For a few dollars you can buy replacement lenses without IR cut filter for popular FPV cameras and also IR passthrough filters from eBay. Additionally, many digital cameras can be modified for IR recording by simply removing the IR cut filter from the sensor. As a result you get very pinkish footage.

I have written about the postprocessing of IR photos already earlier (s. here). This video just quickly shows a few possibilities to edit the footage to make it more useful for analysis.

The postprocessing is done with KDEnlive for Linux.

Thanks for the share. Can this software easily do a N-IR NDVI image?

I think it still lacks some functions but the underlying MLT framework should be able to do that. Learning the MLT scripting language is on my list - as is making yet another lens for my Boscam with a Rosco 2007 filter :).
