Classroom lecture recording refers to the activity of recording a lecture with the help of electronic media devices like video cameras and microphones. This is a relatively modern concept devised to record the classroom experience in the form of electronic footage. The recording is accessible by the attendant of the lecture or even by someone absent from the classroom. The electronic video lectures can be shared easily and repeatedly revisited for reference and notes.
Many new classrooms and lecture halls are being outfitted with this revolutionary technology around the globe. Many lecturers and students believe that this technology has the potential to revolutionize the education system, making it better and more comprehensive. But before we start recording a classroom lecture, some key features should be included and arranged:
- Video recording equipment
- Sound recording equipment
- A tripod assembly
- Post recording editing software
Let us take a look at all the prerequisites beforehand.
Screen recording – Screen recording refers to the recording of the content on the screen of the person delivering the lecture. It is an effective way of capturing the presentation, videos and pictures displayed in the course of the lecture. These features make the recorded video more engaging and interesting for the students. For real time screen recording, specialized software is needed to be installed in the PC or laptop used during the presentation. The software is supported by all types of operating systems and major computer manufacturing brands.
Sound recording – This feature deals with the audio capturing of the lecturer’s voice and the interactive sounds of the video, audio or presentation used during the lecture. This is done with the help of special voice recording devices for lectures. These recording devices can be in the form of handheld microphones, table top micro phones or strap on microphones. The microphones should have high quality sound recording, so that it is easy for the listener to distinguish the voice of the speaker from the noise of the hall, when they replay the recording at a later stage. To achieve precisely this, noise cancellation filters are installed on to the microphones and the recording equipment. There are even some high end video cameras that have an inbuilt high quality sound recording microphone to record the sound in very high detail.
Video recording – This process deals with visual recording of the entire lecture with the help of special video recording classroom lectures devices like video cameras. The video camera is generally supported by a tripod assembly and can be manned or unmanned. The video camera must capture the entire range of the speaker’s movement, to make sure the lecturer does not go out of the camera’s field of view. The picture quality of the camera should be at least descent; this allows the person reviewing the video recording to clearly make out the points, stressed on by the lecturer. It also enables the viewer to clearly see the writing board or presentation used by the lecturer.
After the video recording of the lecture is completed, the recording is processed using editing and finishing software before it is finally made available to the students.
