Film Burn Effect

This is the video tutorial I watched for the effect on Adobe After Effects called Film Burn.
I created this Film Burn Effect at the beginning and end of the clip. I felt this gave the clip and interesting effect. First I downloaded the Film Burn Clip from the download link on the youtube video in the video's description. I then added the Film Burn Clip to the Adobe After Effects Timeline. I then also added my Rizzle Kicks Intro to the timeline. I copied and pasted the clip so that it was at the beginning and end of the clip. I then set a keyframe on the first Film Burn Clip when the Rizzle Kicks Intro begins. I set this keyframe to be at 100% opacity. I then whent a second into the Rizzle Kicks Intro and set another keyframe on the Film Burn Clip to have 0% opacity. This made the Film Burn slowly fade into the Rizzle Kicks Intro giving it an interesting effect.
I then went to the last Film Burn Clip and whent to when the Rizzle Kicks Intro has a second left and set a keyframe on the Film Burn Clip to have 0% opacity. I then whent to the end of the Rizzle Kicks Intro and set another keyframe to have 100% opacity. This created the same effect as the first except reversed with the Rizzle Kicks Intro slowly fading into the Film Burn Clip.
