Microphone benchmarking

 
Below is a video originally recorded for Georgi Radulov to demonstrate the effect of different microphones:

 

Camera benchmarking

For these lectures we will use both the Panasonic and logitech cameras. They are compared in the videos below and in this file:  Image Camera Comparison (and at the bottom of this section) are a summary of results and conclusions.

In the videos below, the Panasonic camera is always on the right and the Logitech on the left.

  • Low ambient light
  • Panasonic manual exposure, 50% horizontal crop, optical zoom
  • Logitech auto exposure, 50% horizontal crop, electronic zoom

 

 


Cambench3

  • Low ambient light
  • Panasonic manual exposure, 87.5% horizontal crop, optical zoom
  • Logitech auto exposure, 87.5% horizontal crop, electronic zoom

 


Cambench2

  • Studio lights
  • Panasonic auto exposure, 50% horizontal crop, optical zoom
  • Logitech auto exposure, 50% horizontal crop, electronic zoom

 


Cambench1

  • Studio lights
  • Panasonic auto exposure, 50% horizontal crop, no zoom
  • Logitech auto exposure, 50% horizontal crop, no zoom

  • CamBench4:
    • Low ambient light
    • Panasonic manual exposure, 50% horizontal crop, optical zoom
    • Logitech auto exposure, 50% horizontal crop, electronic zoom
  • CamBench3:
    • Low ambient light
    • Panasonic manual exposure, 87.5% horizontal crop, optical zoom
    • Logitech auto exposure, 87.5% horizontal crop, electronic zoom
  • CamBench2:
    • Studio lights
    • Panasonic auto exposure, 50% horizontal crop, optical zoom
    • Logitech auto exposure, 50% horizontal crop, electronic zoom
  • CamBench1:
    • Studio lights
    • Panasonic auto exposure, 50% horizontal crop, no zoom
    • Logitech auto exposure, 50% horizontal crop, no zoom

Conclusions:

  • Never use electronic zoom on Logitech camera
  • If zoom is needed, cropping in OBS gives much better quality
  • Studio lights improve noise reduction artefacts in Logitech
  • Panasonic is much more consistent quality and much more flexible w.r.t. zoom, exposure, lighting
  • With proper light and no zoom, the Logitech quality is sufficiently close to the Panasonic to replace it for video lectures
