Analysis

Highlight faces detected in three different frames:

In[6]:=
HighlightImage[#, FindFaces] & /@ VideoFrameList[ResourceData[\!\(\* TagBox["\"\<Sample Video: Friends at the Beach\>\"", #& , BoxID -> "ResourceTag-Sample Video: Friends at the Beach-Input", AutoDelete->True]\)], 3]
Out[6]=

Find faces over the entire video:

In[7]:=
tseries = VideoMapTimeSeries[Length[FindFaces[#Image]] &, ResourceData[\!\(\* TagBox["\"\<Sample Video: Friends at the Beach\>\"", #& , BoxID -> "ResourceTag-Sample Video: Friends at the Beach-Input", AutoDelete->True]\)]]
Out[8]=

Plot the number of faces found over time:
