Jello in 7D looks ... kind of the same

Hmmm...

I was hoping they improved the shutter read/reset time just a weeee bit on the 7d, but strangely, it looks about the same as the 5d,

This is judging from the one clip on DPreview, and I was just sort of frame by framing through the video and noticing distortion....

I had a dream that the dual processors would erradicate jello to at least a RED ONE level...



I'm quite happy that there are actual drop frame framerates!
 
It's really early and we need to see more clips and obviously some A:B stuff but to me from the 4 clips I've seen (all handheld) the CMOS skew seems better, I could be wrong but that's my gut reaction.
Either way 24p and $1699 makes me RANDY!!!!
 
The skew seems better. The shot of the woman on the train, you can see the trees in the background are tilted, but I have taken similar footage with the 5D, and it seems like its been improved.
 
Just watched Line of Sight and there are a couple car mounted shots on and in a rally car and the CMOS skew/jello looks an ass-load better! Now is it a big ass or little ass, time and more clips will tell.
 
Yeah, I'm feeling the same way after seeing those clips....

on other Jello notes, I processed out a bunch of clips using THE FOUNDRY's rolling shutter plugin...

Really helps to 'solidify' those micro-jello-ey clips you get when shooting longer primes...

I think the 7D's 23.976 framerate and some love from the Foundry's rolling shutter should produce just about the best VDSLR work to date...
 
Not sure, I just didn't notice that much jello in these examples. Don't think it's going to be a massive problem if you're shooting properly... only my opinion though.
 
It's probably not as minimal as in the GH1's 720p mode... But even hand-held, run-and-gun shots on the 5D can done such that the jello isn't very noticeable (to the vast majority of viewers).

Train in "The Passage". Rally and moto stuff in "Line of sight". Both these clips should give you a decent idea of how good/bad rolling shutter is.

The moto & car stuff in "Line of sight" looks impressive. The improvement of the train's skew didn't look that much. Maybe the latter was shot at 1080/24p and the other one at 720/50p or 60p which should give a big improvement over RS?

A bit off topic: The dynamic range of the footage looks reduced compared to the 5D and the noise in low light looks a bit stronger.
 
If by "stronger" you mean "better" then I agree. I also agree, based on those two fiklms, that the dynamic range is not quite like the 5Dll's. But I guess we'll wait for more footage to surface. If I remember correctly before Vincent lafl""" video there was a lot of BAD 5Dll videos surfacing.
 
I had an interesting experience last night when viewing the canon footage with my fiancee. I thought the footage looked great, but she said it had something unusual going on - that it looked very "video". I questioned her further and she said it seemed like a lot of the motion was jumpy or kind of floating. It lept right out at her as something wrong, but she couldn't quite describe it. I showed her one of the D90 jello video and she noted that the same effect was in the canon footage, just not nearly as bad. I showed her some GH-1 footage next and she noticed it there, as well. She said it seemed to be roughly equivalent in magnitude, but was less noticeable due to the "softer" GH-1 shots.

All of this while I struggled to make it out. It seems that the jello effect is not seen by all the same way. Any ideas as to why it is so obviously apparent to some and nearly invisible to others, both looking at the same footage on the same screen?

I think we're all very prone to looking for jello now, whereas the general audience isn't going to notice or be as critical. I know when I first saw D90 footage I didn't know what the jello was. I had to look at some of the worst footage shot on the camera and read more to figure out what everyone was talking about. Then it became very apparent to me.

I kind of agree with her though, there is something slightly "off" with all of these cameras. It's like they have all the properties they should have, (DoF, resolution, quality lenses) but there is is still something missing that separates their look from that of a traditional Hollywood film. I think it's the movement. Even at 24p it still feels like it moves differently then a regular 35mm movie does.

That's the thing that got to me - I've been looking at all this footage for quite some time now and last night was really her first time sitting down and looking at technical issues.
