File on my FMU is WAY over 2GB - FCP 7 crashes after 20 minutes - Never had any issues capturing before - Any suggestions on converting file, splitting file....anything to allow capture?

I have had ClipWrap bail me out of a jam recently.

I thought I'd had StreamClip convert files directly, but when I tried it again yesterday it didn't work. It's possible I was only imagining it.

Your file could be corrupt. In such case, you can preview its content with Treasured:
Treasured • Tool for Video Diagnostic and Repair (http://aeroquartet.com/movierepair/download.html) (free Mac app)
or with this diagnostics web page:
Video Repair Tool (http://mp4repair.org/preview.html)

Based on what you find, several course of actions are possible. Please let us know.
