Another thread talked about stabilizing graphics to get rid of flicker on sharp contrasts. We had the same issue with still pictures in a montage, and tried many of the techniques, such as setting the de-interlace switch, etc.
While on a picture's switch menu in Vegas 9.d., noticed a "Loop" switch that, with de-interlace, appeared to clean up the picture nicely.
What does this Loop switch really do? The "Help" function was helpless.
