You can use Poodll to collect a variety of multimedia that will be recorded (in your browser, using Flash) and embed directly into Moodle without tricky plugins or external sites/tools.
Poodll will allow you to collect a snapshot image from your webcam, record audio from your microphone, or record video (with audio from your webcam) directly from students in an assignment or by you anywhere in Moodle. You can even send along an image to be marked-up by students and then returned to you for assessment (whiteboard).
