BatchForge+ is licensed, not sold. Non-exclusive, non-transferable. Commercial use in creative and production workflows is permitted. Resale and redistribution are not permitted. Full EULA: EULA - BatchForge+ v1.1.0 (PDF version on request).

Provided "as is." No guarantee of compatibility with unsupported macOS versions or third-party applications. Liability is limited to the amount paid.

Purchases include 12 months of updates from date of purchase. Minor updates (bug fixes, codec compatibility, UI improvements) are included. Major version upgrades may require a new license. Future codec additions are goals, not guarantees.

Please verify macOS version compatibility before purchase. Refunds may be considered for non-delivery, activation failure, or non-functional behavior in a clearly documented and supported environment. Not granted for unsupported systems, third-party incompatibilities, or change of mind. Mandatory consumer rights apply where required by law. EU statutory withdrawal: for digital products with immediate download access, the right of withdrawal expires upon download initiation, in accordance with Art. 16 m of the EU Consumer Rights Directive (§ 356 V BGB). By initiating the download, you explicitly waive the 14-day withdrawal period.

Standard support covers installation guidance, setup clarification, basic troubleshooting, and clarification of documented behavior. It does not cover custom pipeline consulting, feature development, or debugging third-party systems.

When reporting an issue, include your macOS version, hardware (Apple Silicon / Intel), the application or host involved, and exact reproduction steps.

No public trial or demo build is currently available. Before purchase, review the compatibility notes, feature documentation, and Early Access terms. Pre-purchase questions can be directed to [email protected].

Product: b3LAB BatchForge+ · Publisher: b3LAB

This notice lists third-party software, SDKs, frameworks, APIs, trademarks, and optional external runtime dependencies that may be used by this product. BatchForge+ is an independent b3LAB product. References to third-party names, frameworks, SDKs, trademarks, and file formats are for compatibility, attribution, and interoperability purposes only. No sponsorship, approval, endorsement, certification, or affiliation is implied unless explicitly stated in a signed agreement.

This notice is provided for distribution compliance and transparency. It is not legal advice.

Apple System Frameworks and macOS APIs

Components may include: AVFoundation, CoreMedia, CoreVideo, CoreAudio, VideoToolbox, Metal, IOSurface, CoreImage, AppKit, SwiftUI, System Extensions, CMIO Camera Extension APIs, and related Apple platform APIs.
Provider: Apple Inc. License / terms: governed by the applicable Apple Developer Program License Agreement, Apple SDK Agreement, macOS software terms, signing/notarization requirements, and related Apple documentation.

Apple, macOS, Metal, AVFoundation, CoreMedia, CoreVideo, CoreAudio, VideoToolbox, AppKit, SwiftUI, and related names are trademarks of Apple Inc. BatchForge+ is independent and is not endorsed by Apple. The hardware-accelerated H.264 / HEVC / ProRes encoders are part of macOS and licensed by Apple.

FFmpeg / ffprobe

Component: FFmpeg and ffprobe command-line tools — bundled inside BatchForge+ since v1.1.0 under LGPL-2.1.
Purpose: Media probing, transcoding, muxing, audio processing, image sequence processing, and related media operations.
Official legal reference: ffmpeg.org/legal.html.
b3LAB source-availability mirror: b3lab.io/ffmpeg-source.

Distribution status for this build: FFmpeg and ffprobe are bundled with BatchForge+ since v1.1.0. The app ships its own LGPL-2.1 FFmpeg 7.1.2 build inside the application bundle at BatchForge+.app/Contents/Resources/bin/, accompanied by 23 dynamic libraries in BatchForge+.app/Contents/Resources/lib/ (freetype, harfbuzz, fontconfig, libass, libmp3lame, libopus, libvorbis, libvpx, libdav1d, libwebp, libsnappy, and others). All binaries and libraries are individually code-signed with the b3LAB Developer ID and notarized by Apple. BatchForge+ does not require Homebrew or any user-side FFmpeg installation. A documented user-override path at ~/Library/Application Support/BatchForge+/bin/ allows power users to substitute the bundled build with their own — this mechanism satisfies the LGPL-2.1 Section 6 library-substitution requirement.

LGPL-2.1 compliance: the bundled FFmpeg is built with --disable-gpl --disable-nonfree and explicitly excludes libx264, libx265, libxvid, libfdk-aac, libvidstab, frei0r, librubberband, libpostproc, libxavs / libxavs2 / libdavs2 / libuavs3d, libtesseract, libopencv, and libsmbclient. The build is verified by Scripts/build_ffmpeg_lgpl.sh against a forbidden-token list; the configure invocation and verified-binary record are mirrored at b3lab.io/ffmpeg-source/FFmpeg-BUILD-CONFIG.txt. The full source-code availability page (LGPL-2.1 Section 6(b)) is at b3lab.io/ffmpeg-source. The complete component license list and upstream URLs are shipped with every download in the DMG installer's LICENSES/ folder.

Codec patents: hardware-accelerated H.264, HEVC, ProRes, and AAC encoding rely on Apple's VideoToolbox and AudioToolbox frameworks, which are part of macOS. Apple is the patent licensee for these codecs on macOS for application-developer use; no separate patent license is required from b3LAB or the licensee for the bundled encoders. AV1 (libdav1d decode), VP8/VP9 (libvpx), Opus, Vorbis, FLAC, WebP, and WavPack are royalty-free by design. MP3 patents expired in 2017. Patent obligations for large-scale commercial distribution of H.264 or HEVC encoded output (≈ 100,000+ titles per year) are governed by the end user's own distribution license under the relevant patent pool, not by b3LAB. The detailed legal analysis is in b3LAB - BatchForge+__LEGAL.md inside every DMG.
