What exactly is an iPhone doing when it’s ‘Preparing’ to send a video?

184 views

I’ve noticed a lot since the newer iOSs that when you send a file it gets stuck on the ‘preparing’ screen for quite a while, even when the video is freshly recorded. I swear this didn’t use to be the case and it was decently fast. So what exactly is happening?

When you send a video over a network, you really can’t just send the whole video; that could be super dense, in terms of data, and take forever to send. To remedy this, your phone compresses the data into a much smaller representation of that same data. With newer devices, and more detailed cameras, there’s more data to process, which means compression will take longer (but will save more data).
