Status of the support for Dolby Vision

This page details the status of the support for Dolby Vision in the upcoming MKVToolNix v81.0 as of 2023-11-29.

Dolby Vision support is considered to be complete as of v81. This means that all features that were targeted initially have been implemented (potential bugs notwithstanding; those will be fixed, of course). Further work might extend Dolby Vision to other codecs.

Codecs

Dolby Vision is currently only supported in combination with HEVC/H.265 and AV1, not with AVC/H.264.

  5. neither Matroska nor MP4 store both layers in different tracks (see "Dolby Vision Streams Within the ISO Base Media File Format Version 2.2"), or rather: MP4 only does so in older files, and I won't support those ↩︎

  6. implemented in release 81.0 in revision 473081e2e88aaf7411343866d667133e68f86fa9; see #3127 for details ↩︎

  7. unsupported & won't be supported in the future either ↩︎

  8. see #3126 for caveats ↩︎

  9. as Matroska will only store both layers in the same track, splitting them up into multiple tracks won't be supported ↩︎
