I was contacted today by Canon 3d line support. This is the specialized video tech dept in Germany.
They request samples of footage that shows problems with the 7d video.
I have a few such samples, but i was invited to do a call for material through this weblog.
People that want to show problematic video stuff to the right Canon people are herewith invited to send me SHORT original miv files, through Yousendit or via a download link. Please include a short description of the problem including detailed settings info. You can mail me at m.beek at maevelsfilm dot com.
I will compile a report for Canon at the end of this week.
Canon is realy offering us a chance to communicate our issues, so rise to the occasion you all!

What is the exact problem you’re talking about here? Could you post your own examples, so I know what to look for in the stuff I shot so far?
please mention the missing option to turn off auto gain for audio inputs!
I’ll post a resume the end of this week, including samples of anomalities supplied by other readers.

Thank you for your input. I’ll compile this all into a email to Canon at the end of this week and will put some files online for their analysis.
I’ll get back to you a.s.a.p.

I’ll compile a wishlist too… 😉

I really hope that one of the samples being sent to Canon includes the moire/aliasing problem. Barry Green posted an excellent article regarding this issue over at dvxuser: http://www.dvxuser.com/V6/showthread.php?t=187503
Yep, the report should cover aliasing issues and overheating problem too (even if it’s already covered on the 7d’s manual)
thank you!
I consider not being able to go down to 1/24 shutter speed at 24 fps and not being able to go down to 1/50 at 50fps a huge problem.
Hey guys,
I’m a total newbie… zero video experience and just got my 7d a couple of weeks. Here’s what i found out….
The same video clips that i took which jerk every few seconds don’t appear to jerk when I play them on Quicktime 10. Tested on two machines…. a Quad core running QT7 JERKES and a MacMini running QT10 DOESN’t.
Can someone out there try this? Tested on 1080p PAL.
Lets get some feedback going!
Dan
I don’t experience any problems in that regard. I have a standard i-Mac 24 inch of april 2009.
