Next I made a very dark radial gradient then set it to 75% multiply.
Now go layer>video layer>new video layer from file and choose one of the videos you downloaded. Now go window>animation to bring up the animation panel. You will now have what looks like a histogram of the time, all except one of the layers should have an infinite time, the one that doesn’t is your video layer and should be at the top. Move the time slider to the end of this layer, see the image below for reference. You will see that the animation will move, the reason we moved the slider to the end was because if you watch it you will see that the last 10 seconds include every part of the animation.
Now hit Ctrl+T to enter free transform mode, a warning should pop up just press convert and it should change to a smart object. Next move, rotate and scle it then put it above part of your text, here I put it above the first R.
Now we are going to mask it, I used similar techniques to what we used when masking the letters. Note that when you mask a video layer it does this in every frame. Ctrl+click on the text layer to make a selection then get the polygonal lasso tool out, hold Alt+Shift to go to intersect mode then draw roughly round the part you want to hide behind the letters like shown below; the purple line being the selection I made.
Now mask the video layer in exactly the same way as in step 14 and 15. Do this for some other parts of the animation.
Right click on the video layer then go blending options, that’s right you can add layer styles to a video. Use the settings shown below. Make sure that ‘Layer Mask Hides Effects’ is checked as this will make the shadow more accurate because the shadow won’t follow the layer mask at all. For the color overlay, just select the color that the animation merges into with the eyedropper, so here mine merged into the green line.
