>>212708888>The biggest problem is simply people mumbling lines.This. It's ridiculous. Unironically one of the pitfalls of better technology.
>>212708556 (OP)Basically, mics used to be shit. And sound mixing was shit in the analogue age. So you had to position right next to the actor and the actor had to speak loudly and clearly. Naturally, Shakespeare-trained actors (and theatre veterans in general) excelled because it's a similar technique to talking for the stage.
However, it's very unnatural-sounding. People don't speak like that in real life. So when technology got better, actors like Tom Cruise came along who would whisper-shout a lot of lines. This type of speaking used to be way too quiet but now the mics could pick it up and it carried a lot of emotion in a subtler way. To cut a long story short, more and more actors were able to speak closer and closer to natural intonations.
The problem is that this meant they could mumble their lines and the mic would still pick it up.
>why doesn't the director/editor catch it?Because it's a lot easier to hear something when you know what you're listening for. And you lose perspective quickly. So they don't realise that they only comprehend the actors because they've read the script and seen the same line performed 20 times previously.
