7 Effective Ways to Convert HDR to SDR on iPhone/Mac/More [Full Guide]

Part 1. What Does HDR and SDR Mean & Why Convert HDR to SDR

➡️ What Does HDR and SDR Stand For

Definition of HDR & SDR
HDR stands for High Dynamic Range, and SDR stands for Standard Dynamic Range. These are two types of video and image display technologies that handle contrast, brightness, and color differently.

• HDR refers to High Dynamic Range, which is video with luminance range beyond the standards, darker blacks, brighter highlights, and a broader color gamut. It's designed to deliver a more lifelike viewing experience, especially on compatible HDR-capable displays.
• SDR refers to Standard Dynamic Range, which is the type of format that is utilized by most displays as well as online platforms. is the traditional standard used in most displays and broadcast systems for decades. It uses a more limited range of brightness and colors.

What does HDR to SDR mean
It is the process of transforming high dynamic range video into standard dynamic range, so the footage can be viewed on devices that do not support Rec 709 or sRGB color palettes. This often aims to ensure compatibility with devices or platforms that do not support HDR playback.

⚖️️ Why Choose to Convert HDR Video to SDR: SDR vs HDR

• On SDR monitors, HDR would be washed out or too bright. SDR is more predictable across various devices
• Many older TVs, monitors, and mobile devices only support SDR.
• Some editing platforms or workflows may not fully support HDR color grading or rendering. Editing or sharing a 4K SDR vs HDR comparison indicates SDR is more universal.
• SDR content generally requires less bandwidth and storage, making it more efficient for streaming and archiving.
• The conversion due to the difference between HDR and SDR is useful because it enables you to create clear, consistent-looking videos on older devices.

☺️Popular Techniques for HDR Video to SDR Conversion

• Tone mapping compresses dynamic ranges so it fits SDR displays, maintaining detail in both shadows and highlights.
• The conversion of the color space down-scales Rec 2020/PQ/HLG to Rec 709, ensuring colors display correctly on SDR devices.
• Banding is avoided with Gamma curve adjusting (such as PQ vs Rec. 709) and reduction of bit depth.
• HDR content contains metadata for brightness and color calibration. Stripping metadata for SDR playback.

Part 2. How to Convert HDR to SDR on iPhone/Mac/Other Devices (Quick Ways)

Regardless of the device you are on, you can use one of these methods to get your videos to play on unsupported devices with ease.

Method 1. Use HandBrake to Change HDR to SDR [Free & Beginner-Friendly]

HandBrake is a free, open-source video transcoder that supports HDR to SDR tone mapping. While HandBrake does not natively support automatic HDR to SDR conversion, you can manually adjust the color space. It's perfect for beginners who want a quick and free method to process videos.

• Install and open the Hadnbrake app. click “File” under “Source Selection”, or drag and drop your HDR video (e.g., MP4, MOV) into the interface.

  

• On the new screen, find the “Preset” tab and choose "Fast 1080p30" or others for quick results.

• Under Preset, you can find a menu bar. Switch to “Filter” there and set the "Colorspace" filter to "BT.709" (SDR uses this color space).

• Once set, tap on the top green “Start Encode” button to kick off the HDR conversion to SDR video.

  

Tips:

HandBrake’s tone-mapping is basic and may result in overblown highlights or washed-out colors. Adjust Quality (lower CRF value, e.g., 18–22) for better results.

Method 2. Convert HDR to SDR with FFmpeg [Advanced Users]

FFmpeg is an efficient command-line tool. It allows an advanced user to customize the 4K HDR to 1080p SDR process with tone mapping, color transformation, and encoding possibilities.

• Download FFmpeg and extract its contents to a new folder.

• Place your HDR video in a folder (e.g., F:\Videos) and rename it to HDR .mp 4 for simplicity.

• On Windows, create a text document named ffmpeg .bat in the FFmpeg bin folder.

  

• Right-click on the BAT file, choose “Edit” from the drop-down, and paste the command below:

  ffmpeg -i HDR.mp4 -vf zscale=1920:-1:f=spline36:t=linear:npl=291,tonemap+reinhard:param=0.6:desat=0,zscale=t=709:p=709:m=709,format=yuv420p -c:v libx264 -crf 18 -c:a copy SDR.mp4

• Save the typed content and exit the .bat file. Afterward, double-click on it and the FFmpeg will run those command and operate the conversion process.

• When it finished, a new video file named SDR.mp4 has been created.

• Click "Convert" and when it is converted, click "Download" to save the file offline.

  

Method 4. Encode Selected HDR Video to SDR

This method works on macOS, and it requires minimal effort and no complex software. The process is very simple and involves no complicated steps, as elaborated below:

• Right-click on your video file and select "Encode Selected Video Files”.

• In the Encode Media pop-up, choose "H.264 1080p" and click "Continue" to convert HDR to SDR.

• Now, macOS will encode your video, and shortly you will have a new SDR video file.

  

Part 3. Convert HDR to SDR in Popular Video Editing Software (Advanced Ways)

If you have professional video editing software and experience with complicated processes, then you can use the following advanced methods.

People Also Ask about HDR to SDR Conversion

Q1: Is SDR better than HDR?

SDR does not necessarily make it better. HDR provides greater detail and lightness. But on devices or platforms that cannot support HDR, SDR provides a well-known and compatible playout.

Q2: How to make HDR look like SDR?

You need to convert HDR to SDR to make it work on your devices. Then tone mapping can be accomplished with HandBrake, Premiere Pro, or DaVinci Resolve to adjust dynamic range and color space.

Q3: What does HDR -> SDR mean?

It refers to converting high dynamic range video to standard dynamic range to ensure it is properly played on SDR systems. It mostly involves tone mapping and conversion of color gamut.

Q4: How to fix the issue of "adding an HDR clip to an SDR project and it is too bright" in Final Cut Pro?

Go to an SDR timeline and tweak the exposure/color by hand- or use the FCP HDR export settings that scale down automatically from HDR video to SDR video.

Q5: How to convert SDR to HDR?

Expand the dynamic range with reverse tone mapping or grading tools. However, you must master the image on an HDR-capable display and output formats to produce true HDR.
