how to get slow mo to look good using 24P at DVinfo.net

Jason Epperson · November 21st, 2004, 10:07 PM

I'm sure this has been discussed many times before, but I would like to strike up the conversation again. How do I take my footage from my DVX100 (shooting at 24P) and apply slow motion without it looking choppy?

I'm currently using FCP 4, but I have access to FCP HD.

Best,
Epp

To sum it up quickly (please continue the discussion in the other
threads, thank you!):

1. the lower the framerate the more choppy the slowmotion will be (so 24p is the worst one to have, 60i would be far better when converted to slowmotion 24p)

2. the quality of doing slowmotion (ie, creating frame where there are none) is a highly complex procedure and varying products have had varying degrees of succes. So it depends on which program you are using as well

The quick fix solution I use... wit some success...
I shoot at 30fps. I slow it down 40% changing it to a choppy 12fps. I duplicate the footage and put it on another layer at 50% opacity. Then i shift it one frame, this give a semi blurred 24 fps look that I like. The numbers can of course be played with and modified. It's just one of the quick cheap tricks I've used and like.

shoot with a higher shutter speed and then when its slowed down it wont have that flicker look, it will be smooth and non-blurred

Heh, never thought about that shutter speed solution. And the other solution is handy as well (mixing 2 videos at 40% op.).

Cool. I am experimenting with this cause you can't have a movie without slomotion really nowadays. It adds so much drama and action to your scenes. Imagine braveheart being edited without slomotion. That would be terrible. Braveheart would be a wuzz really.

I'm sure this was discussed in other threads, but also realize that there are some very cool products dedicated to 'interpolating' frames between the original source frames. Examples are Twixtor and ReTimer. I've had _very_ nice results by using Avisynth and a plug in called MVTools (both free), but it sounds like you're on the mac, so that won't help you.

Check out the demos for Twixtor and ReTimer. "Real" slow motion in film is done by shooting at much higher framerates: 120fps, 250fps, etc. Then it's played back at 24. The key is somehow arriving at a higher frequency of images of the motion than you're planning to play back.
