Activity Forums JVC Cameras clipping problem with 700u

  • clipping problem with 700u

    Posted by Alan Hotchkiss on February 10, 2010 at 4:56 pm

    Just took delivery of the 700u. did some sooting and, unlike some of my experiences with other Hd cameras, like the Varicam, this camera clips out pretty harshly when overexposed. Instead of blowing out to white, the extreme over-exposed areas become a yellowish color. Anybody have some suggestions on how to get rid of this problem. Better yet, any suggestions of where I might go to get a hold of some nice setups I can experiment with. thanks!

    Alan,
    I talked with a JVC rep and he recommended the follow setup in the Camera Process:
    – Drop the master black to -1
    – Adjust the knee to manual and set at 90%
    – Bump the Color Gain to +3

    I’ve been using this set up for a while and like it better than the defaults. I have noticed that when you blow out the highlights they still turn yellow, so I’d be interested if you find a way to overcome that.

    Thanks
    Jon

    Thanks Jon. I’ll try these settings out. Do you have your camera set up in cinema gamma mode? I’ve also since changed our from the factory setting “standard” to “cinema”. I’m thinking this might smooth out some of the white and black curves to avoid the extreme clipping in the highlights. then again, I’m no engineer when it comes to this stuff.
    Any other thoughts out there 700u owners?

    I’m currently still in standard mode.
