This software turns my MacBook Pro into an AirPlay receiver enabling iPad recording and projection.
BEST WAY TO RECORD LECTURES ON MAC LICENSE
The main software element is Air Server for macOS (the license cost is $11.99). To capture audio, I depend on rather inexpensive Blue Snowflake USB Microphone, which provides much better sound quality sound than the MacBooks' built-it mic. Because we can easily record or broadcast laptop’s screen, effectively we can record/broadcast the iPad’s screen. In screen mirroring, whatever action you take on iPad the result is visible in the server application running on the laptop. Both devices are connected via WiFi or USB network. I am using built-in Apple AirPlay protocol to mirror iPad’s screen to the AirPlay server running on my MacBook Pro (more about it in the Software section below). This is where AirPlay and MacBook come into play. However, iPad has one important limitation: projecting to a beamer while recording screen and audio are currently impossible to do directly. In fact, I find writing on iPad much more convenient than on a white-board, with the added value that you never have to erase one content to make space for the other (more about it in the Software section below). The current resolution of iPads is close to that of a paper sheet, enabling seamless handwriting in good resolution. The key element is Apple iPad Pro with Apple Pencil. To record the audio I am using an external USB mic connected to the laptop. The laptop records the screen of the iPad and my voice/face, and it takes care of projecting the screen to a classroom beamer through HDMI, or whatever other port is available. The iPad is connected to my MacBook Pro (however, any other computer that is able to act as a fully-capable AirPlay receiver will do). The main idea is simple (TL DR): I am usingġ2.9-inch Apple iPad Pro, coupled with Apple Pencil, from which I can project slides, do hand writing (essentially think of it as a digital white-board or an overhead projector) or browse web, etc. In other words, no distractions just the essence.īelow I provide description of the setup, with a disclaimer that it is based on Apple hardware and some non-free software tools. In this setup, only lecture content is recorded (i.e., slides, board and of course voice, optionally my face) and not the entire classroom, as is the case in camcorder-based solution. Last semester I switched to a new setup, that effectively gives me complete control over how I deliver content (slides, hand-writing, live coding, etc.) while allowing me to record video and audio in HD. I should note that UB provides classrooms that have built-in hardware for video-recording (that records automatically for you), however, from my perspective the issue of quality remains. However, this setup had one advantage: switching between, slides and black-/white-board was essentially seamless, giving me flexibility in how I deliver my content. The solution was very suboptimal: it required someone to operate camcorder, and video quality was not the best, especially when a classroom was dim. Additionally, it gives me the ability to review my lectures for potential improvements.įor a very long time my recording setup was based on a camcorder with a wireless mic transmitter/receiver. At the same time, it gives students flexibility in reviewing lectures on-demand, and at the pace they find comfortable. Contrary to some opinions, posting lecture videos does not decrease in-class attendance (and no – I am not enforcing attendance in any way, say, by sign-in sheets). One technique that I found highly effective when teaching, is recording all my lectures, and making lecture videos available to students almost immediately after the class (UB provides Panopto to students and faculty). Index Simple Setup for Lectures Recording MotivationĪt University at Buffalo (UB) I regularly offer a set of somewhat diverse courses: CSE 470/570, BMI503, BMI577/CSE577.
