For some context, it's because Indian movies were conventionally much longer in length (2.5 to 3 hours). Movies are written to have a cliffhanger at the interval, so much so that it's sometimes referred to as a meta joke.
SD cards don't perform wear leveling while ssds do. This is why there are specific SD cards meant for surveillance cameras. They have additional wear levelling circuitry at the expense of speed.
So photographers who fill up their sd cards end up writing over the same spots repeatedly and wear them out.
