HDR Video Delivery, Done Properly

HDR video delivery is the last and least forgiving stage of a high dynamic range project: turning a finished grade into files that carry brighter highlights, deeper shadows and a wider color range to the viewer intact, in formats such as HDR10, HLG and Dolby Vision. When it goes right, a sunlit window glows the way it did on set and a night scene keeps its detail. When it goes wrong, the same film plays gray and washed out on one television, clipped and garish on another, and gets rejected outright by a platform that expected different metadata.

It matters to anyone commissioning or producing video that will be watched on modern phones, televisions and streaming services: brand and product teams, agencies, documentary producers and in-house video departments. HDR looks striking on the right screen and wrong on the wrong one, so a proper delivery includes the correct metadata and, in almost every case, a separate standard dynamic range (SDR) version made on purpose rather than left to an automatic conversion.

This guide follows one illustrative project from brief to delivery. The client, the film and every number in it are a composite example built to show the decisions involved, not a real engagement. At each step we explain what was decided, why, and which trap it avoided, so you can apply the same reasoning to your own HDR work.

The Brief: A Product Film That Had to Look Right in HDR and Everywhere Else

The illustrative client is an outdoor equipment brand launching a new line of tents and headlamps. They wanted a three-minute hero film for their YouTube channel, a 30-second cutdown for paid social, a looping version for in-store displays and a muted version embedded on the product page. The creative idea leaned heavily on contrast: dawn light over a ridge, the glow of a headlamp inside a tent at night, sun glinting off a lake. That is exactly the kind of imagery HDR was designed for, and exactly the kind that punishes a careless delivery.

The first meeting was not about the look. It was about where the film would actually be seen. The marketing team assumed "shoot it in HDR" meant every version would be HDR. In practice, only some destinations could display it, and several would convert or strip it. Listing every destination, and what each one accepts, before a single frame was graded shaped every later decision.

The deliverables list that came out of that meeting looked like this:

• YouTube hero film in HDR, because YouTube accepts HDR uploads and serves an SDR version to viewers whose devices cannot display it.
• A matching SDR master of the hero film, graded deliberately, for the website, client presentations and any platform that does not handle HDR.
• A 30-second paid social cutdown in SDR only, because the ad placements the client planned to buy did not reliably accept or display HDR.
• A store display loop in HDR for the specific large-format screens the retail team had already purchased, after confirming those screens accepted HDR10 over their media player.
• An archival mezzanine of the HDR master with full metadata, so future edits and re-exports would not need to start from the camera files.

Two points from that list recur throughout the project. First, HDR is a per-destination decision, not a project-wide switch. Second, the SDR version is a real deliverable with its own grade and its own quality check. If you want a structured way to gather these requirements for any project, our guide on getting video delivery specifications right covers the questions to ask each platform and stakeholder.

Choosing Between HDR10, HLG and Dolby Vision for This Delivery

HDR television is defined by ITU-R BT.2100, published by the International Telecommunication Union, which pairs high dynamic range transfer functions with the wide BT.2020 color space. Within that framework there are two transfer functions and several delivery formats built on them, and the choice among them depends on where the video is going and how it will be produced.

The PQ (perceptual quantizer) transfer function, standardized by SMPTE as ST 2084, maps code values to absolute brightness. A given value means a given number of nits on the display, which makes PQ precise for mastering but dependent on metadata to tell a consumer display how to adapt content it cannot reproduce. HLG (hybrid log-gamma) is a relative transfer function developed for broadcast and designed to be compatible with SDR displays: an HLG signal shown on an SDR set still produces a watchable picture, which is why broadcasters favor it for live production.

For the illustrative project, the reasoning ran as follows. The hero film was a finished, graded piece going to on-demand platforms, not a live broadcast, so HLG's main advantage (a single signal that works on SDR screens without metadata) mattered less than precise control over highlights. HDR10 was chosen as the primary HDR master because the store screens and YouTube both accepted it and it needed no extra licensing. Dolby Vision was considered, since its dynamic metadata and trim controls described by Dolby Professional would have given finer control over how each shot mapped to dimmer displays. It was deferred because none of the confirmed destinations required it and the budget favored spending grading time on a proper SDR pass.

That is a reasonable default for many brand and marketing projects. Dolby Vision becomes the stronger choice when a streaming distributor or broadcaster specifies it, or when a film has wide swings in brightness from scene to scene and the team wants shot-level control of the tone mapping rather than trusting each television's own.

