Hi there. I recently bought the v1u and I'm finding that I get a stutter look when panning or when subject are moving fast (I have tried to pan really slow which helps but this is not realistic in the real world). Sort of like a ghost effect. I know that using the dvx before there used to be that when filming but it didn't show up in the final product. What am I not doing? I'm sure this couldn't have been overlooked by Sony.
Sony V1U stutter in 24p

Choopy motion or stutter is a fact and condtion of 24p whether you shoot with film or video. If you shot 60i and then converted a fast pan clip to 24p using a product like DV Film Maker you would see the same effect. If you shoot 24p you will have to slow down your pan speed big time.
You could drop the 24p into a 29.97 timeline and it wil add pulldown that will smooth out the motion. It's not Sony, it's not Canon, JVC, Panasonic, or film it's the inherent aspect of 24p vs 60i.

Post a clip and let's see what you're seeing, but in all likelihood it is indeed as scannon says.
I just learned about pulldowns

Thanks for the replies. I just read the thread about pulldowns and all and I tried it in vegas and it actually helped alot. I shoot weddings and I want to provide the bride and groom something different than the video look. Maybe I'll shoot 30 p as the stutter is significantly less.

Also your shutter speed might be over 1/48th of a second.
High shutter speed + low frame rate = choppy video
Low shutter speed + low frame rate = blurry yet fluid video

Funny thing is I don't see the stutter like some people do. I've had this conversation with people after viewing DVX 24p footage and now with a V1U, it's identical. They see it more than I do. Watch "The Office" on NBC - it's shot with the F900 and designed to be more "video" you'll see the stutter even there when they fast pan. Take even more filmic, dramatic stuff shot in 24p and you'll see it. Take fast film pans from DVD and slow them down on DVD and you'll see it.
The shutter speed issue may also be key as well - either match or double your frame rate and don't go over that or you'll end up with choppy, stacato images.

Personally I'm really coming to dislike 'film look'; I've got to the point where I have a hard time even watching movies in the cinema with stuttery pans.
Somewhere a while back I saw a discussion on the web about how to calculate the pan speeds at which you won't see stutters, but I don't remember where it was. Apparently there's a band between static and infinite rotation where stuttering is visible; go slower than the bottom of the band and you're fine, or go faster than the top of the band and you're fine.

About the fastest that you can pan smoothly is the speed at which an object takes about 7 seconds to cross the screen. Faster than that and you'll see strobing (until you get up to whip-pan speeds, at which point no strobing will be visible).
Changed the shutter speed

Hi. I reduced the shutter speed and the stuttering video or "strobing" has reduced a lot but not completely eliminated. I think after I remove the pulldown, I should get better footage to play with in the end. I also noticed that by reducing the shutter speed, my images have brightened which means better low light performance.

Hulkster,
I'd be interested in knowing what shutter speeds you've been using. And, yes the you're letting more light in so you're images will brighten up.
As for the 24p film look - you can always try to shoot in 60i and drop it on a 24p timeline. I know there have been decent results with that although you may still get some stutter because of the frames that are not being played back.
I have really come to like 30p on the Sony cams. Cineframe 30 on the Z1 was gorgeous IMO and felt very film like to me. It all depends on what you feel is a good look. I think as audiences we've come to accept quite a bit in the sense of different looks just because of all of the framerate and format options available now. It isn't quite the film vs. video look as it was just a few years ago.
I't also makes a difference as to what you're using to show your footage. I've seen really clean material run through nice LCD / Plasma monitors that I know originated on film but looks so nice and clean, it could very well be a toss up between film / HD material. In most cases it just comes down to preference and of course making sure you're still within legal limits of the source media.
