iMovie does not export long videos!

[iMore Question]

I'm editing a 77 video file on iMovie on my iPhone4S, and at the end of exporting it tells me that there is not enough space on my device to export this video. Now the problem is, there is more than 10 GB free space on the phone AND after two times exporting (which takes about an hour and gives me the disappointing message in the end) there is about 1 GB of my space reduced! So something is taking that space up, and I reckon it's the exported video, but I have no access to it, coz it either does not exist, or it's hidden somewhere I can't reach with my phone or iTunes or one free app that I used; FileManager.

If anyone knows what I should do, please help me!

Hello and welcome to iMore! ... Have you tried rebooting your 4s? Is the original file 77 megabytes? (Very Small) or 7.7 Gigs? ... I have noticed that when I reboot there are often times that memory magically is freed up.
