Achieving Certain Effects

I've been looking around for vids that would inspire me to make my FF7 vid, and I saw this video with really cool white flashes with it. How do you achieve that sort of effect?

Depends on your editing software.

I'm not sure how it's done in Windows Movie Maker but it IS done in it a lot, so there must be a way. Some sort of fade-to-white effect in there?

In Premiere, the standard method is to place a totally white Color Matte on the track above your video track and use the opacity settings to make it completely transparent for most of the video, and opaque for the brief 'flashes'. Please please please fade the transition from totally visible to totally transparent a little bit though, as 'seizure flashes' are just highly annoying.

If there isn't, you could always make a white matte, import it, and fade in and out of it really fast like with any other clip.

I would prefer to use a brightness filter and keyframe it.

I would prefer not to see yet another cheesy, half-assed FF7 video filled with generic white flashes in lieu of any other sort of synchronization.

You don't have to

Also, two words:

Convolution kernel.

Learn how to use that if you really want flashes. Everything else is boring and unnatural-looking.

That Looks a bit on the confusing side. After hiting the readme file however, I made a bit more sence of it. Playing around with the presets should also help.

(re: convolution kernel)

Playing around with this...I don't see any reason to add adjacent pixels if all you want is a brightness effect. I think I'd leave the matrix alone, un-check Auto normalize, and then adjust the Scale.

It looks like the Sony Vegas Glow effect does the same thing as long as you leave Glow percent at 0.0 and only use the intensity slider. But it also appears that Glow will wash the color out of the scene.

you can also use the bump map filter. While it cant make the image 100% bright, it can go a fair distance, and the colour doesnt seem to wash out. Their also other filters which can be used to achive the effect in thier own way. But I'l just stikc th the brightness and contrast filter
