⏱️ Performance

Note: The following results were benchmarked on FP16 engines inside ComfyUI, using 2000 frames consisting of 2 alternating similar frames, averaged 2-3 times

Device	Rife Engine	Resolution	Multiplier	FPS
H100	rife49_ensemble_True_scale_1_sim	512 x 512	2	45
H100	rife49_ensemble_True_scale_1_sim	512 x 512	4	57
H100	rife49_ensemble_True_scale_1_sim	1280 x 1280	2	21

🚀 Installation

Navigate to the ComfyUI /custom_nodes directory

git clone https://github.com/yuvraj108c/ComfyUI-Rife-Tensorrt
cd ./ComfyUI-Rife-Tensorrt
pip install -r requirements.txt

🛠️ Supported Models

The following RIFE models are supported and will be automatically downloaded and built:

• rife49_ensemble_True_scale_1_sim (default) - Latest and most accurate
• rife48_ensemble_True_scale_1_sim - Good balance of speed and quality
• rife47_ensemble_True_scale_1_sim - Fastest option

Models are automatically downloaded from HuggingFace and TensorRT engines are built on first use.
