Make your description clear and specific.
Your video should stand out from the crowd. Try to determine what content it contains that will help users find it and distinguish it from other videos. Using descriptive language in complete sentences is a good idea.

Give credit when appropriate.
If people don't know the exact title or other keywords associated with your video, they might search the name of a participant or another website where it's featured. Be sure to include as much information as you feel comfortable, but be careful not to include anything that shouldn't be publicly displayed.

Categorize correctly.
The category into which you place your video is part of its description as well. People are more likely to rate your video highly and watch it more frequently if it's placed in a relevant category.

If you're logged in and aren't able to rate, your email address may not be confirmed. To request a confirmation email, log in and click the "Upload" button in the upper right corner of any YouTube page. Enter your email and click the "Send Confirmation" button. If you still don't see it in your Inbox, try looking in your spam folder.

If you've clicked the link in the confirmation email and are still having trouble, try deleting your browser's cache and cookies, relaunching your browser, and logging back in to YouTube.

Record a Video
YouTube will automatically attempt to detect your computer's settings if you choose to respond via QuickCapture. Click the "Allow" button in the window that pops up so that YouTube can access your camera and microphone. Before you can begin recording your webcam response, be sure to enter information into all the fields on the left hand side of the screen.

Choose a Video
The dropdown here allows you to respond with any video you’ve already posted. One thing to keep in mind—your video can only be used as a response once. If you've used a video as a response in the past and want to use it for a new response, it will no longer be listed as the earlier response.

Upload a Video
This works pretty similarly to the normal upload process. Click the "Upload a Video" link. Enter all of your video's information, then click either "Go upload a file" to upload a file, or "Use QuickCapture" if you decide to use your webcam after all.

Videos
Along the top of the stream, you’ll see thumbnails and partial titles for all of the videos currently in the room; clicking one will move it to the player for you to watch.

Chatting
On the right side of the screen, you’ll see a list of all the YouTube users in the room, the ongoing chat, and an open text box where you can type your comments. Just type in the box and click "Enter" to see your comment appear. It will appear in the conversation with your currently watched video as the icon (unless you uncheck the "Include current video" checkbox).

After you pick the stream you want to join, you'll see a welcome message from the Stream owner, and you will appear in the chat as a new member of the room. You can only be in one Stream at a time.

• Go to your Profile page.
• In the Videos section, click the "Playlists" link.
• Click the "Create New Playlist" button. Clicking that button will take you to a page where you can first add some personality to your Playlist, with a title, description, and tags.
• Click the box next to "Use this playlist as my Video Log in my Channel" and the videos from this list will automatically appear on your profile page.
• You can add videos to your Vlog by saving to that playlist or transferring videos from other playlists or your Favorites.

There's another way to create your Vlog! Just open any of the Playlists you've already created and click "Set as Vlog."

To close your account:

1. Log in with your user name and password.

3. In the "Account Settings" section, click the "Close Account" button.

6. Click the "Send Email" button.
7. Check to see if you've received an email from YouTube in the account you entered. (If you don't see it after several minutes, check your Spam folder to see if it was filtered out of your main Inbox.)
8. Once you've opened the email, click the included link. You will be brought to a page that says, "Your email has been confirmed."

If you think you signed up with an alternate email address, then you may want to enter that email address into our "Forgot Username" form (http://www.youtube.com/forgot_username). If that doesn't help, try signing up again (http://www.youtube.com/signup).

Copyright Infringement Notification

To file a copyright infringement notification with us, you will need to send a written communication that includes substantially the following (please consult your legal counsel or see Section 512(c)(3) of the Copyright Act to confirm these requirements):

2. Identification of the copyrighted work claimed to have been infringed, or, if multiple copyrighted works at a single online site are covered by a single notification, a representative list of such works at that site.
3. Identification of the material that is claimed to be infringing or to be the subject of infringing activity and that is to be removed or access to which is to be disabled, and information reasonably sufficient to permit the service provider to locate the material. Providing URLs in the body of an email is the best way to help us locate content quickly.
4. Information reasonably sufficient to permit the service provider to contact the complaining party, such as an address, telephone number, and, if available, an electronic mail address at which the complaining party may be contacted.
5. A statement that the complaining party has a good faith belief that use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law.

