** Noticeable ADR. It's unavoidable that ADR is often used, especially in television, because sometimes audio doesn't always capture well during certain scenes and actors have to match the cadence used in a specific scene which can be difficult to achieve. Sometimes you can notice it, but you can easily ignore it. However, it's the very noticeable ones that are often the most distracting. It's in these moments where the re-recorded audio can be louder than the rest of the dialogue in the scene, which can take you out of the moment. Although unnecessary ADR is even more distracting. It's when they have the actors say a line that wasn't originally in the script/scene, but added in to further explain what is happening in a particular moment. It wouldn't irk me so much if it wasn't often used as a tool to explain to the audience what they can already figure out. Instead of having the camera focus on an object and have the character walk over to it and pick it up, the unnecessary ADR has them saying, "hmmm, look at this thing" playing over that moment. It doesn't always happen, but it's very, very noticeable when it does and it bothers me.
** Actors with empty cups. We've all noticed the fact that sometimes when actors is holding a cup that's supposedly filled with a drink, often a coffee cup, that it's very noticeable that there's nothing in it based on how they're carrying said cup. It would be nice if they actually had something in the cups. Not necessarily liquid, but just something to add weight to it so the actors aren't just carelessly flinging the cups around with their body language without taking into account that hey, yeah, you're supposed to sell the fact that you're holding a scolding hot cup of coffee.
** Reverse editing. This doesn't happen too often, but the things I've watched it's enough that I've noticed this far too much that it bugs me. This is where you have a scene that was filmed, and in post-production the editor decides to reverse a moment in filming. So, say, if an actor is facing the camera and is turning their head to the right, the editor will have the scene go from having them turned to the right and then looking towards the camera. These moments are often very split second and happen very quickly, usually in the middle of a conversation with another character or a transition of scenes, but it's hard to really ignore it when you can clearly tell that it's reversed. I can understand that they need to convey something with the narrative by having certain scenes constructed in a certain way, but it just looks so unnatural and unnerving.
** The Wilhelm Scream. I think it's just overused at this point. Yes, it's an insight joke and we're expected to hear it in some franchises (i.e. Star Wars). However, wen I'm watching a film and am totally engaged with it, and then they interject the Wilhelm scream in the middle of something totally serious, it takes me right out and it automatically makes me hate whoever approved of it.
** Replacing televised music with something else, or nothing at all. Although this one is more understandable given the whole royalty rights issues concerning music in television shows, it does bug me somewhat whenever I get a DVD of a show I liked only to find out that much of the music that I remembered being in the show has been replaced, or that there's no music featured in a particular scene at all. As someone who used to record a lot of shows back in the day onto VHS tapes and rewatched them on the regular, it can be quite jarring and disappointing when you get the official DVDs and none of the music you liked that was featured in many moments in the show are missing. This is something mild in comparison because, again, it's a rights issue and not all shows can secure those rights for one reason or another, but it still bums me out that some iconic moments made memorable through the music used in a show can be lost because of it.
What are some of your pet peeves when it comes to the technical parts of film/television?
