I'm using 4.33 of VP and have the following 'issue' when previewing my sequence.
Having added various transitions to the clips on my video, why (after the initial 100% CPU usage as it presumably creates the preview) does it say "Building preview, please wait" or similar every time that I then watch that video sequence?
The CPU is idle (which indicates to me that there is no outstanding work to do) but I hit the space bar and I get that message and the effect (a simple dissolve, a wipe from right) is not shown (I get a frozen image) as that message is displayed. Drives me nuts!
Eventually, after several attempts at watching the clip(s) with the transition it sorts itself out (and the final video always seems to be fine) but why this "Building preview" message? Is there anything I can do to assist (I've already reduced the preview resolution to far below what I'd like it to be, to see if it helped - it didn't).
Perhaps 4.40 cures this but it's not mentioned on the release notes.
