That type of artifacting is usually the result of temporal filtering.

Oh, wow - you're doing video work only on a computer? If you're
producing content for viewing on a TV set you really really need to
have at a TV set (better yet a production monitor but a regular
TV will be better than nothing). The difference between a TV and a
computer monitor is substantial.

I think you overlooked 'yuvdeinterlace' ;)
My preference is never to deinterlace at encoding time - it's a
lossy process that can introduce artifacts. If you really want
deinterlacing it usally can be done in the playback software (vlc,
mplayer, etc).

Sure you can. y4mscaler will crop very nicely.
When creating DVDs I use the cropped D1 frame size (704x480) instead
of the larger 720x480. How do you get y4mscaler to do that? Easy:
y4mscaler -O sar=src -O size=704x480
Can't get much easier than that. Can you? ;)

Ok - but when you're ready to step up to the next level of quality
you're at least aware of the possibilities.
