Restore Dolby Vision

FFmpeg Builder: Restore Dolby Vision

Re-injects Dolby Vision RPU back into an encoded HEVC stream for maximum compatibility. Profile 8.x sources are left untouched. Profile 5 and 7 sources are converted to a more compatible format so the output works on a wider range of devices.

Remove HDR10+​

Removes HDR10+ metadata from the output. This fixes black screen issues on some devices (e.g., FireStick).

Use Crop Fix​

Applies dovi_tool --crop to sanitize bad crop metadata. Only enable this if you know your source has incorrect crop information.

Required Tools​

Docker​

Install the following DockerMods:

  • dovi_tool — extracts and injects Dolby Vision RPU metadata
  • MKVToolNix — provides mkvmerge, mkvextract, and mkvinfo

Other Systems​

Manually install the required tools and add them to your Variables page in FileFlows:

  • dovi_tool
  • mkvmerge
  • mkvextract
  • mkvinfo
note

Each variable name should match the tool name exactly (e.g., create a variable named dovi_tool pointing to the executable).

Outputs​

  1. Dolby Vision restored successfully.
  2. No fix required.
