Destin from SmarterEveryDay has posted an incredible video explaining how a lawn mower cuts grass. It is way more interesting and memorable than you might think. The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even. The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera. Highly Recommended to watch and subscribe to SmarterEveryDay for more great content! -HSC
Smarter Every Day has posted a very nice example video of audio master Gordon McGladdery recording audio to be incorporated into slow motion footage. Since recording real slow motion sound that is usable at super high speeds is an impossibility due to the undiscernable pitch that results from it, you need to get creative with some reverb, echo, pitch, and chamber audio effects in order to get a compelling final product. We are big fans of both their channels and make sure you check them out for supporting them.
