Canon’s DSLRs come with a variety of continuous shooting speeds, ranging from 2.5 frames per second on the 300D (AKA Digital Rebel/Kiss Digital) to a whopping 14 frames per second on the high-end 1D-X. If you want to get a taste of what these shutter speeds sound like on the actual cameras, check out the comparison video above by YouTube user dochero2005.

Earlier this year, we shared a crazy example of how you can make water drops look like they’re frozen in midair simply by passing the water over a speaker and using sound vibrations to sync the drops with the frame rate of your camera. Well, Japan’s largest music channel, Space Shower TV, has taken the idea and turned it into clever commercial. What you see above is ordinary footage using this trick — there’s no fancy CGI trickery, reversal during post, or high-speed camera footage involved.

Here’s an old-ish video that’s been making the rounds again lately (viral videos are like viruses — they don’t go away very easily). Titled “Camera shutter speed synchronized with helicopter blade frequency,” it shows what can happen when your camera is synchronized with the RPM of a helicopter’s rotor blades. The resulting footage makes the helicopter look as though it’s just floating in the air!

A couple weeks ago we shared an interesting video in which a speaker and Canon 5D Mark II’s frame rate were used to make water appear to be frozen in mid-air. This new video by YouTube user Brusspup takes the idea to the next level by making the water appear to travel upwards. He explains:

Fill a bucket full of water and place it about 5 feet off the ground. Place a subwoofer about 1 foot lower than the bucket. Run a plastic tube from the top bucket down in front of the subwoofer. Tape the tube to the front of the speaker. Then aim the end of the tube to an empty bucket on the floor. Get the water flowing from the top bucket. Now just generate a 24 hz sine wave and set your camera to 24 fps and watch the magic happen. Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to “move backward” or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly forward.

This experiment has become quite a trend as of late — this particular video has been viewed over a million times in less than a week.

When recording video, a camera’s frame rate can produce some pretty strange effects. If matched up with a helicopter’s blades, a helicopter looks like it’s hovering in midair with motionless blades. YouTube user mrbibio found that the same thing can be done with falling water. His technique is brilliant: by pressing a water tube against a speaker, mrbibio was able to control the vibration frequency of the water flowing through the tube. He then adjusted the pulses of the water to match up with the frame rate of his Canon 5D Mark II. The result is a video of the water looking as though it’s frozen in time.

Canon’s new 1D X DSLR shoots at a whopping 14 frames per second, but did you know that it’s not the first Canon SLR capable of that frame rate? Nearly 30 years ago, back in 1984, Canon unveiled the “F-1 High Speed Motor Drive Camera”: a camera powered by huge battery packs that could chew through a roll of film in 2.57 seconds.

Here’s another beautiful example of what Twixtor, the $300 frame-rate conversion software, can do for footage captured with ordinary cameras. This one was shot with the entry level Canon 550D (i.e. T2i), a Canon 18-55mm kit lens, and a Sigma 70-300. Though motion approximation can present issues such as warping, this kind of software is a good alternative for people who want slow motion but can’t afford to rent ($2,500/day) or buy ($118,000) a Phantom camera.

If you don’t have the $2,500 needed to rent a Phantom camera for a day but would like to have super slow motion in your videos, you can fake the effect using special software designed for the task. The above video by Oton Bačar was recorded on a Canon 7D at 60 frames per second, but was slowed down to mimic 1000fps in After Effects with Twixtor, a plugin that allows you to speed up or slow down footage smoothly. It uses warping and interpolation to provide smooth results, avoiding the choppiness that you see when you play normal video back in “slow motion”.

Too bad Twixtor is still pretty pricey — a license will set you back a few hundred bucks. Does anyone know of any cheaper alternatives?
