Every title, playlist, clip, duration, chapter mark, stream and AACS state, read through libbluray.
Blu-ray ripping and authoring
Your discs, kept like they matter.
Rip, author, verify and burn Blu-ray discs with native tooling, on macOS, Linux and Windows. Native AACS key recovery, UDF 2.50 images, authored BD-J menus, DVD-Video and 1:1 clones. No MakeMKV, no subscription.

What it does
One workshop for the whole disc.
Inspect first, rip losslessly, author something new, then check it before it touches a burner.
No MakeMKV required
Recover AACS1 volume and disc keys, and derive AACS2 unit keys, from the disc and the drive.
Lossless remux
H.264, HEVC, VC-1, MPEG-2 with AC-3, E-AC-3, DTS, TrueHD, FLAC and PGS subtitles into MKV or MP4.
x264, x265, VideoToolbox
Software or hardware encoding, 8-bit or 10-bit, with sensible default track selection.
BDMV and ISOs
One title or many, a BDMV folder or a UDF 2.50 image: newfs_udf on macOS, a portable writer elsewhere.
A real BD-J menu
An authored 1080p title menu, one row per title, with a background, arrow keys, digits and mouse.
VIDEO_TS too
List and rip DVD titles through ffmpeg's dvdvideo demuxer, keeping MPEG-2 and AC-3 or DTS.
Episode splitting
Split a disc into per-episode files with SxxExx names, OP/ED detection and TMDB metadata.
1:1 clone
Clone the encrypted structure bit for bit, or export a decrypted ISO or folder when you want plain files.
Verify before you burn
Walk the navigation, every PlayPL, every playlist and every clip, plus the BDJO, JAR and menu rows.
Native and guarded
hdiutil burn by default, growisofs when you name a device. Dry run first, confirmation required.
MCP and a real CLI
Every capability is a command and an MCP tool, so an assistant can drive the whole workflow.
The loop
Disc in, keepsake out.
Nothing is written until you say so. Every destructive step has a dry run, a confirmation or both.
Know what is on it
Insert the disc, read the title map, pick the main feature and look at the streams before a single byte moves.
Rip or build
Remux losslessly, encode for size, or take finished files and author a new disc with a menu and chapter marks.
Verify, then burn
Run the tree check, mount the ISO to read it back, and only then hand it to the writer after confirmation.
Authored menu
A menu that is actually there.
One generic Xlet reads the disc's own title list at runtime. No per-disc Java compilation.
Downloads
Take a build.
Builds are mirrored to GoFile and file.kiwi. Links are refreshed weekly, because free tiers expire.
macOS (Apple Silicon)
Keepsake-Atelier-0.1.0-arm64.dmg
The DMG is not notarized. Open it once with right-click then Open, or run
xattr -dr com.apple.quarantine "/Applications/Keepsake Atelier.app".
The DMG bundles libbluray libaacs libbdplus; the CLI tarballs need
brew install libbluray libaacs libbdplus.
Linux ships a CLI, an AppImage and a deb; Windows ships a CLI zip and an
NSIS installer. Both desktop builds are previews; see the platform matrix in the docs.
Read the install guide.
Guides
Start where you are.
Short, task-shaped pages. Every one ends with the exact commands and the checks to run.
Install and connect a drive
Gatekeeper, the first launch, and what doctor should say.
Rip a movie
Pick the main title, choose tracks, remux or encode, and find the file.
Author a disc
One title or a season, a folder or an ISO, with chapters kept.
Give it a menu
Turn on the BD-J menu, choose a background, and verify the rows.
Keys and AACS
KEYDB, native recovery, LibreDrive limits and what to do when it fails.
Burn and verify
Size query, dry run, the real write, and the read-back check.
DVD-Video
List the titles and copy MPEG-2 with AC-3 or DTS.
TV and anime
Episode split, naming, openings and endings, and TMDB.
Drive it with an assistant
Turn on the MCP server and hand the workflow to Claude or Cursor.
Support
Keep the workshop open.

Questions
The short answers.
Does it need MakeMKV?
No. Native AACS key recovery reads the volume ID from the drive and derives the key from the disc's MKB. MakeMKV dumps are supported as a fallback but are not required.
Why does native key recovery fail on my drive?
The volume ID needs a LibreDrive vendor read. Stock firmware on many drives does not provide it. libaacs with a KEYDB entry still decrypts, and the app says which path it used.
Are the authored menus verified?
The BDJO, the JAR and the menu rows are checked, and the Xlet is run in a real JVM harness. Hardware playback is still untested, so menus are opt-in with author --menu.
Can it burn?
Yes. macOS uses hdiutil burn, Linux uses growisofs, and Windows uses the built-in IMAPI2 stack. Dry run is the default and a write needs an explicit confirmation. A blank BD-RE or BD-R is required. The Windows write path is implemented but has not been run on a physical writer yet.
Where are keys and settings stored?
Under ~/Library/Application Support/keepsake-atelier. The KEYDB file stays local and is never uploaded.
Is there a Windows or Linux build?
Yes. Linux ships a tested CLI plus AppImage and deb builds; Windows ships a CLI zip and an NSIS installer. Both desktop builds are previews, and drive discovery, ripping and authoring work there. Burning and native AACS recovery remain macOS features.
