All the Golden Collection Volume 1 prints exist in SD format only, except for Fast & Furry-Ous (you can tell because the Platinum Collection Volume 1 Blu-Ray print of this short is the exact same brightly colored, heavily-abused DVNRed restored transfer with heavily-DNRed audio as seen in Golden Collection Volume 1). Same goes for the the I Love Tweety Japanese DVD prints, and the 1997/1998 dubbed versions. http://kimcartoon.me/Cartoon/Looney...lume-1/Episode-21-Fast-and-Furry-Ous?id=63281 All the Golden Collection Volume 2 prints onward do have a HD master, and therefore exist in both SD and HD formats. The SD formats were used for the Golden Collection DVD releases. However, for some shorts on Looney Tunes Platinum Collection: Volume 3 Blu-Ray/DVD that were previously released from Golden Collection Volume 2 and 3 were re-restored even though their previous Golden Collection master does exist in HD for reasons unknown, and more often, the new restoration appears to have a much darker color. Examples include Little Red Riding Rabbit, A Corny Concerto, Gorilla My Dreams, The Big Snooze, Slick Hare and Walky Talky Hawky.
