Khamul, I'd regard the MSU filters as a double edged sword. they tempt you with how good they are (can personally vouch for their sharpen filter, it's bloody marvellous) and then they hit you over the head with how bloody slow they are.

I don't hink I've come across so many good(but unoptimised filters) eg

sharpen filter runs at 1-2fps on a PIII933, 1.7ghz athlon and a P4 2.8. ie it's not been optimised in the slightest to take into account processor speeds. which is disappointing.

I queried MSU on this, complimenting them on the quality of the filter etc but they haven't bothered to reply in three weeks.

the deinterlace article was an interesting read but bear in mind that the example given in the article is a worse case. TNG particularly is a bad source using as it does a mix of blended fields, interlaced, progressive and other sources.

I used smart deinterlace and blended fields from a number of different captured material and they've been fine with no ghosting at all, so while I can appreciate what the author is saying, bear in mind that his offered solution solves the problem for THAT clip. it won't necessarily hold true for other clips.

all I can suggest is you experiement and see for yourself, nothing can better personal experience in this field.
