You can use the Kaltura plugin in the text editor (Atto) to embed video content.
The text editor is used to create the following content types in Moodle:
The text editor is also available from the Description field of activities or resources and within Quiz questions.
Embedding videos within a resource ensures that students can access the relevant video content as they need it. It also provides a more integrated navigation experience as students can review text and video content within the same resource without having to navigate back to the module homepage.
Performance & access
Do not embed more than three video files using Label on your module page. Videos embedded via a Label load as the student accesses the module and impact on module load times and performance.
Labels cannot be accessed by students from the Module index. Do not put any learning content into Labels as it might be missed by students navigating using the Module index.
