[Feature Request] JRVR - Black Bar - Shift Image
« on: April 27, 2023, 03:13:54 pm »

Any chance of adding a feature similar to the one in madVR? I have a 16:9 screen and mask the bottom for wider 2.35 movies.

I second this. I use a PJ with a fixed 16:9 screen and I use the "move image to the bottom of the screen" feature of MadVR and it's awesome.

I would like the to be able to have the image moved when black bars are detected (and for it to support dynamic resolutions, just like MadVR does). I don't find it jarring at all when there's resolution switches. It makes for an amazing experience when your 2.35:1 image jumps to fill the screen.

This is the one thing that's stopping me moving to JRVR from MadVR.

the description of features planned is in https://yabb.jriver.com/interact/index.php/topic,135621.0.html

the approach is to use offline analysis to determine the location of black bars which means it will never be live in the way madvr does it (unless jrvr fundamentally changes approach), at present use of this info is manual (using the set aspect ratio UI option) but I believe the plan is to automate this & drive that via jrvr profiles.

How do we move the play/stop/pause toolbar from the top to within a 2:35 aspect screen? This is probably my only issue when using an A lens for scoped screen. 

I have to switch my project back to 16:9 so that i can see the toolbar which is annoying.

You could use the TheaterView "OSD" instead of the StdView "Top Bar"?.  Any MCE remote should do the trick.  Alternatively, if using a keyboard, the up/down arrow keys bring the menu up.  Left/Right arrow is back/fwd.  Play/Pause is the space bar.

see this thread https://yabb.jriver.com/interact/index.php/topic,135745.0.html

right now, you need to use the option

Options > Video > Advanced > Aspect Ratio Correction > 1.78 output to xxx display

since this is a zone setting you may also need to use zoneswitch to be able to route scope content to this zone and 16:9 content to another zone (that doesn't have this enabled)

if you need to do this, you also need to create a custom field which derives the cropped AR so you have a simple way to detect the aspect ratio. To do this, I created a calculated data field using this expression

Code: [Select]
formatnumber(math(math(listitem([Video Crop],2,x) - listitem([Video Crop],0,x)) / math(listitem([Video Crop],3,x) - listitem([Video Crop],1,x))),2)you must have run "detect black bars" for this to work and this rounds to 2 decimal places

if you call this field CropAR, a zoneswitch rule would then be something like

[=Compare([CropAR],>,2.3)]=1

in order to choose scope content

hopefully this moves into JRVR and becomes largely automated sooner rather than later

Thanks Matt, I did see that. I guess I'm asking (hoping) for that fundamental approach change.
The static bar detection seems to be aimed at the use case where there's an ultrawide display which would benefit from having the image scaled to fit it better.

All I'm highlighting is that there's another use case, those of us that want to move the image within a 16:9 screen. Static bar detection doesn't solve for that case.

Static bar detection doesn't solve for that case.

Knowing where the bars are is an important step for all of those functions, otherwise there can be no automatic change.

PS:
2.35:1 can never fill a 16:9 screen unless you are happy to lose some image on the sides. And if thats what you like, you can combine the future black bar detection with the "Crop" scaling mode, and it'll fill the screen just fine.

Thanks for the reply.
I'm not trying to zoom the image, I don't want anything cut off.

What I use the black bar detection to do is to move the 2.35:1 image to the bottom of the 16:9 screen. So I have one large bar at the top of the screen and the image is flush to the bottom of the screen. This is much, much less distracting than having black bars top and bottom, and still works really well with the change of aspect ratio in Nolan movies (and others

It's also easier to mask with a single masking panel at the top rather than having to have masking panels top and bottom.

I'm also hoping for black bar detection. It's a must for me with variable aspect ratio films when using a 2.35:1 screen. Either that or a way to blank the image (Epson projectors cant do this). Until then I'll have to stick with madvr.

Do you mean changing zoom throughout the film?

This is exactly what I'm doing except I have a single masking panel for the bottom. It works better for my room to move the image up. JRVR is probably a no go for me until there is a way to handle this easily.

I have madvr set to black bar detection. When a 2.35:1 film suddenly changes aspect ratio, instead of the image overhanging my 2.35:1 scope screen, it's shrunk to fit. Not sure how it works but it works  :).

I am referring to variable aspect ratio films, you want it to change or pick one?

Either, not bothered. 'Pick one' would be cool. As long as it fits the screen with no drama.  :)

Been playing with JRVR on my TV tonight. Really happy with the simplicity. It didn't like the NVIDIA driver (385.28) I was using at first when playing HDR material, kept crashing my GPU.

For films that are shot in multiple aspect ratios, madVR adjusts the necessary shift on the fly so that there is always a single black bar on either the top or the bottom. Depending on how different the ratios are, that sometimes forces me to forego the masking since it would cover too much of the image during the taller portions. One of the more recent Mission Impossible Fallout sticks out in my mind as having a few scenes that were in an IMAX ratio while the majority of the movie was not.