Please also note that under Section 512(f) any person who knowingly materially misrepresents that material or activity is infringing may be subject to liability.

If there are many videos to be removed, or you expect to have an ongoing need to remove potentially infringing content from YouTube, we suggest that you sign up for our Content Verification Program which electronically notifies us, removing any room for error, and significantly increases the speed at which we are able to remove any infringing content.

Counter-Notification

If you elect to send us a counter notice, to be effective it must be a written communication provided to our designated agent that includes substantially the following (please consult your legal counsel or see 17 U.S.C. Section 512(g)(3) to confirm these requirements):

1. A physical or electronic signature of the subscriber.
2. Identification of the material that has been removed or to which access has been disabled and the location at which the material appeared before it was removed or access to it was disabled.
3. A statement under penalty of perjury that the subscriber has a good faith belief that the material was removed or disabled as a result of mistake or misidentification of the material to be removed or disabled.
4. The subscriber's name, address, and telephone number, and a statement that the subscriber consents to the jurisdiction of Federal District Court for the judicial district in which the address is located, or if the subscriber's address is outside of the United States, for any judicial district in which the service provider may be found, and that the subscriber will accept service of process from the person who provided notification under subsection (c)(1)(C) or an agent of such person.

Such written notice should be sent to our designated agent as follows:

Please note that under Section 512(f) of the Copyright Act, any person who knowingly materially misrepresents that material or activity was removed or disabled by mistake or misidentification may be subject to liability. Please also be advised that we enforce a policy that provides for the termination in appropriate circumstances of subscribers who are repeat infringers.

• I recorded my video at a sporting event, concert or from television or a DVD.
   
• Why was my video removed for copyright while similar videos were not?

To file a counter notification with us, you must provide a written communication that sets forth the items specified below. Please note that you will be liable for damages (including costs and attorneys' fees) if you materially misrepresent that a product or activity is not infringing the copyrights of others. Accordingly, if you are not sure whether certain material infringes the copyrights of others, we suggest that you first contact an attorney.

Please understand that filing a counter notice may lead to legal proceedings between you and the complaining party to determine ownership, and if your claim is rejected, you may face severe legal and financial penalties.

A sample counter notification may be found at: www.chillingeffects.org/dmca/counter512.pdf.

To expedite our ability to process your counter notification, please use the following format (including section numbers):

2. Provide your name, address, telephone number, email address, and a statement that you consent to the jurisdiction of Federal District Court for the judicial district in which your address is located (or San Francisco County, California if your address is outside of the United States), and that you will accept service of process from the person who provided notification under subsection (c)(1)(C) or an agent of such person.

3. Include the following statement: "I swear, under penalty of perjury, that I have a good faith belief that each search result or message identified above was removed or disabled as a result of a mistake or misidentification of the material to be removed or disabled."

4. Sign the paper.

For example, you can use one of the methods in our API to search for all videos tagged "sugar glider." The call would return all the relevant video information in raw XML (Extensible Markup Language). You could then take this information and display pages of only sugar glider videos on your site.

How is this different than searching for the videos yourself on YouTube.com and pasting in embed code? Well, the pages on your site would be dynamic, meaning that they would update on their own when more sugar glider videos were added to YouTube.

We offer two styles of API calls that you can use, REST and XML-RPC.

For more detailed information regarding developer APIs, including what methods we offer, and how to start using them, check out the Developer Homepage (http://www.youtube.com/dev). You might also want to check out our Developer Forum (http://groups.google.com/group/youtube-api) to talk to other people who are using the API.

If you don't receive either the welcome or confirmation email when you expect to, check in your email client's spam folder—some are more aggressive than others about identifying spam. If you still haven't received it after several hours, you can try confirming your email again with a different email address by returning to the "Upload" page (http://www.youtube.com/my_videos_upload).
