NVOF new parameters?

I have SVP 4 license, and I have svp manager running in background disabled.

I want to run a custom script with nvof parameters.

This below part of my script used to work but no longer.

global smoothfps_params = "{gpuid:11,gpu_qn:2,rate:{num:144,den:1,abs:true},algo:23,linear:true,scene:{mode:0,blend:false}}"

global nvof = 1
global nvof_blk = 4

input=last

nvof_src = input.BilinearResize(input.width/nvof_blk*4,input.height/nvof_blk*4,src_width=-(input.width % nvof_blk),src_height=-(input.height % nvof_blk))


SVSmoothFps_NVOF(input, smoothfps_params, nvof_src=nvof_src, mt=cores+1)

Getting an error: "Script error:SVSmoothFps_NVOF does not have an argument 'nvof_src' "

Can someone tell me what the new nvof parameters are so I can use a custom script?

I looked at the "last generated script" but that didn't show anything.

Thanks in advance.
