Jello vision?

Many people worry about rolling shutter problems, few are seriously affected. JelloCam seems to come about with high frequency vibration. It is quite difficult with a camera as heavy as an EX1 to shake it that fast (relatively easy with something like a canon HV20), and sensible measures to stabilize the camera will probably eliminate that concern.
But if you are shooting cyclists going round a track at speed, you will get background skewing.
 
Hi everyone Im new to this thread. Erm was interested in this rolling shutter issue and I dont know if this has been answered and I might seem like an idiot but would a tri cmos sensor have the rolling shutter issue?
 
ok thanks was looking into the panasonic sd100 and the canon hv30 to buy, think I might aswell go for the hv30 (25p and all), just though if the panasonic had eliminated the rolling shutter then that would be the one to go for.
 
correct me if i'm wrong, but the ccd is a smaller sensor, so it can read faster and eliminate the issues that cmos faces with jello - ??? and cmos sensors are larger so you get shallower depth of field - ???
 
CCD never has jello because it doesn't use a rolling shutter. It has nothing to do with the size of the sensor. Today's CMOS sensors use a "rolling shutter" and that can lead to the jello.

CMOS sensors are not larger by default; there are plenty of 1/3" CMOS sensors around, and plenty of gigantic full-frame 35mm-sized CCD sensors.

The Sony V1U is a 1/4" CMOS which competes pricewise with the 1/3" CCD Canon XHA1 and Panasonic HMC150.

The Sony EX1 is 1/2" CMOS, but apart from the Sony XDCAM-HD lineup there aren't really any 1/2" CCD cameras on the market anymore. There have been in the past (like the JVC DV500 and Panasonic DVC200?) but everyone has pretty much abandoned the 1/2" market except for Sony.
 
the ex-1 definitely has skewing if you pan somewhat quickly. most normal and non whip type of pans never show up as anything that would grab your attention though. plus many times you dont have obvious vertical things in the background to illustrate the skew.

the EX series cameras are not very good for most sports IMO. mush and swish is the best way to describe it. for instance...if you follow a soccer match, of course the direction of the gameplay is changing constantly and very quickly. i find the results horrible and really not usable, but...if you are following a player and he is moving with your panning then he is decently "sharp" but of course the rest of the contrary movement is still swoosh city.

luckily i dont shoot sports for a living so although i was a little disappointed with the results i am still very happy with the EX1.

for most types of shooting i find the camera mostly "stunning". much of the work i do which is music videos / live bands it works great. other stuff like events, its is also great.

for the most part...forget whip pans except for an occasional effect and in general you have to keep reminding yourself that you need to keep your panning speed conservative.

some pluses are that you can use the gain boost with very good results. going to +12 is not much of problem to me if i need the boost. i was shooting my kids skateboarding (they sure love the creamy slow motion) the other day towards dusk and had to go to +18 and it still looked pretty darn good.

another plus is the way it renders highlights. stage lights look amazing giving you a very sweet "poof" and almost a star (5 or 6 points) of a spill outward from a light source and overally very smooth in tone when shooting into bright backlit scenarios. pretty impressive to me

its a killer camera...except for sports type of motion.

good luck

Hi David:

Nice footage but I see skewing in the first shot after the logo and in most of the panning shots that have the palms or hotel buildings in them as you track the planes. It is subtle in your footage, not nearly as bad as I experienced shooting baseball at 60 fps on the longest lens setting but the artifact is definitely present in your footage, although if you were an average viewer, you probably wouldn't notice it in your shots.

On the video sample, the distortion is not very visible. I would say the shuttering looks a little unnatural but there is not much skewing.
 
He obviously used a fast shutter for that stutter staccato look.
I liked that look for the air show. This would be a good look for recreating
old air combat dog fight.
