If you want to save a Youtube video to your iPhone’s camera roll, you first need to open the Youtube app and find the video you want to save. Once you’ve found the video, tap on it and then select “Save Video.” Next, choose where you want to save the video. You can either choose “Camera Roll” or “My Videos.” If you choose Camera Roll, the video will be saved in a new folder called “Camera Roll.” If you choose My Videos, the video will be saved in the same folder as the YouTube app itself. Once you’ve chosen where to save the video, tap on “Save” and then wait for the video to be saved. ..
