Can someone please explain me what STDL and DTDL stand for
Single Track Dual Layer
Dual Track Dual Layer
Those are terms primarily for DoVi Profile 7, used with UHD BDs.
STDL is used in some formats, e.g., mkv files, where a single HEVC video track can contain the BL+EL+RPU (that is: the 2160p or 1080p Base Layer video substream + the 1080p Enhancement Layer video substream that may carry additional video data + the Reference Picture Unit (RPU) substream that holds the DoVi dynamic metadata).
DTDL is used in some formats, e.g., m2ts files on UHD BD, where the BL video stream is stored in one video track and the EL+RPU substreams are stored in a second EL video track.
MakeMKV can take in DTDL from UHD BD or mkv files, or STDL from mkv files, and output STDL mkv files.
