Yepp, another framemode thread.
I finally got my XL1. I have been doing some test shots just to try it out.

Interlaced mode is quite good. And when I do slowmotion on it, it looks great.

I've been fiddeling with frame mode though. Shutter at 1/50 and 1/100. The thing is, I have to tape some serious fast action
(gymnastics, dance, flips and kicks) And I noticed when you pan or tilt quickly it stutters quite hard. (my opinion) I got some video of people doing flips and they look good when I dont pan or tilt with them.. But when I apply Slowmotion, It gets really bad..

The fun thing is. Real 24fps cameras get less stutter with one less frame. So I think there might be a way to work around this problem. (I'm not talking about slowmotion with real motionpicture fast film cameras - 150fps) I talk about when they do ordinary 24fps they get less stuttering if they film fast moving objects. If I add one more frame I should atlest get close to what they get, but how?

Do you guys have any pointers on how to shoot fast moving objects in frame mode?

The way smooth slow-motion is achieved with film cameras is a technique called "overcranking", where the frame rate of the camera is doubled (48fps) or tripled (96fps) when shooting. When the film is played back at normal speed (24fps) the action is slowed down and appears smooth.

Unfortunately, the XL, or any camera short of Sony CineAltas or Panasonic Varicams cannot be overcranked so you are stuck with having to smooth out slo-mo in post. There are a number of different methods to do this and if you put "slow-motion" into our search function you will find a number of threads discussing them.

You can "overcrank" captured DV footage with either Vegas 4 or VirtualDub. The process re-renders 60i 29.97 fps footage into 60 fps which you can, then, slow down to 29.97 fps footage with very smooth slo-mo. The 60i is converted to 60p, so some vertical rez is lost.

I know all this...

But I'm talking about ordinary mode..

I know all about slowmotion and how it works on ordinary camera, I can do great looking slowmo if I shoot interlaced video.

But I get stuttery feeling when I shoot frame even though I don't slowmotion it. Can I do something about that? I shoot 1/50th..

Frame mode captures two, temporally identical fields every 1/30th(1/25) of a second. Normal mode captures one field every 1/60th(1/50) of a second. Therefore, the temporal resolution in frame mode is 1/2 of what it is in normal, interlaced mode. Unless you do a resample, in which every frame is interpolated, there's nothing you can do to improve frame mode slo-mo's.

I don't have an XL1 but have been reading a lot about it, and it seems that this is because the "Frame Mode" is not true progressive scan, unfortunately you cannot do anything about it, maybe shot interlaced and use the "software" to make it progressive scan and then add slowmotion.

Sorry, don't remember the software name.