Capture Decisions That Kept the HDR Grade Possible

HDR delivery starts on set, because a grade cannot reveal highlight or shadow detail the camera never recorded. The illustrative shoot used cinema cameras recording a log profile to a 10-bit or higher codec, which preserves the latitude HDR grading depends on. An 8-bit recording of the same scenes would have left too few code values to spread across an HDR range, and smooth gradients like a dawn sky would have shown banding once stretched. Our article on video bit depth decisions explains why 10-bit is the practical floor for HDR and when 12-bit or raw is worth the storage.

The camera team made three specific choices with HDR in mind:

• Exposure for highlights, not just skin. In SDR a clipped sky often disappears into white and nobody notices. In HDR, a clipped highlight shows up as a flat, featureless patch that is noticeably brighter than everything around it. The camera operator checked false color and the waveform to keep the brightest important detail, such as sun on water, just below clipping.
• Recording raw on the key night scenes. The headlamp-in-tent shots combined a very bright source with deep shadow. Recording raw on those setups gave the colorist more room to hold detail in the fabric around the lamp and in the dark hillside behind it. For the tradeoffs involved, see our guide to getting raw video formats right.
• Controlling practicals. Visible light sources, such as lanterns, screens and the headlamps themselves, become far more prominent in HDR. The crew used dimmers and neutral density gel on some practicals so that the light sources read as bright but not searing.

None of this is exotic. It is careful exposure with the knowledge that the final display may show a range several times wider than a standard monitor on set.

Setting Up the Grading Suite and Color Management

The single most important rule in HDR finishing is to grade HDR on a monitor capable of displaying it. A standard computer display or an SDR broadcast monitor cannot show what a PQ signal at 800 or 1,000 nits looks like. A colorist grading HDR on such a screen is guessing, and the guesses tend to fail in one of two directions: highlights pushed far too hot because they look fine on the limited monitor, or a timid grade that wastes the format.

For the illustrative project, the grading suite used a reference monitor capable of sustaining 1,000 nits across the frame, calibrated for PQ with a P3 D65 gamut inside a BT.2020 container. That combination, a 1,000-nit mastering display limited to P3 primaries and delivered in a BT.2020 signal, is a common professional baseline because it matches what the better consumer displays can reproduce while keeping the signal format consistent with BT.2100. The room was kept dim and neutral, since room light changes how contrast and saturation are perceived.

Color management was set up before any creative work:

1. Input transforms converted each camera's log encoding into a common wide-gamut working space, so shots from different cameras started from the same reference.
2. A scene-referred working space held the grade. Working in a wide-gamut, scene-referred space means the creative decisions are made before the image is squeezed into any particular display format.
3. Output transforms rendered the working space to the HDR output (BT.2020 primaries, PQ transfer, limited to a 1,000-nit peak) and, separately, to SDR (BT.709 primaries, BT.1886 gamma, 100 nits).

This structure is what made a genuine SDR grade practical later. Because the creative grade lived in a display-independent space, producing the SDR version meant switching the output transform and then trimming, not rebuilding the look from scratch.

Grading the HDR Master Without Blowing Out Every Highlight

The most common creative mistake in HDR is pushing highlights to the maximum on every shot. It is tempting: the format can go brighter, so why not use it? The result is a film that is tiring to watch, where every window, sky and reflection competes for attention and there is nowhere for the eye to rest. On consumer televisions that cannot reach the mastering peak, it also forces heavy tone mapping, which compresses exactly the detail the colorist was trying to show.

The illustrative grade followed a few working rules:

Keep diffuse white close to SDR territory

Industry guidance on HDR production commonly places reference or diffuse white, such as a white shirt or a sheet of paper in normal light, at roughly 200 nits rather than at the display's peak. The colorist kept faces and diffuse surfaces in that neighborhood so that the overall picture brightness felt natural and consistent with SDR viewing, and reserved the range above it for things that really are brighter than white: the sun, specular glints, light sources.

Use peak brightness sparingly and on purpose

The dawn sequence let the sun's rim touch the upper part of the range. The headlamp in the tent peaked lower, around the middle of the available headroom, because a full-brightness point source in a dark frame is uncomfortable on a large television in a dark room. Most shots in the film never came near 1,000 nits at all. That restraint is what makes the few bright moments land.

Watch average light level, not just peaks

A frame can have modest peaks and still feel glaring if large areas are bright. The colorist tracked the frame-average light level alongside peaks, and pulled back wide shots of snow and sky that pushed the average up, even though no individual pixel was clipping.

Protect shadow detail without lifting blacks

HDR's deeper shadows only help if there is detail in them. Night scenes were graded so that the hillside and tent fabric kept texture on the reference monitor, then checked for crushed or noisy blacks. Where the raw footage showed noise in lifted shadows, light noise reduction was applied before the grade rather than after, since HDR tends to make noise in dark areas more visible.

