Lacquer 0.2.1 beta

Lacquer 0.2.1 beta

Fixes from a code review after 0.2.0. If you made a disc with 0.2.0 from a master with separately timed mono tracks, or with a menu of about 18 pages or more as an ISO, make it again with this version.

Audio

• Discrete mono tracks that start at different times now stay in sync. Before, every track took the first track's offset.

Disc menus

• ISO output works with large menus, 100+ chapters and many scene pages. Before, it failed after the encode. Lacquer now checks the layout right after rendering the menu, before it encodes.
• Very long titles and subtitles end in an ellipsis instead of running off the frame or over the buttons.
• Menu backgrounds and chapter thumbnails from interlaced masters are deinterlaced, so there's no combing.
• The designer's busy indicator no longer sticks when you switch pages quickly.

Queue

• Two encodes of same-named masters into one folder can no longer pick the same output or delete each other's disc.
• Very long file names are shortened to fit, and the log is always written.
• Rows of running and finished jobs show the format the disc was actually made with.
• Adding the same file twice at the same moment makes one job.
• Quitting during an encode never waits more than ten seconds.

Command line (--headless --iso-from)

• An image written inside its own source folder no longer copies itself.
• A missing source folder is refused instead of producing a blank image.
• Long and non-Latin file names are stored correctly, and folders with many files work.
• --menu-loop rejects values that aren't finite or are out of range.

Known limits

• libbluray, the library VLC uses, has checked the menus and discs, but no hardware player has played them yet. Burn one disc and test it on your player before a duplication run.
• In VLC, a menu button pressed while playback is paused waits until you resume, and any presses you made while it was paused are ignored. Press Play again after resuming.
• No E-AC-3, TrueHD or DTS audio, because those formats need licences.
• No Intel build.

Files

• Lacquer-0.2.1-arm64.dmg: the app, signed and notarized.
• Lacquer-0.2.1-source.tar.gz: corresponding source for the app and the bundled FFmpeg, x264, zimg and tsMuxeR, with the build scripts.
• SHA256SUMS

Lacquer 0.2.0 beta

Lacquer 0.2.0 beta

Lacquer turns a finished film master into a Blu-ray: a BDMV folder, a UDF 2.50 disc image ready for a duplicator, or an M2TS for Toast. You can add an on-screen menu too. This is the first public release. It's free and open source under GPL-3.0, and runs on Apple Silicon Macs with macOS 13 or later.

What it does

• Picks the Blu-ray format that keeps every frame of your master. 25 and 29.97 fps go on the disc as 1080i carrying whole frames, and the queue warns you if a format you choose would drop or repeat frames.
• Handles the audio layouts editors export. Lacquer uses a 5.1 track as is and combines six separate mono tracks into 5.1, in SMPTE or film order. Audio is AC-3.
• Sets the bitrate to fill BD-25 or BD-50, and refuses a film that can't fit before encoding starts.
• Tonemaps HDR masters, converts SD color, and deinterlaces before scaling.
• Turns .srt files, including Windows-encoded ones, into subtitles viewers can switch on and off. Chapter stops land on exact frames.
• Adds disc menus in three styles: a background frame or poster, Play, scene pages with named chapters, and subtitles on and off. Navigation is real HDMV, so First Play and Top Menu work.
• Checks free space, the output folder and disc fit before encoding. Stop and Quit clean up after themselves, and every disc gets a log.

Known limits

• libbluray, the library VLC uses, has checked the menus and discs, but no hardware player has played them yet. Burn one disc and test it on your player before a duplication run.
• In VLC, a menu button pressed while playback is paused waits until you resume, and any presses you made while it was paused are ignored. Press Play again after resuming. Hardware players don't pause on menus.
• No E-AC-3, TrueHD or DTS audio, because those formats need licences.
• No Intel build.
