Continuity mistake: Phoebe is going into the school in one scene, but as the camera moves she vanishes while on screen.
Visible crew/equipment: When Kel gets up to get more water you can see one of the cameras.
Continuity mistake: Ray places a donut that Debra throws at him on the third step and then stands up. Later the donut appears on the second step when Frank comes down the stairs. (00:19:15 - 00:20:45)
Not in the Line of Fire - S3-E15
Continuity mistake: When the vendor throws the hotdog at the press conference, a lot of the toppings/condiments trail behind it. When the shot changes and the hotdog hits Mike, there are no condiments trailing behind it. (00:19:10)
Blue Wants to Play a Game - S1-E12
Other mistake: The jigsaw puzzle Steve and Blue help Shovel and Pail with has a picture of everyone playing musical chairs from the Mailbox's Birthday episode, but Steve suddenly isn't in the puzzle. He played musical chairs, so he should've been in the puzzle.
Revealing mistake: In the scene with www.planetsolomon.com, you can see that it is a pre-filmed video (not a live stream as he said), as it has a time slider and play/pause controls etc. (00:13:05 - 00:13:45)
Suggested correction: During streaming, any video player can be used. Meaning "play" or "scroll" buttons are still visible, just not functional.
The color of non-functional buttons will be muted. You can see in the picture that the stop button is solid black, indicating that it is functional. The marker on the status bar is also partially advanced. In a live stream, the marker would remain at the beginning position unless someone paused the stream, in which case resuming play would cause the marker to advance in order to catch up to the delay. In this scene, Dr. Solomon is teaching his class and interacting with his students, meaning no-one paused the stream.
Midori no chikyû wa makasetoke - S1-E2
Other mistake: When Yurika restarts the Nadesico, one of the screens pop up with a huge congratulatory "SAFATY ROCK OFF." (00:18:05)
First Kiss - S1-E17
Visible crew/equipment: At the end of the episode when Harvey hops away, a boom mic is visible. (00:21:55)
