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.
We find that while the video is simple, it does a good job in explaining the methods on Apple’s iOS and Android to get slow motion footage ready for posting on the web or social media. There is some basic editing and trimming for cutting the nonaction parts.

There has been a lot of work put it developing software that can interpolate frames for video editing and compositing applications. Twixtor in the late 90’s was perhaps the first time the technology could make something worthwhile and really produce acceptable results in a computationally acceptable timeframe.
Today the most used algorithm is Adobe’s Optical Flow in Premiere or Time Warp in After Effects which use vector directional plus acceleration of pixel values to derive in between frame data to generate new frame information from the preceding frame as point A and the next frame as point B. The results can do some wonders to really slow down things above the frame rate ceiling of the camera.
Registration has started at Edgerton Center from the Massachusetts Institute of Technology (MIT) for the yearly high speed imaging course geared at the principles of shooting and preparing slow motion setups. The course goes deep into the science and art of slow motion video and has access to some of the most capable high speed gear so that students can use and experiment with first hand experience.
Previous courses have been a great success and the imagery coming out of these classes is pretty jaw dropping. If you can attend the course in June this year it could be just what you were waiting for to jump into the slow motion realm. Access to this gear is few and far between for even experienced personnel and videographers; plus learning from experts in the field can come in very handy to get better knowledge about the process.
We want to share a few videos that explain the principles behind slow motion video shooting. There is a lot of confusion when it comes to slow motion; how to shoot it, how to play it back and the dos and don’ts to get the best footage possible. The principles of shutter speed, light sensitivity, triggering and playback are all based on classical photography techniques with the main difference being extremely short time-scales and the need for inordinate amounts of light… but it can get tricky!
The internet is an information tool that democratizes the ability of the audience to learn and experience new information shared by millions of individuals. Gladly this also includes high speed camera information and sample videos. Be sure to subscribe to the channels behind these videos so that they can continue sharing their knowledge with all of us.
The MIT Edgerton Center is offering a new 4 day in depth course in high speed imaging at their Cambridge, MA Campus. The Edgerton center is as you guessed it the DOC Edgerton building named after the famous high speed imaging researcher and inventor. It is also the main inspiration for the edgertronic high speed camera. It could be a great way to get exposed to the latest gear from the top manufacturers of high speed cameras and learn techniques, lighting for hi speed and problem solving.
