Dafydd (or anyone else),
Apparently direct, specific questions like the 4 I posted above are not supposed to be asked as I never got direct answers or sugestions, so far.
Meanwhile I attempted to create m2ts videos out of mov's and replaced them in my current project. Then I also tried to use James' suggestion. For a while I thought both helped. Then my audio-slip problems returned. (other disgusting problems are audio clips linked to upstream vidoes instead of the correct one just above it! Today I corrected about eight clips like these in a row - click on one adio and a video upstream highlights.) I could deal with this problem, but when PD shows me that an audio is in one place (the correct place relative to its video), yet the preview playback is heard seconds shifted, I am distraught. As I try to correct the problem, I am moving audio that is not really there and moving it elsewhere. That seems to lead eventually to a crash of PD if continued very long. Also, twice now, I've had the project so hosed that, when I try to open it again, PD crashes as soon as the timeline is populated. That version of my project now is forever unusable because it will continue to crash PD upon opening it. A window appears each time asking me to report information about what I was doing to cause PD to go away.
Today I continued with my projects because I must get done with these soon. All along I used to highlight, with clicks of the mouse, a series of stills and video to drag them to another place up or down stream. This time I decided to try to highlight with the slider and use the cut-and-paste option. This at first seemed to work OK. But later the problem appeared again. Then I noticed that moving a still upstream caused only the nearby video to move and the audio to stay in place, despite picking the "move all clips in all tracks option." Perhaps there is a bug in some of those situations.
Then I happened to highlight several stills to change their duration down from 4 to 3 seconds in one step. This caused the downstream video clip to move upstream, leaving the audio in place. Another perhaps not consistent error example when editing.
Because in the "heat of creation" I don't watch what is affected downstream, the accumulation of a variety of edits with many glitches like these, my PD file get's cluttered with errors and may even cause a crash.
It is so disturbing to have done a lot of editing, only to find that I have to drop back to a PD-saved copy and try to remember and redo all the creative changes I made in the previous hour or so.
I find it astounding that you can not replicate these problems. So what part of the workflow of mine is wrong? Although other products' problems in previous years drove me to PowerDirector, all these edit steps never gave me problems before. Fortunately PD's other wonderful features makes me continue with it - the most easily used product to produce good shows.
Any more ideas to share?
(I'll not be able to respond for the next week or so, should you be so kind as to help me some more.)
