This script is designed as a front-end automation tool for removing Dolby Vision (DV) and HDR10+ metadata from video files (mainly .mkv, .mp4, .hevc, .h265). It wraps together several third-party tools and provides a text-menu interface.

remove_hdr_dv.sh

#!/usr/bin/env bash
# Lightweight HDR metadata remover (Linux)
# Supports: Dolby Vision (dovi_tool), HDR10+ (hdr10plus_tool), HDR10 (ffmpeg hevc_metadata)
# Uses https://github.com/DonaldFaQ/DDVT/blob/Scripts/DDVT_REMOVER.cmd as inspiration

# Requirements:
#   ffmpeg, mkvtoolnix (mkvmerge), gpac (MP4Box), mediainfo
#   dovi_tool, hdr10plus_tool

# Run 
# remove_hdr_dv.sh <file_name>
