Whatever further processing is done, I think that scaling down to 480

Looking more at the sample it does seem that the progressive scale and
encode have killed every fourth source frame by partially merging its
fields with previous and next.
fieldmatch and decimate can't really recover this.
If you just needed to play this (on a 60[/1.001]Hz screen) you can make
it look "slightly less crap" on the fly with mpv + lavfi eg.
mpv -fs
--vf=lavfi=[scale=w=1920:h=480,yadif=send_field:parity=tff:deint=all]
