Super Slow Motion with 30fps
Posted by Faraz Mozafarian on March 1, 2011 at 8:18 pmHi,
I have seen some videos recently where people have somehow created very crisp looking slow motion shots with 30fps footage. I mean it almost looks like they used a high speed camera. How do you achieve this without getting all the frame blending you normally would get?
is there a special filter or something?

March 1, 2011 at 9:00 pmI have the raw footage that was used in the commercial. It is 29.97. I mean the footage is obviously not as crisp and clean as a high speed camera but still is way better than what you would get by just simply using Final Cut or AE’s built in speed tools to slow it down.
Are you sure there is no filter or cheat that was used? I wish I had the actual commercial handy to post but I do not at the moment and I do not have the editors contact info to ask him.

March 1, 2011 at 10:04 pmNo the footage was shot at 30fps. Using an old Sony HVX2000. I’m pretty sure those cameras are not even capable of shooting higher that that.
That’s why I am so puzzled as to how the editor got the footage to look so crisp.
I found the edited commercial. I will post a preview of what I am talking about so you can see how slow he got it to look.

March 2, 2011 at 1:58 amHere are the specs for this specific clip. I also have seen this done with footage shot at 30fps.
1920×1080
CODEC: HDV1080i60
FPS:29.97How did they do this? It looks almost warped in some areas. It’s hard to tell in this flash version but there is little to know frame blending at all. Looks like it was shot with a high speed camera.

March 2, 2011 at 2:13 amNo body is pulling my leg. I have the raw clips here on my hard drive which I personally gave the editor. I am 1000000 percent sure it was not shot with a high speed camera. 60fps at the VERY most. I know the person who shot these clips personally. He could never afford a high speed camera. haha.
It looks like it is some very clever work in After Effects. Maybe some rotoscoping, mixed with a warp/distort. I just would like to know how it was achieved.
But please believe me when I say that this was NOT shot with a high speed camera.

This effect could actually be done with some clever use of stills. See the tutorial 3D from 2D Image using Displacement Maps [link] by this forum’s own Tudor “Ted” Jelescu.
Warping (I call it “blobbing”) is a typical artifact of motion compensation. Twixtor can produce some great slo-mo effects, especially with the Pro version and its advanced features like foreground separation and track point or spline guidance.
As Dave was saying, though, shooting 720p59.94 (which nearly any 720p camera can do) and reconforming the footage to 720p29.97 gives you an instant and perfect 50% slo-mo. It’s great to use as-is, or as a starting point for further slowdown.

But I think we’re gonna need to see more of that footage to make a proper analysis 😉

March 6, 2011 at 4:01 amI’m willing to bet money on that video being made from a still image using the techniques mentioned. You can see the footage is ‘warping’ rather than actually moving naturally.

Why don’t you just ask editor?
