this is a short footage where you will see the effect i want to recreate in After Effects. This one was made with a video camera (don't know exactly how)
I already know how to separate RGB channels... but how to precisly recreate this (i mean the way the two images are blending,the special way RGB are separated etc...)

Thnak you in advance !

Duplicate the footage twice, use the Set Channels effect to turn them red, green and blue, and set the top two layers to the Add transfer (or blending) mode. Fart around with the top two layers' position, and add blur to taste.

Nest it in another comp, and play with opacity and more footage. Done.

thank you dave
i was ok with the RGB separation.
but i don't think it is only a question of opacity.
there is something like a wiper with a very high feather.but i am not sure

i haven't AE now so i can't test
but it is something like that, maybe
