Now the worsening progression occurs when I am reaching around the 9 minute mark in the timeline. It's incredible how many starts, stops, black preview screens, lagging response to my click selections: click on a clip, wait for response, click on another clip, wait again, add an effect, it won't play, add the effect next to it and it does play. Finally (many, many times) Windows says PD9 has stopped working and PD9 closes; a generous reply from the CLForum and got rid of the last five edited clips and was able to keep PD9 from closing. Decided to finish this project at the timeline 10 min. mark because the response to my click (selecting a clip) would take from 4 to 12 seconds.
Have always had the problem of selecting a clip and the preview screen shows up black with the crosshair and circle, go back to another clip and that one previous then, go to the one I want to see in the preview screen.....
One very good thing is the CLForum which is very helpful but, even the experienced ones cannot fix the myriad of issues which are compounded by the myriad of PC configurations. This makes me wonder how there are tons and tons of software out there which do work with all those PCs.
The philosophical view is that video editing is still at a developmental stage and that you get a lot for $90.00, albeit, not fully developed and working.
I for one will continue trying for I don't know how long and start looking at other video editing software and their prices.
