7D Native File at 60p...

Whew, much more aliasing than I expected. I hope some settings tweaking can reduce that. Can you post some straight up 1080p24 footage?

Thanks so much!

It seemed to me that the aliasing was most evident in the fringes of a fisheye shot. I wonder if the lens distortion might have contributed to aliasing?

i.e., the top edge of the concret jump didn't show any aliasing at all (to me) until the end when the camera tilts down and places the top edge of the jump in the upper edge of the shot where the fisheye is distorting the most. That is where the aliasing shows up to me. Objects...even hard angled lines...don't show much aliasing when they are in the center of the shot.

Craig thanks for putting this up. Nice action shots, but they do reveal the aliasing problems with the 7D. Wide shots, lots of horizontal lines that are not straight/linear, looks like they might mean trouble. I do think the perspective (rather than distortion) of the wide lens contributed to the aliasing.
 
Please remind me, does the GH1 have the same alias problem?

Also, boy does my 2005 Powermac G5 Dual 1.8GHz NOT run this file smoothly. I conformed to 24p using Cinema Tools and it was a bit easier to play without frame skipping.

This really makes me want to try some native GH1 files at 60p.

For my needs all I want is 60p->24p at 720, and something that I can't edit on my current mac. Anyone advise me to get the lower bitrate GH1 instead?

I just uploaded this for a mate so if you guys want to see a native file off the 7D at 60p then download it here...

Thx for sharing Craik. I felt free to do some grading + slomo testing with this native clip. I hope you don´t mind the uploading on yt (otherwise let me know): http://www.youtube.comwatch?v=x2RT4b-JPGQ
Could you please make a short aliasing + moire test? Just put your d7 on a tripod and shoot some architecture - same scene with 1080p24 + 720p60? That would be nice...

That's some fancy grading. How would I do the same, if I wanted to bring the clouds out like you did?

That was all done in Photoshop - played around with blend modes, gradient, hsb... etc.

But aliasing/moire has been a frequent complaint about the 5D, so it's something I looked at on the GH1 and didn't find it.

Barry, you´re kidding - right? In 1080p24 mode you find a awful lot of aliasing. Sure, in 720p60 much less. Obviously, its just the other way around with the 7D => in 720p60 more than in 1080p24 mode.
