Many thanks for the reply.
Please watch the menu markers so that they are not on top of one another...especially if you are dealing with stop markers near scene markers. Several frames away from one another should be OK. Just do not place a stop marker at the end of the last file on the Timeline. It is not needed there and causes many types of problems.
The usual problem focuses on fragments from moving/arranging clips in the Timeline. They typically present as very thin black vertical lines scattered among the track content. They are difficult to see. So you will need to move the Zoom out/Zoom in slider all the way to the right to expand the Timeline to the maximum so that you can see them. Often these fragments are at the end of the Timeline. A good way to catch them is to
a. move the Timeline Indicator to the beginning of the Timeline
then
b. press the End key of the computer keyboard - that should take you to the end of the Timeline content (last file). If the End Command takes the Timeline Indicator beyond the last file, then it is taking you to where a fragment exists.
Also, double check the placement of transitions.
We will be watching for your progress.
Thank you.
