SAMA: Factorized Semantic Anchoring and Motion Alignment for Instruction-Guided Video Editing

This repository provides an FP8 quantized version of syxbb/SAMA-14B.

SAMA (factorized Semantic Anchoring and Motion Alignment) is a framework that factorizes instruction-guided video editing into semantic anchoring and motion modeling. It improves edit precision while preserving temporal dynamics from the source video by establishing reliable visual anchors through sparse frame prediction.

Code: https://github.com/Cynthiazxy123/SAMA

🚀 Quick Start

🛠️ Installation

bash

git clone https://github.com/Cynthiazxy123/SAMA
cd SAMA

conda create -n sama python=3.10 -y
conda activate sama

pip install --upgrade pip
pip install -r requirements.txt

▶️ Inference

To run inference, you need to prepare the base Wan2.1-T2V-14B model directory and the SAMA checkpoint. Edit the variables in the provided script (e.g., MODEL_ROOT, STATE_DICT, SRC_VIDEO, PROMPT) and run:

bash infer_sh/run_sama.sh
