Hello Brian
The link Bill posted are prebuild presets that makes life so much easier (thank God for those), but the effect is not that hard to do in After Effects. First create a new Red Solid and add the following effects: Hue/Saturation and CC Light Rays
After this you will need to animate the CC Light Rays using a couple of keyframes. I animated the “Intensity” and the “Color”. I also animated the “Opacity” of the Red Solid. With the layer opacity you will be able to control the amount of color intensity of the transition (also the start and ending point). Here are the values I use: (Note: I use a 1920×1080 Square Pixels composition)
Hue/Saturation
Check Mark “Colorize”
Colorize Hue: 0x +8.0
Colorize Saturation: 45
CC Light Rays
Intensity: This one have two keyframes. The first keyframe value is 0, the second keyframe (which is 10 frames from the first) has a value of 1300.
Center: 1888.0 38.0
Radius: 104.0
Warp Softness: 205.0
Shape: Round
Uncheck “Color from Source” and select a your desirable color. You will need to keyframe the color to make the color change from soft red to the yellowish color. This color keyframes must be the exact same distance as the “Intensity” keyframes (in my case is 10 frames). I use the following colors; first keyframe F8814D, second keyframe E7C731.
To increase the transition intensity, increase the opacity from the whole layer. The opacity keyframes needs to be animated at the exact same distance as the “Intensity” and “Color” keyframes (in my case 10 frames). Of course, the opacity starts at 0%, but when you want the transition to start, you make the first keyframe with a value of around 50% and the second keyframe with a value of 100% (so you will end with three keyframes in Opacity)
That how you do the transition from the video. Of course, why bother doing all this work when you can buy a pre made preset 🙂
The meaning of a movie is in its characters, the life of the movie is in the music, but the magic is in the editing.
