5D II - Youtube footage - Not MUCH Skew... Hmmm

I don't know, I'm imagining that this is just a guy with a blog who went to a camera show in Lisbon, shot to his own card, and then put the footage on youtube.... I'll try translating his website, (linked in youtube)

But as a d90 user you must agree, Kholi, that this exact operator would have killed the d90 as far as skew goes.. so it appears there has been some progress
 
I wonder if he shot 1920x1020 or if he used the lower resolution setting (640x480) which might have some impact on the skew. If this is Full HD then the skew is nearly non-existent! Put this baby on a steadi-cam or tripod and you're OFF!

Crap - there goes $2700 from me... :-(

He also was on a wide lens and without much fast panning. I want to see somebody swish panning back and forth to see how the two compare.
 
there is no difference between wobble and skew. it's the same effect called rolling shutter

it rolls but less than d90. that's pretty clear. what we need to know is what sort of controls are available in video. so far we now that you can't set the shutter but no indication on locking exposure or other things like EV
 
My mirror post on REDUSER got slaughtered in the "is there skew to you?" question.

Compared to the d90 though, this is looking pretty good.
 
I also just noticed a moment where the guy panned out the window, and there was a very smooth transition to a lower exposure... that was nice to see as well.

I would buy this over a Scarlet if all the manual controls are there, and the sound is there a bit more...
The thing that gets me is the apparent FIXED BITRATE! Even on the sample clip at DPreview, a bird with a very blank sky in the BG, the compression stayed at the target level! Oh Nikon, if only you were so diligent...
 
How can we be 100% certain that youtube video is actually from a Canon?

In case it is, then it does represent almost zero skew (although, the pans were not that fast, but at that same amount of handheld operation the D90 did show effects of skew)

I know it's caused by the rolling shutter. But when you look at D90 footage the RS results in two things: Vertical lines become not-so-vertical when panning, but if you shake the camera (even ever so slightly) up and down, the image 'wobbles'. Hence why I talk about both like they're two separate issues.

the wobble is when you move quickly left-right
the skew is when you move only to a side

the same thing

get the movie in the link above
it has rolling as wobble. it's not much but it is. also it isn't very sharp. like d90 it seems they read only some lines from the cmos. it's really not 1080p as you know 1080p

the colors are freaky and the camera is on auto

photos are ok below iso 3200 i think. above... well it's 21mp...
 
I think it's likely that the 5D MKII will have roughly the same amount of rolling shutter issues as their consumer HD cams. (HV30, HF11, etc)

While not ideal, that would be a decent start.
 
here is 100% crop from the movie

i couldn't find too many sharp frames. the guy moves a lot


the DR is one of the most strage i've seen.
don't know what a user could do to get that since the camera adjusts itself, it's on auto mode
also there some color banding going on
 
My impression is that skew is about the same as D90, but there is less jello-vision. I'd probably attribute that to better optical image stabilization, but who knows. I haven't been using my 1 VR lens because the focus ring feels like poo.

I do like that they got the jagged lines fixed, strong lines look nice, without the bizarre aliasing I see in my D90.
