I use these bits of technology to record my MOOC lectures:<\/p>\n

Ink2Go is an adequate product and draws nicely the but its poor hotkey support means that I cannot change colors with a mere keystroke or Wacom button and I need to have the Ink2Go menu in the lower left of the screen – which you can sometimes see on my later recordings – which makes the recordings look less professional.<\/p>\n Update:<\/strong> I am so disappointed with all of the screen-drawing products that I have started to build some of my slides using Reveal.JS and my own JavaScript-based screen drawing tool that I call DazzleSketch<\/a>. I am experimenting with this approach for my new book TCP\/IP Networking<\/a>.<\/p>\n TorchLED 50 Watt Light<\/a> – I use this to light my face a little bit – takes away shadows on people’s faces.<\/p>\n I record on a 4-CPU MacBook Pro 15 with an SSD drive – and it seems to labor a bit -I tried a recent 2-CPU MacBook 13 and it could not keep up. Camtasia does a great job of compressing the video without loss – but it is a bit CPU heavy. If you look the Camtasia files are surprisingly small and so easy to archive the original high quality materials instead of the rendered MP4 files.<\/p>\n The Logitech camera drivers for Mac are kind of weak and so the WebCam Settings tool is very important to adjust and fix color balance and turn off auto-focus to keep me from looking too blue or randomly changing colors and having the focus wander while I wave my hands.<\/p>\n I have derived some settings for the screen layout and came up via experiment with some compression settings for YouTube and for MP4’s that I make. I find that I need to make my files about 2X larger to keep them looking good on YouTube. In Camtasia when I export, to get good results I need the quality at the 3\/4 mark. But for just making files to be played with Quicktime or to keep for archive I export with Camtasia’s quality setting at the 1\/2 mark.<\/p>\n For very wide-screen videos with a big version of me on the right hand side that I produce for MOOC \/ Distance education like this:<\/p>\n
