FFmpeg Forge 2.1.5

✨ FFmpeg Forge 2.1.5 for Windows
✨ [NEW] FFmpeg Forge 2.1.5 for MacOS
✨ [NEW] FFmpeg Forge 2.1.5 for LINUX

FFmpeg Forge 2.1.5 brings QTGMC deinterlacing for interlaced videos (DV, DVD, TV recordings, 1080i camcorders) and, for the first time, a portable edition for macOS, on Apple Silicon and Intel Macs.

🎞️ Deinterlacing with QTGMC (Windows and macOS)

✦ New "Deinterlacing" option in Video settings, with three choices: Off, QTGMC double rate (50p / 60p) and QTGMC same rate (25p / 30p).

🎬 Double rate turns every field into a frame: 25i becomes 50p and 29.97i becomes 59.94p, for the smoothest motion. Same rate gives one frame per original frame: 25i becomes 25p and 29.97i becomes 29.97p.

🧭 Field order: Auto uses the order written in the file (top or bottom field first). If motion judders back and forth, force TFF or BFF. Forcing an order also deinterlaces files that are not flagged as interlaced.

✅ Only interlaced videos are processed. Progressive videos are left as they are, and the log says so.

🧠 QTGMC is QTempGaussMC from vsjetpack, running on VapourSynth R81 with its plugins (MVTools, znedi3, zsmooth, resize2, akarin, vszip, BestSource). It runs first, before every other effect, so the rest of the chain gets clean progressive frames. Trim, audio, PNG/JPG SEQUENCE, cover and every format keep working.

📥 "Install QTGMC (VapourSynth)…" installs everything once: uv, Python 3.12, VapourSynth and the plugins at tested versions, about 150 MB. The installer checks that QTGMC loads before it finishes.

🛟 Until QTGMC is installed, FFmpeg's bwdif deinterlacer is used with the same settings, and the log says so clearly.

🐢 QTGMC is slow: it is the best quality option, not the fastest. On a plain conversion, bwdif is much faster.

🍎 New: FFmpeg Forge for macOS (portable)

💻 A native Mac application with the same blue and gold design and the same layout as the Windows version: files in the middle, every setting in one column on the right, CONVERT at the bottom.

📦 Portable: everything is inside FFmpeg Forge.app, FFmpeg included. Copy it to Applications, a USB stick or an external drive. Requires macOS 12 Monterey or later.

✅ Included on macOS:
Video, audio and image conversion with the main formats and presets of the Windows version (MP4, MKV, MOV ProRes, DNxHR, WebM, GIF, MP3, FLAC, WAV, PNG, JPG, WEBP…)
Quality, encoding speed, resolution, frame rate, rotation, trim and destination
Filters: preset library and your own FFmpeg filters
Compression assistant: analysis, real measurement on 3 samples and Optimized compression
Cover / thumbnail, PNG/JPG SEQUENCE and QTGMC deinterlacing
Apple VideoToolbox hardware encoders (H.264 and H.265)
Drag and drop of files and folders, remaining time for each file

⏳ Not available on macOS yet: NVIDIA RTX Video, NVENC and every CUDA feature (they need an NVIDIA GPU), Denoiser IA, Python / ONNX AI, VisionNext, SeedVR2, Scale / OptiScaler, Spatial Audio and DSD export. The AI features on the Apple GPU are planned for a later version.

🧩 QTGMC on macOS needs macOS 15 Sequoia or later (the VapourSynth plugins for Mac are published for macOS 15). On older versions, bwdif is used.

🔧 Improvements (Windows)

🎯 NTSC frame rates (29.97, 59.94, 23.976) are now written as exact fractions (30000/1001, 60000/1001…) when a frame rate is set.

🛡️ Unchanged and preserved (Windows)

The compression assistant, cover / thumbnail, NVIDIA RTX Video, PNG/JPG SEQUENCE, the live before / after comparison, every preset, codec and format, the AI features and your saved settings work exactly as before.

📦 Downloads

🪟 Windows

🎒 FFmpegForge-2.1.5-Portable.rar (about 206 MB): everything included, FFmpeg Forge 2.1.5 with FFmpeg 9.0.2 full and ForgeRTX. Extract the whole archive anywhere and run FFmpegForge.exe.

🪶 FFmpegForge-2.1.5.rar (about 0.7 MB): normal edition for your own FFmpeg (C:\FFmpeg\bin or next to the .exe).

🧩 Denoiser IA models (HAT L, DAT, SPAN): use FFmpegForge-2.0.0-Denoiser-Models.rar, unchanged. Extract it next to FFmpegForge.exe (models folder).

🍎 macOS

🚀 FFmpegForge-2.1.5-macOS-AppleSilicon.zip (about 140 MB): for Macs with M1, M2, M3 or M4, with FFmpeg 7.1.

🖥️ FFmpegForge-2.1.5-macOS-Intel.zip (about 164 MB): for Intel Macs, with FFmpeg 6.1.1.

🔓 First start on Mac: the app is not signed by Apple. Right click FFmpeg Forge.app, choose Open, then Open again. On macOS 15 and later, if it is blocked, go to System Settings, Privacy & Security, and click "Open Anyway". If macOS says the app is damaged, run this in Terminal: xattr -dr com.apple.quarantine "/path/to/FFmpeg Forge.app"

ℹ️ VapourSynth, vsjetpack and the plugins are not included in the archives: the installer downloads them from PyPI.
