Why You Need HDR Video?
SDR vs HDR, which is better? Traditional SDR video often produces lackluster images with poor detail in highlights and shadows.
In contrast, HDR video expands the brightness range of images, displaying a wider color gamut and higher bit depth, thereby presenting a more realistic, vivid and delicate picture.

- Nature PhotographyHDR technology in photography presents nature landscapes with richer, more vivid colors, resulting in more real and comfortable images.
- Special Effects ScenesHDR technology provides a broader color space and high-precision image quality, making special scenes more realistic and detailed.
- Night PhotographyHDR technology captures a wider range of details and brightness in high-contrast night scenes, avoiding the information loss of images caused by overexposure or underexposure.
Upscale video to Dolby Vision to maximize video quality
Dolby Vision outperforms other HDR standards by delivering unparalleled video quality. UniFab is able to generate dynamic metadata up to Dolby Vision standard, thereby upscaling SDR or HDR 10 videos to superior Dolby Vision quality.
The Dolby-standard dynamic metadata can also fine-tune parameters like brightness and color saturation on a frame-by-frame basis and reveal more details tailored to the content. The enhanced Dolby Vision video will ensure you an immersive viewing experience with richer colors, deeper blacks, and brighter highlights.
Note: Dolby Vision video is only played on devices that support Dolby Vision standard.

Upscale SDR to HDR10 for optimal compatibility with your HDR device
HDR10 is a more common HDR standard known for its broad device compatibility, although its video quality is not as superior as Dolby Vision. UniFab HDR Upscaler AI offers two HDR10 video modes: Universal and Cinema, designed for different viewing scenarios. You are free to select the mode that best suits your space.
DCI-P3 and Rec.2020 color spaces are open to choose based on different devices. By opting for a suitable color space, you stand to enjoy more vivid, bright and realistic images while also reducing visual fatigue and discomfort.
Note: HDR10 video is only played on devices that support HDR10 standard.

Two Video Modes
Universal Mode offers slightly increased brightness, allowing you to perceive video details even in spaces with less-than-ideal light control.
Cinema Mode features a lower brightness than Universal Mode. However, it boasts an expanded brightness range that shows more pronounced light-dark contrasts and realistic visuals.

Two Color Spaces
DCI-P3 is a widely used color space that provides excellent display effects. It is compatible with most HDR devices.
Rec.2020 is a color space that supports a wider gamut than DCI-P3. However, you'll need newer display devices to fully experience the enhanced display effect of Rec.2020.

* Converting HDR10 to Dolby Vision primarily relies on CPU processing power rather than GPU capability.
* Using AMD or Intel graphics chips in HDR upscaling shows a slower speed than NVIDIA graphics cards of similar level because they do not support TensorRT technology.
