▸ More about BatchForge+
Native macOS batch workbench with four workflow modes — Batch Transcode, Audio-Only, Segment Join, Image Export. Industry codec pack covers mainstream delivery (ProRes 6 profiles, HEVC 10-bit, H.264, HAP/HAP Q/HAP Alpha, VP9/WebM), broadcast & archival (DNxHD 7 SMPTE profiles, DNxHR 5 profiles, FFV1 lossless), and container wrap (MXF SMPTE 377M-1 OP1a, MKV). Hardware-accelerated via VideoToolbox with automatic SW-fallback. Self-contained: ships its own LGPL-2.1 FFmpeg 7.1.2 inside the app bundle — no Homebrew, no Terminal, no setup.
// FEATURES
What BatchForge+ does
Four workflow modes, bundled FFmpeg 7.1.2 — Batch Transcode, Audio-Only, Segment Join, Image Export. No CLI, no Homebrew, no setup.
4 modes · Mainstream + Broadcast + Container Wrap
One source → many outputs (codec × resolution × FPS). VideoToolbox HW acceleration for ProRes, H.264, and 10-bit HEVC with automatic SW fallback on incompatible codec/container combos (e.g. ProRes-in-MXF forces prores_ks SW). Image Export now exposes Use Source Resolution, Limit FPS, and Fit / Fill / Stretch. Segment Join can stream-copy compatible inputs or retry as re-encode.

Watch Folder · XML import · presets · preflight
Automate repeat work and prevent broken renders before they start. Watch Folder creates Input, Output, Processing, and Error subfolders, stages stable files into Processing, and auto-starts by default. Validation runs before each render — drawtext availability, image-sequence gaps, LUT files, trim ranges, timecode dependencies, and bitrate syntax.
▸ Show all features
- Watch Folder poll interval defaults to 2.5 s; stable files are detected by unchanged file size
- Edit-timeline import (FCP7 XML / FCPXML) — File → Import Edit (XML) (⇧⌘I), an "XML Import" button, or drag an
.xml/.fcpxmlonto the queue. Each cut from a Resolve / Premiere / FCP7 timeline becomes its own trimmed queue item in cut order, then batch-renders to individual clips. File naming combines source + cut order + timeline timecode via editorial tokens ({#}sequence ·{tc}timeline timecode ·{dur}duration, auto-applied on import). Conform-friendly: a Relink button repoints offline sources by filename across folders, and offline/undecodable clips import as a timed placeholder so the edit conforms end-to-end. Exports are raw source extracts — timeline color grades, reframes and transitions are not reproduced. - Presets and projects are JSON files under

// REPAIR & FORENSICS
Recover footage other tools reject.
Damaged cards, dropped frames, corrupt recordings, offline media in a conform — BatchForge+ pushes the render through instead of aborting, so a broken source still lands a usable file.
Push through decode errors
Forces FFmpeg through CABAC / NAL / bytestream errors instead of stopping at the first bad packet — for corrupt MP4s, damaged SD-card footage, and partial recordings.
Drop corrupt frames cleanly
Cut Bad Frames removes corrupt frames and fills the gap with Freeze, motion-compensated Interpolate (minterpolate), or Blend. A Container Resync pre-pass rebuilds NAL / parameter-set structure by stream-copy before the render — no re-encode.
Forensics & conform safety-net
Drop-Window Export writes context frames (PNG / JPG / TIFF / EXR) around every dropped frame for manual repair, with auto-detect of corrupt sources. Offline or undecodable clips render as a timed red placeholder (silent audio) so an imported edit conforms end-to-end — relink & re-render later.

- Tested with macOS 15.6 (Sequoia) · Apple Silicon (M1+) · macOS Tahoe. Intel Macs not currently supported.
- FFmpeg + ffprobe bundled inside the app. BatchForge+ ships its own LGPL-2.1 FFmpeg 7.1.2 build in
Contents/Resources/bin/plus 23 LGPL/BSD/MIT runtime libraries inContents/Resources/lib/, all individually code-signed with the b3LAB Developer ID and notarized by Apple. The preflight check verifies bundled binary integrity, drawtext availability, and write permissions on the output folder. No system FFmpeg installation is required. - Power-user FFmpeg override. If you want to substitute the bundled FFmpeg with your own build (for example, to enable software
libx264/libx265encoders that are excluded from the LGPL build), place your binary at~/Library/Application Support/BatchForge+/bin/ffmpeg—FFmpegLocatorprefers it over the bundled one. This is the documented LGPL-2.1 Section 6 substitutability mechanism. - All encoding happens locally on your machine. No cloud, no upload, no telemetry.
- Alpha preservation requires an alpha-capable output codec (HAP Alpha, HAP Q Alpha, ProRes 4444, PNG/EXR sequence) and an FFmpeg build that supports it.
- Hardware acceleration (VideoToolbox / AudioToolbox) availability depends on Mac model and codec — these encoders are part of macOS.
- Source format and codec support is limited to what your installed FFmpeg can decode/encode.
- Loudness presets target their respective standards (EBU R128 −23 LUFS, ATSC A/85 −24 LUFS, etc.) — final delivery should still be measured by the receiving studio.
- Edit-timeline import (FCP7 XML / FCPXML) exports raw source extracts per cut — timeline color grades, reframes, transitions and Fusion/AE comps are not reproduced. Speed / time-remap clips import with raw in/out (may not be frame-exact), disabled clips are skipped, and offline media imports as a placeholder to relink + re-render.
- Free tier: MP4 (H.264) up to 1080p — unlimited count, no watermark, no time-cap. Pro unlocks HEVC / ProRes / HAP / DNxHD/HR / FFV1 + MXF/MKV wrap + DPX/EXR + resolutions above 1080p. There is no trial watermark or time-limit.
- Render jobs run sequentially through the queue (one FFmpeg process at a time); the Performance modes (Background / Balanced / Fast), Low-Priority FFmpeg and Heavy-Jobs-Exclusive tune that single process rather than spawning parallel encodes.
- Native macOS app — Apple Silicon (M1+). Intel Macs not currently supported.

// USECASES
Who uses it, and how.
Real production scenarios. Each setup is one focused signal path — no glue scripts, no capture detours.
Same-day highlight reel for the dinner reception
A wedding videographer needs to project a 90-second highlight cut at the reception. Edit done in Premiere by 21:00; reception starts 22:00. BatchForge+ exports four formats from the export folder: ProRes for backup, H.264 for the venue projector, 9:16 vertical for IG-Stories, 1:1 square for IG-Feed. One drag, four delivery formats, projector-ready before dessert.
One episode, four languages, four resolutions
A creator runs four YouTube channels (DE / EN / ES / FR), one episode per week, each at 1080p and 4K. Sixteen files per episode is a half-day of manual encoding. BatchForge+ holds a single watch-folder rule chain — drop the master with the language tag in the filename, all sixteen versions land in their per-channel folders before the audio dub is even posted.
Six podcast shows, three deliverables each, one preset chain
A podcast network runs six shows. Each episode needs a loudness-normalized MP3 (Spotify), AAC (Apple Podcasts), and a 60-sec 16:9 trailer (IG-Reels). Eighteen deliverables per week if done by hand. BatchForge+ holds one preset chain per show; producers drop WAVs into the show's folder, network publishes from the output folder.

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.
