Convert SDR to HDR with AI — AVCLabs Video Enhancer AI

AVCLabs Video Enhancer AI is a great option for beginners who want to convert SDR HDR without dealing with complex color-grading workflows. Its AI-powered SDR-to-HDR feature automatically analyzes video content and expands the dynamic range with a single click, making it easier to enhance brightness, contrast, and visual details.

The AI analyzes the brightness and contrast of each scene to estimate how highlights and shadows should be adjusted for a more HDR-like appearance. The results depend on the quality and content of the original footage.

How to Convert SDR to HDR with AVCLabs Video Enhancer AI?

Step 1: Add your SDR video

Open AVCLabs Video Enhancer AI and import your source video. You can add multiple videos if you want to convert them together.

Step 2: Enable SDR to HDR Feature

Enable SDR to HDR function in the AI feature list. AVCLabs Video Enhancer AI will automatically process the SDR footage to enhance its dynamic range, brightness, contrast, and visual details.

Additionally, you can enable other AI features according to your specific needs.

Step 3: Preview the Result

Click the Preview icon to check the HDR video and compare it with the SDR footage.

Note: For the most accurate evaluation of HDR brightness and color, use an HDR-compatible display with HDR enabled in your system settings. If you're using a standard SDR monitor, you can still preview the video, but the full HDR effect may not be visible.

Step 4: Export the HDR Video

Select an output folder and click "Export" to begin converting.

Convert SDR to HDR with Professional Color Grading — DaVinci Resolve

DaVinci Resolve is an excellent choice if you want to manually convert SDR content to HDR-standard format. It offers users advanced color grading tools and color management systems, allowing them to manually expand the dynamic range, adjust highlights and shadows, and map SDR content to the HDR color space.

Free version user can perform basic inverse tone mapping using HDR color grading tools such as the CST node and HDR color grading panel. The paid version of DaVinci Resolve Studio unlocks more professional features, including support for Dolby Vision and HDR10+ workflows, as well as broader format and encoding compatibility.

How to Convert SDR to HDR in DaVinci Resolve?

Step 1: Import Your SDR Video

Launch DaVinci Resolve, import the SDR material into a new project and place it on the timeline.

Step 2: Configure Color Management

Open Project Settings and navigate to the Color Management tab.

Set Color Science to DaVinci YRGB Color Managed, set Timeline Color Space to Rec.2020, and set Timeline Gamma to either ST.2084 (PQ) or Rec.2100 HLG, depending on your delivery requirements.

Step 3: Grade the Video Using HDR Tools

Go to the Color page and use HDR Wheels, Primary Color Wheels, Contrast and Saturation controls, and Highlight and Shadow adjustments. These tools allow you to expand dynamic range and improve color reproduction for HDR displays.

Step 4: Review and Export

Check the footage on an HDR-capable display if possible. In the Deliver page, select an appropriate codec and configure the output color space and transfer characteristics to match your HDR workflow.

Convert SDR to HDR for Free with FFmpeg

FFmpeg is one of the most powerful free and open-source SDR to HDR converters available at present. It does not rely on fixed presets but allows users to combine various filters and encoding options to complete the entire SDR to HDR conversion process.

Its rich filter library includes zscale for color space and bit depth conversion, as well as libplacebo for advanced tone mapping) and dynamic range expansion. The high flexibility of FFmpeg makes it the preferred solution for high-level users who need to fully master the conversion details.

How to Convert SDR to HDR with FFmpeg?

Step 1: Install FFmpeg

Download FFmpeg from the official website and install the version that includes the libplacebo filter and libx265 encoder. You can run the following command in the terminal to check if the filter is available: ffmpeg -filters.

Search for "libplacebo" in the filter list.

Step 2: Prepare Your SDR Video

Make sure your source video uses a standard SDR color space, such as:

• Rec.709
• BT.1886
• SDR 8-bit footage

Step 3: Convert SDR to HDR

Copy and run the following professional-level commands.

ffmpeg -i input.mp4 \ -vf "libplacebo=colorspace=bt2020nc:color_primaries=bt2020:color_trc=smpte2084:inverse_tonemapping=true" \ -c:v libx265 -pix_fmt yuv420p10le \ -color_primaries bt2020 \ -color_trc smpte2084 \ -colorspace bt2020nc \ -c:a copy output_hdr.mp4

Step 4: Verify and evaluate the HDR output

Inspect output_hdr.mp4 with ffprobe to confirm its color primaries, transfer characteristics, pixel format, and bit depth. Then play it on an HDR-compatible display with HDR enabled to evaluate the brightness and color rendering.
