+10 and 12-bit encoding 
+===================
+
+## Supported Encoders
+
+The follow encoders support higher than 8-bit.
+
+| Encoder             |
+|---------------------|
+| x264                |
+| x265                |
+| Intel QuickSync     |
+| Apple Video Toolbox |
+
+Please note, you must select a "10-bit" or "12-bit" encoder from the "Video codec" dropdown on the "Video" tab to enable this feature.
+For hardware encoders, the option will only be shown if the system supports it. 
+
+### Limitations
+
+Some filters that ship with HandBrake, do not currently support higher than 8-bit.
+
+When these filters are enabled, HandBrake's pipeline will run at 8-bit rather than 10-bit or 12-bit.
+This applies to the following filters:
+
+- Detelecine
+- Decomb
+- Comb Detect
+- Denoise
+- Nlmeans
+- Chroma Smooth
+- Lapsharp
+- Unsharp
+- Grayscale
