EX1 Sharpness settings??

[Ronnie Martin]

I have shot many green screens with the Ex-1, ex-1R, Ex-3 and PMW 320 which are basically the same cameras with no problems at all.

Most of the time when I see a bad green screen shot is when the subject and the green screen ware not lighted correctly.

Also, there are somne editing platforms that do not have optimum keyers.

My Editing platform has been for years Grass Valley Edius (curently 7.21). You did not state your editing software.

Bottom line is that there may be more than one problem with your green screen shots.

Be sure to review your lighting techinques before blaming the camera.

Hope this helps

I am NOT blaming anything I was given advice from others on Creative Cow regarding the problem. So before you comment anymore see what others have said regarding my initial question a few weeks ago

Sorry if I hit a nerve with my response to your request for advice on your problems with green screen shots. In the future if I see you asking for advice I will surely not offer my help.

It is just my experience that many times when I am having a problem with something I go back to the basics and find that it was pilot error on my part. If I have all the basics in order then I proceed to each facet of the problem at hand.

Perhaps I am not as proficient or experienced as you and others on the forum. I have been at this for a long time.

I was just trying to help….

Hope you find the answer to you problem.

Take care

You didn’t hit a nerve at all. I was just told by someone on the forum that the problem was the sharpening that the camera internally adds in situations like that. I also had feedback saying that the green screen was correctly lit hence I thought I would put a post to try and sort out the sharpening problem.

So you would say that the camera doesn’t put on an internal sharpening??

With no reference to the above thread, I too pull a perfect key from my EX1 with the default settings.

Answering your specific question: You can’t adjust the sharpness in the default mode. It’s only available when you choose a Picture Profile. There is a button below the power switch to access them (the print is probably worn off like mine), you then choose a “profile” with the thumbwheel. Choose one, select “Set. ” Lots of options for each profile.

Not wishing to barge in on something that I don’t quite understand, but I’m amazed that people use this wonderful camera without taking an opportunity to view the splendid and detailed workshop on the camera by Doug Jensen in his DVD by Vortex Media. He is a master at explanation and covers almost everything that a prospective user might need to know, including a detailed exposition on Picture Profiles.

After investigating further I have looked at the camera and the Picture Profile was actually set to OFF so how did the camera apply that black line detail on one edge of the talent I have mentioned before?

[Steve Kownacki]

Can you post a screen grab of the raw footage.

At the minute no I’m on something else but the screen grab to the edge problem I had can be seen here.

That does have to do with the lighting, but it appears to me that it is in the way it is keyed/software settings. I’m not sure what AFX calls it, but in Premier I use the Ultrakey, aggressive, and tweak from there. I’m interested to see if the black edge is there in your raw, that’s what I understood your issue to be. For your key, you may need to duplicate the layer and use a mask to set a separate key for each edge of the talent.
