[Bunny Hat Raw]Masked Rider Kuuga 11-12 (SDTV) (10-bit x264,AAC)
Episodes 11 and 12 of Toei Channel's broadcast of the upscaled-to-widescreen component masters. Audio: AAC
Unfortunately, episode 11 shows that Toei didn't really look at the episodes before hitting the upscale button, as numerous shots have a black bar on the left side of the image.
This is because back in 2000 when the show was made, Toei didn't have the video centered. And when they recently upscaled it, they didn't bother re-centering it before cropping.
TL,DR tech info: Although SD video in NTSC land is 720x480, that 720 is often not "real" 720, but 704, and black for the rest, that's meant to be written off as overscan. Sometimes, the 704 you want isn't percectly centered, and that's what happened here. If Toei had bothered, they could have centered everything back in 2000 prior to any other editing. Since they didn't do that, they could have just adjusted the cropping whenever the picture moved. This alone wouldn't be perfect (as you couldn't do this with any fade transitions, and some position changes have superimposed text), but if I could clean most of that stuff up on the 60fps DVD raws, Toei could have done it here.
