The part that is also usually glossed over is how exploitative the production is (low pay/awful hours), even if it’s sometimes self-inflicted.
Not just knowledge but personal connections for favors. “Hey, [talented editor] it’s [famous DP], do you think you could tame a crack at this scene in your spare time? I’m trying to make something out of nothing and I’m positive you’ve got the chops.”
I don’t think anyone could reasonably call any of the exploitation self-inflicted. You have to take shit work a lot of times because a) nothing else is available and you still need to eat, or b) that’s the only way to get your foot in the door for the chance of being slightly less exploited. Unfortunately the industry collapsed when I graduated school as a career switcher getting into Houdini simulations. The software skill set is utterly devalued on the open market. I couldn’t get exploited if I wanted to. Now I’m a union tradesman. ¯\_(ツ)_/¯
The self-inflicted comment is a bit tongue in cheek because they do it to their own production to effectively “crunch” (to use video game parlance) but they also crunch themselves in the process. Difference is they have way more to gain. The sound mixer on an indie darling isn’t getting much out of it.
