Create custom lens flare in after effect

-First open your after effect and create new composition or ctrl + N in keyboard set 1920 * 1080 -create layer new adjusment layer , and add lens flare in the effect -->generate ---> lens flare
second make a shape layer with with make like this ,

and add glow also box blur, you can find glow in effect-->stylize --> glow , effect -->blur and sharpen --> box blur and set like this

open the shape layer , press "P" on keyboard to set the position, alt klik on the stopwatch of position , and add like this replace transform.position to  thisComp.layer("Adjustment Layer 9").effect("Lens Flare")("Flare Center")

and now u can move the lens flare in the adjusment layer ... and the shape layer will follow so u can make a custom lens flare, 

Introduction to pixel bender

Pixel bender is programming language created by Adobe Systems for the description of image processing algorithms. The syntax is based on GLSL, and a Pixel Bender program is analogous to an OpenGL fragment shader, and is intended to be a loosely typed version of C++.
with pixel bender we can make a our own plug in to after effect

in this tutorial above we can make cropping plug in .. so try this to make your own plug in

Make a reflection text in after effect (beginner)

-First open your after effect and create new composition or ctrl + N in keyboard set 1920 * 1080
-second make a new layer solid make it white to make a background and rename that to "BAckGround"
-third make a new solid again , and make it black to the color and rename it spotlight
-fourth make circle and double klik in the spotlight . so u will make a mask ... and in the mask layer klik add change to subtract , and change mask feather 300 pixel and reduce the opacity of mask to 25%
-fifth make a text, and rename it to CUman GItu, with verdana text type and make that double ctrl+D on the keyboard
another text rename that to reflection
scale that reflection layer and scale unlink that 2 type text .. and change 100% 100% become 100% -100%
and add linear wipe ... in that reflection layer, make wipe angle to 0 and transition complete to 45% change the opacity of reflection to 35%
sixth in the text cuman gitu ... add ramp ,, from effect--> generate ramp to make that like a gradient text , more like glossy.

Make animated background in after effect

In this tutorial we will make use effect from after effect
1. Advanced Lightning
2. CC star burst
3. solid composite
4. Curves
5.Transform
6.mosaic
7. Find edges
8. Glow curves

-First open your after effect and create new composition or ctrl + N in keyboard set 1920 * 1080
-create solid with whatever color and add effect advanced lightning . effect --> generate --> advanced lightning set like this

set decay in first time indicator to = 0.82 second time indicator set decay to = 0
and add effect CC star burst, solid composite  Curves

and add effect.Transform mosaic Find edges

and add effect Glow and curves

tadaaa u can see u have digital animated background

Make a text explosion in after effect

First time . make a new compositon or ctrl + N in keyboard and make a text .  and pre compose it

after that add a new effect  cc force motion blur 

 and it will take a long time to render.. but .. it's nice explosion in after effect only use 2 effect pixel polly and cc force motion blur ...... 

Make an abstract background in after effect

In after effect we can make an abstract background with fractal noise

fractal noise is very usefull effect to make background in this case we make background .. and the setting is like this ... go check it out

and we add bezier warp effect to smooth the line...
