It is neither hindered by highly random motion (such as the water-surface turbulence in a large waterfall), nor helped by the absence of motion (such as static landscape shot by tripod), which are two opposite extremes commonly used to test interframe video formats.

To keep file sizes and transfer rates under control, frame sizes and rates, along with sound sampling rates, are kept relatively low with very high levels of compression for each individual frame.
