Between the EX1 and the Canon 7D, which one would you choose for weddings and features and why? Thanks for your help.

[mike24p]

depends. I think you will need two or 3 cameras, esp when shooting 7D's to pull of a pro wedding shoot. If you have enough light, the EX1 and a b camera (could be 7D for low light) probably the best combo

I have a 7D, but seriously, if you're going to be making whip pans of this nature you're not going to us any DSLR. The right tool for the right job. I only bought the 7D because I can change the lens and I needed a new still camera. I love it, but would never use it over my EX1 or HVX200 for creating really usable video. Use a hammer to hit the nail, not a screwdriver.

[mike24p]

the idea was to amplify the jello effect, who on earth would pan that fast, you should give it a shot, 7D video mode, of course it has its limitations compared to the EX1 and HVX200 but beats both when it comes to low light video.

I'm so glad you posted this footage!!! Ok another question: is this footage slowed down, like, were you whip panning super fast, and then slowed it down quarter or half speed?

Because the panning left to right is very slow and in this video and you wouldn't expect this kind of jumpiness.

[mike24p]

the speed is 100% (30fps), just the panning speed itself changed during panning. it was shot at 30fps and the final output is 24fps and its causing the choppiness.

1/80 shutterspeed is your problem. Set your camera up properly (1/50 for 24/25fps) and you won't have such a problem.

@MortallicA91 dont get a 7d if you going to spend that much just get a 5d

[drijfkip1]

The framerate conversion is much more annoying than the rolling shutter efect...

[MaSSiVe0101]

There is something wrong with your settings in this video.. Too much stutter, your frame rates don't match with Final.

[xiawei7909]

Also for motion pictures you need some blur and this is why usually only two times of frame speed is used for shutter speed.

[xiawei7909]

The reason why the faster shutter is not always better is because after a certain time if shutter speed is not multiples of the the frame rate they will be out of sync, which means the whole sensor will not be exposed for the same duration at the same time while the sensor is scanned from top to bottom, which causes the rolling shutter effect! Please correct me if I'm wrong. 

[bnccristi]

you need to follow the 180' rule. 1/50 for 24/25fps, 1/60 for 30fps, 1/125 for 60fps. The shutter speed needs to be double the fps. But you can only have 1/50 the closest to 1/48 and 1/125 for 60fps as there is no 1/120 on cameras

@meatball3000 Thanks, buddy. I got a chance to try this out today and set shutter speed at 200 while shooting at 25fps. Worked fine.

[meatball3000]

@vishalkhanna19 A faster shutter speed might help but you still want to keep it in multiples of double whatever your framerate is.

[vishalkhanna19]

@meatball3000 Wouldn't a faster shutter speed be the right solution?

[msscreenwriter]

Is that Brooklyn, or the lower east side?
