FX Filters that change with the sound of the clip
So let's say I have a clip with a filter on it (contrast, threshold, whatever) I want an attribute of the filter to change according to the trend of the sound that accompanies the clip.
So if I have a clip of a man talking, If he isn't speaking, there is no effect, if he is whispering, there is a little effect, if he's yelling, the effect is very pronounced. How can I make this happen? What software do I need? I have FCP and Motion. But I can get access to other things through my school if need be. |
You may want to check out After Effects.
With the 'Turn Amplitude Into Keyframes' (I think it's called) setting, you get a number, I believe 0-1 or 0-100, of percentage of max volume. You can then tell any setting on any effect to use this value. For example, the sound clip of a flickering light (zzzt-zzzzt) could change the opacity of the video layer, giving the appearance of the light flickering, set by the noise. C |
Good advice, or, really, you could just look at the waveform and do the same thing by hand in any application. Might be a bit slow, but shouldn't be too hard.

Another good resource for AE.
