Video conferencing systems save time and resources. This can be said as these systems prevent travel and travel expenses. Making the recording of these meetings available allows asynchronous access to those who cannot attend or want to review the video. The purpose of this work was to analyze the operation of video recording in videoconferencing systems and, in addition, the implementation of a recording system was implemented. And to better evaluate this implementation its performance was analyzed on different hardware. The scope of this study can be divided into three parts: subject contextualization, tool development and evaluation through comparative tests. In the first part are presented concepts that bring the reader closer to the subject and also a brief notion of the market on the subject. In development is shown all the construction of the tool from the architecture designed to the use cases worked. In the final part, all the tests proposed in the validation are worked and then the obtained results are presented through tables. Regarding the results, it will be observed that, regardless of the hardware or tools used, the presence of video transcoding is a determining factor in the negative performance since it generates high CPU consumption. On the other hand, its presence brings a result that can be considered positive in the size of the generated files. Thus, it is up to the system user to decide to measure the most cost-effective for their application.
