Wondering...
Why not resizing with Trbarry's great SimpleResize plugin?
Some cons i'm not aware of?

Like it was made for speed instead of quality?

I only use it for the credits portion of my movie, becauae it creates an even smaller file that BilinearResize.

FWIW, the quality depends upon whether you want a resize to also do some filtering for you. I often have clean digital captures or rips that also have already been a bit filtered for some reason. In this case I prefer a crisp (but not sharpened) resize.

For instance, this was SimpleResize'd:

avih -

The sample was a TV episode, upconverted by the network to a 1920x1080i ATSC transmission. I captured it with my WinTVHD card, cropped a bit, threw away the odd lines, and then resized the remaining 1408x528 clip to 640x480 for this sample, using my SimpleResize Avisynth filter.

see www.trbarry.com/Readme_SimpleResize.txt

But for my own purposes recently I've been just keeping them at 704x528. I like detail, even if it costs more disk space.

thanx for the reply, but i probably didn't ask clearly enough.

i didn't mean how do u capture, but how does the filter work.

i.e. do u use nearest neighbour or bilinear or bicubic interpolation while resizing. i.e. what method does the filter use for resizing.

;) cheers

Sorry, I thought that was in the readme file and the thread linked above. It is just a simple 2-tap linear interpolation in both dimensions.

Since it doesn't try to do any filtering and isn't more general purpose I was able to MMX/SSE/SSE2 optimize it somewhat for some better speed. If you are curious, the source is also in the zip:
