[HELP] how to encode a ProRes file using x265 to get the same parameters?

[Selur]

Overall bitrate is simply file size / video length.

and the encoded file is REC709, how to set to make it Color space YUV, thanks.

Assuming you know and understand what Rec.709 means.
Color Matrix signaling can be changed in the corresponding tab.
Conversion between color matrixes can be done through for example 'ColorMatrix' filter.
