To delete a video from Facebook on your iPhone, you can follow these steps:
1. Open the Facebook app on your iPhone and go to your profile by tapping on your profile picture at the bottom right.
2. Scroll down on your profile until you see the “Photos” tab and tap on it.
3. Once you’re on the Photos page, tap on the “Albums” tab at the top.
4. Among the list of albums, look for the “Videos” album and tap on it.
5. You will now see all the videos you have uploaded on Facebook. Scroll through the list and find the video you want to delete.
6. Tap on the video to open it and start playing.
7. On the bottom right corner of the video, you will find a set of three dots arranged vertically. Tap on these dots.
8. A menu will appear with several options. Tap on “Delete” from the menu.
9. Facebook will then ask you to confirm the deletion. Tap on “Delete” again to confirm and remove the video from your Facebook account.
Please note that deleting a video from Facebook will permanently remove it from your profile and it cannot be recovered. Make sure you are certain about deleting the video before proceeding.
Also, keep in mind that these steps are specifically for the Facebook app on an iPhone. The process may slightly differ if you are using a different device or the Facebook website on a browser.
