So we have a 25FPS framerate looking like THIS: O-U-O-U-O-U etc…. (O = overexposed and U = underexposed)
The result we need is an 25 fps overexposed and a 25fps underexposed stream which are saved as image sequences.
How we do it:

A = FFVideoSource(“..\RAW.MOV”)
A = ConvertToRGB(A, matrix=”PC.601″, interlaced=false)
A = Converttoyv12(A) # convert to yv12 needed for Interframe
A = selecteven(A) # select even or odd frames and interpolate them
A = assumefps(A, 25) # Interframe doesn’t work with 12,5 fps
A = InterFrame(A, NewNum=50, NewDen=1, GPU=false, FlowPath=ScriptDir()+”..\Avisynth-plugins\”)
A = assumefps(A, 25)
A = trim(A, 1, 0)
A = ConvertToRGB(A)
A = ImageWriter(A, “..\frames\A”, type = “jpg”)

B = FFVideoSource(“..\RAW.MOV”)
B = ConvertToRGB(B, matrix=”PC.601″, interlaced=false)
B = Converttoyv12(B) # convert to yv12 needed for Interframe
B = selectodd(B) # select even or odd frames and interpolate them
B = assumefps(B, 25) # Interframe doesn’t work with 12,5 fps
B = InterFrame(B, NewNum=50, NewDen=1, GPU=false, FlowPath=ScriptDir()+”..\Avisynth-plugins\”)
B = assumefps(B, 25)
B = ConvertToRGB(B)
B = ImageWriter(B, “..\frames\B”, type = “jpg”)

return Interleave(A,B)

It would be awesome if we could use information of the underexposed frame for the overexposed interpolated frame and vise versa to get a better result.
Is there any chance this is possible somehow?

Kind regards Sander
