smoothcam - form analysis complete to unanalyzed

[Tim Pearce]

Help. This is my first time really using Smoothcam filter in FCP6 and I completed analysis on a number of shorter test clips and experimented with the settings without problem. I then set the larger clips to be analyzed and few were done well and again I changed the settings of the clips that have been completed. I was very surprised when I returned to find out that some of the master clips that were listed in the Browser's "Smoothcam" column as completed have now returned to "unanalyzed" as if nothing has been done. Some of the clips had been put into sequences and cut into sub clips while the rest were still whole master clips. I queued one of the "unanalyzed" clips again for smoothcam. I'm afraid that some of the other completed master clips (as well as the ones still being analysed from the initial batch) will change. These master clips take so long and I'm afraid of wasting a lot of time. Any idea what is happening? I checked the finder and the .mtdf files are still there.
