I shot a video with my phone (LG G5) which was larger than 4GB, so the phone split it into two files. When I tried to import the files into Vegas Pro 13, it accepted the 1st file, but refused the 2nd with the message "The file could not be opened." I worked round it by first re-encoding the second file using File Converter (which uses FFMPEG), but that is obviously not an ideal solution.
How can I fix this?
