I would like to echo some of the comments I have seen on this thread, which have stated that Dynamic Tone Mapping on JRVR MC31 is just amazingly good!!! Up to MC30, I have been using the last free version of madVR (113 ?), but JRVR in MC31 has surpassed the performance of that madVR version, and I have decided to use it all the time now ! Outstanding job, JRiver team !!!

I believe JRVR is heavily based on libplacebo. Hopefully, JRiver contributes to the project. In what way is the DTM improved vs JRiver 30 and MadVR 113?

Basically this is what I'm thinking right now, on a per-output basis in JRVR.
- Enable Black Bar Cropping
- Crop to [Automatic] (using the metadata), and [a list of common aspect ratios] (similar to whats available today in the context menu)
- Aspect Ratio Mode: Preserve, Stretch, Crop. Existing options as a per-output default. (moved from Video -> Aspect Ratio mode into per-output settings)
- Aspect Ratio adjustment, eg. a factor to adjust the aspect ratio by. Might have some presets and an input for a scale factor. This would be used for anamorphic lenses (or older screens with non-square pixels).
(this option was previously available in Video -> Aspect Ratio correction, this is moving it and making it per-output when using JRVR)
Advanced:
- Vertical Image Shift, Shift image to the top or bottom, rather then centered.
These are essentially all existing settings, streamlined into per-output settings in JRVR, and of course making use of automatic black bar cropping based on the metadata we're gathering now.

Thank you Hendrik for all the new features you are adding to JRVR, its much appreciated.
I would love to stop using my JVC NZ9 projector for my anamorphic stretch as the new model blanks on and off when I activate stretch so it isn’t pleasant. The previous model NX9 didn’t exhibit this blanking iussue and since I’m an X cinema projectionist I’m a bit of a presentation freak!
My only concern is would I be able to activate the JRVR stretch manually ON & OFF as I don’t want it activating automatically by itself? If it was only an automatic system I wouldn’t use it. For many it wouldn’t matter as most don’t have incorporated automated black side masking and a Cineslide for the “A” lens.
Please let me explain …
I use the playlist feature within JRiver which is a wonderful feature BTW, I make up an assortment of 3 to 4 trailers with different ratios > main feature…. Sometimes I prefer to show an odd scope trailer in 16:9 or 1.85 as many cinemas do before the main feature starts which might be scope. After the pre show the masking opens up to reveal the ScopE widescreen of the main feature, thereby adding impact.
I have many functions built into one button press for scope, Cineslide that moves the “A” lens in and out, black automated 4 stop masking for 4:3, 16:9, 1.85 and 2.35 scope, “A” stretch in the proj. That one button press changing from 16:9 to scope has all the “other” functions timed within mllliseconds of each other takes approx. 2 seconds and has impact!
I think for it to work for me it would need to be basically ON or OFF stretch, that I could build into Command Fusion 2.35 button. All I would need to do is remove the proj stretch from the 2.35 button and replace it with JRVR ON stretch, all the other buttons 4:3, 16:9 and 1.85 I would add JRVR OFF stretch. A keystroke assigned to ON and OFF would be all that’s required for me to use the new feature.
Im happy to offer any testing if you are in agreeance to a manual A stretch ON/Off function.
So in a nutshell to keep everyone happy, I suggest a manual way to operate the A stretch ON/OFF and maybe an automated way for those that don’t use Cineslides and automated black masking with multiple raitios.
