Every other tool fakes HDR. VESAI masters it, scene by scene.
VESAI analyses your whole video, then masters real HDR10 from SDR: skin and midtones stay natural, highlights grow to your peak, bright skies and lights are controlled shot by shot, and MaxCLL / MaxFALL are measured from the result. One click for enthusiasts. Scopes, curves and full control for professionals. Plus AI upscaling up to 12K and frame interpolation.

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.

// REAL HDR, RIGHT IN YOUR BROWSER
SDR original vs VESAI HDR10
The right image is the real HDR10 master (10-bit, PQ, BT.2020), exported by VESAI as AVIF. On an HDR screen - Windows HDR on in Chrome or Edge, or a recent iPhone, iPad, Mac or Android phone - it shows in true HDR, with highlights far brighter than this page's white.

FURIOSA: A MAD MAX SAGA - Official Trailer 2 (Warner Bros. - Fair Use)
Not seeing a difference in brightness? Your screen or browser is showing the HDR image tonemapped to SDR. Turn on Windows HDR (Settings > Display > Use HDR) and open this page in Chrome or Edge, or view it on an HDR phone.
// NO HDR SCREEN? SEE THE DETAIL ANYWAY
The same idea on an SDR screen, through madVR
These are not the HDR images themselves: they are SDR simulations. Left: the SDR source. Right: the VESAI HDR10 master tonemapped by madVR at a very high target (about 900 nits), so the new highlight detail, specular lights, reflections and wider colour become visible on a normal screen. On an HDR display the master is far brighter than this.
SDR ORIGINALVESAI HDR · madVR SIMULATION
Highlight detail, fully restored. In SDR the clouds and lights sit at SDR levels: washed out, flat, no depth. In the VESAI HDR master the clouds get their texture back, the lights get real intensity and the whole picture gains depth and contrast.
THE HUNGER GAMES: SUNRISE ON THE REAPING (Lionsgate - Fair Use)
SDR ORIGINALVESAI HDR · madVR SIMULATION
Specular lights, reflections and colour. Not only more detail: the fountains, stadium lights and reflections become real specular highlights, the smoke colours open up with gamut expansion, and the coat and the crowd keep their natural tone.
THE HUNGER GAMES: SUNRISE ON THE REAPING (Lionsgate - Fair Use)
Why the HDR side looks darker here: an SDR screen can't show HDR brightness, so madVR compresses the whole HDR range into it to reveal the detail. On a real HDR display the same frame is far brighter, with highlights up to 1000 nits. Open the AVIF version on an HDR screen (Windows HDR on, or an HDR phone) to see it as it really is.
// 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 2.3.6 — SPECULAR ISOLATION
Speculars to the peak. Everything else stays comfortable.
Real HDR punch comes from small, very bright highlights. VESAI finds them on every frame and separates them from the large bright areas, pixel by pixel, automatically. In a grading suite, a colourist would do this by hand with a qualifier and a mask.
1000–4000
nits · speculars
Glints, lamps, reflections, sparks
Small, locally bright highlights rise to the full peak of your master: 1000, 1500, 2000 or 4000 nits.
350
nits · default ceiling
Skies, windows, white walls, lit faces
Large bright areas are held at the Highlight ceiling, so the TV's brightness limiter never pulls the whole picture down.
0
change · midtones
Faces, mids and shadows untouched
Only highlights are separated. Preview and encode are identical, and MaxCLL follows the specular peak.
Three controls: Specular isolation (strength), Highlight ceiling (100–4000 nits) and Specular peak (up to 10,000 nits). Ready presets for 1000, 1500, 2000 and 4000-nit displays.
// 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.

// 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.
