HVX200 shooting in bright sunshine

I am trying to shoot some greenscreen stuff outside in 108024pa, but its so bright out( sun is behind me).

The only thing that works is using a 1/1000 shutter speed, and I can get good keys, but I have no definition in the talent, there is a lot of noise in the footage, especially with the talents black shirt, it just looks noisy.

Any suggestions

Regards

You shouldn't be doing greenscreen outside. You need to keep a nice, even, consistent light on the screen, and that won't be possible to do outside -- the lighting will change constantly.

Also, you want to light your screen and your subject separately, so you can control the exposure on both separately. You also want to be lighting your subject so as to match your intended background, and that's probably going to be pretty hard to do outdoors; you have much less control over your light.

Besides, the whole point of greenscreening in the first place is to control the lighting on your subject so that you can place them into a different background, including outdoors. :) You're defeating the purpose a little bit by shooting it outdoors.
 
David,
Thanks for the input. We tried inside using 3 point lighting( 2 500w diffused w/umbrella@3200K for screen, 1 500W for talent), but didn't have enough light for talent, and couldn't pull good keys.

Outside, everything seemed evenly lit, and keyed great, except for the talent.

So say I'm not shooting green screen outside, just footage, how would I setup the camera?

The only way I can get the camera to stop flashing to the noise reduction is to put the shutter to 1/1000 and manual iris 1 above fully closed. But just doing test shots of my dog shows washed out background and the talent is blocky.

I guess my question boils down to how to run-n-gun on a bright day and have the footage look presentable.

Have you tried using the built in Neutral Density filters? Or added a neutral density to your matte box? This will reduce the amount of light coming into your camera- allowing you to open the aperture. Your target for your best image is in the 5.6 range.

If you are getting noise in your video you probably need to go back into the scene file settings and make some adjustments that will lead to less noise. There are many posts here on the forum that can guide you in the right direction if you plant to adjust your master pedestal, etc.

Going back to trying to set up a green screen outdoors- you really need to be able to control the light hitting the screen as well as your talent. The use of scrims, screens and flags will help- but as David mentioned- your best bet is to head back inside and set up the green screen and lighting properly.

Thanks Jim.
I'll take another look @ the scene files, I have only been using the stock ones, trying each one.

I am new @ this so I have just been shooting a lot of trial and error, fill up a card, transfer, use Raylight and view in quicktime, delete and do it all again. I figure its the only way to learn the gear.

I certainly have found a lot of ways not to shoot stuff ;)

I have tried the nd settings, but every time I use them the image is worse, especially clothing, like black t-shirts, its all grainy.

So instead of raising the shutter to 1/1000 for light, I should retry with the nd settings to keep my iris in the 5.6 range, and shutter @ 180 or 1/24(if shooting 108024pa)?

I guess I need to get some more lights so I can shot indoors(green screen).

On "Science of the Movies" they were shooting green screen outside so I thought that's what everybody did( for quick stuff)

Keep the shutter at 180 degrees, or 1/48 @ 24p. If you can keep the iris between f/2.8 and f/8, that's best. Don't use a shutter of 1/1000 or you'll ruin the motion in your shot.

Greenscreening outdoors in the shade can work. It's not easy to pull off in direct sunlight, but if the greenscreen is in the shade (or it's a cloudy/overcast day) then you can get some ideally even lighting on the screen.
