Hello Seul,
I think your post is very clear and organized. It is easy for me to read and follow. I really enjoy watching the video you shared and I think the use of animated characters can attract audience’s attention and make them feel more interested in the content as well. I agree that this video can be seen as interaction with learning materials. For me, I can directly learn the knowledge in relation to your topic on this video without the direct intervention from my peers. Moreover, I think this video is available for learners who have English as a second language (ESL). I agree that the use of subtitles in the video is quite helpful as well.
