App crashes when rendering for export
I am using the iPhone 11 Pro. I have 4 video clips os varying length that I've put together from footage taken on my GoPro. Some is 4K some is 2.7. 24 FPS. It's all cropped to one aspect ratio. There is no audio- no music and the audio on all the videos is muted. The only effect I'm using is to speed up the clips. Total length of the video is around 3 minutes, and I'm trying to export in 1080 with original frame rate. I've also tried exporting in every other available frame rate to no avail.
When the export bar is nearly full, the app simply closes. No error message, nothing. It just crashes. Why??? This is such a waste of time if you can't export. Why would I ever pay for this if I can't?
