I'm having a slight problem, after rendering out text as well as some 3D elements I am geting a flicker, it only occurs with elements that have a spinning or rotaing motion on them, is there anyway to correct this?
1. Rendering settings and intended output matter. Are you getting flickering watching an interlaced animation? It won't look right on a computer monitor, but so long as the field order and frame rate are correct, it'll look fine on a television.
2. Antialiasing settings. Using a softer setting may look too soft on a computer monitor, but on an interlaced monitor, it works wonders.
Does this help? If not, be more specific with your situation and we may be able to help.
Then I'd double check field order, frame rate to be sure they're compatible with ntsc. You might also try smoother antialiasing settings to soften the hard edges that may "ring" or flicker. It might help to know exactly what is flickering... very small text or very fine horizontal lines have a habit of doing this... red colors are prone to bleeding.... there are other gotchas... but more detail might help find yours quicker.