One further safeguard mattered here: not grading for the reference monitor alone. A shot that looks spectacular at 1,000 nits in a dark suite can be harsh on a bright living room television and muddy on a phone at low brightness. The colorist regularly toggled a simulated lower-peak view during the grade and flagged shots whose appeal depended entirely on peak brightness.

Building the SDR Version as a Deliberate Second Grade

Many HDR projects fail not in HDR but in SDR. Automatic conversion from HDR to SDR, whether by a platform, a player or an editing tool, has to make generic assumptions about how to compress a wide range into a narrow one. Sometimes the result is acceptable. Often, skin tones shift, highlights turn gray and flat, saturated colors clip or go muddy, and the careful contrast of the HDR grade collapses.

The illustrative project treated SDR as its own deliverable with its own review. After the HDR grade was approved, the colorist switched the output transform to BT.709 at 100 nits and worked through the film shot by shot. The process:

• Re-balance highlights. The dawn sun and lake glints, which had room to breathe in HDR, had to be rolled off gently into SDR white. The colorist adjusted the highlight roll-off per sequence so detail in bright clouds survived rather than clipping to a flat white.
• Recover midtone contrast. Compressing the range tends to flatten the image. A modest contrast adjustment in the midtones restored the sense of depth without crushing shadows.
• Check saturated colors. The tents' bright orange sat comfortably inside BT.2020 and P3 but pushed outside BT.709. Those shots were adjusted so the orange read correctly in SDR instead of shifting toward red or clipping.
• Match to the HDR intent, not the HDR numbers. The goal was for the SDR version to feel like the same film: the same mood, the same direction of the eye. It was never going to look identical, and trying to force it to would have produced a flat, compromised picture.

On YouTube specifically, the platform's help page on uploading high dynamic range videos explains how HDR uploads are handled and how an SDR version is produced for viewers on non-HDR devices, including options for guiding that conversion. The team reviewed that guidance and tested the conversion with a short sample before relying on it, rather than assuming the automatic SDR stream would match the separately graded SDR master.

A skilled colorist is central to this stage. If your team is producing HDR and SDR masters for the first time, our creative video editing service includes grading and finishing for both versions from a single timeline.

Encoding and Metadata: Where HDR Video Delivery Usually Breaks

Once the grade is approved, the files have to leave the grading system with their HDR identity intact. This is where many projects that looked perfect in the suite end up washed out on YouTube or on a client's television. The pixels are fine; the metadata describing how to interpret them has been lost or mislabeled along the way.

What the metadata has to say

Every HDR file needs, at minimum, correct signaling of three things: the color primaries (BT.2020), the transfer function (PQ or HLG) and the matrix coefficients (BT.2020 non-constant luminance). In QuickTime and MP4 containers these are carried as color tags, and in HEVC streams they are carried in the video usability information. If a file is tagged as BT.709 while containing PQ-encoded pixels, a player will display it as SDR and the picture will look flat and gray.

HDR10 adds static metadata for the whole program:

• Mastering display color volume, which describes the primaries, white point and minimum and maximum luminance of the display the program was graded on (in the illustrative project, P3 primaries, D65 white, 1,000 nits maximum).
• MaxCLL (maximum content light level), the brightest pixel in the program, in nits.
• MaxFALL (maximum frame-average light level), the highest average brightness of any single frame, in nits.

These values let a consumer television decide how to tone map a program it cannot display at full range. They should be measured from the finished master, not typed in from memory. In the illustrative project, the grading software analyzed the timeline and reported the MaxCLL and MaxFALL figures, which were then carried into the delivery encodes. A program with honest, measured values gives a television better information than a guess.

The encode chain

The project exported a high-quality intermediate first, then encoded delivery files from it. The mezzanine was a 10-bit ProRes file at the full UHD resolution with BT.2020 and PQ color tags and HDR10 metadata attached. Delivery encodes for YouTube and the store screens were then made from that mezzanine in 10-bit HEVC, which supports HDR signaling and is widely decoded by televisions and media players. Our articles on HEVC video and video codecs and compression explain the encoder settings that matter for quality and file size.

Every transcode is an opportunity to lose metadata. Some tools write color tags only if explicitly told to; some drop HDR10 static metadata unless specific options are set; some convert to 8-bit by default. The team's rule was to inspect every output file with a media analysis tool and confirm primaries, transfer, matrix, bit depth, mastering display values, MaxCLL and MaxFALL before it left the building.

Platform-by-Platform Delivery and Quality Control

With files encoded and verified, delivery went destination by destination, because each one handles HDR differently. The table below summarizes the illustrative project's approach.

