Elements 11: How to edit an already formed time lapse video?

Please mark this question as correctly answered, brian.

I don't see anything in there that would indicate an issue with the file (other than it being a 35 minute video), Brian. But try converting the file with the free download Handbrake to see if that makes it editable.

Here's a tutorial I created on how to do that.
