I noticed a weird glitch in one of my videos, and I'd love to hear your opinions on its possible causes and fixes.

As you can see, the animation looks like it's interlaced.
I tried playing it with MPC-BE v1.5.8, VLC v3.0.16, Google Chrome's player, and even Dropbox' player but the glitch was still there.
I also re-encoded it using ffmpeg v4.4 with the following parameters, but still no luck:

You're out of luck with that clip. Who ever created it did not handle the titles; they were interlaced originally,
but the fields have been merged and blended into the progressive frames -
Wild guess: someone used either frame interpolation to get it's source to a higher fps, or used blend deinterlacing in a bad way.

Badly blended interlaced video. You can blend it even more until lines are gone but that's about it

Just a little tip for future use.
Always, if possible, post samples as attachments in the topic. Then they are available for latter users who could have similar problems when the external sources are no longer available.
