@murdock_tm IIRC, Gridman is the first series from Tsuburaya that isn't film. IIRC, Tiga and the like did use a bunch of film, which the HD remasters used for a bunch of stuff. I'm not as well-versed in Ultra's video stuff as I am Sentai, Rider, and Metal Heroes.
HD raws for (most of ) Ultraman 80 are up. These are from a 2021 broadcast of the HD remasters. Episodes 22, 29, 30, and 48 are not included due to issues with the recording files.
HD raws for most of Jumborg Ace are up. These are from a broadcast on NECO several years ago. Episodes 24 and 28 are not included, as the recordings I have access to cut off half-way through those eps.
@Phantom245Power While improvement over the Madman Beast Wars DVDs would be mostly down to what BD has over DVD as a format, since those DVDs used the original D1 source.
@Phantom245Power Honestly, Star Trek TNG is the odd one out. Gurren Lagann (which got re-composited in progressive HD from the original digital elements) is the only comparable thing I know of.
