I'm editing a job now that I shot with the Canon 5D mark II, and i'm noticing that if someone flashes from their camera while I'm filming, often I get the flash only on the top half of the frame...

 

This would mean to me that the camera is not shooting truly progressive frames, and is actually scanning lines.

 

Can anyone out there confirm? If so, really bad...

 

(still looks great though :)

it is called rolling shutter, it scans the sensor from top to bottom, faster than the frame rate but it is still progressive scan.

A rule of thumb is CMOS sensor=Rolling shutter (Sony Ex1, RED camera, Canon 5D M2) the faster "refresh" of the scanning, the less apparent it would be. This is also the cause of the so called "Jello Vision".

They are limitations of the new technology (CMOS) which gives a lot other benefits (less power, less heat, less noise, no smear...) so i think at the end people will just live with it.. and the people that can't stand it will go CCD sensor route.

Hello Everyone...

 

Just finished shooting a corporate video with the EX-1. Nothing fancy, just inteviews and B-Roll of office workers. I found the camera great in general terms. The lens is really nice. Couldn't tweak the image too much, because it is being mixed with footage from SP's from a while ago. It's a shame as I would have liked to try a couple of things.

 

There's just one thing I did not like about the camera, and it is that it doesn't have a proper audio level reading, or at least a did not find it. It is just that small level and the bottom right corner of the lcd. The first day of shooting I had to go to the editing room to take a look at the clips inside the Final Cut to see if the levels were ok. It made me nervous for the first day. Even the one on the Z1 is far better than the EX-1.

Hi,

If you press "Status" just under the top handle it will show some info, then just use the thumb whelie on the back to change screens and you will find proper audio levels.

Hey Andy,

i am very sorry you have to experience this traumatic experience on a shoot.

but if you are not prepared to handle a new camera, or just don't know where the butons are because you wanted to "run through the manual" (not saying that i read one page of it) , please don't post crap.

There is people coming to this forum for info, so your title "My first experience with the sony ex" should be "how to handle a new cam?"

Seriously.

there are ways to control ALL of your "lack of control" issues very easily on the camera, so ALL your problems with te camera are nonesense to the real world.

Yo Guys,

I have developed a good technique for getting the dolly effect, it involves a still camera, After effects and photoshop.

I rigged the still camera over my video camera, then i take a picture when i want the effect to happen.

if you want a dolly out, you should get the closer shot first (with a still aswell) and then go to your wide setup (phisically going, not zooming out) and take another still + your video.

Then in photoshop separate the layers and recreate some background behind the layers, so you will be able to move in a 3d world in AE.

Then match both your video shots with the 2 ends of a 3d animation where you dolly in AE.

its a lot of work, but it looks awesome.

check this video for a dolly in effect:

hi guys

This rig is for NO budget productions, i mean, i spend 28$ on getting a steady orbit shot.

I am not planning to use it in the future, because i am moving on to bigger productions, but i think this concept would be usefull for upcoming filmakers.

The thing is, the tail had beautiful results with 28$ investment... That is why i post it in here.

H

Not bad footage for such a stupid-looking rig. There are far better ways to do that, even on a budget. I wouldn't trust a camera on the thing.

yeah?

tell me one way of doing a 360 stable orbit without budget.

I'll be waiting...

Hi guys

I am in film school now and we have been picked for the final term project to be film on 35 mm and i am the D.O.P

I was wondering if anyone has made experiments cheching exposure with a digital camera.

I have a Canon Rebel, and we are going to be using T200 Film.

I know the latitude is wider on film, but do you think is possible to "see" basic contrast and exposure using the Rebel on 200 ASA? or should i get a polaroid with 200 ASA?

Thanks in advance
