Report: Converting HDR to SDR Using HandBrake

Date: October 26, 2023 Subject: Technical Workflow and Best Practices for HDR-to-SDR Tone Mapping in HandBrake convert hdr to sdr handbrake

Important notes

• No automatic preview – You may need to test different tone‑mapping curves if the result looks too dark or blown out.
• HLG vs PQ (HDR10) – HandBrake handles both, but PQ (HDR10) may require stronger tone mapping.
• For batch/scripted conversion – Use HandBrakeCLI with --tonemap and --color-primaries options.

Step 6: Audio & Subtitles

• Audio: HDR files usually have lossless audio (TrueHD or DTS-HD MA). Convert this to AAC 5.1 (Bitrate: 640 kbps) or Opus for better quality per bit. Do not passthrough TrueHD unless you have an eARC receiver.
• Subtitles: If your HDR file has "PGS" (Blu-ray subtitles), burn them in or convert them to SRT. PGS often glitches during HDR->SDR conversion.

Why Do You Need to Convert HDR to SDR?

Before we open HandBrake, let's diagnose the problem. Report: Converting HDR to SDR Using HandBrake Date:

The HDR "Washout" Effect: HDR videos use the BT.2020 color space. SDR uses BT.709. When an HDR video is played on an SDR screen without conversion, the player doesn't know how to map the brightness (1000+ nits down to 100 nits). It simply desaturates the image, making everything look grey and foggy. Important notes

Who needs this conversion?

• Plex / Jellyfin users with remote users who have old Rokus or Fire Sticks.
• Editors who need to color grade an HDR clip in software that only supports SDR.
• Archivists who want a universally playable MP4 file.
• Mobile users with Android phones that don't support HDR properly.
