FFmpeg Forge 1.1.3

✨ New

🌱 SeedVR2 for videos and images: ByteDance Seed's one step diffusion model. It removes blur, noise and compression artefacts and rebuilds fine detail. On videos, the result stays consistent over time.

🧠 Choose from 10 models:

3B: GGUF Q4_K_M, GGUF Q8_0, FP8 or FP16.

7B: GGUF Q4_K_M, FP8 mixed (recommended for 24 GB cards) or FP16.

7B Sharp: GGUF Q4_K_M, FP8 mixed or FP16.

The list shows the VRAM each model needs. Each model downloads automatically the first time you use it.

🎛️ Settings:

Output size: ×1.5, ×2, ×3, ×4, 720p, 1080p, 1440p, 4K or restore only.

Batch size and colour correction (LAB, wavelet, wavelet adaptive, HSV, AdaIN).

Input noise, latent noise and seed.

Chunking with temporal overlap for long videos.

VRAM savers: BlockSwap, VAE tiling and RAM offload.

Attention backend (SDPA, Flash Attention 2, SageAttention 2 or 3), torch.compile and CUDA GPU.

📥 "Install SeedVR2…" button: it downloads the official SeedVR2 command line (Apache 2.0), uv with Python 3.12 and PyTorch CUDA 12.8 (about 4 GB). It runs in a console window so you can follow the progress. An existing install works too, ComfyUI included: use "SeedVR2 folder…".

🔗 Keeps the rest of FFmpeg Forge: trim, rotation, Denoiser, filters, output format, codec and audio still apply. FFmpeg prepares the source, SeedVR2 restores it and FFmpeg encodes the final file.

💡 Clear hints for common problems: out of VRAM, incomplete Python environment, CUDA not available.

🔧 Also in 1.1.3

The experimental DLSS and DLSS 5 options added after 1.1.2 have been removed.

The startup fix of the portable edition is kept, along with the error log (FFmpegForge_error.log).

⚙️ Requirements for SeedVR2

An NVIDIA GPU with CUDA and a recent driver. For the 7B models, 24 GB of VRAM is recommended; use 3B, GGUF or BlockSwap on smaller cards.

About 4 GB for the installation, plus 2 to 16 GB per model.

It is slow: a 7B model needs several minutes per minute of video.

📦 Downloads

🎒 FFmpegForge-1.1.3-Portable.rar (about 204 MB): everything included, FFmpeg Forge 1.1.3 with FFmpeg 9.0.2 full and ForgeRTX. Extract the whole archive anywhere and run FFmpegForge.exe. SeedVR2 installs into the SeedVR2 folder next to it.

🪶 FFmpegForge-1.1.3.rar (about 0.6 MB): normal edition for your own FFmpeg (C:\FFmpeg\bin or next to the .exe). SeedVR2 installs into %LOCALAPPDATA%\FFmpegForge\SeedVR2.

ℹ️ SeedVR2, Python, PyTorch and the models are not included: the "Install SeedVR2…" button downloads them from their official sources.

⚠️ The executables are not code signed. If SmartScreen warns you, click "More info", then "Run anyway".
