They would remove the interlace to bring the framerate to 50fps before
encoding. There are many methods of doing so, ffmpeg can do this for
example.
This article
https://superuser.com/questions/253691/how-to-convert-108050i-72050p-using-ffmpeg
says, "Just like interlacing progressive content divides each frame into
2 fields, thus doubling the frame rate, the common method of
deinterlacing is to combine each 2 fields into 1 frame, which reduces
the rate by 2, thus taking 50 into 25fps. You can of course double each
final frame, but that does not provide any benefit."
Do you disagree?
Best wishes
