Delete all that knowledge? Are you serious? Sometime later we might need such infos. Not believing what I read, Koepi

Well, I've been trying SansGrip's Blockbuster a little more and have had amazing results with this setting: Blockbuster(method="dither",block_size=3,luma_offset=-2,luma_threshold=30,detail_min=1, detail_max=30) Although, I saw someone else post the block_size=3 and gave it a try, but I think it should divide evenly into the frame, no? On the encode I just tested of a TV cap of a cartoon, I had to look out for dark blocks watching through my TV, while normally they are so glaring it's unacceptable. Dither seems to be the key, as it stop the blocks from having a 'life of their own' (i.e. moving around or flickering where the image is relatively static). SansGrip mentions in the readme that dither is experimental so maybe this can still be improved. The place where I see blocks the most now is in somewhat bright solid colour areas. Instead of increasing the variables, I wonder if blockbuster can be modified to tackle a frame at both ends of the luma scale? Anyways try it out and report back your findings. Get his plugin

Give the 'sharpen'-method (instead of 'dither') a try; very nice, too.

Removing existing mpeg2 macroblocs and not reproducing mpeg4 marcoblocks are two completely different things...;) Blockbuster performs the first one, lumafilter+unfilter make sure about the second I'd go with Teegedeck on this one : "sharpen" seems to be the key for me regards, george PS: u could try the luma_offset=-2 option of blockbuster with unfilter(+x,+x) as a combination of both :D

Ok, I'm trying out sharpen right now to see the results. Regarding luma filter/unfilter. Almost every post I've seen is from someone using the luma function that's part of mpeg2dec3. I'm doing tv captures so obivously, I am not using mpeg2dec3. How do I offset luma without it, if I'm not using blockbuster. I saw one post using lumafilter(), but I can't find anything on this. Is this part of aviysynth 2.5? I'm still using 2.07.
