Revealing mistake: When Iris is sitting in bed recording the message for Barry, she is holding her iPhone so that the start button is on the left side, but the "video record" button appears on the right. Additionally, her right hand covers the speaker area of the phone fully, including the front facing camera. It is impossible for Iris to be recording the video live and reveals that the video footage was recorded ahead of time. The illusion that the video is being recorded by Iris live is further ruined by the fact that the room lighting is turned off in the scene, but the recording is well lit. (00:02:55)
The Catwoman from Channel Six - S2-E12
Other mistake: When Irma finds April's Turtlecom and fortuitously contacts the Turtles, Leo answers the call and holds up the communicator in his right hand. The problem is that in the close-ups of Leo's open communicator, the animation of his wrist area is not complete, so his hand looks disembodied. Additionally, after Leonardo answers the Turtlecom call from Irma, she asks, "Who are you?" and in the next shot of the Turtlecom Irma is holding up, we see Raphael moving his lips as he says, "I'm Leonardo."
Continuity mistake: When Katara is trying to heal the wounded earthbender, she gives Sokka the idea to take down The Drill from the inside. Sokka then stops her from saying anything while she is sitting down, and she is wearing her necklace. When she stands up in that same shot, the necklace is gone, like they forgot to animate it. (00:07:35)
Continuity mistake: When Danny and Ward meet Joy in her new place, Ward says "who was it who said I was being childish?" Danny is in the background, holding the folder cover open with his left hand. Shot cuts as he speaks, and his hand's suddenly on the pages with the folder cover hanging down loose.
The Hand That Rocks the Mabel - S1-E4
Continuity mistake: When Mabel gets back from her date with Gideon, she finds Dipper reading the 3rd journal on the sofa. However, there is a 2 on the book instead of a 3. (00:06:08)
Other mistake: One of the natives putting the captured Seaview personnel into the cave is wearing laced up sneakers. (00:36:25)
Continuity mistake: Ashley Barrett is first seen behind Homelander, but then in the next shot she immediately jumps in front of him. (00:19:32)
Continuity mistake: When BB-8 hears the creature come up from the sand behind him, he stops. Just before he turns around the orange rectangles on the left side of his face to being almost all uniform in shape and size, to now having two big ones on the ends and two small ones in the middle. (00:00:30)
Beyond the Farthest Star - S1-E1
Other mistake: When showing Scotty on the bridge, some of the frames show more of his body than others. In those frames, you can see that he lacks legs.
Shelter from the Storm - S3-E18
Continuity mistake: When Winn and Brainy hug, Winn starts the hug with one arm high and one lower, towards Brainy's waist. The shot cuts and both his arms are up and in the centre of his body.
Episode XXIX - Couple on a Train - S3-E3
Continuity mistake: When Josephine grabs Ezekiel by his poncho, she is wearing a black glove on her right arm, but when the scene cuts to Ezekiel when he says, "What business is it of yours?", the glove disappears, showing Josephine's arm bare, but in the next shot, she is wearing both gloves again. (00:08:40)
Visible crew/equipment: During the final battle between Duncan and Luther, you can see a crew member holding a boom microphone pole standing on the stack of hay bales in one of the shots. (00:44:10)
