamorphic stretch factor and the top and bottom cropping masked borders entry fields? For the anamorphic stretch factor, when I once asked
of Panamorph what the DCR lens requires, he said "4/3 vertical stretch, 16/15 horizontal stretch, 4/5 horizontal squeeze," but madvr only offers a single stretch factor box (I assume vertical?). For the cropping, do I need to create separate profiles for 1.78, 1.85, 2.35, 2.37, and 2.40 content, in order to crop different amounts of the black bars for each kind of film? Or is that better done in...
3) zoom control? I've got "automatically detect hard coded black bars" checked, and I've moved subtitles into the active video area. Currently, I have "notify media player about cropped black bars" and "crop black bars" checked. Should I check zoom small black bars away? Should I check "if there are big black bars . . . zoom the bars away completely"? Or do I need to create separate profiles here (and not at the screen config part) for different aspect ratios, and have different settings for each (I.E., either crop or zoom away black bars completely for 2.35, 2.37, and 2.40, and zoom small black bars away for 1.85?)
I don't fully understand how the screen config and zoom control interact, and which is better to use to achieve my goals, so any insight would be very much appreciated!
This is what
said, in an earlier instance where I was bumbling about some of these questions:
Yes, define your "display" to be a digital projector, then in the new "screen config" settings page check the "anamorphic lens" option. Furthermore check "define visible screen area by cropping masked borders" to define which part of the projector panel is actually visible on your screen, with the anamorphic lens in the light path. If you do all this correctly, any movies should automatically be scaled to have the correct aspect ratio through the lens, and fill the full screen (as much as possible).
You will probably also want to enable automatic detection of black bars (see processing -> zoom control) so that madVR will automatically detect and handle scope movies correctly.
What I need help with is the part of his statement that I need to "define which part of the projector panel is actually visible on your screen." Have you come across this before,
