Abstract:

Teaching at the university is structured around theoretical classes, fundamentally expositive, and practical classes, where skills are learned and theoretical knowledge is applied. There are many ways to complement student learning in the classroom. Usually, notes, reference bibliography, the same slides that have been presented in class are provided for students to take their notes, etc.

Currently, our students, and teachers increasingly, consult audiovisual content on various platforms and social networks. Lists of links to videos or photos can be shared with students so that they can complement or expand their knowledge of the subject matter taught in the courses. However, many times these external contents, made by people who do not have to be teachers or qualified personnel, are very interesting, but may contain errors or not be properly adjusted to the subject.

The elaboration of training complements by recording with chroma (green or blue background) is exposed in this work. This type of background allows you to record in the office or at home and then add the desired background. The investigation is exemplified with a real video recorded using this technique on the construction process of a sloping roof with curved tiles.
