Hi. I’ve gone through a lot of this and now I’m making short lesson videos for my A Level students.
A lot depends on your style, so try to understand that. I’m going for instructional lessons that go over the key learning points in the way I want them. I haven’t gotten on to demos yet.
My main tip came from my wife as she listened to me: sound interesting. I try to do this by writing a script and then recording the audio separately from the video. It is time consuming, but let’s me focus on content in the script, then on enunciation, energy and enjoyment in the recording. I record this using Quicktime through a Scarlett pre-amp. Use a strong voice and a pop filter to dramatically improve sound quality.
At the start and end of every video I do a short bit to the camera. I used to use my iPhone, then when I changed to my OMD camera, I was amazed how much better (and real) I looked.
I import these into Final Cut Pro, which can synchronise them. I also use RX7 to denoise the audio (and a couple of other filters).
I then play this at half speed. I have my slides in Explain Everything on my iPad and annotate the slides etc whilst listening to the recording.
I then import that to Final Cut Pro, tidy up and it’s done.
A lengthy process to be sure, but I like the output, which I plan to use in a flipped classroom for years to come, so it’s worth the investment to me.
