Here is a complete design specification and implementation guide for this feature.
Converting Dolby Vision Profile 7 to Profile 8 is a practical solution for universal playback compatibility. Using dovi_convert for MEL files offers a safe, lossless way to watch your media across all your devices. For FEL files, you must weigh the theoretical loss of color depth against the practicality of guaranteed playback.
| Feature | Profile 7 | Profile 8.1 | |--------|-----------|--------------| | | UHD Blu-ray discs | Streaming, file playback | | Layers | Base + Enhancement + RPU | Single layer (BL+RPU) | | Enhancement layer | Full MEL or FEL | Not present | | Compatibility | Limited players (e.g., Oppo, some TVs) | Wide (Plex, Infuse, VLC, many TVs) | | HDR fallback | HDR10 only | HDR10 or HLG |
Profile 8 is the format used by streaming services like Netflix, Disney+, and Apple TV+. It is popular because it is a "single-track" solution.

# Step 1: Extract HEVC stream from container (MKV/MP4) # We use ffmpeg to extract the raw video to a temporary file cmd_extract = [ "ffmpeg", "-i", self.input_file, "-c:v", "copy", "-f", "hevc", self.temp_hevc, "-y" ] subprocess.run(cmd_extract, check=True)
When converting, you will see references to Profile 8 variants (8.1, 8.2, 8.4).
