Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson and Adam Klotblixt.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669.

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).
• Fix incorrect parsing and creation of IDs for PNG subtitles (#1965).

Other fixes

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson and Adam Klotblixt.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• New “Combiner&rduo; tool to combine multiple DCPs into one (#1245).
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).
• Fix incorrect parsing and creation of IDs for PNG subtitles (#1965).

Other fixes

• Fix periods of black between trimmed content in the preview.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson and Adam Klotblixt.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• New “Combiner&rduo; tool to combine multiple DCPs into one (#1245).
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).
• Fix incorrect parsing and creation of IDs for PNG subtitles (#1965).

Other fixes

• Fix periods of black between trimmed content in the preview.

• Updated sv_SE translation from Mattias Mattsson.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).

Other fixes

• Fix periods of black between trimmed content in the preview.

Version 2.15.147

Known problems in this version

• Encode server tray icon is hard to see in macOS dark mode (#1986).
• leqm calculations could be wrong for stereo sources (#1991).

Operating system support

From this version onwards, DCP-o-matic no longer supports:

• macOS versions 10.9 (Mavericks) or earlier.
• Windows XP

If you need to use one of these operating systems please use the latest released 2.14.x version of DCP-o-matic.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).
• Checksum network encode requests and replies to protect against network corruption (#1381).
• Allow more complete control over the libdcp/DCP-o-matic metadata written to various places.
• Add Bob Weaver Deinterlacing Filter (bwdif).
• Add a new “Add DKDM” dialogue (#1637).
• Basic handling of overlapping video (#1848).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).
• Clicking on the audio graph jumps to that position in the film (#1507).
• Put the timecode next to the rewind-to-0 button to help avoid mouse-slips (#1234).
• Allow > 0dB gain per channel in the audio matrix (#1720).
• Add some new keyboard shortcuts for moving around on the timeline.
• Remove the ISDCF metadata dialogue box (#1929); all metadata is now set in the “Metadata” dialogue.

• Fix crash on dragging timeline content in some cases.
• Potential fix for assertion failures in audio buffers during analysis in some cases (#1568).

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).
• Fix incorrect parsing and creation of IDs for PNG subtitles (#1965).

Other fixes

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).

Version 2.15.140

Operating system support

From this version onwards, DCP-o-matic no longer supports:

• macOS versions 10.9 (Mavericks) or earlier.
• Windows XP

If you need to use one of these operating systems please use the latest released 2.14.x version of DCP-o-matic.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).
• Checksum network encode requests and replies to protect against network corruption (#1381).
• Allow more complete control over the libdcp/DCP-o-matic metadata written to various places.
• Add Bob Weaver Deinterlacing Filter (bwdif).
• Add a new “Add DKDM” dialogue (#1637).
• Basic handling of overlapping video (#1848).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).
• Clicking on the audio graph jumps to that position in the film (#1507).
• Put the timecode next to the rewind-to-0 button to help avoid mouse-slips (#1234).
• Allow > 0dB gain per channel in the audio matrix (#1720).
• Add some new keyboard shortcuts for moving around on the timeline.
• Remove the ISDCF metadata dialogue box (#1929); all metadata is now set in the “Metadata” dialogue.

• Hopefully fix incorrect bitmapped subtitle colours.
• Fix reel setup when the last reel is less than 1 second long.
• Use XX as an audio language when there is no specified audio language (#1939).
• Fix incorrect parsing and creation of IDs for PNG subtitles (#1965).

Other fixes

Version 2.15.137

Operating system support

From this version onwards, DCP-o-matic no longer supports:

• macOS versions 10.9 (Mavericks) or earlier.
• Windows XP

If you need to use one of these operating systems please use the latest released 2.14.x version of DCP-o-matic.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.
• Updated sv_SE translation from Mattias Mattsson.

New features and major changes

• New “Disk Writer” tool to create DCP drives in EXT2 format from any platform.
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player, and accompanying dcpomatic2_verify command-line tool.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Add builds for ARM / Apple Silicon (M1) processors.
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Add an output audio matrix (#1482).
• Support download of certificates from Qube (#1460).
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12) (#1498).
• Checksum network encode requests and replies to protect against network corruption (#1381).
• Allow more complete control over the libdcp/DCP-o-matic metadata written to various places.
• Add Bob Weaver Deinterlacing Filter (bwdif).
• Add a new “Add DKDM” dialogue (#1637).
• Basic handling of overlapping video (#1848).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).
• Clicking on the audio graph jumps to that position in the film (#1507).
• Put the timecode next to the rewind-to-0 button to help avoid mouse-slips (#1234).
• Allow > 0dB gain per channel in the audio matrix (#1720).
• Add some new keyboard shortcuts for moving around on the timeline.

