K-ON! Live, Let's Go! It was held 4 years ago in Yokohama, and later released in BD. However I didn't find any satisfying BDRips, so I've done one on my own. Explanation why this is encoded in 1920x540 (and use --sar 1:2 to force players to output in 16:9) For the source video in BD, every two consecutive rows are identical(except for background quantization noise), meaning the images look like: 02468 02468 13579 13579 ...... if left alone, it will result in blurring and aliasing(see the first picture below); remove duplicated rows and let video players(I'd recommend those with madVR ) do the twice-height-resizing, the situation got much better(see the second picture below):  pp: adaptive denoise, deband, deblock, sharpen major encoding parameters: ref=10 / deblock=1:0:0 / me=tesa / subme=10 / fade\_compensate=0.00 / psy\_rd=0.80:0.00 / me\_range=24 / fast\_pskip=0 / chroma\_qp\_offset=-2 / fgo=0 / bframes=8 / b\_adapt=2 / weightb=1 / weightp=2 / keyint=720 / keyint\_min=1 / mbtree=1 / crf=19.0000 / qcomp=0.70 / aq=3:0.90 / aq2=0 / aq3=0
