This research aims to determine the form of the development of learning videos on the subject matter of oxidation reduction reactions (redox) with the help of wondershare filmora software so that they can become effective media in the learning process and to determine their feasibility. The procedure taken to produce the product is divided into 4 stages, namely: (1) determining the material to be developed, (2) carrying out design and development, (3) producing wondershare filmora software or packaging learning videos, and (4) conducting a formative evaluation and revise development product. The results of the assessment from material experts and media experts on the feasibility of this learning video have a very good category with an overall ideal percentage of 84,69% each in terms of the material presented and 90.5% in terms of the media displayed. The results of the peer reviewer test assessment of this learning video is 80,9% with a very good category. As for the results of the assessment of student responses to this learning, it is included in the very good category with an ideal percentage of 97.25% for small group trials and 98.75% for large group trials, respectively.  Keywords: Development, Learning Video, Wondershare Filmora, Oxidation Reduction Reaction

The purpose of this research is to determine the ability of subject teachers in developing learning tools in the independent curriculum. The results showed that as many as 40% of teachers were proficient and 60% of teachers were very proficient in carrying out or modifying learning objectives. As many as 40% are in the poor category, namely subject teachers who have not shown understanding in understanding the concept of teaching modules, and have not been able to modify teaching modules properly according to the goals, needs, and characteristics of the school. A total of 20% were in the sufficient category, namely, the subject teachers were quite good at understanding the concept of the teaching module, and were able to modify the teaching module following the objectives, needs, and characteristics of the school but still needed intensive guidance from resource persons. While 0% are in the advanced category, namely subject teachers understand the concept of teaching modules and are able to modify teaching modules properly according to the goals, needs, and characteristics of the school, but in some aspects, they still need resource guidance, for very advanced category 0% are subject teachers really understand the concept of teaching modules and can modify teaching modules properly according to the goals, needs and characteristics of the school independently.
