Adding brush effect in GIF image

well this tutorial helps u make GIFs like this

u need well photoshop nothing more but for different new fonts like the ones used in these two u need to download more fonts 

u can google them or simply download it from here

http://www.dafont.com/

so first open PS and then open your GIF in which you want effects like this or simply make one (will give a tutorial on this later ;) 

so the one i have used a GIF image that has 63 layers = 63 frames

using the play button u can see how ur GIF plays and then cut extra frames if any that u don't want

and then crop the extra space of your GIF that u don't want

^^ this is the image i got after i used crop (using crop option isn't necessary)

 now u go to layer > New Layer > OK

the new layer will be shown in layer's window

Note : it should be shown on the top of all other layers if not and is above layer 1 then select New layer and drag it up till it reaches the top of all layers

 << drag this layer

 and it should reach here if it already was not

 now select the brush tool

 then go to window > brushes 

 here u select what type of brush u want to use and its properties 

 change the size of brush from here or the option in the top left :)

 i have used this brush size which is large enough but not too large

 so on the new layer start applying brush the way u want it to be shown on your GIF

at the end of using white brush your GIF will look like this ^^

and your frame timeline like this - 

^this shows brush has been applied to all frames

and ur layer window will be like this

now again add a new layer above this layer

use a different type of brush or the same one

 layer a is the new layer now

 here change the size and color of brush again

apply the same way

now selecting layer a go to layer > merge down

 so it will be like this now in layer window

now again go to layer > new layer

 

selecting the text tool and the font type and size type the text on this new layer

the Layer's window will be like this

now selecting text layer go to layer > merge down

play your GIF and look at the final result if it is alright go to file > save for web > following the procedure save your GIF image :)

for the second one where u can't use brush on the image becoz it may hide the image or the GIF size is small after cropping and all go to canvas size > increase the width or height or both and then following the same procedure add brush but use brush mostly on the increased canvas space
