Why can't I deinterlace my footage?

I'm using Resolve 17 Public Beta 8.

My footage is clearly interlaced, whoever filmed it filmed it at 24fps and MediaInfo says it's progressive.

In Resolve 16 it worked perfectly. Why did they have to mess it up?

I cannot deinterlace this footage anymore. I'm doing it the old fashioned way in MPEG Streamclip and then bringing it into Resolve 17.

Can you post a sample clip for us to try?
Also whats the setting you are using in Project Settings -> Image Scaling -> Deinterlacing Quality

Something is very wrong here! There has never been a 24FPS interlaced format - it just doesn't exist! I'd love to know how this clip came about - some sort of transcoding before you got it no doubt.

In Resolve 17 you need to flag the clip in attributes at 'Upper field first' for the deinterlacing to kick in now (rather than telling it to deinterlace, you need to tell the clip that it is interlaced - because the metadata is not accurately describing the actual content of the clip). Resolve will then say 'You have interlaced content, but a progressive timeline therefore I need to deinterlace'.

It's a really badly interlaced file they gave me of my grandad's funeral. It's meant to be PAL but they must have mucked up the editing settings.

I've tried deinterlacing it in Shutter encoder, both top field first and bottom field first and both give really bad results. See image:

I'm afraid it has been scaled without de-interlacing first.
