Drag the slider. That's real HDR.

Same frame, same display. The VESAI HDR10 master keeps skin and midtones true to the source and adds real highlight range: speculars, lamps and city lights rise toward the peak while large bright areas stay comfortable.

All masters below use the default VESAI Studio SAFE Film 1000 nits preset, a tone curve matched to UHD Blu-ray grades. One slider sets your own peak: SAFE presets for 1500, 2000 and 4000 nits are included, and HDR Nits goes up to the full 10,000-nit PQ range. Shadows, midtones and skin keep the same look while highlights, speculars and lights scale into the new range. Every setting stays fully customisable.

How to read it: the signs, lamps and screens get real HDR intensity while the street, the bridge and the people stay at a natural level, the way a studio HDR grade does it. All values are measured on the HDR10 files themselves. Seeing no brightness difference? Turn on Windows HDR and use Chrome or Edge, or open the page on an HDR phone.

// NEW IN 2.4.1 · WIDE GAMUT ACCENTS

Skin-safe BT.2020 colour. Only where it belongs.

Most SDR-to-HDR tools either keep the colour inside Rec.709 or P3, or push everything wider and give you neon faces. VESAI does what a colourist does: only colours that are already very saturated and lit (neon signs, tail lights, lasers, fire, coloured lights) go past DCI-P3 toward the BT.2020 primaries, at the same brightness. Skin, skies, greys and everyday colours stay natural.

BT.2020

wide colour · accents

Neon, lights, lasers, fire

The most saturated, lit colours of the hues you choose (red, orange, yellow, green, cyan, blue, magenta) are stretched past P3, out to the BT.2020 edge.

change · skin tones

Faces protected

Skin tones from light to dark, even under orange street light, are left exactly where they were. Pale and mid colours, skies and greys are not touched.

Live

A CIE 1931 scope in the Colour tab shows the SDR source next to the HDR output. Pixels past P3 show in magenta in the gamut report. Preview and encode identical.

VESAI gamut view: colours outside Rec.709 and outside DCI-P3

VESAI Colour tab with Wide gamut accents and the before / after CIE scope

On this frame the official UHD itself puts 3 % of the picture past P3. VESAI, from the SDR alone, reaches 5.9 %, on the signs and lights only. Best seen on wide-gamut HDR displays (QD-OLED, high-end mini-LED); other screens map it into their own range.

// NEW · VESAI MATCH

Measured against the studio master. Not guessed.

Give VESAI the SDR source and the official 4K UHD HDR release of the same film. VESAI Match lines them up, measures in real nits how the studio's colourist mapped every brightness level, the shadows, the gamut and the colour, and sets VESAI's HDR engine to follow that grade, with a report you can check. As far as we know, no other software does this.

01 · ALIGN

Two releases, one timeline

The SDR and the UHD are aligned automatically, frame pair by frame pair, letterbox and framing included.

02 · SAMPLE

The whole film

Frames are sampled from start to end, and every frame counts the same, so one dark scene can't decide the grade.

03 · MEASURE

The colourist's choices

Brightness per SDR level from shadows to speculars, shadow handling, gamut expansion, colour balance and the disc's own peak (MaxCLL).

04 · MASTER

VESAI follows the grade

Curve, shadows, colour and highlights are set and checked against real renders, then saved as a reusable VESAI Match preset.

UHD brightness range	VESAI vs official UHD
0.05 – 0.5 nits	+0.08 stop
0.5 – 5 nits	+0.10 stop

±0.1 stop

Within a tenth of a stop of the studio master across the whole brightness range, from deep shadow to highlights, with higher peaks.

More than a copy. VESAI follows the studio's grade, then its own highlight engine works on top: on this sunset the sun gets a defined, glowing core and the wrecked train car keeps its metal texture and edge light against the haze.

A growing library. Every match is saved as a VESAI Match preset with the film, the camera and the nits, ready for films graded the same way.

// NEW IN 2.3 — HOW VESAI MASTERS HDR

It watches the whole video before it touches a pixel

No fixed filter applied blindly to every frame. VESAI measures your video first, then builds the HDR master from what it found.

01 · ANALYSE

Every shot, every scene

Detects every shot (fades, dissolves and flashes included), reads the source range and measures the light in every scene, so the HDR never changes mid-shot.

02 · MASTER

VESAI Studio Tone

A studio-grade SDR-to-HDR curve built from your target peak. Faces and midtones stay where they were; highlights expand smoothly. Big glowing lights and skies are held back automatically, while glints and sparkles keep the full peak. With Specular isolation it happens pixel by pixel.

03 · DELIVER

Measured HDR10 metadata

MaxCLL and MaxFALL are measured from the actual converted video, not guessed, so TVs and players display the highlights correctly instead of clipping them.

// NEW IN 2.4.1 — LIGHT CORES & SAFE SPECULARS

The lamp gets its core back. Everything else stays comfortable.

In SDR the core of a lamp, the sun or a fire is clipped together with its glow. VESAI finds those light sources scene by scene and lifts the core above its glow, separates small speculars from large bright areas pixel by pixel, and holds big skies and white walls at a comfortable level. In a grading suite this takes qualifiers, masks and keyframes. VESAI does it automatically.

Light cores

automatic · per scene

Lamps, sun, fires, sparks

Each frame's brightest light gets a soft, defined core above its glow, with no halos or pasted look. Strength adjustable from subtle to strong.

600

nits · large bright areas

Skies, clouds, white walls

Measured scene by scene and held at a comfortable level at 1000 nits (scaled with your peak), so the TV never dims the whole picture. Small lights keep the full peak.

Safe

always · for your peak

Speculars that never break

Specular isolation always stays inside a safe range for the HDR Nits you choose: skin and normal whites are never touched, speculars never halo.

Master at 1000, 1500, 2000 or 4000 nits: shadows, midtones and skin keep the same look while highlights, speculars and bright areas scale into the new range. The default VESAI Studio SAFE Film presets follow a tone curve matched to UHD Blu-ray grades.

// VESAI COLOUR SCIENCE

Built on HDR standards. Tuned by VESAI.

Real HDR10 mastering, not a filter: SDR decoded with BT.1886, mastered in BT.2020 with PQ (SMPTE ST 2084) output and measured MaxCLL / MaxFALL.

BT.1886BT.2020PQ · ST 2084BT.2100OKLABHDR10

01 · HUE-TRUE EXPANSION

Colours stay true

Brightness is expanded without changing a pixel's hue or saturation, so saturated colours don't shift or bleed as they get brighter. Only colours that would exceed the peak are eased gracefully toward white, like a real HDR master.

02 · HDR-NATIVE COLOUR

Colour processed in HDR

Colour is processed directly in the HDR signal, not in SDR. Skin tones, shadow colours and highlights keep their hue at every brightness level.

03 · PERCEPTUAL GRADING

Oklab colour vectors

Gamut expansion and six-vector hue and saturation controls can run in Oklab: pushing saturation or turning a hue never changes how bright a colour looks.

04 · VESAI ENGINE

Per-scene tone curves

Every shot is measured and the expansion adapts to it: highlights, large bright areas, depth and shadows. VESAI's own tone curves, scene by scene.

HDR10

// THE INDUSTRY PROBLEM NOBODY TALKS ABOUT

Fake HDR is everywhere. Real HDR is only here.

Most "SDR to HDR" tools boost brightness, crank contrast, and repackage SDR inside an HDR container. The dynamic range never changes.

😤 What most software does

Amplifies SDR brightness and calls it HDR
Colors stay trapped in BT.709 gamut
No real expansion of dynamic range
One filter on every frame — no scene analysis
Metadata copied from a slider, so TVs clip the highlights
No real-time preview: render first, pray later

✅ What VESAI does

Analyses the whole video and masters every scene on its own
Studio tone: natural skin and midtones, real specular highlights
Large bright areas held back automatically, glints keep the peak
Hue-preserving colour in a BT.2020 container, safe gamut expansion
MaxCLL / MaxFALL measured from the result + Dolby Vision workflow
Preview rendered by the encode engine, with HDR scopes

// HOW VESAI COMPARES

We compared the main SDR-to-HDR tools. None does all of this.

AI converters don't analyse the video: they convert each frame as it comes. Grading suites need a colourist. VESAI analyses the whole film and masters it, with the controls a professional expects.
