Sometimes when I'm editing the shorts, i cant see the results properly until I hit the save button and the damage has been done, specially when i need to cut a part of the video.
Specifically what happens (At least in Portuguese language) is that the video and the audio will not sincronize, the "soft fix" that happens is that it will loop the last few frame of audio until the video can catch up.
This is no good when I need to see if the if the cut happened at the end of a phrase or in the middle of a word.
