What Is HDR (High Dynamic Range) Video? A Guide for Editors

HDR (High Dynamic Range) video captures and displays a much wider range of brightness and color than traditional video. For professional editors working on high-end projects like commercials or films, HDR can create eye-popping visuals, but it also introduces new technical challenges.

HDR vs SDR: More Luminance and Color

Standard Dynamic Range (SDR) video is the traditional format (for example, Rec [709]. color space, 8-bit color). In contrast, HDR video extends both the brightness range and the color gamut.

• Bit Depth: HDR workflows typically use 10-bit or higher color depth, allowing more subtle gradations than the 8-bit color depth common in SDR.
• Color Space: HDR video often uses wider color spaces like Rec [2020]. or DCI-P3, showing more saturated and varied colors compared to Rec [709]. in SDR.
• Brightness Range: HDR captures and displays much higher peak brightness (for example, 1000+ nits) while also preserving deep blacks. This creates greater contrast and more detail in highlights and shadows at the same time.
• Footage Types: HDR footage is often shot in RAW or log formats (like S-Log or V-Log) to preserve detail in extremely bright or dark areas for grading.

Together, these factors mean HDR footage looks more vibrant and lifelike than SDR when viewed on an HDR-capable display.

Why Shoot in HDR?

Many professional projects benefit from the extra dynamic range. Shooting in HDR (often in log or raw modes) captures more visual information across the brightness spectrum. This is especially useful for high-contrast scenes, like a sunrise with a bright sky and a dark foreground, or nighttime cityscapes with neon lights against deep shadows. With HDR, details are preserved rather than clipped—so you can see more texture in a bright sky and more information in dim shadows simultaneously.

Using HDR footage can make the final video look more cinematic and polished. It’s becoming critical for high-end films, premium commercials, and streaming content (Netflix, Apple TV+, etc.) that support HDR output. If viewers have an HDR TV or monitor, they’ll notice deeper blacks and more realistic highlights that add a “pop” to the image. In short, HDR can significantly elevate the production value of your project when done correctly.

Editing HDR: Workflow and Requirements

Editing HDR video requires the right tools and setup. First, you need an HDR-capable monitor. This is usually a professional 10-bit display that can reach higher brightness levels (many are rated at 600 nits or more). Calibrate the monitor to standard HDR targets (for example, Rec [2020]. color primaries and a known brightness curve) so that colors and luminance are accurate. Without a proper monitor, you may misjudge exposure or color until it’s too late.

Your video editing software also needs to support HDR workflows. Most modern editors do. For example, DaVinci Resolve, Adobe Premiere Pro, Final Cut Pro, and others let you set a project to an HDR color space (such as Rec [2020]. with a PQ gamma curve, or Hybrid Log-Gamma for HLG). In Resolve, you might enable the ACES color science or use the HDR scopes on the color page. Premiere has HDR Lumetri scopes and can tag the timeline as Rec.2020/PQ (HDR10) or HLG. Always double-check your project/sequence settings to ensure everything is set for HDR, not mistakenly left in Rec.709.

While grading, use HDR-aware scopes and monitoring tools. Many NLEs include waveform monitors, histograms, and vectorscopes that extend beyond the standard 0–100 IRE range, showing you if any color is going out of gamut or exceeding brightness limits. These scopes help you track levels beyond SDR’s range, ensuring you aren’t blowing out highlights or crushing blacks unconsciously. By working in a color-managed HDR space, you can adjust exposure and color confidently, knowing how the image will appear on actual HDR screens.

Tone Mapping and Multiple Deliverables

A common challenge with HDR is delivery. HDR content played on a non-HDR display without conversion will often look wrong (usually flat or overexposed). To avoid this, editors typically produce separate HDR and SDR versions.

Most editing and color tools offer tone mapping or color space conversion to create an SDR version from your HDR grade. For example, you might color grade your master in Rec.2020/PQ, then export an SDR copy by applying a Rec.2020-to-Rec [709]. tone map. This remaps brightness and colors into the limited SDR range so the video looks natural on regular displays. Some editors even maintain two timelines or sequences: one graded in HDR color space and one for SDR (or use a dual-output color-managed workflow like ACES).

When exporting the final HDR master, include the correct HDR metadata (often called mastering display metadata). This metadata tells HDR TVs how to interpret your video. Key values include the color primaries (e.g. Rec.2020), white point (usually D65), and peak brightness/luminance numbers. HDR10 requires static metadata fields like MaxCLL (Maximum Content Light Level) and MaxFALL (Maximum Frame Average Light Level). Dolby Vision, on the other hand, uses dynamic metadata for each scene or frame. Make sure your export settings fill in these fields properly. For example, DaVinci Resolve allows you to enter mastering display info and content light levels during delivery. Accurate metadata helps ensure your HDR video looks consistent across different devices.

