) from the original file and inject it into a single-layer HEVC file, discarding the enhancement layer ( ) in the process Method 1: Using Automated Scripts (Recommended)

A crucial pre-conversion step is determining what type of Enhancement Layer your source file contains. This distinction has a direct impact on whether the conversion can be considered "lossless" or not.

Because there is no secondary Enhancement Layer to decode, nearly every modern streaming box can read the RPU and apply proper Dolby Vision tone-mapping seamlessly. Important Pre-Conversion Checks: MEL vs. FEL

: A user-friendly macOS application and Linux script that handles demuxing, RPU extraction, and remuxing into a new MKV file.

Use ffmpeg to pipe the HEVC stream into dovi_tool , which discards the enhancement layer and converts the RPU to Profile 8.1.

This comprehensive guide breaks down the core technical differences between these formats and provides clear, step-by-step methods to execute the conversion safely without losing video quality. Why Convert Profile 7 to Profile 8?

Ensure your audio is compatible (AAC or E-AC3 for MP4).

: A dedicated macOS app that offers a drag-and-drop interface for converting P7 files specifically for users of the Infuse video player on Apple TV.

# Step 4: Inject the new RPU back into the video stream # We take the original base layer and inject the converted RPU cmd_inject = ["dovi_tool", "inject-rpu", "-i", self.temp_hevc, "-o", "final_p8.hevc", "-r", "converted_rpu.bin"] subprocess.run(cmd_inject, check=True)

Here is a complete design specification and implementation guide for this feature.
