The highest - 1920x1080/60i

I didn't see that 'deprecated'. I copied suggested command lines from google 
searches: however, I most commonly saw yadif=3:1,... but I quickly found that my 
fields were reversed, I know that jiggle very well now! I checked the man page, 
and switched to yadif=3:0,... and the jiggle was fixed.

Well I tried 1 and 3 for the high resolution. I did briefly try 0 for the lower 
resolution test, but then I figured that it was putting out data that I was then 
going to discard later with the 'scale' filter. I reasoned that using the 
'tfields=0' filter was more sensible because it was not creating the data in the 
first place, so it should be faster.

I chose the tests that I thought had a chance of being efficient... but if you 
think it's interesting, I could do a full matrix of tests, even the insane ones!

Only one person downloaded the files so far, I'd be interested to know if this 
person thought it was a good test for deinterlacing, because I 'designed' it to 
be that.
