I have shot some short video clips to incorporate into an AV. But some of them are too dark. Can anyone suggest a simple way to brighten them up? I have tried some free video editors but they seem very complicated, and don't appear to have this function. Would be very nice to be able to do it in PTE, but version 8 does not have this facility as far as I can see. I usually shoot MP4 and let PTE convert the file to a avi.
