•• fluorescent headache ••

I used to be able to play around with LIVEVIEW and AE Lock and point at different parts of a room with fluorescent lighting in order to get rid of the ugly brown rolling lines running vertically thru my screen.

Today I shot at a building that had so many fluorescent lights that no matter what I did, I had those brown lines travelling all thru my video. Is there a sure way of getting rid of these. Maybe I am doing something wrong here...I knew it was easier to deal with it.

Can someone remind me the steps to get rid of this uglyness?
 
Try something else instead: Forget the AE lock method for now and check if changing exposure compensation while being in Liveview removes them. As soon as they disappear, AE lock this setting and then change aperture on your lens as you normally would do. I've tried it several times at home and managed to fully remove those lines.

My theory is that by changing exposure compensation you both change shutter speed and ISO. Because the camera does both automatically for you, you can't change them separately. As soon as the shutter speed gets in sync with the artificial lights wavelength the lines should dissappear and you can AE lock that setting.

Good luck!
 
hi.
just wait for that manual firmware update nikon announced recently.
as soon as manual shutter control can be acheived, this problem should be solved.

exposure compensation? where is this?
also, how is your software coming along...the jello killer? Is it for FCP?
 
Yes, I meant the +/-, and yes Matt is also right.


It's not a "jello killer", it can only make some "jello" less prominent (it depends on how well camera movement gets detected). It's simply a batch script using methods, scripts and plugins already out there. It's not meant to be a plugin for FCP or other video editors, but a tool you run on your raw avi files before going into your editor of choice. I was planning on programming it in java but haven't have time to even start, so it's currently still using batch files as a "proof of concept". I don't even have access to a Mac, so currently I can't plan support for it.

I'm really looking forward to what "The Foundry" will have to offer as fix to "jello":

Hopefully, Nikon will release a miraculous firmware fix which will eliminate all our problems and needs for alternative methods (fingers crossed).
 
The level of "fixing" that we need to endure to have usable footage is quite silly when you think of it.... It's about time the next gen is released. Seems as though these cameras are causing more issues than solving. And panasonic was soo close so it should be only a matter of months until either RED or Nikon or even Canon gives us what we desire.
