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.
