+HDR10 encoding 
+===================
+
+## Supported Encoders
+
+All encoders that support 10-bit encoding are also capable of HDR10 encoding. The follow encoders support higher than 8-bit.
+
+| Encoder             |
+|---------------------|
+| x264                |
+| x265                |
+| Intel QuickSync     |
+| Apple Video Toolbox |
+
+HandBrake will automatically passthru mastering display metadata and content light metadata from the source video to to final encode. For x265 encodings, HandBrake will also set the hdr-opt flag for you.
+
+### Limitations
+
+HandBrake will only handle HDR10 metadata. HDR10+ and Dolby Vision is currently not supported.
