Jittery Pans

I am having trouble with panning my HVX200. I shoot at 480 i 30p. The pans look jittery, almost as if they were strobed. Zooms look fine, just the pans look bad. The pans were smooth when I shot them--that I am sure of. They just look jittery on playback. Anyone else have this problem? Would another setting prevent this? Thanks!
 
could you elaborate about the OIS? I mean is this a setting, problem with the lens/camera?

in addition, if your shooting 720/24pn i know not to pan any fast moving subjects for this same reason.

What is the best way to shoot using the DVCPRO HD codec 720p/24pn and get a smooth panning, say recording people walking/dancing/bike riding..


thanks~
 
OIS is the mechanical compensation for movement while doing hand held work. It should be shut off while on a fluid head.
 
When you pan an old rule of thumb is to make shure a object take 7 seconds to go from one side of the frame to an other.

Yeah, OIS = Optical Image Stabilizer.

Lower end cameras sometimes use a (much worse) electronic version: EIS

I've had this same problem.

But what's the solution if you wanna shoot a 720p/24pn project? I never see this issue with professionally shot projects. What is that they do to avoid this?
 
When you pan, keep the subject of your pan (i.e., a person walking) in the same part of the frame the entire time. This draws attention to the non-jittering subject, and draws attention AWAY from the jittering background. Other than that, pan slower or decrease your shutter speed. shutter speed wont help as much as slower movements and maintaining frame position for your subject will.
 
Using 30P, you will still get image judder during moderate to fast pans.
24P is only 20% slower frame rate, so it would take only a 20% increase in motion
or pan speed to have the same judder effect as 24P.

Use interlace if you want the liquid (reality) look, or adhere to 24P framing and panning techniques.

Or maybe it's something else. :) and you are working correctly with the progessive format.

Woops, sorry R Gale got their first. Agreed!
 
I totally third that comment. Go watch a film in the theater, and just focus on a corner with no subject during a camera move.

You might be comparing 24p with DVD's 24p (which uses pulldown), which is why your 24p footage won't look like filmed stuff on your TV until you add pulldown or write it to DVD.

Playing with shutter speed will change motion blur, which might help you smooth out things if you want. Or give you the "Saving Private Ryan" effect.

I notice it all the time in movies now that I've been using 24 fps for a while. Also keep in mind the finished product for some reason comes out smoother than what you see in the viewfinder/LCD.

OIS however makes pans very jerky. It's turned on in the cam by default so make sure you turn it off before shooting.

could you elaborate how this is donw for the sake of the conversation? And by doing this does it effect anything else? Just curious..

Thanks in advance!

Two thoughts:

1 - the strobing in the viewfinder or LCD appears much worse than it actually is. The end product always looks smoother on a TV.

2 - Watch a TV show or movie shot on film and you'll notice it. Since getting an HDTV I *really* notice the strobing. And I'm happy to say it looks the same as my HVX 720/24pn footage!

And you are turning off the OIS as others prev posted? If you are turning the OIS off can you add as to how you turn it off? It is understood that the OIS is on by defualt when you turn the hvx on.

thanks for the post.
