First thing I noticed when editing these videos was that just as important as the quality of the video taken is also the quality of the audio. Different people have different loudness to their voice, and the location and characteristics of the microphone matters. By default, most organizers would record the audio projected by the speakers. Unless if the audio characteristics of the room is perfect, I wonder if it's better to have a voice recorder placed at the speaker to have the clearest possible voice.
As regards the video itself, I’ve been a bit inspired by what these organizers did here:
Here, the captured video of the presentation is blurred out, and replaced with a high quality screen recording. I think this would be better in the sense of allowing the viewers to see both speaker and screen with both good quality. The key would be finding the right spot and keep the camera there without movement if possible during the talk. The videos overall are a bit dark, but I guess it’s true to form.
It’s something for me to think about next time.
Anyways, the first two talks are good introductions to the symposium as they talk about techniques and evolutions as more is known regarding anatomy and surgical considerations.
