For your own videos that nobody ever even wants to watch again, you surely don't have. For the servers for your business...

Well... I can imagine there are enough people who won't care too.

Note that the chance for corruptions increases as long as the data remain in RAM unsaved and only much later get to be saved. We are lucky that, at least in private use, we typically copy the data to the medium without keeping it too long only in the RAM (order of seconds or less). So that also reduces the chances of our pictures being saved with the wrong bits.

An important tenet of the digital world is avoiding error propagation. You pass the video along a few times and the errors accumulate.
