I'm using 7.11. I have mp4, png, and wav files. Here's a link to the files. https://drive.google.com/drive/folders/1fnLXsytpA41y8i_FsMgrtbU0dQJrbPzO?usp=sharing
After I export the project, there is often pausing between the clips that wasn't there before. I'm not sure what the cause is. It doesn't make much sense.
The pausing occurs right at the start of almost every clip.
