# YouTube

YouTube is a popular free video sharing website which lets users upload, view, and share video clips. Videos can be rated, and the average rating and the number of times a video has been watched are both published. The main purpose of this project is to find and promote educational videos, though it isn't necessary for this learning resource to be only about that. Focusing on the interface user experience (Q1047808) and exploring alternative interfaces might be topics to explore, among other things. Another topic that can be explored is the mechanics of the site, interacting with the site with various software. Comparing functionality between users that have logged in and visitors to the site. Exploring the legal terms to which one is bound to when registering or otherwise using the site. For further discussion and suggestions of similar sites please see the talk page.
YouTube also is one of the most popular sites on the internet to watch a different videos uploading of many citizens. It is a site that you can easily view and watch many videos. You can react to all videos as long as you have an account for this site it can allow you to comment, like, or dislike the video. Million of citizens use this site because it's a lot of purposes for us. You can upload a video for advertising, for entertaining, for expressing, for researching, for educating, and many more. So it can be the one of the best site in the internet.

## Channel page

Channel pages are divided into multiple sub pages including "Home" (front page), "Videos", "Playlists", "Channels" with other channels featured by the user, "Discussion" or "Community" depending on subscriber count, and "About" for channel description and information.
Videos can be sorted by most recent (default), oldest, and popularity (view count). This can be done through the drop-down menu or the URL parameters sort=dd, sort=da, and sort=p respectively.
On the desktop site, flow=grid and flow=list formerly changed the appearance of the video list, of which grid view shows a more compact layout with multiple videos per row, whereas list view shows a short snippet of each video's description text. User reports suggest that this feature has been removed in June 2020, and only grid view remained.

## Studio

YouTube is equipped with a digital Studio, with a wide range of tools to manage videos.

### Subtitles

YouTube allows automatically generating and/or transcribing subtitles. These features are accessible from the video options inside the channel management (Creator Studio).

### Analytics

YouTube Analytics is a toolbox which allows video creators to analyze their audience, in order to optimize their content. For example, users can view which parts of the video were played most, how long the audience watches a video on average, geographical data (a list and a map with views by country), and views by device type (desktop, Android, iOS, game consoles, Smart TV, etc.).

### Cards

Users can add Info cards and end cards to videos, which can contain suggestions for other videos to watch or channels to open. The video can be a random or the most recent upload from one's own channel, as well as any specifically selected video. Polls with up to five were supported until 2020.
This feature is a partial successor of the discontinued annotations, which YouTube did not bother to adapt to their mobile application and web site front ends.

## Tips

* It is recommended to keep offline backups of videos, as YouTube effectively acts like cloud storage when used for video, over which the uploader lacks technical control. Depending on an online service to retain data without having a local copy is a frequent cause of data loss.
* When reviewing cameras, make sure to show crops of pictures and footage zoomed well beyond 100%, as not all viewers watch at the highest resolution to be able to view the full detail.
* Screen recordings can be made more convenient to watch on mobile devices by setting a lower resolution to make interface elements appear larger.

## Learning Project

This unit is associated with Topic:Internet Audio and Video.

## How to hunt

First add major scientific field (or other) names to the built in search engine, like biology, chemistry, language learning, tutorial, etc. Not all videos displayed are suitable to link into this page however, so it is up to you to select the appropriate ones (should be educational related). Browse also the Related videos and More videos from the same user to find more material. Happy hunting!

### Physics and Astronomy

* Gravity visualized 2 meter diameter stretched membrane depicts gravity, orbits, dark matter, and the formation of the solar system.
* Make an amazing magic ball Demonstrates the concept of torque, center of mass, and potential energy: A weighted ball on a ramp will not roll because although a torque is developed, the center of mass is displaced from the center of the ball. This would cause the ball's center of mass to rise if it rolled. But this ball has an extra property that makes it seem alive. Easily explained and understood.
* Make a cloud dissappear (Physical science) When water vapor is supersaturated it means that the pressure and temperature are such that droplets should form. But the molecules have trouble "finding each other" unless a small particles (called aerosols) are in the air. The sudden decompression somehow plays a role...but how?
* Hammer torque demo. The center of mass (gravity) is directly below the balance point.
* Chaos
