I have a 5d mkII, and am enjoying making short films. I had two accepted on SS and Fotolia, nothing to be proud of but a beginning ;).

Can anybody explain how to do slow motion film? It look a lot of fun. Is it the software or can my camera not do it at all?

If you want to do slow motion you have to have a camera that can shoot faster than regular motion.  Generally shots are made at somewhere between 24 or 30 frames per second (fps).  The canon shoots 30 fps I believe.

So no, you can't really shoot a slow motion because the 5D mark II can't shoot faster than 30fps.  You need a 'high speed' camera which can shoot 3000 fps or something.  There are some point and shoots that can do this albeit poor quality and some very expensive film cameras that can also do this.

You could shoot at 30 fps and then drag the time out to make it play back at 10 fps, or 3 fps and your software would fill in the rest (bringing it back to 30fps) but quality loss would be significant.  It would be good enough for a home movie but probably not good enough for stock.

Here is a little slow motion I took of a 'Norwegian tradition' of smashing the ginger bread house after christmas.  That one I just told the software to play it back at 1/10 the speed or something.

Thanks for your replies.
I don't think I will be paying out $100,000 for a camera in the near future! ;D

I was very interested in slow motion video so I asked for price for a HD camera. Basically from $180.000 I can buy 2 things: a big mac and the slomo gear :D
$111.000 the camera, $40.000 the memory bank, and $30.000 the other stuff, lenses not included (f-mount)
So I decided to wait a little bit for the prices to go down. Seriously. With the current technology advance, prices must go down to $25-50k. Standard definition cameras are far cheap but the future's standard is HD, no question about.

What about the RED One? It makes 120 frames at 2k. The Epic will do some more frames...

depending on how complex the subject is you could get away with shooting 50/60p HD and twixtoring it.  i dunno if that's acceptable for a buyer though.  the casio can shoot 300fps, but its res is too low for any quality use.  now that was a fun camera to shoot with for slow mo for fun though.

I can see the morphing between the frames.  Cool example though.

The  clips is cool no doubt. Not good enough for stock though due to the morphing like Sean already said.

However, the jumping scenes (from the roof) look pretty darn good.

The water splashes show the cheating with the morphing though. I think nobody with an untrained eye would care.

Great solution for low budget directors to create stunning effects.

You expect to see Lindsay Wagner jumping behind him in an attempt to save the world...

I think Twixtor does a fantastic job there. The quality difference is so marginal (it is there of course...) compared to the incredibly expensive super slo-mo systems that you have to get, not to mention the mountains of data to edit...

Well, you've got large shapes moving in a somewhat linear fashion.  With the splashes, there's tiny bits moving every direction, which makes it more obvious.

Looks like the Sony NEX-7 could have 120fps for 720p.  That could be good, hopefully available before the end of the year.  No doubt Canon are also working on more FPS.  Every time I buy a camera, something new comes along :)

1. about the camera used for the video of "Super Slow-Motion Camera Catches a Wave"
http://www.wired.com/gadgetlab/2009/05/supercam/

2. I thought that this was the top
1 million fps Slow Motion video of bullet impacts made by Werner Mehl from Kurzzeit

3. But trying to find the fastest camera , I found this article
http://news.softpedia.com/news/Fastest-Camera-Takes-6-1-Million-Shots-per-Second-110505.shtml

hope you find it interesting


Love that stuff - saw the bullet footage before and it's awesome to look at what happens when a bullet hits an object.

Love this statement:

... According to the experts who created it, the machine's shutter has a speed of 440 trillionths of a second, an unbelievable value, considering that light itself, traveling at the speed of, well, light, only goes a fraction of a centimeter during this time interval. ...
