Hi so yes the question is basically that
Can you plz suggest me best resize and sharpen filters for good sharpness and no blocky picture ...
with respect to Downscaling,Upscaling (DVD9) and also reducing/Compressing the file size of 720p/1080p Using x264 Encoder (MEGUI)
i have tried Lanczos and Lanczos 4 but i don't see any difference or is it my eyes which cant see the difference??
What Do U All Suggest??

Upscaling - i would give a chance to xxEDIx, for downscaling i would select spline based filters (spline 36 or 64).
Which resizing filter is best depends on your source. If your source is very sharp you don't want to use a resizing filter that sharpens (Bicubic, Lanczos, SplineXX, etc.) -- it will create over sharpening halos and blocky artifacts will be accentuated. nnedi3 (one of the "xxEDIx" filters pandy mentioned) or nnedi3_rpow2 is pretty good for upscaling but it's much slower than the regular resizing filters.
If you source has blocky artifacts you should us a deblocking filter before resizing.
For Anime you may consider Waifu2x interesting but it is painfully slow (nnedi3 is significantly faster when compared to waifu).
