Convert Dolby Vision Profile 7 To Profile 8 New -

Assuming you have an MKV file containing a Profile 7 Dolby Vision stream (identifiable via mediainfo as Dolby Vision, Version 1.0, Profile 7):

mkvmerge --identify your_movie.mkv

Note the track ID of the video stream (e.g., 0). Then extract:

mkvextract your_movie.mkv tracks 0:video.hevc

The gold standard remains dovi_tool (by quietvoid) plus mkvmerge and ffmpeg. convert dolby vision profile 7 to profile 8 new

Basic workflow (lossless):

For full 12‑bit P8.4 (experimental, limited player support): Assuming you have an MKV file containing a

dovi_tool -m 3 convert

Only a few players (e.g., CoreELEC on AM6B+, certain LG TVs with custom firmware) support it.

  • Profile 7 (typical consumer streaming deliverable):
  • Profile 8 (often called Profile 8.1/8.2 depending on variant):
  • Compliance: Dolby Vision has strict spec requirements; improper conversion can break playback or fail delivery QC.

    • Open the file in MKVToolNix GUI or use the command: Note the track ID of the video stream (e

    mkvmerge -i movie.mkv

    Look for a video track with "Dolby Vision" listed. You need to note the track ID (usually 0).

    This is the core of the new workflow. We tell dovi_tool to convert the RPU metadata from Profile 7 to Profile 8.1 (HDR10 compatible).

    dovi_tool -i movie.hev convert -f 8.1 -o movie_converted.hev

    What this does:

    Note: For LG TVs, use 8.1. For Apple devices, 8.1 is also standard. For Samsung (HDR10+ hybrid), use 8.4.
