Just to inform you that vs-rife has got major performance improvement in recent releases. Tested with the latest vs-mlrt (v15.8) and vs-rife (v5.6.0) on my low-end i5-13400F and 4060 Ti:
# from vsmlrt import BackendV2, RIFE, RIFEModel
# clip = RIFE(clip, model=RIFEModel.v4_25, backend=BackendV2.TRT(num_streams=3, fp16=True, output_format=1), _implementation=2)
1080p: 84.23 fps
720p: 210.37 fps# from vsrife import rife
# clip = rife(clip, model="4.25", trt=True)
1080p: 102.99 fps
720p: 249.36 fps
