Jitter!

i really didn't notice any "mad" jitters in your clip. when i think of jittering footage it makes me think that you might have your OIS on. If you are shooting on a tripod then you want it off.

Personally i think that you can get some creative shots while leaving the OIS on. I left my OIS on for several b roll shots for a series of videos and I really liked it. It made it unique and "flawed" which is kinda what i wanted. But in most cases you dont want it.
 
I always leave my OIS on, tripod or not.

But look at the depth of field switch, don't you find it 'skippy?'
 
I see what you mean. It's a good rule of thumb to turn off the OIS when on a tripod. It will cause tiny shakes in the frame if it's on while on a tripod.

...but that isn't your problem. I'm not sure why the focus seems to jump a little bit. Was it just in that shot?
 
in all my shots ....the OIS has nothing to do with it, cause in the 5 months I have had my DVX, i have shot with OIS ON ALL time time, and i have had no problem...You noticed the skip? maybe it's cause i was 1/120 shooting 24pA...I don't knwo...
 
Is this the only time it has happened? Because if it only happened this time, and hasn't done it since I wouldn't be too worried.
I didn't even notice anything until you mentioned it was in the DOF switch; then I played closer attention and noticed that it does tend to 'skip.' Hmmm....
 
I'd be curious to see an example of the slow pans to see what you're talking about.

As far as this clip goes - my guess is that its a combination of the faster shutter speed and the speed at which you're pulling focus. Using the macro probably only exagerates it more. Do you notice this jittering when you rack from things that are further away? (using the longer end of the lens).

You might want to try setting up the same shot and pull focus both more slowly as well as quicker, and see if you notice it in either case. Also try it at 1/48th shutter.

The effect you're getting here seems very similar to the jittery effect you get on a pan when done at an improper speed while shooting at 24fps.
But again - that's just a guess.

EDITED TO ADD:
I noticed you shot 24pA.
Just double checking - but is the clip you posted at 23.98 or 29.97fps?
If the pulldown frames haven't been properly removed from your footage it could cause a 'jitter' in your motion.
 
Guys, thanks...

But Everytime i shoot and edit, I do the EXACT same thing......shoot 24pA, capture it using the 2:3:3:2 pull down removal, edit in 23.98 sequence and it is always fine. JUST this one time it happened, the pan is the worst, Ill upload a clip soon. Im thinking it's cause I shot 1/120...
 
And, on another note, I usually shoot 24pA on a shutter of 1/48 or 1/60. I shot 1/120 cause I had to much light, and I wanted a crushed background, so therefore I left my iris at 0. I needed more light then, so that's why I used 1/120.
 
Well, i think you're probably half right -
It's probably a combination of shooting 1/120 and 24fps.
If you were to shoot that same shot at 60i or at 1/48 I'm guessing the jitter wouldn't have happened.

But - only one way to know for sure.

Next time you might want to use your camera's ND filters instead of upping the shutter speed. That will cut your light without changing the look the way shutter speeds changes do.
 
I tried that Luis, but it cut it TO much. I wish they had 1/3, 1/4, 1/5 options...That'd be cool!

Here is the clip, look at the the 4 things side by side (not sure what they're called) but they are the worst!

Edit- See, doesn't it just hurt your eyes...I hope it's the 1/120 thing, so I know what I d id wrong...

In one of my other shots it's fine and looks great, probably cause I switched back to 1/48.
 
Yeah, that just looks like a matter of panning speed being a bit too fast.
When you up your shutter speed like that, it cuts the motion blur you normally get from a 1/48 shutter, which makes every frame crisp - so the panning is going to have to be slower to make the movement from frame to frame more discreet. Otherwise it looks 'jumpy' like that.

At least, that's what I'm seeing.

Next time you'll either need to slow down your pan speed or lower the shutter speed and compenate by either cutting the light itself or closing down the iris some.
