Camera technique for streaming is simple. Generally speaking the rules come down to
Camera work for streaming is not the same as for television. TV production uses a lot of movement and fast switching between cameras, long shots and lots of zooms/pans. However when streaming these techiques deteriorate the quality of the video output. This is because there is a finite amount of data available in a stream to 'redraw' the image, so the more that needs to be redrawn the lower the quality of the image. Also, while a long shot might look good on television, if you are looking at a video window which is about 6cm across, any small detail will not be seen.
So, the camera crew need to learn that camera work for streaming is a special technique and one that is not very exciting. Camera should always be on tripods with minimal physical contact from the camera operator. Shots should be tight, and there should be a strict rule for no pans or zooms.
If there is a video projector (data projector/beamer) being used (eg. for presentations) then there is a temptation to use a scan converter to input the video data directly into the stream (perhaps via a video mixer). However, often this doesn't give good results as the text used on some presentations is just too small to read. If the presenter is showing images, a scan converter works well, however if there is a lot of text it is sometimes more effective to point a camera at the projection. If this is the case then the camera operator has to be thinking about what the presenter is talking about and which part of the projection to shoot.
