Since protheus v4 is made for old stamped videos
see below
n this new version, we aimed to expand the capability of the current Proteus by handling more severe cases (e.g. more noise, compression, etc) and more input video types (progressive, interlaced, and interlaced progressive). This version can also enhance human faces better than the Proteus v3.
I am wondering the protheus interlaced then the auto bit setting seems NOT an error but it will create a 50 interlaced Video which seems better than 50 progressive as if it tries to go back to the old PAL interlaced video the results look better than the progressive as if it wants to deinterlace without the need for hybrid software
