Did not work as you said it would. It deinterlaced with the normal NVEnc deinterlacer (25i to 25p). Please also note the huge bitrate for a CRF 25 FPS 1080p video, in the context where the original was only 10.5 Mb/s in constant bitrate.
MediaInfo:
If needed, I can provide MediaInfo for the original file as well.
EDIT: Also, you said you tested this using the Bob deinterlacer from NVEnc. Bob also outputs 50 FPS, but at lower quality than adaptive, so you must have gotten the usual Bob and not adaptive.
