![]() I first record and edit my own copy of the lectures and publish them on YouTube with CC-BY and then when we move a course to Coursera we re-record the videos using the University of Michigan style. ![]() I don’t show any video of me during demos but I add music and the picture / web site slide at the end of each video to tie back to my web site. Watch from here to the end to see how I wrap up a video.įor demonstration videos I do everything 720P with full screen on the demo to maximize readability. In the last few seconds, I slip in some music and then add a slide at the end with a picture and pointer to my course web site and bring the music up full. I like full screen video towards the end as I wrap up. If I am going to get philosophical or make a mini speech I take the video full screen. If the slide has material that I want the students to really focus on, I make the slide full screen. In terms of shot selection, if I have powerpoint that is low complexity and I will be weaving a story I like split screen. I always use free / no attribution music available on the YouTube Audio Library – I prefer no acknowledgement required music and then I add an acknowledgment :) I switch between several views depending on the content. I edit everything on the Mac using Final Cut Pro. If Ink2Go cannot scribble on PowerPoint slides I use the built-in pen for PowerPoint – which is horrible – the lines are too thin and cannot be adjusted and colors cannot be changed with a hot key. ![]() Ink2Go insists on leaving its UI somewhere on the screen – which is frustrating. I want to be able to select a pen, change its color, and clear the screen all with keystrokes that I can program into the Wacom. Scribbling Software: My preference is OmniDazzle, but it is no longer available and each upgrade of MacOS/X breaks it in a different way. Screen Recording: Quicktime on the Mac – I always record in 720p resolution so the fonts and top nav bar are as visible as they can be. Monitor: Wacom Cintiq 13HD – Allows me to scribble on the text I bought plug-in adapters because I did not want to mess with rechargeable lights. I set up the lights in a three point setup with the key light above and to the left of my camera. With the softbox you can have the lights pretty close to you without weird shadows. The Softbox and ability to dim are both very important features because otherwise the shadows are very harsh. Also if a little outside light leaks in – it blends better with daylight balanced lights. If you want to soften your color balance – do it in post production. You need daylight balanced lights (blueish) because the cameras get their best video with these lights. Some of my previous approaches to audio include (1) Audio-Technica ATR3350 with a 3.5mm mono to 3.5mm stereo adapter so the camera records the mono microphone to both channels to avoid a time consuming step in post or (2) just use the built-in Macintosh microphone, or (3) when I got tired of taking my microphone on and off when I need to get up and walk around I used a (very expensive) Sennheiser Omni-directional Wireless Lavalier Microphone. I still use the built in Mac microphone for streaming and for screen recording – because its noise processing is better than my shotgun mic, camcorder or Final Cut pro. But since I use Final Cut Pro anyways – the built in noise filter does a *really good job* cleaning up the noise. I have done some experimentation with several mics of various brands and they all have too much noise during silent periods that is exacerbated because my camcorder has auto gain control. My most recent audio setup uses an inexpensive shotgun microphone connected using a microphone arm. Set the camera’s “Micref level” to “Low” on the camcorder to avoid automatic gain control – and adjust audio in FCP/X. I have used various technologies over time, but this is my current setup: ![]() I am often asked how I record and produce my MOOC lectures. ![]()
