Here’s a bit of a log of what I worked on:

Superman (aka the Mad Scientist): Fixed the “true justice” (or “truth justice”?), patching in voiceover from the Bosko audio.

Billion Dollar Limited and The Magnetic Telescope: entire videos use Bosko’s audio.

The Arctic Giant and Electric Earthquake: unchanged from Warner Bros. edition.

The Bulleteers, Japoteurs, Eleventh Hour, Destruction, Inc., Mummy Strikes, Underground World, Secret Agent: prologue uses Bosko Audio.

Showdown: prologue uses Bosko audio. “Streak of Lightning” etc. sequence uses Bosko video as well, as Warners video isn’t timed right (I think it’s taken from a different cartoon). The archive.org version has a police siren that plays when the bad Superman is on the roof and he looks over and sees the police cars pull up. That part is silent in the Bosko and Warner Bros. editions. I know there was an edition that added sound effects, so maybe the archive.org version is that one, but since I have two sources that agree, I’m using the silent version.

Eleventh Hour and Jungle drums have entirely the wrong opening sequences. They now use Bosko’s audio. I was able to cut up parts of the video to keep from having to use much of Bosko’s video, as the colors are way washed out (especially the reds on the Superman logo).

In Eleventh Hour, when the film’s main sequence starts, the Warner Bros. version cuts out several frames and fades in the music too late. I would normally here use the Bosko video, but that set superimposes a title over the start of the video with the date it was released, so there are a few seconds that use lower-quality from the archive.org set. It transitions back pretty quickly and I’m fairly happy with where I hid the change.

All shorts except Superman, The Arctic Giant, and Electric Earthquake use Bosko’s audio for the ending sequence. The Warner Bros. set in the other 14 shorts will fade out the music abruptly and then throws in a musical tag over the Paramount logo. Usually I make the soundtrack switch when the scene changes back to Lois and Clark for the epilogue.
