# Media File Size Overview

The tables below contain the median sizes of files taken by our SDKs. In 95% of cases, the mean sizes are comparable with median, but, in 5%, files might be significantly larger than expected.

The file size of the best shot, as the best shot is also a single frame, is equal to the file size of the **One shot** gesture.

For each gesture, you can see whether it counts as [passive or active Liveness](https://doc.ozforensics.com/oz-knowledge/general/readme/passive-and-active-liveness).
