Audio problem: When the kid drinking beer says, "Get me another one babe," his mouth says "bitch," not babe. (00:50:50)
Audio problem: When Holmwood has the gun pointed in Van Helsing's face in Lucy's crypt, Van Helsing explains about the undead. Switch to a shot behind Helsing and his jaw is still moving even though he has stopped speaking. (01:25:35)
Audio problem: When Jafar is coming out of his hiding place to talk to Jasmine, he opens the sliding wall only about a foot. When he shuts it again, you can hear it sliding shut for a very long time!
Audio problem: The ghost of Christmas past says "these are but shadows... they are what they are - do not blame me." Her mouth keeps moving after she stops speaking.
Suggested correction: No, it doesn't. When she finishes this speech at 45:16, there is an immediate cut to Scrooge. We can only see the back of the ghost. Her mouth is not visible.
Suggested correction: A mouth can move without speaking, not an audio problem but a puppeteering problem that is not a mistake.
A puppeteer problem would still be a mistake.
Maybe for the puppeteer, but in the movie it is no problem because a mouth can move without sound coming out. So what exactly went wrong?
But practically speaking people (or puppets) don't just flap their mouth open and closed with no reason. The overwhelming probability is simply that there was a dubbing error or a line was cut and the dialogue didn't fit with the mouth movement.
The mouth opens 1 extra time. That's all.
But it's glaring enough to be noticeable. Regardless of how or why it happened, it's a mistake.
In the version on Disney+, there is an immediate cut to Scrooge as the spirit finishes her speech. We only see the back of the spirit's head. Are you seeing something different on other versions?
https://www.youtube.com/watch?v=hBDqCFyugW0. I got the scene right here, it's at 1:50. Judge for yourself. I can repeat that part over and over again, but to be honest, sometimes it looks like there is an extra movement. Sometimes I can't see it. Even if it was, muppets move their mouths without speaking all the time.
Audio problem: When Joey is awakened from her dream about her father's death, she picks up her phone, but the sound effect of her phone being pulled off the base doesn't quite match. (It plays the sound of the receiver fully being picked up before it's fully picked up.)
Audio problem: At the police station, Helen and Jake are talking. When the camera is on Jake, Helen says her lines but her mouth and the words are out of sync.
Audio problem: In Las Vegas, before the yellow car scene Nick says "we have to jump", but his mouth isn't moving.
