ATEM Mini Switchers - 1080i deinterlace problem

Do any of you know how to make ATEM Mini switchers deinterlace process correctly?

I have Atem Mini to Extreme ISO, none of them correctly deinterlace 1080i signal. They only line doubling horrible looking process.

I have been mailing to Blackmagic, all the answers are, saying, they will pass it to their developers. It has been years, nothing has been changed.

What are you feeding it?

I just tested a 1080p50 signal converted with a Decimator MD-HX to 1080i50 and it shows up fine on preview and PGM out of my Atem Mini Extreme.

Sources are from Canon C100, C300 cameras, feed to Atem Mini, Atem Mini Pro, Atem Extreme, Atem Extreme ISO, Atem Television 4K.

C100 and C300 MK1 only outputting 1080i signal to SDI and HDMI (even you setup 1080p for recording)

Decimator MD-HX to 1080i50 ===> they should look good I believe. Many cameras outputting 1080i PsF signal, that is problem.

Canon C100 and C300. they are pushing PsF. Atem needs to leave it alone or need to properly deinterlace. MANY cameras pusing Psf.

+1 for Blackmagic doing something about this. Please do a firmware update to stop deinterlacing unnecessarily!

I totally agree, I think it's a big problem!
