I didn't keep screenshots from when I tested that, but what happens is with 50i the deinterlacer will treat two fields from one same image (as happens in 2:2 film mode) as being from two different images and will try to analyse motion between them and also the next field to produce two output frames. As they are from the same image it won't find much motion, but very fine detail will appear to be shimmering.
With 30i it will completely mess up the 3:2 cadence and you'll see moiré and aliasing.

It seems interlacing will follow us (SAT amateurs) for a long time in a future:

from 20210614-205013_TRT 4K.mkv (28 MB) https://transfiles.ru/cum1l
It's a pity I didn't record from live translation of that match to see was interlace artifacts or not (I'm sure there wasn't artifacts).

Studio content has too many overlays, so it doesn't provide an accurate example. The actual game play would be better... But it looks progressive to me!

I use Kodi DSPlayer as my main player... today I've finally managed to get a RTX3070, preparing for when my new 4K TV will be here.

As such I have tried playing back some 4K HDR files (tonemapped through madVR). Initially I got all strange colors, blocks, general crap... At first I did not understand, then I realized that I had tried, years ago, to decode through the Lentoid HEVC decoder, as an experiment. I removed that from my system aaaand... there is pretty much no way I can get LAV Video to be used to decode HEVC. I have unregistered Lentoid, I have selected LAV Video, nothing... video starts but there is sound and no video.

I tried with both MPC-HC and MPC-HC BE and even though I deselect the internal filters and place LAV Video as preferred, they both fall back to the internal filter (MPC-HC stating "Lav Video (internal low merit)"). It's as if LAV is not usable for HEVC (HEVC is selected in configuration).

I have upgraded to 75, downgraded to 74.1, reupgraded to 75, nothing changed. I restarted the machine too (Windows 10 x64).

I wonder if Lentoid HEVC set LAV's merit very low.

This is a free utility that makes it easy to see and change filter merits:
InstalledCodec
LAV Video and Audio should be 0x00800003, LAV Splitter should be 0x00800004 (values in hex). Higher merit is the first to be used.

Very late last night (I write from Europe) I solved it by completely uninstalling LAV and then reinstalling (before I was upgrading and downgrading in place, not passing through uninstall).

I am sorry not to have tried what you suggested because I'm left with the curiosity to understand what happened.

LAV's merit being set very low could be an explanation but can you set the merit of a DS filter only for a specific codec? Because H264 material was working just fine. And, also, with Kodi DS player you can tell the program which filters to use, ignoring the merits system. And yet it wasn't working.

Mystery will probably remain but I have solved the problem.

Is that a 1080i feed downconverted from original 4K progressive? Or a 4K progressive feed with an insert from a badly deinterlaced 1080i feed?
I see this on Formula 1 too, on onboard cameras the white/coloured pattern on the kerbs changes too much between consecutive fields and it confuses the deinterlacer.

LAV Filters 0.75.1
Code:
LAV Splitter
- Changed: AV1 files with no extradata will now generate a format header with stream information for decoders to use
- Fixed: Improved stream selection when multiple "default" video tracks are present

LAV Video
- Changed: Updated dav1d for significant improvements in AV1 10-bit decoding performance
- Changed: AV1 hardware decoding will more reliably engage when provided with additional stream information from the demuxer

LAV Audio
- Fixed: Opus decoding had audible artifacts in some files in 0.75
Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

Check 0.75 Release Notes if you missed them!

AV1 software decoding of 10-bit content is now significantly faster with the new version of dav1d.

Other then that, just few small fixes and updates.

Take care, and have fun!
