Creating the look of heat rising off pavement?
I was recently asked to create the look of heat rising off pavement causing the air above it to warp and was totally stumped as to how to make this happen.
Anyone ever try to create this?
Thanks

If you don’t have Shake, you could use a displacement map in AE, using the fractal noise to generate the map. In Motion, you might be able to do the same thing using a displacement filter & a particle generator (one of the smoke or fog presets) to create the map.

If you’re searching for tutorials on the subject, the term you’ll want to use is “Heat Distortion.” I created this once (many years ago and I think I did so in AE) to simulate the heat distortion caused by a jet engine.
You can create a similar effect in FCP, but if you have a very specific area you are trying to distort, then I suggest going with AE because of the ability to create more unique mask shapes.
This is my best method to create it quick/cheap in FCP: Duplicate the layer and place it on top of the original footage. You will only add effects to the top layer from here. Crop the top layer so that it only covers the area where you would like the heat distortion to occur. Feather the clip between 50-70. Drop the opacity to 60 or so.
Add a blur (I prefer Gaussian with a radius of at least 10).
Then add the “Wave” distortion effect. Set Amplitude to .2, Wave Length to 6, Speed to 40, check both “Vertical” and “Repeat Edges.” This should get you on the right path…
Season to taste using a bit of glow, possibly an echo effect, and desaturate the clip.
