How to make massive open online courses, can you teach me?

How to make a large-scale open online course? After watching the massive open online course for many times, I finally got a chance to understand the production process of the massive open online course for Desheng Zhizhi, and then I got the most authentic feeling about the massive open online course through my personal experience: the film-level blockbuster effect, the teacher talking to the camera Kan Kan, and various light and shadow effects emerged one after another, which completely broke everyone's previous impression that the online course was rough and poorly made.

1, preparation for large-scale open online courses

The recording of MOOCW was completed with the cooperation of many people, including photography and lighting directors. The content of recording and shooting has two parts, the first is the recording of the course, and the second is the recording of the propaganda film.

2. The recording process of large-scale open online courses

Next is the key point, the teacher's course recording process record:

In the recording and broadcasting room of Deshengzhi class, teachers and staff are already preparing to record the new class, and makeup artists are making up the makeup for the teachers. An assistant debugs the equipment, and two cameras supervise the shooting of the picture. The equipment in the studio includes: four overhead lights, two tracking lights, two side lights and two cameras. The main camera is Sony Full HD camera (mainly responsible for shooting the whole process), and the auxiliary camera is Sony EX280 (mainly responsible for supplementing the picture), two bee microphones, a 70-inch large-screen display (similar to the function of reminding) and a green screen (to prepare for the later matting).

When the teacher is in class, he faces the camera and controls the rhythm of the lecture through the monitor. The cameraman always pays attention to the screen, prompts the teacher's state, and ensures that the picture is natural and complete. After recording, it is the process of editing. Editors should choose and distinguish the recorded content, and use mainstream clip packaging: AE, 3D, Premier, etc. Due to the short course time of large-scale open online courses, editors need to diversify the courses according to the knowledge points. At the same time, in the biochemistry course, 3D models are needed to show the knowledge points more intuitively, which is also the later packaging.

3. Post-production in massive open online course

During the whole recording process, the cameraman never left the camera's display screen, so he was very strict with the pictures in the picture. Even a small stain on the background should be cleaned before shooting.

In addition to editing videos, editors should also add special effects to enrich the picture. Large-scale open online courses need to be particularly detailed and piecemeal. There is a break in editing, so we need to add some small animations to make the connection smoother.
