All, I have some on-line resources on my YouTube channel Introduction to Geotechnical Engineering (https://www.youtube.com/channel/UCyt3w3SogxUSJ7RSxQusXXA) which you may find useful. While there aren't actual labs recorded here there are lab prep videos and some lab animations. I don't have a nice front end for the channel, but it is organized into playlists by chapters of Coduto,Yeung & Kitch (2011).
Chris, I use a combination of PowerPoint, Camtasia, and Doceri. PowerPoint is for text, and basic figures. Sometimes I use the animation tools in PP but that's really time consuming. Doceri is a great digital whiteboard tool for the iPad. It's my favorite table tool and it's only $20 for a license. Camtasia I use for capturing screen video and the final editing of the webcasts. I just use a mid-range headset with boom mic, nothing fancy. It's really the compostion and getting the pedagogy right for the students that's the key. The audio and video just have to be good enough. Most student now are watching on their phones or a tablet. Doesn't have to be HD or anything.
Bill - I agree with Chris, your videos are super good quality. Quite the laborious setup, I am glad many will be using them and the gratitude will multiply. I sent you a request for the lab data via email, since now we need to have the student do some data reduction/interpretation, not touch the soil, but massage the data. :)
