Hi borate
Thanx again for your help.
Right now I have succeded in editing my project. I have segmented my source video file into 52 sequences without any problem, and the previewer works fine. I have exported all the sequences as MP4, and have tried closing the project file and opening it again. No hazards, all worked.
In my view the medicine, that worked, was reinstalling the source file, so it got indexed anew.
Perhaps one could suggest the programmers to make a button called eg. "refresh", "reindex", "reload" or something like that.
So for the time being, I am happy.
I will try vers. 16.02 again and with the file you sent me.
Is there a possibility in VP to save project files in older formats?
In my early attempt at editing, I changed the start and end of the source file several times and used this in the sequences. Perhaps this procedure confused the VP previewer.
In my latest successful attempt, I put the entire source file on the time line of the sequence, and then changed start and end. So this way the start/end of the source file never was changed.
Also I am not sure that "erase unused cache file" removes all. Perhaps it would be useful to be able to erase all cached files?
Kind regards
Hans
