1.5. Can you solve this?

1.5.1. channel: Veritasium - channel of science and engineering videos featuring experiments, expert interviews, cool demos, and discussions with the public about everything science (with a sort of editor in chief)

1.5.2. interesting features engagement of other people that show up in the video (e.g. ordinary people) and of video watchers, that are stimulated by the question asked spectacular effects various types of equipment (e.g. gopro, gingle/tripod for smartphone), multi-operator framing, stop motion solutions explained through many examples to support learning

1.5.3. videos are recorded in a captivating context /scenario

1.5.4. substantial directing and video editing expertise

1.5.5. captivating (smiling & self-confident) presenter

1.6. Bowling in Slow Motion with Blue Man Group

1.8.5. the issue: compromise between autoritative content and compelling style

1.8.6. video on the channel are developed for various funder /customers; that has an impact on the content narrative / style (e.g. more in-depth content at The Immune System Explained I – Bacteria Infection the immune system explained). Caveat: wich autoritativeness / sources for the content?

1.8.7. video "challenger": Gravitationswellen - Wellen in der Raumzeit plain, and clearly explained content,, focus on content rather than on graphics, autoritative source (Max Plank Gesellschaft)

2. Group activity: METID people are divided into groups of 3-4 people each. Each group has to explore a specific YouTube channel (45 mins) and to choose the best video along with another video "challenger"

3. food for thought

3.1. it is important to consider both the aim of the video and the aim of the video context

3.2. purposes of explored videos (beyond providing analytical explanations)

3.2.1. providing analytical explanations

3.2.2. supporting memorization of concepts e.g. The NEW Periodic Table Song (Updated)

3.2.3. stimulating direct experience e.g. How to See Without Glasses

3.2.4. sparking reflection / curiosity e.g. Why Age? Should We End Aging Forever?

3.3. anatomy of videos

3.3.1. a "hook" is often used to catch people's attention e.g. starting with a question, starting with an unusual or interesting object or fact; leveraging aesthetic / artistic appeal

3.3.2. mix of content formats e.g. outdoor video footage, lab footage, footage of text content real-life objects combined with graphics, 3D, photographs, video footage of software, storytelling sometimes the mix is overdone (reduced learning effectiveness), e.g. Fried Chicken’s Deliciousness, Explained

3.4. technical aspects: steadycam and drones for outdoor footage, slow motion

3.5. accessibility - design for all: e.g. video transcripts, text readability (font size and contrast), content accassibility on mobile devices (e.g. smartphone, tablet)

3.5.1. relevant to delivered quality of video

3.5.2. caveat: unreadable material from content experts can not be accepted for video production and has to be redone (negotiating who is in charge of it)

3.5.3. caveat: sometimes (rarely) the message can be conveyed by the general pattern instead than by reading the details

3.6. any content that can not be effectively conveyed in video format has to be delivered in other formats
