After some suggestions and a fast review of x265 documents, quick conclusion comes out for the x265 encoder parameters.
My boss will reject those that are not heuristic methods so trivial trimming frame is not option.

keyint = 10*frame-rate. Long distance key-frames are best for Still frames, based on frame-rate without affecting decoder side too much. Default is 250.
scenecut = 30. Scene-cut detection is less aggressive to ignore some ghosting / blending scene. Default is 40.
rc-lookahead = 0.8*frame-rate. Add some more lookahead for frame-type decision. Default is 20.

Rest of the options i.e., bframes, ref and many motion prediction would be based on the presets by default. Feel free to give your comments about those custom options and or de-noising (mostly from high-bit-depth to 8-bit-depth dithering) or de-ghosting stuffs?
