For a MEL file, the conversion is straightforward. Run the following command:
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

Thanks to the incredible updates to dovi_tool (by quietvoid) and mkvtoolnix , we can now convert Profile 7 to Profile 8 without losing the dynamic metadata, and without complex EL merging. The new method simply rewrites the RPU (Reference Processing Unit) to Profile 8 compatibility while keeping the video stream intact.
Creating a "Convert Dolby Vision Profile 7 to Profile 8" feature requires a specific technical approach because Profile 7 (typically found on discs) contains a secondary "RPU (Reference Processing Unit) track" that most TVs and streaming devices cannot read. Profile 8 "bakes" this HDR data into the video stream, making it compatible with standard Dolby Vision TVs.

Dolby Vision profiles define how video data and its accompanying dynamic metadata are packaged. Each profile is tailored for specific use cases, from broadcast to streaming and physical media. For a MEL file, the conversion is straightforward
The output should show , confirming a successful conversion.
By converting, you are effectively creating a "single-layer" version of your video file that uses the same RPU metadata as the original. This is exactly what streaming services do, guaranteeing smooth playback on all modern hardware.

Media enthusiasts frequently encounter playback issues with UHD Blu-ray rips. This problem stems from Dolby Vision Profile 7. Most streaming devices and smart TVs cannot play Profile 7 natively. Converting Profile 7 to Profile 8 solves this compatibility issue. This guide explains how to convert your video files while preserving high dynamic range quality. Understanding Dolby Vision Profiles
The shift toward Dolby Vision (DoVi) Profile 8.1 is a practical response to the compatibility limitations of Profile 7, which was originally designed for physical Ultra HD Blu-ray discs. While Profile 7 utilizes a "dual-layer" system (Base Layer + Enhancement Layer) that many modern streaming players cannot fully decode, Profile 8.1 offers a "single-layer" alternative that preserves dynamic metadata while ensuring a stable HDR10 fallback. Why Convert Profile 7 to Profile 8.1? Broad Compatibility : Most digital media players, including the Apple TV 4K smart TV Plex apps
: Uses a Dual Layer (DL) consisting of a Base Layer (BL), an Enhancement Layer (EL), and Reference Processing Unit (RPU) metadata.
