I have a sequence I put together and I was trying to gaussian blur in the first clip along with a dissolve in as well. Anyways, I tried keyframing the blur at the beginning and then when the blur would end but the whole clip stays blurred throughout even if I render(wanted to make sure it wasn't some kind of graphics issue in the preview only). I tried doing the same with opacity for the fun of it and it ignores any changes I make. Yet if I go to the second clip(and they are on the same track) it works fine. Is there a lock I may have put onto that clip to stop it from using keyframes or something? I have an unsharp mask applied and curves, + a dissolve at both ends plus a title on the track above. Any insights would be great.
If memory serves, there is some kind of bug here. You may have to experiment with different methods to achieve the desired result - nesting, exporting a DI, order of effects, etc.
Sorry I could not replicate. Make sure that you have a timeclock icon depressed.
