How to I make the fade in fade out text because there isn’t any filter for it.
Use the forum Search, this has been asked so many times. There are numerous threads some of which include video tutorials.
You can try duplicating the video that is supposed to have text and put it on a layer above and add fade in/out or you can use a transparent layer as used in the following video. Check if the first five seconds of this video are what you want. If not, better skip it.
You could also do this using the Overlay HTML filter.
