Converting Dolby Vision Profile 7 (typically found on 4K Blu-rays) to Profile 8.1 (widely compatible with streaming devices like the Apple TV or Nvidia Shield) is primarily done by stripping the Enhancement Layer (EL) and injecting the Dynamic Metadata (RPU) directly into the Base Layer (BL). This process does not require re-encoding, so there is no loss in video quality. Recommended Tools
- Dolby Vision is a licensed technology. Include licensing checks/warnings; do not claim official Dolby certification unless obtained.
- Ensure key-file handling for any signed metadata is secure.
If RPU is embedded in SEI and you need external RPU:
dovi_tool inject-rpu -i BL.hevc --rpu-in rpu_8.1.bin -o output_P8.hevc
Remux:
Use a tool like MKVToolNix or ffmpeg to take the newly created BL_RPU.hevc file and combine it with the original audio and subtitle tracks. Key Considerations
3. Technical Implementation Logic
: Profile 8.1 includes an HDR10 base layer, ensuring that if a display doesn't support Dolby Vision, the video still plays in high-quality standard HDR. Latest Tools and Methods (2024–2025)
