The question is, how can you accurately preview 24p AND 30p in the same vimeo upload?

Why does it flicker every now and then? That worries me a bit.

It flickers because hes changing his exposure setting with the dial on manual mode (i believe)

You're right, the flicker is from manually adjusting exposure. And yes, doing framerate demos in flash video for the web is not ideal. Hopefully we can have clips straight from the camera up soon.

To be honest you'd have to say all previewing on the web is not ideal. The word accurate doesn't come in to play. It would be nice to get downloads of separated clips. Can that be done?

Have you used the Mark ii ? hows does the 7d compare?

there's gotta be a second test to this. It seems like this person that shot this video has never use video dslr b4.

Could you enable this for download?

Great camera, it seems. But probably when you move up to 1080p regions, the CMOS+rolling shutter will give you the usual headaches.

It’s funny because we are prepping an action flick for this winter that will have some great Manhattan fight scenes and chases sequences. We are actually looking for a NY or Philadelphia based DP, as our previous chap retired, he did not do digital, anyhow. Unfortunately, those crucial fight/chase scenes we will have to shoot on film, or at the very least, on Panny P2 Varicam (CMOS+global shutter). But, we figure on using two or three of these little D7s for the non-critical shots, i.e. when there is no fast camera movement or subject movement. We”l probably use the D7 for 75-80% of the shots, and only 20-25% would be acquired by a film camera or Panny Varicam. It is still a tremedous cost savings, of course. Anybody care to chime in?

And there could be scripts that can be shot 100% with a Cine-DSLR, just not those where there is fast movement by the camera itself or by the subject(s) front of the lens. Too bad, really, but that’s the one major downside with CMOS plus rolling shutters.

Was this shot in New York? Wherever it is, I want to go.

Thank you for uploading. I still see some aliasing, i. e. at the grid in the back. This problem was massive with the 5D, but this should be better here, because of the smaller sensor. What´s your meaning?

thx for the test.

pretty ugly for the 'centre' of the world!

anyway, just to reassure you, the 'centre' of the world is wherever i happen to be at any given time.
at least that's how i see it! :)
if not, it's Sol in Madrid but i'm there quite often anyway.

wait hold on, i just remembered, it's paradise, Celtic Park, Glasgow!

anyway, more tests greatly appreciated!

How long can you shoot video in the 7D?

That's my same question? How long can you shoot video, all day? 2 hours? Thanks.

At 30 fps individual videos can last up to 12 minutes. Check dpreview.com/previews/canoneos7d/page13.asp for more info.

On hot days with no ventilation, your CMOS sensor might heat up inside of 20-25 minutes. First the write bitrate drops, then you will loose entire frames, and finally the camra shuts down cold for a prolonged "cooling-off period."

If you do not have a B-camera that you can continue with, it is always a good time to go to the concession stand for that beer.

These DSLRs were designed for STILL photography, so they do not handle continued operation required for video shoots too well.

Rattle, dazzle, and jerk-jerk-jerk.

**"Looks like 7D will handle video better, with it's 29.97 + 24,25,50, and 60 frame rates. "**

New update from Canon:

5D Mk II Firmware to be updated for 24p/25p and possibly other frame rates?! Video may be just as much the 5D's domain as the 7D's. Plus you'd get the bokeh of the full frame :)
