What you're describing doesn't sound like the way Chroma Keyer should be used. You very likely shouldn't be animating the Color Range controls, which is the only thing I can think of that would cause what you describe.
Are you sure you're not referring to the Clean Plate part of Delta Keyer? If so, Clean Plate is meant to be used with locked off cameras and yes—a freeze-frame of the clean (or cleaned) plate. If the camera is moving, then you shouldn't use the clean plate workflow. Delta functions quite well without the clean plate input, although it might take a bit more work to manage edges.
edit: It can also be helpful to denoise a greenscreen plate more aggressively for keying than you do for the actual composite to reduce sizzle caused by noise.
