It all depends on what you want, do you want an animated outro or a still outro? Animated outros are a bit harder to make and most people get a template. However, still outros are easy to make since you only need to get a picture you like and turn it into a video by putting it through an editor. Personally I think still outros would be best. I have one and its perfectly fine. Just grab a picture you like, put it into your editor, make it about 20 seconds (for end cards) and add some music and your done! If you wanted an animated outro I reccomend searching around YouTube. There are tons of videos with templates you could use.
Hope this helped!
