What’s the difference with VISIONPLUS, Dolby Vision and HDR10 Video?
There are some huge differences and benefits VISIONPLUS HDR can offer to the public and we are going to explain it.
- +Deep Blacks
- +Realistic Highlights
- +More Details
This is the unreleased Skyfall 007 Movie mastered in VISIONPLUSHDR-X.
Video is recorded using Mirillis Action! Software from the MadVR HDR Processing.
This is the unreleased War For The Planet Of The Apes Movie mastered in VISIONPLUSHDR-X.
Our VISIONPLUSHDR-X is technically better than most studio grades.
As today, Studios don’t master the HDR Grade to it’s best and this is the main reason a lot of movies are not considered good looking.
To get an idea on how weak can be a studio HDR grade we will use one of the best commercial grades.
Some “reviewers” and people, call latest Guardians of the Galaxy VOL. 2 HDR Grade a “reference” quality.
This movie grade got crushed black details and over saturated pixels.
Don’t believe us? We will show you with simple images.

This comparison has been made by one of our members of the private community.
He did not use the same exact frame, but you clearly get the idea.
Disney HDR Grade is far from being “reference” like some people claims over the internet and forums.
This grade is actually noobish and disrespectful to the actual HDR meaning and goal.
Disney literally applied a heavy contrast mask to the HDR grade for the goal to achieve a “fake” higher contrast.
They have also saturated the pixels for the goal to achieve again a “fake” color gamut in the dark scenes.
Basically, the HDR grade is poor and made in purpose like that due to the fact they still don’t know how to do a proper HDR grade.
Our transfer, shows all the details in place and the gamut is not over saturated with the native 2020 colorspace rendered.
Actual HDR TVs are not really HDRs but SDRs. Why?
For a video to be HDR it has to be REC. 2020 Compliant but you need several requirements detailed below:
- Video Codec HEVC H.265
- 10 to 12-BITS Color Depth
- BT.2020 Matrix and Primaries
- PQ ST. 2084 or HLG * Hybrid Log Gamma *
- MaxCLL / MIN / Mastering Display metadata
The HDR video is primarily a GRADING that needs to be transferred to an extended range of color and gamma curve PQ SMPTE ST. 2084/2020 for our HDR standard.
This is how HDR10/Dolby Vision also works.
The video grading can be from any NITS peak to the maximum of the PQ SMPTE ST. 2084 which would come to be 10,000 NITS.
Currently the best high-end TVs for example Samsung’s 2017 4K UHD HDR Line can achieve a real peak of 2000 NITS in their panels.
In such a way the Blu-Ray commercial HDR vary in their type of grading and metadata:
- HDR10: 1000 to 4000 NITS peak with static metadata.
- Dolby Vision HDR: Peak of 4000 up to 10000 NITS with dynamic metadata.
Coming generation with ST. 2094 Metadata is going to add dynamic range and color to the HDR10+ and Dolby Vision.
As you can see the movies people can buy are indeed limited by their type of grading, which means they are not “pure” HDR movies.
The worst case scenario would be the HDR10 Movies with only 1000 NITS Peak Grading, pretty close to SDR standards with such low grading, as the average nits would be close to the 300 mark. ( SDR is 100 nits peak ).
In the future when you can buy TVs with a higher peak of real NITS these films will be out of phase.
The movie studios will invent another version (OR NOT) of the movie with the highest peak of grading in NITS, which result in more economical gain for the movie studios and a bit of unpleasant to the movie lovers.
A current HDR TV is actually SDR in Steroids (Standard Dynamic Range):
- HDR native container peaks at 10,000 NITS.
- The films they sell now have a peak at 1000/4000 as explained above.
- The HDR TV’s that can be purchased today the most top of the range got real peak at 2000 NITS.
So what happens when we play a Dolby Vision movie on a TV that has a technological limit of 1000 NITS panel and the movie is 4000 NITS graded?
Basically the TV software (a chip in the case of Dolby Vision) limits the NITS of the video to fit the actual panel limit: 1200 NITS or less if it is a TV with lower panel capacities. This is called TONE MAPPING.
This would have to be the most reasonable scenario for HDR10 Movies, since most peaks at 1000 NITS and a good Ultra HD HDR TV from today can actually do it. So you get the “real thing” in the output, unless you have got a panel with less than 1000 NITS where compression is used.
There’s another scenario for the Dolby Vision or VISIONPLUSHDR-X graded movies.
What the software does is return to SDR in HDR10 when panel can’t get the actual 1000/4000 top peak nits to output the native HDR video. This means compressing the HDR and convert to SDR. ( Tone Mapping ).
By using TV Presets HDR10 can look extremely over saturated or with over brightness, since the video has got a really low NITS Grading when using TV presets things can become unnatural and unrealistic. Daylight scenes will also look too dim and unrealistic due to the low nits grading and TV processing applied.
Today with VISIONPLUSHDR-X you can get to playback native HDR without the restrictions from the companies/movie studios.
MADVR software (well known among digital movie fans) can process NATIVE HDR content when detected by the software.
MADVR can fully process the HDR signal just like TV’s do, but without the GAMUT / Gamma Curve / Dynamic Range / NITS limit.
You can also playback 10-bit DirectX 11 Fullscreen Exclusive with the help of LAV Filter in CPU decoding mode/Nvidia 10-Bit Capable GPU.
It even offers tweaks you are able to setup such as the Preserve HUE/Compress HighLights/Restore Details/PurePower Gamma Curve and so on.
You get HDR video in pure state with a lot of tweaking options, instead only having to choose from factory made HDR TV Presets.
As of today you can also playback VISIONPLUSHDR-X using the Windows 10 HDR API ( in MadVR you select “passthrough HDR to TV using Windows 10 API” or Movies & TV Player.
Why HDR is being used as pure marketing
TV and movie companies are making the HDR a scam and a trade. People think they buy TV’s HDR. When in fact, any panel up to a monitor can play an HDR video. The main idea of HDR is ancient in photo edition.
They limit the PQ (HDR format) to take long term TVs and sell them as “new” giving the HDR a simple top grading.
The TVs only have the necessary nits to meet a luminance requirement of the HDR grade, the HDR is based on contrast, gamut, range and deep blacks, besides the highlights that would come to be the part where the NITS of a TV can give greater luminance.
The luminance in an HDR video with a TV that outputs more NITS, will also be noticed in the same way in an SDR video. It is understood?
The HDR TV does not exist.
What do exist is the HDR video standard, with the help of a HDR software processing it can be “decoded” to your panels.
