Equipment SeenIn the scene after Trish & Dez dance, the four stands in front of the counter, when you look by the metal door frames, you can see the shadow of the boom mic. (Refer to the picture on the left.)
In the scene where Austin & Ally are thinking of some ideas for the song, you can see that Austin's necklace keeps changing position, form being behind his blazers to a part of it over the left collar.
Continuous ErrorDuring the scene after Lester Dawson leaves the store to a Accordion convention, Ally tells a man that "No, this isn't the eye doctor". The man turns and knocks over two cymbal stands. After the next shot, it only shows one cymbal standing.
After Trish makes her entrance with her yo-yo's, you can clearly see that the cymbal stand is still standing. They must have shot this scene before they shot the scene where the man clearly knocks over the cymbals.
But in the next following scenes, you can see that it is knocked over. There are many shots after these where the cymbals keep changing from a standing position to where it lays on the floor. This is not the only episode where instruments keep changing position. This kind of mistakes are common especially if editing wasn't checked carefully.
Ally complains about stepping in kangaroo poop, but when you see where she was standing, there was no poop.
Continuous ErrorBefore Austin performs in the store, Ally, Trish and Dez come out of the door on the second floor. In one shot, it shows Trish running out of the door followed by Dez. But in the following shot, it shows Ally behind Trish followed by Dez.
Equipment SeenIn the scene where Austin is performing "A Billion Hits", you can see in the upper right corner by the window a white colored reflection. It is actually the reflection of the wall. In the picture, you can see the reflection of the camera.
Trish is laughing at Dez being beat up by the kangaroo. When Dez is actually shown, he is actually not being hit by the kangaroo. The same thing happens when Team Austin is watching Lester Dawson. He is actually not being hit by the kangaroo.
When Ally first showed which book she had to read, it was completely black. When Ally tells Austin to read the book, and gives it to him, it has gold writing on it.
When Austin asks if he and Dez are the only people who are worried for his career, he said "Me and Dez" when the correct grammar would be "Dez and I".
In the first scene, it shows the rack of violins have collapsed. In the following shot, when Trish enters the store, you can see the bottom rack of the violins shelf isn't collapsed.
Continuous ErrorIn the scene before Nelson enters the store with the piano, you can see three music stands, different colored, standing by the cymbals.
After Nelson leaves, the three music stands get moved but no one seemed to have touched it.
ErrorDuring the scene where Ally is talking about Dallas, there is a camera on a tripod, which means it has to stay still. But when it shows the Jumbotron, the camera seems to be moving but it shouldn't move since it is mounted on a tripod. (You need to see the video from the episode in order to watch the moving camera on the jumbotron.)
Continuous ErrorAfter the scene where Trish enters the store in her Cheese costume, you can see a shot of Ally that a man in pink is sitting on a table behind. But after that very shot, you see the man in pink walk behind Austin, Dez and Trish. This is a continuous error since it is impossible that he has walked quite a distance in a second.
When Ally is about to fire Dallas, depending on who's talking, there is either one cymbal or two.
When Austin hugs Ally the first time, he has a book in his left hand, and then when the camera changed perspective, the book was gone.