A few decisions deserve explanation.

The website received SDR only. HDR playback in browsers depends on the operating system, the browser, the display and its settings, and behavior varies. A muted autoplay loop on a product page gains little from HDR and risks looking wrong on a large share of visitors' screens. The SDR master, encoded in H.264 for broad compatibility, was the safer choice. Our guide to embedding video on websites covers the rest of that decision.

Paid social received SDR only. Delivering HDR where the platform or player only supports SDR is one of the classic mistakes, and ad placements often re-encode uploads in ways that are hard to predict. For the cutdown, a clean SDR file gave the client consistent results across placements.

YouTube received HDR, then was checked twice. HDR processing on YouTube can take longer than the standard versions, so the team waited for the HDR version to appear and then reviewed both the HDR stream on an HDR television and the SDR stream on a standard laptop screen before announcing the video.

Reviewing on Ordinary Phones and Televisions, Not Just the Reference Monitor

A reference monitor tells you whether the master is correct. It does not tell you what customers will see. The final quality stage of the illustrative project was a structured review on consumer devices, because tone mapping on phones and televisions varies widely by manufacturer, model and picture mode.

The review set included an HDR-capable phone, a standard phone without HDR playback, a laptop with an SDR screen, a mid-range HDR television in its default picture mode and a brighter HDR television set to a more accurate cinema or filmmaker mode. Each device played the version its viewers would actually get, through the actual platform where possible.

Two issues surfaced in the illustrative review. First, the end-card graphics, which had been designed at full white in the HDR timeline, were uncomfortably bright on the brighter television. They were reduced to sit near diffuse white, which is common practice for graphics in HDR. Second, one dawn wide shot looked slightly gray in the automatic SDR stream on YouTube even though the separately graded SDR master looked right. The team tested YouTube's documented options for guiding SDR conversion on that sample and settled on the approach that brought the automatic version closest to the approved SDR grade.

Neither issue would have been caught on the reference monitor alone. That is the practical case for consumer device review: it is where the delivery is tested against reality.

Where the Time Went, and When to Bring in Help

In the illustrative project, grading the HDR master took about four days, and the SDR grade took two more. Encoding, metadata verification, consumer review and uploads filled the remaining days. Teams new to HDR are often surprised that the SDR work and the checking take as long as they do, but that is where most of the visible failures are prevented. A rough breakdown of effort, again illustrative, is shown below.

The drivers in the right-hand column matter more than the proportions. A single-camera interview with even lighting needs far less HDR attention than a landscape film with sunsets and night interiors. A project with one HDR destination is simpler than one with five.

Signs you need specialist help

Bring in an experienced HDR finishing team when:

• A platform or distributor rejects your HDR deliverables and the reason is not obvious from the error.
• HDR uploads look washed out, gray or dim, which almost always points to lost or incorrect metadata somewhere in the chain.
• A project needs both HDR and SDR masters and nobody on the team has a monitor capable of displaying HDR.
• A distributor specifies Dolby Vision and you do not have the workflow to analyze, trim and deliver its metadata.
• Graphics, subtitles or archival footage have to be integrated into an HDR timeline and keep looking consistent.

Our video editing and production team handles HDR and SDR finishing, metadata verification and platform delivery, and can take over at whichever stage your project needs. For more on related finishing topics, browse the video editing and production articles.

The Reusable Lessons From This Project

Strip away the specific film, and the illustrative project leaves a sequence of decisions that apply to almost any HDR job.

1. List every destination first. Decide HDR or SDR per destination, confirm each one's accepted formats, and test on real hardware where a spec sheet is vague.
2. Pick the HDR format from the destinations, not the other way round. HDR10 is a sound default for on-demand delivery; HLG suits broadcast and live work; Dolby Vision earns its place when a distributor requires it or when shot-by-shot tone mapping control is worth the workflow.
3. Capture for the range you intend to deliver. Log or raw in 10-bit or higher, with highlights protected and practicals under control.
4. Grade HDR on an HDR monitor. Keep diffuse white near SDR levels, use peak brightness sparingly and watch average light level.
5. Grade SDR on purpose. Build it from the same color-managed timeline and review it as its own deliverable.
6. Protect the metadata. Measure MaxCLL and MaxFALL, tag primaries, transfer and matrix correctly, and inspect every file after every transcode.
7. Review where viewers watch. Phones, laptops and ordinary televisions, after platform processing has finished.

HDR rewards preparation more than any single piece of equipment. The best-looking HDR films are rarely the ones with the brightest highlights; they are the ones whose makers knew exactly where each version would play and checked that it arrived intact.
