Keeps crashing

I love this app but after videoing a project that is 40 minutes and 9Gb it keeps crashing and wont let me copy to my computer. I was able to save to my camera roll and then go back in filmic to trim it down and now it just crashes over and over. Ive tried syncing, rebooting, killing the app everything.
