When Cat bounces up to Beck and is talking to him, you can see André and Robbie walk around the corner towards Tori, however, when the camera cuts to Tori, they come around the corner again.
When Jade throws her bent scissors to the "Instrument Use is a Privilege" sign, it disappears in the wide-shot but reappears when André is writing the chorus.
During the scene where Tori is acting like Jade, the position of the pillows keep switching around.
André said the name Jade was in the song "like 10 times" and Tori said to change the name to "baby." When he sang the song, he only sang "baby" 4 times.
