As frame sizes continue expanding to equal a living room wall, the accompanying file sizes explode as well.

This chart in this screen shot illustrates how quickly file sizes increase with frame size.

NOTE: This table is based on ProRes 422, at two frame rates: 24 fps and 60 fps. Shooting raw or log files would increase these file sizes about 2X.

Here are the source numbers for this chart.
