I created 2 lower third video's and exported as mp4. If I play them in windows default player they work fine.
I created a test project, imported a single video clip then both lower thirds and all worked as expected.
I then opened an existing project that has aprox 20 video clips in, all trimmed with transitions. When I add the lower thirds they don't work correctly.
One of them the start is missed off and the other the end is missed off - both clips are the correct length but don't play correctly.
If I open them in the trimmer they work as expected, it's just that when I add them to the timeline they don't.
Anyone seen anything similar before?
