I'm testing the new Super Scale feature but it seems there is a problem with interlaced footage when "Enable video field process" is checked.
As you can see from the video below, if "Enable video field process" and Super Scale are both enabled, the video is half height.



DaVinci Resolve 15 Beta 2
Source video format is MP4, 720x576 25fps Upper field

Tested on two systems:
- Laptop: Windows 10 Pro 1709, CPU Intel i7 3650, RAM 16 Gb, GeForce 750M
- Desktop: Windows 10 Pro 1709, CPU Intel i7 6800K, MB Asus x99-E WS USB 3.1, RAM 32 Gb, GeForce 970

I have the same result with DR15b2 on Mac OSX.

I'm seeing this behavior too in Beta 2. I'm on Mac OS X.

It's a serious problem, since I consider Super Scale most useful when you have to blow-up considerably, like SD archival footage to HD or even UHD.
When trying good HD into UHD, I saw pretty long rendering times without too much of a visual advantage over the usual scaling and a tad of sharpening.

Unfortunately, most of such archival material is interlaced…

Testing some interlaced sources (SD and HDV) just now in 15_b3 I'm not seeing this issue. It does appear to have been fixed, as per the 15_b3 change-log:
