This is an ongoing discussion by both professional and hobbyist Angel breeder and just about everything you need to know on the subject has been discussed in it already.
As for your fish in the pic, the first question needs to be "Are there more Angels in tank besides just these 2 Angelfish?" If there are, this could very well be 2 males fighting for breeding rights to a female in the tank. This can be a brutal fighting leaving one or both males with dents and dings. You will notice the fish not only lip locking but also going after other parts of the body. That's usually a clue as to their intentions. If there aren't others, the fighting should be short lived as usually there is submission rather quickly by the weaker fish if it's 2 males PLUS, since there is no female there to fight over, there is no "kingdom" for them to fight about.
If this is a male and female,( I'm not sure based on this pic alone) Lip locking will last a bit longer as the male is looking for the female to submit. There may be some tail nipping but body blows do not regularly happen as when they are fighting. There is a test I find very useful in sexing larger Angels. Before you feed the fish their first meal of the day, look down at them from above the tank so that you are looking straight down the fish. A male will look like a straight line from top to bottom. A female, gravid with eggs, will have a slight bulge in her abdomen and will clearly look different than the male. Again, this must be done before the fish eat because a belly full of food looks the same on a male and a female.
As for loading videos, use the "go advanced" tab to make a post and below the posting area, there will be a section titled" Additional options". In the "attach files" section, there will be a button "manage attachments" that you click on. This will bring up a separate window where you will have the option to load your videos. This is how I do mine. It goes directly from my computer to this site. No Utube or any other sites necessary
Hope this helps
