I picked up 2 Toei video discs in my last haul and its amazing how many chapters there are.
Below are the 3 that I know I own that have massive amounts of chapters.

Golden Bat (1966) [LSTD01051] 41 chapters for a 73 minute
film plus 12 minute special at the end of disc.

Cyborg 009: The Movie (1966) [LSTD01168] 70 chapters for a 68 minute film.

Cyborg 009: Underground Duel (1967) [LSTD01175] 64 chapters for a 60 minute film.

I know I have other Toei discs but can't remember so many chapters on any other type of LDs.
Anybody have an explanation to why these have so many chapters????
Every minute more or less.

Just checked and my Inazuman discs do have a bunch of chapters, Zubat has even more and Green Slime doesn't have that many, about 20

I have Gold Bat. I’ll check it out to see if the chapters make any sense to me.

I haven't watched it yet but saw it on the second Cyborg film so many chapters.

I do have those GE999 special discs and I think they are around 25 each disc, still sort of a lot I think.
Zubat has about 38 per disc, again I feel its sort of a lot when usually TV shows only have 4 chapters each episode, credits, middle end.

Just seems overboard on those Cyborg 009 films, some are only every 40 seconds, wonder if its due to the isolated soundtrack???

Perhaps, but I don’t think so. It’s possible their mastering kit auto generated chapter stops at a set interval and they never moved it off default.

I watched Gold Bat again tonight. I like it now more than I remember liking it before.

Due to recent equipment failures and/or battery shortages I’m not able to select the analog soundtrack but the digital works this way. R is just the music and L is the music plus all the other parts of the mix (or it’s the opposite, whatever). Usually when this is the case the analog is the same as the digital, with the point being to not lock out people with analog only players. The movie is mono anyway. It is a bit annoying though because you pretty much have to manually select a single audio track, one or the other, every time you see a movie.

So when a new piece of music begins, that’s a chapter stop. If you are listening to just the music then you will have dead air between music tracks. This makes for some chapter stops that are less than perfect but they are relatively evenly spaced so it’s a decent way to get through the movie.

70 chapters for 68 min (009) seems a little crazy. It’s possible though that the way they did the soundtrack is different. Gold Bat is more or less perfectly synced between left and right, although it isn’t perfectly in phase all the time. If they did it differently, where the isolated soundtrack doesn’t sync with the full mix at all (Project A Ko Dual Disc) and the soundtrack had sound FX or lines from voice actors, that could account for the crazy number of tracks.

Yes its very annoying and that's why I sometimes search out discs that I need especially from Toei that I get the early versions not remastered.

Every time you play you do have to select the correct audio that you are wanting and if you forget that these have the iso soundtracks then you are sol.

I'll check my Cyborg discs to see if the chapters are connected to the soundtracks.

You're right!

I noticed that on some of the TOEI's Dragon Ball (Z) LDs I own: the chapters are actually the music tracks (often corresponding to some specific action scenes on screen).

Other exotic cases I've seen are chapters every 5 minutes, regardless of contents.
