Post Slow Motion with a DSLR?
Hi Guys..
How would you get a slow motion scene by just using a DSLR (not video) Would you have to take rapid shots of the same subject IE a bird in flight???? Or could you do it by shooting a scene for time-lapse and slowing it down in editing???
Any suggestions
Take care, Lance.

Hi Lance,

I'd doubt you'd find a camera that can do that sort of rapid fire. Ideally you'd need at least a 200fps video camera but all depends of other issues as well eg. frame size and quality ? Yes you could slow down the video footage as well but anything beyond half speed is noticable.

Hope this helps.

Steve R.

You can shoot at 60fps and then convert to 24 fps (2.5x slower), but most DSLRs shoot 60 fps at 720 resolution.
Later you can use special software to slow it down even further, that's what I did to produce this short clip, it slowed down 5x.

That works quite well spider77.

How much more did you slow the footage down by ?

I shot this in 60fps, then converted to 24fps (2.5x slower) then I have slowed it down again 2x (overall 5x) using free plugin for VirtualDub called MSU Frame Rate Conversion. Here is a link to tutorial how to install and use this plugin http://youtu.be/ypWQCcINQIo

Time lapse compresses time by refusing to pay any attention to the time that passes between widely spaced exposures. When an hour's worth of time lapsed images are played back at a normal frame rate, stuff moves quite rapidly because the intervening time has not been captured (or has been discarded).

Slow motion expands time by slicing short lengths of time into many distinct images, each separated by tenths or millionths of a second. When played back at a normal frame rate, each second of camera time is displayed for many seconds of screen time.

For many years, Sony' slow motion video systems were used during the broadcast of baseball games. Those systems ran at only 90 frames per second, three times broadcast frame rate, but the cameras were using short exposure times, like 1/000th second, to freeze the image. One could count the threads on a baseball moving at 90mph if the camera was in focus.

The highly specialized and very expensive Phantom cameras capture many tens of thousand of frames per second to computer drives.

Most of us consumers can hope for about 200 frames/second with conventionally available equipment.

Casio EF-X1 shoots 30 frames per second video with a mode that can go to 300 briefly and back to 30. Awesome "she just came into the room shot".

It also does slow motion. At 300 frames per second it records standard def video (512 x 384 pixels.
At 600 frames per second it has 432 x 192 pixels.
At 1200 frames per second, it records an elongated 336 x 96 pixel window, which lets you record in a direction of interest, such as where the pieces of something are expected to be going after an event of interest.

You can see a lot of things happening even with so few pixels, and it costs less than the daily rental on a phantom.

Here's a review;

And here's some example video shot with one.

Well if you chose to shoot high speed video then the Go Pro HERO3 Black is a great option from what I have read.

You can shoot 120fps at 720P (1280x720P) - read here - http://gopro.com/cameras/hd-hero3-black-edition#specs
