Video overlay - how is this effect created?
I was able to produce it by doing the following:


Convert the video to monochrome by turning the saturation down
Apply Levels and bring the output black point up to around 30%
Put an orange color solid over it and set the opacity to 50%
Set the blend mode to "Normal," "Overlay," or "Hard Light"


You can experiment with the black point and blend modes to get the look just right for your footage.
