A while back I posted about how I was occasionally finding lip sync lag (ala “Kung Fu Theater” when I recorded my on-camera video introductions and conclusions using Screencast-o-matic. No matter what I did, I would still experience some lag when recording my face, and my lips and words did not quite match up in the final video. They appeared to be out of sync by a couple of frames. I’ve since changed my process and have now removed the lag entirely.
I now use the Logitech Webcam Software to record my introductions. I use my webcam to record my video, but still use the Blue Yeti to record my voice, as the Logitech software allows you to choose a microphone source separate from the webcam. This keeps the audio levels consistent between the Logitech software and Screencast-o-matic records, so I don’t have to do much fiddling with audio in my movie editor.
Since I am editing my videos in Windows MovieMaker (yes, it still works!), the additional step in recording in Logitech doesn’t really take any additional time. After I record the Screencast-o-matic demonstration, I download the video file to my computer, and the file, along with the Logitech video file, into MovieMaker to edit.