HDR Formats and Compatibility

There are several HDR formats you might encounter or need to deliver:

• HDR10: The most common HDR format, using 10-bit color and static metadata. It’s widely supported by TVs, monitors, and streaming services.
• HLG (Hybrid Log-Gamma): Designed for live broadcast, HLG is backwards-compatible so that HDR TVs show it as HDR and SDR TVs show it as normal-looking SDR (no extra metadata needed).
• Dolby Vision: A premium HDR format with dynamic metadata on a per-scene or per-frame basis. It can deliver an even wider brightness and color range, but requires specific tools and licensing.

When planning a project, clarify which HDR standard(s) your client or platform requires. For a streaming client, HDR10 or Dolby Vision might be targets. For broadcast or cable, HLG could be preferred. In any case, always plan on delivering an SDR version too. Many viewers don’t have HDR-capable screens, so a Rec [709]. master (or Rec [709]. Blu-ray) is often needed. For example, you might deliver a 4K HDR10 master along with a 1080p SDR Rec [709]. master, or vice versa depending on requirements. Having both ensures your content is viewable everywhere.

Common Issues & Fixes

Even with the right setup, HDR workflows can trip up editors. Here are some common problems and suggestions to fix them:

• HDR Looks Wrong on SDR Displays: If your HDR project looks too dark or flat on a standard screen, it’s because SDR can’t handle HDR’s range. Fix: Make sure you’re previewing on an HDR screen while grading. When exporting, use tone-mapping or a color space transform to generate an SDR (Rec.709) copy. Many NLEs have automatic HDR-to-SDR conversion options or LUTs to help with this.
• Clipped Highlights or Shadows: It’s possible to clip areas even in HDR if you push values too far. Fix: Monitor your waveform/vectorscope in HDR mode. Use smooth adjustments (like S-curve or log tools) to tame hot highlights or crushed blacks. Sometimes dialing down exposure or shifting white point is needed to keep detail in very bright or dark areas.
• Incorrect Color Space or Metadata: An HDR file without proper color primaries or metadata can display incorrectly. Fix: Double-check your export settings to embed the right information. For HDR10, ensure Rec [2020]. primaries and include static metadata (MaxCLL/MaxFALL). For Dolby Vision or HLG, use a proper color-managed workflow or export preset that inserts the needed tags. Using the correct container (usually HEVC/H [265]. for HDR video) also helps preserve HDR data.
• No True HDR Preview: Some editors might find their screen’s not actually going HDR in playback. Fix: On Windows 10/11, enable HDR mode in the display settings and use an HDR-capable output (HDMI 2.0 or DisplayPort) to an HDR monitor/TV. On Mac, use an external HDR display and set the viewing mode appropriately. Also ensure your software’s output is set to HDR (for example, Premiere’s “Enable Display Color Management” should be on). Update your GPU drivers to the latest version, as HDR support can be driver-dependent.
• Client/Team Miscommunication: Clients or team members may not realize a project is HDR. They might ask for changes or playback checks on non-HDR screens. Fix: Communicate clearly about deliverables. Label your files (e.g. “Project_HDR10_master” vs. “Project_SDR_master”) and inform the client which device to use for preview. If feedback comes in on a standard monitor, know that colors and contrast will differ, and adjust your workflow accordingly (perhaps by providing them with the SDR version for review).

VIDIO Shortcut

Some parts of HDR editing can be eased with AI-assisted tools from VIDIO. For example:

• VIDIO Video Upscaler: Uses AI to increase your footage resolution (up to 4K) while preserving fine detail and texture. In an HDR workflow, this helps when you want a higher-resolution master without losing subtle highlights or shadow nuance.
• VIDIO Brighten Tool: Automatically enhances dark scenes by lifting shadows and midtones. This can quickly reveal hidden detail in a night shot or indoor scene before you start your final color grade.
• VIDIO Sharpen Tool: Gently sharpens edges without altering resolution. Applying this to HDR clips can make the image appear crisper and more detailed, complementing the rich contrast of HDR.

These soft AI tools won’t replace your careful color grading, but they can save time on routine steps. By using them where appropriate (for example, upscaling or revealing shadow detail), you can maintain the extra richness of your HDR footage while speeding up the editing process.
