Quoted from PinMonk:It was weird, like the lights were off in the room in the video and there were just some Christmas lights on in the back. It got lighter toward the end. No idea what's up with that.
Here's whats up with what you saw.
This mode has the 4 main villains escaping out of jail and you need to round them back up. The earlier code used the animated cartoon style clips but for this code they switched to video clips from the show to show the breakout from Gotham penitentiary. The only video clips that have all 4 villains together was from the second to last episode in season 3 called "The Entrancing Dr. Cassandra" starring Ida Lupino as Dr Cassandra Spellcraft. Interesting fact: Ida was not only a movie star from the golden age of Hollywood but also the only female in the 50's who also produced and directed major films. She was the forst woman to direct a film noir, "The Hitch-Hiker".
In this episode Dr Cassandra and he husband come up with some invisibility pills. Their plan is to release all the Gotham super villains and also give them the invisibility pills so they can wreck havoc on Gotham. There is a brief clip where 6 major villains are shown escaping. they are Joker, Riddler, Catwoman, Penguin, Egghead and King Tut. By season 3 the ratings were dropping and the budgets were slashed so they cut as many corners as possible. In this case they saved money by having all the villains be played by stunt doubles not the actual actors. An interesting note is that Eartha Kitt was playing Catwoman in season 3 but for this episode the Catwoman double is someone picked to look like Julie Newmar instead.

Not only were they too cheap to use the real actors (or even have any henchmen in this episode) they also had no budget to do the actual choreography for the big the fight scene with all the villains. So they improvised and decided to have all the villains take the invisibility potion first. This way Batman, Robin, and Batgirl are fighting invisible people.

The heroic trio don't do so well fighting invisible villains so they decide to even the odd by turning all the lights out. So half the fight is in the dark and all you see are some random lights in the background. That's what you are seeing in the video clip on the LCD during this mode. Here's a you tube clip where you can see it as it appeared in the show.
Here's what the writer, Stanley Ralph Ross, said about the episode:
“The producers ran over budget on this episode, and they could not afford to take the two days necessary to block and shoot the fight scenes. So, I wrote this episode in such a way that the fight was in the dark; therefore, the episode was shot in less time."
Here's a link to watch the whole fight from the beginning.
Looks like we definitely have batgirl in the game now, at least a little bit. Maybe in a future code update the video for this mode can be fixed. They could just get better close up shots of the villains from other episode fights and splice them together. Or maybe use clips from the movie (might not happen if they don't have rights to movie though). If Stern doesn't do it, someone could fix it with better clips via pinball browser.
