Any way to improve deinterlacing quality?

So I got this interlaced video I'm trying to deinterlace however I am curious if there's anyway to further reduce the noticeable artifacts from deinterlacing.

Below are three sets of screenshots to compare the quality of three different deinterlacers (well, two deinterlacers and one field matcher) I've tried TFM, TDeInt, and QTGMC+.

I should clarify that the source I'm working with I believe does not contain progressive frames, I believe most if not all the frames are interlaced.
Here's a five minute sample for anyone to double check

The following sets of screenshots are ordered as follows from top to bottom:
- raw (only using source filter)
- TFM
- TDeInt
- QTGMC+

Here are the various function calls I used when using the various deinterlacers, note these were not all in the script at once, just one at a time.

Code:
QTGMCp(preset="Slower", FpsDivisor=2)
TDeint()
tfm(PP=5, cthresh=8)
