The tool will strip the enhancement layer and inject the RPU (dynamic metadata) into the base layer.

This multi-step method is for those who want maximum control, particularly for working with Complex FEL files or for advanced users who want to inspect and potentially edit the RPU data before injection.

You must split the original Profile 7 MKV file into its raw components. Use FFmpeg or MKVToolNix to extract the video track.

ffmpeg -i movie.mkv -map 0:0 -c copy movie.hev

Replace 0:0 with your specific video track ID.

Before converting, you need to check if your file is MEL or FEL. Use dovi_tool to analyze it:

✅ if you need broader device compatibility (Apple TV, Plex on Shield) and your source is MEL or you accept FEL loss. ❌ Avoid if you’re an archivist wanting full FEL preservation – keep original Profile 7 for future 12-bit displays.
