D300s Jello on youtube

Matt, what format are you shooting? I get rolling "scanline waves" when shooting 24p at 1/50 using my EX1 (CMOS)

under 50hz lights? sorry but that's physically impossible. you must be mistaken or there's something wrong with your camera, or maybe it's simply not exactly 1/50, just as 24 is really 23.976? i mostly shoot film in 24 fps but also the d90. i've hardly ever shot 24p "video".
 
My local camera store(northern New Jersey) has 3 D300s in stock but is not going to put one out for demo so I was not able to look at how the video mode works. Anyone know for sure if the exposure values are real in movie mode?
 
That is not the "jello" we have come to dislike so much on the D90. That is the usual rolling shutter effect of the cmos sensor on movie mode. The same happens on the Red One if you jerk the cam around sideways like that. The "jello" effect happens when you tilt the camera top back and forth even so slightly creating an image that looks like is underwater. If people don't even know the real facts how can they become "experts" on a subject matter. Experience the camera firsthand then you'll be able to make at least a knowledgeable contribution.

Agreed -- it's a tool, and all tools have their strengths and weaknesses. I'm sure you can shoot beautiful video with the D300S (the Ami Vitale video pretty much seals this case). Just don't expect to shoot the next Bourne film on it.

It looks to me like they've made improvements with D300S video. It isn't "all the way" there yet (neither is any other DSLR, for that matter), but it's impressive, and unlike the D90 it includes a mic input. Progress...
 
i never understood why people feel the need to make comparisons between what pros can do with one camera and an amateur with another, then jump to the conclusion that the "tool" is "just" that. wouldn't it be more interesting to compare that same amateur shooting with one lousy and one great camera, which will produce better pictures? if the great camera fails in that test then i will dismiss it as tool no problem. the way i see the "tool" thing is that there's always a better camera for the task at hand, one is smaller, one is sharper, one has higher iso, one takes cool gritty or soft pictures, one shoots high frame rates, and so on. it does not mean that the camera doesn't matter.
 
I tried the D300s in Photografica (Copenhagen, Denmark) last monday. And I honestly didn't se much improvement. But what I did see in the files I brought home was that they seem a bit sharper, and yes the jello is mildly improved.

I'm gettin' the D300s but not so much for the video upgrade (already got the D90) but more for the stills upgrade, and upgrade in build. I hate using that toy-like D90.

I think you are out on a limb here, trying to claim proper definitions of slang. "Jello" is slang, not a precise technical term.

I used jello instead of "rolling shutter skew". I'm not claiming "jello" is the correct technical term but it seems to have become the common and easy way to refer to trouble regarding rolling shutter CMOS.

What you describe happens to all CMOS video cameras, including the RED ONE, not just the skewing.

What you refer to as jello is produced from the very same traits of the rolling shutter (scanning from top to bottom), and quick pans are the easiest way to reaveal the speed of the rolling shutter. You should be careful in criticizing "experts" if you are not an "expert" yourself.

I am not reviewing the camera. I just saying "this video shows the level of jello (or rolling shutter skew, if you will) that the 300s produce." I don't need firsthand experience to see that. It's evident from the video.

As I told Zim:

chagchag said:
You are missing the point here [...]: The guy jerking the camera does not try to tell us a lot about the camera. He is jerking the camera to see how bad the jello is. No more, no less.

I'm repeating myself, I know.

The " 'nuff said" bit seems to have been causing a lot of controversy, I'll be more elaborate the next time.

What I should have written is this: "This video illustrates the level of jello in the D300s video. Now we know, and no longer do we have to speculate to what extent Nikon has been able to reduce this phenomenon. However feel free to discuss it.".

I agree completely. We all know the finished work is what really counts, but as craftsmen/-women we care about how we get there. What we discuss in these threads are technical traits, abilities and limitations of cameras. When we discuss technicalities we are dealing with technicalities, not artistic value. We want different tools for different jobs. But we allways want as much as possible for as little cost as possible.

My old D70s is doing weird stuff. If the photography end of the D300s turns out pretty good I'll buy it for that alone. This camera will sell like crazy just from the photo people. I think the video will be ok to0. I don't swing my video cameras around anyway. The auto focus at the end of this video seems to work.

If I could get video like Ami Vitale you guys can wait on the 7D.

Zim, swithching from a D70 to a D300s will make you VERY happy. They are lightyears apart. I shoot a D3 and a D300s and love both. The D300s seems to have improved on most of the things I was hoping they would improve on the D300 (though the D300 is still GREAT).

If you want to shoot video's like Ami, then it's a no brainer. You certainly can shoot videos like that with the D300s. Heck, you can shoot video like that with the D90.

If you want a camera for the stills part alone, I would go with the D700 over the D300s.
 
same here. Unless I hear something bad about the D300s in the picture taking side I'm going to get it too. The D90 had a lot of good films made with it. Like the one Zak made. I'm sure the D300s will too.

I have a D200 also and I'm guess the D300s is going to be improved a lot from that too. The D700 would be nice but I think the price jumps to much. Plus I do want the video.
