Screencasts or slidecasts (screen videos) give students the opportunity to watch the lecture or seminar content as often as they like and at their own pace, and to acquire the knowledge presented independently of lecture times and lecture theatres. This method is therefore ideal for self-study.
Detailed description
The creation of the screencasts or slidecasts involves synchronising a slide presentation with an additional audio recording. Based on a PowerPoint presentation on a defined topic, an instructional video was generated using the paid programme "Camtasia Studio".
For the Slide presentation it is advisable to prepare a script and a short storyboard. On the basis of these, pictures (e.g. with a digital camera) can be taken from practice. Your own pictures form the basis for the PowerPoint presentation. The examples used should be valid for as long as possible. Many animations can be included in the presentation in advance. However, it is also possible to generate animations later using the Camtasia programme, as the actual text is only available at this point.
The Soundtrack can be done with an external microphone (can be connected to a computer) and the Camtasia programme. It is possible to show personal recordings of the speaker in the video. It is advisable to practise the text beforehand (but not to read it out) in order to ensure that the speech flows as naturally as possible. Speaking slowly makes it easier to edit the audio sequences afterwards. If you have made a mistake, simply leave a longer pause so that you can easily see in the programme where you can cut out the sequence. The text should always match the image. The lecturer decides how long the individual slide is shown in the video and therefore has a great deal of creative freedom. Repetitions on the image and sound track are an advantage.
After the slide presentation has been set to music, the Processing with Camtasia (picture and sound track independent of each other). A variety of animations can be inserted into the picture track and unwanted words/sentences can be cut out of the sound track, for example. The finished video is then saved by Camtasia in various formats (e.g. MP4).
The Publication takes place on the moodle learning platform, but is also possible on YouTube, for example. Here you can see an excerpt of the finished instructional video as an example:
