To change the privacy settings for individual videos you've posted on Facebook, follow these steps:

1. Sign in to your Facebook account using your login information. Once logged in, navigate to your profile page or the page where you have uploaded the videos.

2. Locate the video you want to modify the privacy settings for. You can find your videos by scrolling through your timeline, visiting the "Videos" tab on your profile, or accessing the "Videos" section on a specific Facebook page you manage.

3. Once you've found the video, click on it to open it in a larger view or enter the video's dedicated page.

4. On the video page, you'll notice various options and buttons. Look for the three-dot menu button, which is usually located in the top-right corner of the video player. Clicking on it will unveil a dropdown menu containing various options.

5. Within the dropdown menu, find and choose the option labeled "Edit Privacy" or "Privacy Settings". This will open the privacy settings for the selected video.

6. A pop-up window or a new page will appear, presenting you with different privacy options for the video. Facebook offers several privacy settings:

• Public: Selecting this option will make your video visible to anyone on Facebook, including people who are not connected to you. It may also be searchable on Facebook and other search engines.
• Friends: This option restricts the video's visibility to your Facebook friends only. It will not be accessible to people who are not on your friends list.
• Friends Except: This option allows you to choose specific friends or groups of friends who will not be able to see the video. You can manually exclude individuals or predefined friend lists from accessing the video.
• Specific Friends: This option allows you to select specific friends or friend lists who will have access to the video. You can customize the visibility based on your preferences.
• Only Me: Selecting this option makes the video visible to you alone. It will not be viewable by anyone else on Facebook.

7. Choose the desired privacy setting by clicking on the appropriate option. As you make changes, Facebook may display a brief description of what the chosen setting entails.

8. After selecting the privacy setting, click the "Save" or "Apply" button to save the changes. The button's label may vary, but it should be prominently displayed on the page or within the pop-up window.

9. Once saved, the privacy settings for the video will be updated according to your selection. You can confirm the changes by checking the video's privacy status or viewing the video as a different user to ensure it's now accessible or hidden as intended.

Facebook provides users with flexibility and control over their privacy settings, allowing you to manage who can see your videos. If you encounter any issues or have further questions, refer to Facebook's Help Center or support resources for more detailed instructions and assistance.
