Final Cut Pro X footage glitching
I am trying to export a video that I have finished editing and since attempting this the clips seem to have corrupted or something?
Before exporting the clips they were completely fine but now there is some kind of glitch when playing them back in FCPX. It seems to be merging footage from the previous clip on top of the current one and create a very pixelated effect that lasts around a second and this seems to happen randomly.
They were all filmed on an IPhone 8 plus,
and my MacBook Pro (that I have been editing and attempted to export on) specs are:
MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)
Processor - 2.3 GHz Dual-Core Intel Core i5
Memory - 16 GB 2133 MHz LPDDR3
Graphics - Intel Iris Plus Graphics 640 1536 MB
I have attached a screenshot of what the glitch looks like below, any help would be greatly appreciated, thanks!
