So that was my second time using after effects but I don't know how I could improve it! How do I make the muzzle flare have the same quality as the original video because the muzzle flare quality is in 720p and it just makes it look unrealistic. I have a really bad camera so I can't do much with the quality. It would be awesome if you could show me the errors I made and tell me a step by step instruction on how I could fix this as I don't know where everything else is located in After Effects.
One suggestion is to use a gaussian blur on the muzzle flare layer. What this will do is soften the appearrance of the flare so that the edges are more realistic.
I also found a quick tutorial on youtube at http://www.youtube.com/watch?v=SsViAvVYoMQ&feature=related. Hopefully this helps.
