General guideline for the framing of the fashion show video.
Frame the model as full body from head to toe (just enough spacing above the head and below the feet) when they come out and walk towards you. Smooth zoom to keep the framing of head to toe without excessive empty space above the head and below the feet.
About mid way, transition the framing from full body to 3/4 body (from head to mid thigh) and let the model walk a bit in this framing until stopping and posing. When they do their poses at the end, the framing will stay at about 3/4 from head to thigh.
For the walk back it is the reverse. Walk a bit in 3/4 body then transition to full body and continue to walk until exit or passing the upcoming model. Smooth transition from current model to next model.
In this video, the transition from full to 3/4 body needs to be more smooth.
3/4 body shoot in this video is slightly too tight. Cutting the head and cutting too high into the thigh.
The framing below is too wide. Model is too small in the frame.
Zoom in more to remove excess spaces above the head & below the feet.
The framing below is too zoomed in.
No need to zoom in this much to half the body. 3/4 body is the limit.
