How to create a flash whiteout transitional effect?
So im working on a project in which there is a flashback sequence, and I want to know how in the simplest way possible to add a transitional effect so that at the point the character flashes back, the screen whites out in a flash (bulb like effect). I am relatively inexperienced with After Effects so the simplest the better, Im much more knowledgable with Final Cut, and the flash effect i want really isn’t possible there, all you can really do is Fade to white, which isn’t going to suffice.
If we all went and edited our pasts, we would all be living in very boring films.

check out the Ae podcast that Aharon does, there is a tutorial on this effect in there.

I’ve used this a lot. Create a new white solid about 2 secs long. keyframe the opacity 0% at begining of layer 90% at 1 sec and 0% at 2 secs.). Set the transfer mode to classic color dodge. Now create an adjustment layer the same length as the white layer. Add a gaussian blur effect to it. Keyframe the blur 0 pixels at beginning, 30 pixels at 1 sec and 0 pixels at 2 secs. now line the 2 layers up above your footage so that the middle keyframe of each layer is right at the cut of your 2 footage clips. Experiment with the amount of blur and opacity on the white layer. Usually i put the blur layer on top of the white layer. It’s also nice if you dissolve between the footage layers under the effect.

I would recommend using the Levels effect on an adjustment layer and animating the white input down (this make the light parts of your image become even lighter), you can also animate the black output up (making the dark parts of the image lighter).
A Blur is a good effect to add, but I wouldn’t use a Gaussian Blur, go ahead and use a Fast Blur or a Box Blur (set iterations to 2 or 3 and play with the radius) as these render much much faster and give you good results. Box Blur is almost identical to Fast Blur at 3 iterations, and you can fine tune the iterations for more a boxy (lower number) or a more smooth (higher number) blur. Keeping in mind that more iterations = more render time you should never really have to go above 5.

The Effect Essentials plug-in “Camera Flash” obviously does a fine job of this. Of course, you gotta buy it….
