The end of 35mm adapers and hv20s....

Nikon uses auto gain to describe the gain up on aperture and shutter not ISO. .

Do you think then that the wobble, and some of the skew cause actually be being caused by the increasing and decreasing of the shutter speed in auto mode? (If i'm taking what you're saying correctly).

I'm personally betting that there is a setting like 1/60 shutter, iso 100 that keeps the wobble and skew down to a minimum.
 
Just a though... if no one has said so... but the flicker could be from a shifting white balance. I'm also trying to be the first post on the 100th page.

I thought so to, but found out (from helpful other DVXusers) that the rolling shutter is always running at maximum speed. The shutter simply dictates the amount the frame is exposed for, which is simply a differing number of cycles.

Shutter speed should not effect or minimize the rolling shutter, as I once had thought.
 
Iso, won't effect rolling shutter either.


What will effect rolling shutter is pan speeds, and the focal length. Focal length is much like pan speeds because longer focal lengths 'speed' up through magnification.

Poorly explained, sorry.
 
Exactly what I was saying...buy d40...get a HDMI cable...get a HD camcorder....tape....nice tripod...and you have yourself a d90.(dont forget to transfer the tape....and record it in the right formt)

Canon lost some huge battle ground ,as the technology was already implemented in D40,but restricted I assume.

The wave of change brought by Nikon is very welcomed and heavily expected...I just hope there are not going to be any "industry delays" , as many of them will be directly affected.

Kudos to Nikon for making steps of history:beer:



Ps:the white box can be removed in AE.

Hi there,
Lockable exposure or not, doesn't matter now. Clearly the revolution is absolutely here. Which got me thinking: The Canon 50d will have an hdmi out, so I could connect some kind of external hd recorder for better compression right?

I currently own the 40d and I checked:
Yes the exposure is lockable and fully manually adjustable on my Canon.
Is there an hdmi out? no, but wait, there's a video out :P hehe
Welcome to sd filmlookworld. (Has anybody done that already?)

So I hooked the 40d up to my old xm2 and recorded some footage of my cat showing off her powers! Unfortunately I haven't found a way to erase that honky centersquare.

I'd say, seeing what's coming, we've got to hurry and shoot something with the new dslr technology that's going to fall in our laps the next couple of months, before everybody starts doing it!!!

Cheers!

Than how come the shots with a clearly higher shutter speed have no wobble visible?
 
:beer:be the first to hit 100...ehhh...let me open a beer.:beer:

Ieenteresting... very ieenteresting... care to upload a full rez screengrab of that footage? I'd love to see it...

Perhaps a wider angle lens, no strong vertical lines to give it away, slower pans, etc?

Just the operation of the camera. The shutter is always rolling at same speed, and is not effected by exposure.

Apparently the rolling shutter does not capture one frame with one top to bottom roll. It rolls much faster and depending on the shutter speed is the number of cycles recorded.
 
My point is... rolling shutter is the shutter. if it is auto adjusting the speed of the shutter... and that would produce a noticeable wobble.

The big question is... what is the minimum shutter speed to make the rolling shutter not visible. For instance, if the shutter is twice the speed of the framerate... IE 1/48@24fps and if is still visible... that kinda sucks cause.

I always shoot @ 1/60... it just looks cool. Biggest point is that some of the high shutter speed footage doesn't wobble. But I'm also not willing to make Gladiator 2 (the high shutter speed "trick" is overused and hella lame) so let's hope we don't have to shoot at 1/2000 to make this image work.

I understand your way of thinking. I asked this over at the EX-1 forum:

http://www.dvxuser.com/V6/showthread.php?t=145823


It does not work like that. The shutter rolls all the time and the shutter speed is just how many cycles we see. (Really simplified.)
 
How is a rolling shutter always moving at the same speed if the shutter speed is adjustable. That statement just doesn't make sense. The rolling shutter is the shutter... the speed is designated by 1/24 to 1/2000 or however high it goes.
