Have specific problem in my 2 last projects. After rendering have some clips in timeline just keep freezing. When I play the preview video there is no problem, but after render there it is!
This started happening after I started using longer source files and just split them in timeline (erasing the parts that are not interesting). Before I would created subclips from bigger files and then edit them but I found that it is faster to just use the big source file and edit and split it directly in timeline... Could this be the problem?
Anyway, You can see the problem here...
