I trimmed 1 second from the beggining and its still 200MB, link to the file
is below

https://www.dropbox.com/s/l4seemgi3z38ueq/trim.mov?dl=0

The exact size of the original file is  1.MOV - 29,094,005KB This issue
occurs on all the files I recorded at 4k, the sizes are listed below

2.MOV - 311,185,558KB
4.MOV - 41,987,648KB
5.MOV - 121,165,767KB