Version 2.15.134

Operating system support

From this version onwards, DCP-o-matic no longer supports:

• macOS versions 10.9 (Mavericks) or earlier.
• Windows XP

If you need to use one of these operating systems please use the latest released 2.14.x version of DCP-o-matic.

Translations

• Updated nl_NL translation from Rob van Nieuwkerk.
• Updated cs_CZ translation from Tomáš Begeni.

New features and major changes

• Disk Writer tool to create DCP drives in EXT2 format from any platform.
• Option to ignore video parts of files (#1355 and others).
• Option to set video range (JPEG/MPEG) (#1509).
• Support for CPL metadata and markers.
• Improved DCP verification in the player.
• Compliance with most (not yet all, but it's coming) of the SMPTE DCP Bv2.1 Application Profile.
• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Support download of certificates from Qube (#1460).
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12). Fixes #1498.
• Checksum network encode requests and replies to protect against network corruption (#1381).
• Allow more complete control over the libdcp/DCP-o-matic metadata written to various places.
• Add an output audio matrix (#1482).
• Add Bob Weaver Deinterlacing Filter (bwdif).
• Add a new “Add DKDM” dialogue (#1637).
• Basic handling of overlapping video (#1848).
• Add builds for ARM / Apple Silicon (M1) processors.

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).
• Clicking on the audio graph jumps to that position in the film (#1507).
• Put the timecode next to the rewind-to-0 button to help avoid mouse-slips (#1234).
• Allow > 0dB gain per channel in the audio matrix (#1720).
• Add some new keyboard shortcuts for moving around on the timeline.

Bug fixes

• Possible fix for various causes of audio/video sync problems in DCPs.
• Fix missing burnt subtitles in some rare cases (#1581).
• Fix periods of black between trimmed content in the preview.
• Fix incorrect video range on exported files.
• Fix crash with some color attributes in Subrip files.
• Fix crash on dragging timeline content in some cases.

• New tool to combine DCPs (#1245).
• New playlist (SPL) editor for the player.
• Support download of certificates from Qube (#1460).
• Basic subtitle export feature.
• Calculate LEQ(m) when analysing audio.
• Allow export with one audio stream per channel.
• Allow specification of audio forensic marking (in KDMs) for some channels only. Default to enabling forensic marking for video and audio (up to and including channel 12). Fixes #1498.
• Checksum network encode requests and replies to protect against network corruption (#1381).
• Allow more complete control over the libdcp/DCP-o-matic metadata written to various places.
• Add an output audio matrix (#1482).

• Add a new “Add DKDM” dialogue (#1637).
• Add builds for ARM / Apple Silicon (M1) processors.

Workflow improvements

• Re-work scaling following excellent insights by Carsten Kurz, described on #1669. Now the scaling of video content is guessed based on its aspect ratio (taking into account pixel aspect ratio) and there is a "custom" option for overriding incorrectly-marked-up content or content which actually needs its shape to be changed.
• Add a new "Advanced settings" dialog for content, accessible from the right-click menu. Move the "use video" checkbox into here, as it feels like excessive clutter to have it in the main video panel.
• Add subtitle analysis so that the outline of all subtitles in a piece of content can be overlaid onto the preview (#1233).
• Add playhead line to timeline (#1563).
• Add option to set project properties from a DCP loaded as content (#1688).
• Avoid unnecessary re-writes of video assets if they are staying the same (#1638).
• Clicking on the audio graph jumps to that position in the film (#1507).
• Put the timecode next to the rewind-to-0 button to help avoid mouse-slips (#1234).
• Allow > 0dB gain per channel in the audio matrix (#1720).
• Add some new keyboard shortcuts for moving around on the timeline.

• Prevent reference/reel setting controls getting stuck when referenced content is moved with reel mode 'single' enabled (#1645).
• Set fade in/out using content frame rate rather than DCP rate (#1642).
• Try to ignore exceptions thrown from boost::filesystem::is_symlink (#1662).
• dcpomatic_create now responds to --version on stdout, not stderr (#1686).
• Fix layout bug where the stuff in the content panel would be completely hidden in some cases (seen on Linux only, I think).

• Add export button for DKDMs (#1510).
• Better progress reporting during DCP validation (#1812).
