I had the same problem on a PAL doc I was cutting. In that case everything was in DV, so lower field. I exported to Uncompressed PAL for the color grade on Digibeta, so upper field. And got the flickering on the slo-mos. However, the shift field filter fixed most of those errors since the slo-mo had already been rendered. This seems to confirm what Michael said. But some shots jsut wouldn’t be fixed. I was dealing with archival footage that had been transferred through innumerable processes. For a few shots I had to go back to the original lower field shot, de-interlace and export a new upper-field quicktime before doing the slo-mo. That was all in 5.1.4 land when FCP didn’t automatically apply the shift fields filter.
