How to use audio and video
You can pre-record content or lectures and then upload them to a website or OWL course site. To do this, use a video camera to record your desired video. If you are recording lectures and have a good quality webcam with a recording suite, this may be a viable option for you. In terms of audio, most cameras allow for an external microphone to be attached, or you may use the camera's microphone to capture sound while recording. If you record your footage on an external camera, upload your footage to your computer. Most cameras will provide instruction on how to do this. When you are editing your footage, you can use a non-linear editing program on your computer. Video editing programs range in capability and complexity, but most systems are bundled with basic editing programs, such as Windows Live Movie Maker for Windows systems and iMovie for Mac OS X.
You can upload your finished videos to your OWL site in Resources and you then have to option to embed them as multimedia in an instance of the Lessons tool. Please note that individual files uploaded to OWL can not exceed 1 GB in size. You may need to check your video compression settings when exporting your video from your editing program. You may also upload videos to YouTube and then embed the link in your course. Another option for using audio and video in your course is to use a web conferencing interface which includes webcam and microphone support. Webcasting can add an interactive element as students may be able to ask questions or chat with teaching assistants and other students.
