Tips on getting good slowmotion,
 

I need tips on doing a smooth slowmotion. Often It's not that good?
What are the limitations? How much has to be done on the camera?

Edit: I use DV 500, Sony DV Camera and Premiere 6.

I've never figured that part out fully. Thanks in advance!

Well, I've done some slow motion tests (not very much or lengthy)
and it might be wise to use a faster shutter speed to get some
more clarity.

Anyone else has some more ideas?

Do you have them online so I can see your results and what settings you used?

Are there any semi proffesional cameras out there that can capture
more then 25, (29) frames per second?

I don't have anything to show you since I just tested and tried
a bit. Never did keep the results. Sorry.

Slow Motion
 

Howdy. Unforturnately there are several different ways to achieve smooth slow motion playback which means more trial and error. One that is described above is a good start, increasing shutter speed. This is called overcranking the camera in the film industry. If you have ever heard an Arri 435 screaming it's because its burning some major footage every second. When this film is played back at sound speed, it appears in slow motion. As far as your application, I typically choose a clip speed of 65%-75%, mostly 75% and then I apply the flicker remove feature. This removes some of the strobing that may occur. Other than that I think your going to have to spend some more money to achieve that super duper smooth, clear slow motion. Maybe the faster frame rate in conjunction with what I suggested would smooth it out even more.

Im intrested in doing this too. I want to film my dog shaking off water and slow it down. But keep it really smooth. So you can clearly see all the water droplets and everything.

Water Droplets
 

If you want to do that, I would definitely use the higher shutter speed to capture the droplets.

Well, my own thoughts may help too.

I never do slowmotion under 50% and I always turn on "flicker removal" When doing this it helps alot but it still gets blurry and you can see it
doubleing the frames (kind of jerky) It might help if you can use frame mode (I really don't know) But I have not tried the shutter speed thingy yet, It's the only thin I have not tried yet. It's not that I have bad slowmotion but I figure it could be better. I mean if you watch eurosport and it's live they still have awsome slowmotion on the replays (compared to me)

I'm going to try some shutter settings and see what works best.

Thanks all for great responses!

Overcranking
 

James,

overcranking and faster shutter speeds are different things.

You can adjust shutter speed on a DV camera - making it faster will result in less motion blur in each frame, at the expense of requiring you to open the iris to get the same exposure. But you cannot change the number of frames per second recorded (overcranking) - DV by definition is 25fps (PAL)/29.97 fps (NTSC).

When you slow down this DV footage you have to somehow interpolate new frames between the existing ones, and there are many different ways of doing this using NLE, or plugins, or hardware. Typically though, you get what you pay for here - smooth slow motion requires expensive software/hardware.

The only sort of cameras that will give you that crisp smooth slowmo are either film (overcranked) or horrendously expensive Thomson/Sony cinematography/HD jobs:) If you are using DV then you just won't get that Hollywood smoothness and crispness - sorry:)

here's a suggestion that's fairly easy to follow: Vegas Video 3 has a slow motion feature that allows selection of "resampling". This feature interpolates intermediate frames to make the frame rate consistent with the native frame rate of the entire clip. A great feature...and it really smooths out those jerky slomo's.

I too am on a quest for better slo-mo. I use Virtualdub filters and an avs script to double the number of unique frames you can work with. Info for this process is at www.100fps.com.

Hey Bill
Can you give us VV users a quick walk through on how to do that?
I've been just dragging a velocity enveloppe over it and grumbling quietly to myself about choppyness. :) BTW, I'm trying to get about 30% speed.

EZ...

If you right click on the video track you want to resample...select "properties" in the window that opens. Once in the "properties" window, the default tab should be "Video Event". From this window, select the radio button..."RESAMPLE". Also, if you have noticed any flickering in highly detailed frames...like a shimmering...you can select the radio button "reduce interlace flicker" to do just that. It works great.

Good luck.

Bill,
You Da Man!

Overcranking
 

Julian. Howdy. If you go back and read my post, you will see that I said "This is called overcranking the camera in the FILM industry." NOT video. I was just using a comparison of how slow motion is achieved.
